ABSTRACT
Rising rightwing populism (RWP) potentially constitutes an obstacle to climate change mitigation, as European RWP parties and politicians often espouse climate change skepticism and oppose climate policies. Meanwhile, their party positions and issue stances have also become increasingly characterized by nationalism. Using European Social Survey data from 2016, we show that public attitudes consistent with nationalist ideology are clearly linked to voting for RWP parties and that people who hold these attitudes are more likely to be skeptical about climate change and to oppose policies that increase taxes on fossil fuels. With regard to policy attitudes, we find that nationalist ideology is more influential than traditional left-right political ideology, environmental values and political trust. The results also reveal substantial cross-national differences, as nationalist ideology is linked more closely to public views about climate change in Western European countries, where RWP parties with a nationalist rhetoric have had recent electoral successes.
Introduction
Parallel to the increasing threat of climate change to human societies, many Western democracies have recently experienced a rise of rightwing populism (RWP) and increasing support for RWP parties (Inglehart and Norris Citation2016). Meanwhile, RWP politicians and the parties they represent commonly – if not universally (Ruser and Machin Citation2019) – express skepticism about climate change and oppose climate change mitigation policies, especially those that involve international and multi-national cooperation (Lockwood Citation2018, Hess and Renner Citation2019, Schaller and Carius Citation2019, Forchtner Citation2019a). This suggests that growth of RWP may constitute a significant obstacle to efforts to mitigate climate change (Schaller and Carius Citation2019).Footnote1
The theoretical literature has explored the linkages between RWP and rejection of the climate change agenda, that is, recognizing climate change as a serious problem requiring mitigation (Lockwood Citation2018), but our empirical knowledge both of how ideological orientations tied to RWP and support for RWP political parties influence public beliefs about climate change and support for climate change mitigation policies is very limited. This is especially notable in the Western European context where RWP parties have had considerable success during recent decades (Inglehart and Norris Citation2016).
An increasingly prominent feature distinguishing Western European RWP parties from other parties is their emphasis on nationalist themes such as opposition to multiculturalism and internationalism (Eger and Valdez Citation2019, see also Golder Citation2016, Woertz Citation2017). It is therefore not surprising that RWP parties and politicians frequently support local and national environmental policies that protect the countryside, nature and the ‘homeland’ (Schaller and Carius Citation2019, Forchtner Citation2019b, Tosun and Debus Citation2020), but often express skepticism about global environmental problems like climate change and oppose policies to address them (Forchtner and Kølvraa Citation2015, Forchtner Citation2019a). Those RWP parties and politicians who do acknowledge the reality of climate change tend to adopt a narrow ‘climate nationalism’ agenda which focuses on the limited measures their nations can adopt like improved public transportation, while rejecting supranational (global or European Union) policies (Ruser and Machin Citation2019, Schaller and Carius Citation2019). Although there is considerable evidence concerning the stances of RWP parties and politicians on the science and policy dimensions of climate change (Hess and Renner Citation2019, Schaller and Carius Citation2019, Forchtner Citation2019a), we know little about the links between attitudes consistent with key ideological components of contemporary RWP, such as nationalism, and beliefs about climate change and support for climate policies among the general public, especially cross-nationally.
We argue that there is a tension between acknowledging or acting on climate change and subscribing to several core tenets of nationalist political ideology. While the ideological underpinning of cosmopolitanism (i.e. that humanity constitutes a single moral community) constitutes a core imperative of the climate change agenda (Beck Citation2010), nationalism broadly defined represents the antithesis of cosmopolitanism in this regard; it prioritizes national interests over global concerns such as climate change. However, according to Calhoun (Citation1993, p. 215), ‘ … “nationalism” and corollary terms like “nation” have proved notoriously hard concepts to define’. Hence, nationalism can refer to a range of phenomena, involving for instance nation-building as well as identity-making processes (Gingrich and Banks Citation2006, Tamir Citation2019). We focus on recent forms of (neo)nationalism found primarily in many western European countries (see, e.g. Eger and Valdez Citation2019) that emphasize boundary maintenance by promoting the defense of national sovereignty as well as the pursuit of cultural protectionism and opposition to immigration (see also Gingrich and Banks Citation2006, Eger and Valdez Citation2015, The Economist Citation2015). These core tenets of nationalist ideology clash with binding international or European Union (EU) climate treaties and increasing flows of climate refugees, both of which are inescapable realities in times of intensifying climate change. Since nationalist ideology is not easily reconciled with accepting the climate change agenda, we expect those adhering to a nationalist ideology to be more likely to express climate change skepticism and oppose mitigation policies.
In this study, we extend existing cross-national research on public views about climate change and the roles of political ideology and political party support. These studies have demonstrated that political conservatives and rightwing party supporters, especially in Western Europe and Anglophone nations, are more likely to be skeptical about climate change and to oppose climate policies than their political opponents (McCright et al. Citation2016, Hornsey et al. Citation2018, Poortinga et al. Citation2019, Smith and Mayer Citation2019). Using European Social Survey data from 2016 covering 23 predominately European countries, we distinguish and systematically investigate the influence of nationalism, as a coherent and distinct political ideology, on climate change skepticism and opposition to climate policy. We also investigate the relationship between nationalist ideology and support for RWP political parties, and compare their respective importance for public views about climate change.
Finally, the prominence of nationalist ideology in RWP and other political movements, as well as the extent to which nationalist claims have been linked to issues of climate change in political discourse (for instance by RWP parties), very likely differ across national contexts. Consequently, we also investigate cross-national differences in the strength of the relationship between nationalist ideology and views about climate change. Due to the theoretical tension between nationalist ideology and the climate change agenda, combined with the prominence of nationalist ideology among Western European RWP parties, we expect a particularly strong relationship between attitudes consistent with nationalist ideology and views about climate change among the publics of Western European countries.
Previous research
Climate change skepticism
Previous research on climate change skepticism distinguishes between trend, attribution and impact skepticism, reflecting skepticism based on whether people think climate change is occurring, is human-induced and is harmful (Rahmstorf Citation2004, Poortinga et al. Citation2019). While majorities in most countries express belief in global warming, the role of humans in causing it, and its harmful impacts, a non-negligible share of the population in many countries still express some form of doubt or skepticismFootnote2 (Tranter and Booth Citation2015, Poortinga et al. Citation2019). The latter’s views stand in sharp contrast to the overwhelming scientific consensus about anthropogenic climate change (Cook et al. Citation2016). Given the discrepancy between the findings of climate change science and lay beliefs, a large number of studies have investigated a wide range of covariates associated with skepticism, such as demographic factors, environmental values and political orientation (see Hornsey et al. Citation2016).
Studies of Western nations find that the most crucial determinant of climate change beliefs is political orientation. Early research on the role of political ideology and partisan identification was conducted primarily in the United States of America (USA) and found that political conservatives and self-identified Republicans are considerably more likely than liberals and Democrats to express skeptical views toward climate change (McCright and Dunlap Citation2011), and this pattern has continued and even intensified (Leiserowitz et al. Citation2020). In the European context, however, polarization between left-leaning and right-leaning individuals appears to exist primarily in Western European nations, where it is much less stark than in the USA (McCright et al. Citation2016, Hornsey et al. Citation2018, Poortinga et al. Citation2019). An exception is the United Kingdom (UK) which, like the other Anglophone nations of Canada and Australia, has a level of polarization that is closer to that in the USA (Smith and Mayer Citation2019).
The relationship between political ideology and skepticism appears to vary even more in studies that include nations outside of Europe, North America and Australia (Tesler Citation2018, Lewis et al. Citation2019). However, many comparative studies use broad, traditional measures of political ideology or partisan orientation. For instance, while a few studies include measures of ideological positions such as endorsement of free-market ideology (Smith and Mayer Citation2019) and commitment to democratic principles (Lewis et al. Citation2019), most employ left-right (or liberal-conservative) party identification or self-placement on a political left-right scale (for an overview of earlier studies see McCright et al. Citation2016).
Another set of studies using non-representative samples (e.g. students) or representative samples from single countries finds that a number of political attitudes associated with RWP are related to climate change beliefs. For instance, in a longitudinal study of New Zealand undergraduates, Stanley et al. (Citation2017) find that rightwing authoritarianism, measured with a 30-item scale, has a strong and consistent impact on climate change skepticism. In another study, using a nationally representative sample from Norway, Krange et al. (Citation2019) find that people who oppose immigration in general are also more likely to endorse climate change skepticism. However, generalizability issues aside, it is unclear to what extent these attitudes represent key ideological tenets of RWP.
Attitudes toward climate policies
Fossil fuel taxes are often considered to be a particularly effective way of reducing greenhouse gas emissions since they impose the previously externalized costs associated with such emissions on those who emit, thereby making polluters pay for their harmful emissions (Fairbrother Citation2016a, Baranzini et al. Citation2017). Support for climate policies such as fossil fuel taxes has been tied to a range of variables such as climate change knowledge, beliefs and risk perceptions, perceived scientific consensus, basic values, and social and political trust (for an overview, see Drews and Van Den Bergh Citation2015, see also Leiserowitz Citation2006, Harring and Jagers Citation2013, Smith and Mayer Citation2018, Fairbrother et al. Citation2019).
Similar to the literature on climate change skepticism, research on attitudes toward climate change mitigation policies has identified political orientation as a key determinant of public support. For instance, previous studies of attitudes toward fossil fuel taxes have consistently demonstrated that conservatives and rightwing voters are more likely to oppose such taxes (Harring and Jagers Citation2013, McCright et al. Citation2013, Citation2016, Harring et al. Citation2017, Smith and Mayer Citation2018). In fact, previous research consistently shows that political ideology is an important driver of support for a wide range of environmental policies (for an overview, see Jagers et al. Citation2018), but that the effects of ideology (and related attitudes) on policy support differ considerably across countries (e.g. Fairbrother Citation2016b).
Most studies of support for climate (and other environmental) policies focus on individuals’ subjective placement on the well-known political left–right continuum (Fairbrother Citation2016b, Harring et al. Citation2017). A few studies also focus on more specific ideological dimensions, such as free market ideology (Smith and Mayer Citation2019), commitment to democratic principles (Lewis et al. Citation2019) or normative views about the role of government in protecting the environment (Kulin and Johansson Sevä Citation2019). Moreover, public support for environmental taxes and related policies is also heavily influenced by other factors associated with RWP, such as political (dis)trust (e.g. Harring and Jagers Citation2013). One study focusing on the willingness to pay higher taxes for environmental protection finds that ‘the importance of trust far surpasses that of political ideology’ (Fairbrother Citation2016b, p. 375, see also Fairbrother et al. Citation2019). However, few studies have focused on specific ideologies tied to RWP such as nationalism and how these ideological orientations influence climate change beliefs and policy attitudes.
Theoretical rationale
Lockwood (Citation2018) identifies two explanatory frameworks to account for the tension between RWP and ‘the climate change agenda’. First, according to a structuralist approach, RWP gains traction within the electorate among those who are marginalized economically and politically – i.e. those ‘left behind’ by globalization. In relation to climate change, however, empirical support for the structuralist approach is mixed, as studies have shown that socio-economically disadvantaged groups are not necessarily more skeptical about climate change or more hostile toward climate policies than are other groups (Tesler Citation2018, Lewis et al. Citation2019). Although structural factors may have fueled the rise of RWP, Lockwood (Citation2018) argues that the effects on public views about climate change are more likely due to the ideological content of RWP.
Proponents of RWP typically promote a presumed cleavage between ‘the people’ and ‘corrupt elites,’ indicating that anti-elitism and political distrust are key characteristics of RWP (Inglehart and Norris Citation2016). Such a conceptualization of RWP has led scholars to describe it as a ‘thin’ ideology, in the sense that it has to be filled with more concrete ideological content in order to become politically meaningful (Stanley Citation2008). A few recent studies have examined anti-establishment stances or authoritarianism and tied them to challenges in sustainable energy transformations or to environmental protection in general (Fraune and Knodt Citation2018, McCarthy Citation2019, Forchtner Citation2019a). However, studies that focus on specific ideological dimensions characteristic of RWP parties and investigate the relationship between individuals’ ideological orientations and their views about climate change and climate policies are lacking.
Recent research on the content of party platforms demonstrates that many RWP parties in Western Europe ‘increasingly make nationalist claims, articulating more support for a national way of life and greater opposition to multiculturalism, internationalism, and the European Union’ (Eger and Valdez Citation2019, p. 17). Some scholars even argue that nationalism is the ‘master concept’ of RWP, permeating party platforms and political rhetoric (Bar-On Citation2018). Results from empirical research further highlight the increasing prominence of nationalism in RWP, showing that nationalism has become a highly important ideological dimension among RWP voters (Eger and Valdez Citation2015, Lubbers and Coenders Citation2017).
We contend that the tension between RWP and the climate change agenda, to a large extent, is attributable to the prominence of nationalist ideology among RWP political parties. At the psychological level, different mechanisms could provide accounts of how this tension is manifested in terms of public beliefs and policy preferences in relation to climate change: for instance, as psychological defense mechanisms in response to an undesirable reality (Cohen Citation2013) or simply as an expression of conflicting interests between nationalist claims and the reality of climate change as well as its solutions (Lockwood Citation2018). In the following sections, we outline how and why several core tenets of nationalist ideology come into conflict with acknowledging and acting on climate change.
Nationalist ideology and climate change
Most definitions of nationalism entail ‘the pursuit … of a set of rights for the self-defined members of the nation including, at a minimum, territorial autonomy or sovereignty’ (Barrington Citation1997, p. 712). Considering that addressing the immense threat posed by climate change will require international cooperation and global agreements that infringe to some degree on national sovereignty, nationalists should be reluctant to recognize the threat posed by climate change or to support mitigation policies (Forchtner and Kølvraa Citation2015).
Nationalism also typically involves ideas about a homogeneous and distinct national culture and ‘a heightened concern that foreign influences erode the homogeneity and distinctiveness of national culture’ (Schatz et al. Citation1999, p. 155). Due to the inevitable consequences of climate change for displacement and transnational migration flows of climate refugees across borders (Davis et al. Citation2018), nationalists should therefore perceive climate change as a threat to their national culture. Furthermore, nationalism also tends to involve economic protectionism (Halikiopoulou et al. Citation2012). For instance, nationalists often view migration as an economic threat resulting in an increasing strain on national public finances (Colantone and Stanig Citation2019).
A central tenet of nationalist ideology centers on anti-globalism (Eger and Valdez Citation2019). As the public discourse about climate change and its solutions often distill into ‘national interest’ versus ‘thinking globally’ (Hovden and Lindseth Citation2004), those with a strong national and weak global attachment should be more likely to prioritize national interest over international cooperation in relation to climate change (Devine-Wright et al. Citation2015).
Voting for RWP parties
Previous research has shown that political communication and elite framing influence people’s concerns about climate change (Brulle et al. Citation2012) as well as public support for climate change mitigation policies (Linde Citation2018). Furthermore, when an issue is abstract and politically polarized, as is climate change, political allegiances and partisan cues are especially important (Guisinger and Saunders Citation2017, Tesler Citation2018). Given that RWP parties and politicians often display skepticism about climate change and oppose climate policy (Forchtner and Kølvraa Citation2015, Reed Citation2016, Schaller and Carius Citation2019, Lockwood Citation2018), the views expressed by RWP politicians and party platforms are very likely to influence RWP voters’ beliefs and preferences. Hence, in addition to the effects of nationalist ideology, support (via voting) for RWP parties is likely to be related to climate change skepticism and opposition to mitigation policies.
Data and methods
To study the potential influence of nationalist ideology and voting for RWP parties on public views about climate change, we use data from the European Social Survey (ESS) collected in the year 2016. The dataset is based on representative samples of the adult population across 23 predominately European countries (European Social Survey Citation2020). The study includes these countries (with abbreviations): Austria (AT), Belgium (BE), Czech Republic (CH), Estonia (EE), Finland (FI), France (FR), Germany (DE), Hungary (HU), Ireland (IE), Israel (IL), Iceland (IS), Italy (IT), Lithuania (LT), Netherlands (NL), Norway (NO), Poland (PL), Portugal (PT), Russian Federation (RU), Spain (ES), Sweden (SE), Switzerland (CH), Slovenia (SI), and United Kingdom (UK).
Dependent variables
We focus on two key outcomes in terms of public views about climate change, namely skepticism and policy attitudes. Building on previous research, we measure climate change skepticism by focusing on the critical dimensions of trend, attribution and impact skepticism (Rahmstorf Citation2004, Poortinga et al. Citation2019), using three items from the ESS asking respondents to what extent they believe that the earth’s climate is changing, that it is anthropogenic, and that it has bad consequences. In line with previous research using these items, a principal component analysis (PCA) finds only one latent factor, with strong factor loadings (>0.6) for all three manifest items (cf. Fairbrother et al. Citation2019), indicating that this underlying skepticism factor accounts for a considerable amount of variation in the manifest items measuring trend, attribution and impact skepticism. To capture individuals’ overall tendency to be skeptical about climate change, we use the standardized factor scores (mean centered, with a standard deviation of 1) representing each respondents’ score on this latent skepticism factor (higher scores = greater skepticism). We measure attitudes toward climate change mitigation policy using an item asking respondents if they favor or oppose increasing taxes on fossil fuels. For the analyses, we standardize this variable and code it so that higher values reflect greater opposition to fossil fuel taxes. In Appendix 1 of the online Supplementary Materials, we provide a more detailed account of question wordings, response scales, and coding of all variables included in this study.
Independent variables
To measure attitudes consistent with nationalist ideology, we use a set of items tapping the previously discussed dimensions of national sovereignty, cultural and economic protectionism, and national identification and attachment. Focusing on national sovereignty, such preferences are often manifested as opposition to the EU and the United Nations (Vasilopoulou Citation2009). To capture public preferences with regard to national sovereignty, we use two items asking respondents about their views on European unification and their trust in the United Nations. To measure cultural and economic protectionism, which often manifest in the perception that immigrants pose a threat to the culture or economy of one’s country (Mudde Citation2007, Schneider Citation2008, Eger and Valdez Citation2015), we use two items asking whether cultural life in one’s country is generally undermined or enriched by immigration and whether immigration is generally good or bad for the economy. Finally, we measure national identification and attachment by constructing a variable based on how emotionally attached respondents feel to their country relative to the EU. To capture individuals’ underlying tendency to embrace a nationalist ideology, we extract factor scores using PCA (yielding one latent factor, with strong or moderate factor loadings). High scores on the factor are indicative of nationalist attitudes.
To measure voting for an RWP party, we recode the country-specific voting variables in the ESS into political party families (cf. Mair and Mudde Citation1998), based mainly on the most recent version of the Comparative Manifestos Dataset (Volkens et al. Citation2018). However, due to dated information for some of the countries in the Manifestos data, we use additional sources to recode parties to align more accurately with their current content/focus (see Appendix 1 in the online Supplementary Materials for more detail on party coding and Table 1 in Appendix 2 for the list of parties in each country coded as RWP).
Control variables
To ensure that nationalist ideology (and its relationship to views about climate change) is not primarily a reflection of broader rightwing ideological orientations, we also include traditional political ideology in our analyses using an item measuring subjective left–right placement. We also include a number of control variables identified in the literature, namely social trust, political trust, and environmental values. For the analysis focusing on climate policy attitudes (support for an increase in fossil fuel taxes) as the dependent variable, we also include climate change beliefs (level of skepticism) and concern (level of worry about climate change). All variables are standardized (z-scores) – that is, grand means centered with a standard deviation of 1. Finally, we also include the demographic variables gender (1 = man, 0 = woman), age (in years), and education (in years) as controls.
To study the effects of nationalist ideology on beliefs about climate change and climate policy support across European countries, we use multilevel analysis (Snijders and Bosker Citation2011). This enables us to not only take into consideration the nested structure of the data (individuals nested in countries), but also to estimate random effects with regard to nationalist ideology. Estimating random coefficients means that the slope for the effect of nationalist ideology is allowed to vary cross-nationally, thereby enabling assessment of differences in effect sizes across countries. We then use both fixed and random coefficients to assess the overall impact of nationalist ideology on climate change beliefs and policy preferences cross-nationally.
Results
We first examine the cross-national salience of nationalist ideology as well as its relation to voting behavior, with a special focus on voting for RWP parties. In , the mean factor scores reveal major cross-national differences in the extent to which people adhere to nationalist ideology, most notably between Eastern and Western Europe. For instance, while the mean factor scores are relatively high in many Eastern European countries such as Russia, Hungary and Czech Republic, they are substantially lower in many Western European countries such as Iceland, Sweden, Spain and Finland. These cross-national differences reflect to a great extent the overall cumulative salience of the attitudes underlying the measure of nationalist ideology (see Supplementary Materials, Appendix 2, ).
Turning to the relationship between nationalist ideology and self-reported voting behavior, we expect endorsement of nationalist ideology to be higher among RWP voters than those voting for other parties. However, considering that previous research linking RWP to nationalism has found this link mainly in Western Europe, we examine the relationship between nationalist ideology and RWP voting in Western and Eastern European countries separately. ,b) show the means and confidence intervals (95%) for our nationalist ideology measure across different political party families. The results show that people who vote for RWP parties in Western Europe are considerably more likely to hold attitudes consistent with nationalist ideology ()). In Western European countries, voters for RWP parties on average score approximately 0.7 to 1.1 units or higher on the nationalist ideology measure compared to voters for most other parties and even higher relative to supporters of Green parties. In contrast, people who vote for RWP parties in Eastern Europe are not such strong outliers in terms of nationalist ideology (Figure 2 (b)). In Eastern European countries, voters for RWP parties on average score only marginally higher than voters for most other parties and even score lower than some other parties’ voters (e.g. Left). These results indicate that nationalist ideology, at least as we measure it here, is closely linked to RWP politics in Western Europe (Eger and Valdez Citation2019). However, the results also show that nationalist ideology is not exclusive to RWP voters, and that these ideological views exist at least to some extent among many voter groups, especially in Eastern Europe.

We now continue with the main part of the analysis centering on the influence of nationalist ideology on public views about climate change. Focusing first on the results for climate change skepticism, we present four models in where a model including all control variables except RWP voting (Model 1) is complemented with models introducing nationalist ideology and voting for an RWP party separately (Models 2 & 3) as well as together (Model 4). The results show that nationalist ideology is positively associated with climate change skepticism, even when controlling for RWP voting (Model 4). In fact, when included in the same model, the effect of RWP voting is slightly reduced from Model 2 while the effect of nationalist ideology is consistently strong (and even increases from Model 3 to 4), indicating that nationalist ideology is a more important predictor of climate change skepticism than is RWP voting. Furthermore, the effect of nationalist ideology is also notable relative to the effect of traditional left-right ideology (even though the latter’s effect is larger in Models 3 and 4), since it demonstrates that nationalism’s unique ideological influence on climate change skepticism cannot be reduced to the standard political left-right orientation.
Table 1. Multilevel analysis: climate change skepticism
Further, unsurprisingly we find a strong negative effect of environmental values on climate change skepticism, as people who value the environment are less likely to express climate skepticism. Finally, in contrast to expectations, we also find that higher levels of social and political trust are associated with greater climate change skepticism. While surprising in light of prior studies showing the generally positive effects of trust on, for instance, climate change mitigation behaviors (e.g. Cologna and Siegrist Citation2020), these results fall outside the focus of the present study but deserve further attention in future studies.
In , we present corresponding models for climate policy attitudes, that is, opposition to increasing fossil fuel taxes. These models add climate change skepticism and concern (level of worry) as controls, since it is reasonable to assume that policy attitudes at least partly reflect people’s beliefs and concern about the problem that the policies aim to address. The results show that nationalist ideology is positively associated with opposition to increasing fossil fuel taxes in both Models 3 and 4, and that the effect of RWP voting is reduced once nationalist ideology is introduced (compare Models 2 & 4). With regard to effect sizes, the estimates for nationalist ideology demonstrate that it is the most important predictor in our models of policy attitudes, surpassing the influence of other key predictors such as traditional left-right ideology, environmental values and political trust. Thus, people who adhere to nationalist ideology are especially likely to oppose increasing fossil fuel taxes, a key mitigation policy. While previous studies of support for environmental taxes have found that political trust and traditional political ideology are some of the most influential determinants (Harring and Jagers Citation2013, Fairbrother Citation2016b, Fairbrother et al. Citation2019), our results suggest that nationalist ideology constitutes a crucial and previously neglected determinant of climate policy attitudes. All control variables have statistically significant effects in the expected direction, as social and political trust, environmental values, and climate change concern are all associated with lower levels of opposition to increasing fossil fuel taxes, whereas climate change skepticism is associated with greater opposition.
Table 2. Multilevel analysis: opposition to increasing fossil fuel taxes
The results presented in imply that the ardent opposition to increasing fossil fuel taxes among people who adhere to nationalist ideology cannot be accounted for solely by their skeptical beliefs about climate change. To examine this puzzling finding in more detail, we investigate whether the strength of the relationship between climate change skepticism and opposition to increasing fossil fuel taxes is tied to individuals’ adherence to nationalist ideology. In , we plot the marginal effect of climate change skepticism on opposition to increasing fossil fuel taxes at different values on the measure for nationalist ideology.
Figure 3. Marginal effects of climate change (CC) skepticism on opposition to increasing fossil fuel taxes at different levels of nationalist ideology (factor)
![Figure 3. Marginal effects of climate change (CC) skepticism on opposition to increasing fossil fuel taxes at different levels of nationalist ideology (factor)](/cms/asset/1e5995eb-b3e6-4575-8426-43fd66a70606/fenp_a_1898879_f0003_b.gif)
shows that the relationship between skepticism and opposition to increasing fossil fuel taxes is weaker among those embracing nationalist ideology and non-existent among those who score highest on the nationalist ideology measure.Footnote3 This means that the relatively strong opposition to increasing taxes on fossil fuels among strong nationalists cannot be attributed to their levels of climate change skepticism. Rather, our results suggest that nationalist concerns, rather than beliefs and concern about climate change, influence policy attitudes among those with strong nationalist leanings.
Finally, to take into consideration the cross-national differences in the effects of nationalist ideology on views about climate change, we present the total effect sizes for individual countries, based on both fixed and random effects in ,b). As shown in ), the effects of nationalist ideology on climate change skepticism are strong in several Western European countries – especially so in Norway, Finland, Sweden, Iceland, Belgium and United Kingdom. Meanwhile, in many Eastern European countries such as Russia, Hungary, Czech Republic and Lithuania (but also in Austria and Italy), the effects of nationalist ideology are negative, which means that nationalist ideology is associated with less skepticism in these countries. Another noteworthy finding is that the positive effects of nationalist ideology on climate change skepticism are strongest in the four Nordic countries in our study (Norway, Finland, Sweden and Iceland), which are all countries that display low average levels of nationalist ideology (cf. ).

Focusing on opposition to increasing fossil fuel taxes (Figure 4 (b)), nationalist ideology is associated with greater opposition in all countries except in Lithuania (where a relatively weak negative effect is found). However, as with climate change skepticism, the strongest effects of nationalist ideology are found predominately in Western European countries such as the Netherlands, Norway, Sweden, and Switzerland. Overall, the results in ,b) demonstrate that, while attitudes consistent with nationalist ideology are more widespread in Eastern European countries (cf. ), we find the clearest evidence of their link with opposition to a fossil fuel tax increase among the populations of Western Europe, where increasingly nationalist RWP parties have frequently had notable success in recent years (Inglehart and Norris Citation2016).
Discussion and conclusion
Our study contributes to the literature on the influence of political ideologies on public opinion about climate change, as we identify nationalist ideology as an important predictor of two key public responses in this regard – climate change skepticism and opposition to increasing fossil fuel taxes. Our results show that individuals holding attitudes consistent with nationalist ideology – an increasingly characterizing trait of Western European RWP parties – are more likely to be skeptical about the realities of climate change, and substantially more likely to oppose increasing taxes on fossil fuels.
In fact, with regard to opposition to fossil fuel taxes, we find that nationalist ideology is the most important variable in our analyses, surpassing other key predictors frequently found in the literature, such as traditional left–right ideology, environmental values and political trust (Harring and Jagers Citation2013, Fairbrother Citation2016b, Fairbrother et al. Citation2019). Furthermore, since the effect of traditional left–right ideology is not substantially reduced when including nationalist ideology in our models, nationalism, at least as measured here, appears to constitute a distinct political-ideological dimension with a unique and independent effect on support for a key climate policy. This all suggests that nationalist ideology constitutes a crucial predictor of climate policy support that previous research has overlooked.
However, the relatively stronger opposition to increasing fossil fuel taxes among those subscribing to nationalist ideology does not appear to be explained by their higher levels of skepticism. Our results show that the relationship between beliefs about climate change and opposition to fossil fuel taxes is weak or non-existent among those who score high on our measure of nationalist ideology. This could at least partly explain why the link between beliefs about climate change and climate policy attitudes is surprisingly weak in many European countries (cf. Fairbrother et al. Citation2019).
Meanwhile, traditional left–right ideology is clearly more influential than nationalist ideology with regard to climate change skepticism, indicating that public skepticism is more strongly linked to mainstream political cleavages. However, when comparing the impact of nationalist ideology and RWP voting, nationalist ideology is more influential both with regard to climate change skepticism and climate policy attitudes. At the same time, the effect on skepticism is relatively weak, suggesting that the stark differences in climate policy attitudes (opposition to higher fossil fuel taxes) between those who subscribe to nationalist ideology and those who do not cannot be attributed to substantially higher levels of skepticism among the nationalists. Instead, our results demonstrate that, when those with strong nationalist leanings form their attitudes toward climate policies such as increasing taxes on fossil fuel, nationalist concerns appear to trump beliefs and concern about climate change. That a sizable share of the public sees a progressive climate policy agenda as challenging their strong sense of nationalism fits well with literature reporting that RWP parties and politicians may or may not express doubt or deny the reality of climate change, but nonetheless see many climate change policies as a cosmopolitan threat to national sovereignty (Forchtner Citation2019a, Kølvraa Citation2019).
Considering that the results differ across our two dependent variables, with weaker effects of nationalism on skepticism relative to its effects on policy attitudes, analyzing a more diverse set of public responses to climate change appears important in order to obtain a broader understanding of the impact of nationalist ideology on public views about climate change. For instance, since the effects of nationalist ideology on climate policy attitudes could vary in strength depending on the policy in question (e.g. taxes on fossil fuels versus subsidies for renewable energy), future studies should employ items measuring attitudes towards toward a broad range of climate policies. Future studies could also explore the role of nationalist ideology for personal behaviors that have important consequences for greenhouse gas emissions (e.g. reducing household energy use). Further, given our use of a composite measure of overall skepticism, future studies could also examine the relationships between nationalist ideology and specific dimensions of skepticism (trend, attribution, and impact).Footnote4
Our results are similar to previous studies using broader measures of political ideology, showing that political polarization (i.e. left-right differences) with regard to climate change skepticism is far more pervasive in Western than Eastern European countries (McCright et al. Citation2016, Lewis et al. Citation2019, Smith and Mayer Citation2019). However, our results show an even starker discrepancy between Western (especially Nordic) and Eastern European countries, as the effects of nationalist ideology on skepticism are not only considerably weaker, but in some cases even reversed, in several Eastern European countries. This indicates that, while we find a fairly consistent pattern across most Western European countries, these relationships do not appear to follow the same logic in several Eastern European countries.
A case can be made that the generally stronger effects of nationalist ideology on public views about climate change in Western Europe is attributable at least in part to cross-national variation in elite framing and political communication (Brulle et al. Citation2012, Tesler Citation2018). For instance, the articulation by RWP (and other) politicians of tensions between nationalist claims and claims about climate change – such as the threat to national sovereignty posed by international climate treaties – might be more salient in Western than in Eastern European nations. Although the increasing articulation of (neo)nationalist claims in Western Europe suggests that this could be the case, the Manifestos dataset is inadequate for such analyses, since negative mentions of environmental and/or climate change claims are not currently available. However, the consistent opposition to climate policy legislation among many RWP parties in the European parliament (Schaller and Carius Citation2019) nevertheless appears to support this notion. Future studies should therefore explore the role of elite framing and political communication in explaining cross-national differences in the ‘nationalism-climate change nexus’. Moreover, while the unexpected, reversed effects in some Eastern European countries are perplexing, and deserve more in-depth exploration, this falls outside the scope of the present study.
Finally, to the extent that the tension between nationalist ideology and policy attitudes also involves a wider range of climate policies (beyond fossil fuel taxes), many efforts to mitigate climate change may meet serious public opposition as a result – especially in Western Europe where this tension appears most pronounced. Moreover, if a rising right-wing populism with an increasingly nationalist agenda is accompanied by intensified articulations of this tension, implementing a progressive EU or global climate agenda may be stifled by even more widespread public hostility. Future research should therefore pay greater attention to nationalist ideology as a potential obstacle to the implementation of a wide repertoire of climate policies needed for successful climate change mitigation.

Notes
1. Schaller and Carius (Citation2019) provide a detailed review of 21 RWP parties and their climate change agendas, focusing primarily on party platforms and votes in the European Parliament. While they find varying levels of skepticism toward climate science, they find broad opposition to most climate change mitigation policies. In contrast, Ruser and Machin (Citation2019) focus on only three of these parties and highlight their differing stances on climate change, in our opinion underplaying the dominant pattern of skepticism and opposition to climate mitigation policies found among European RWP parties.
2. We use the term ‘skepticism’ in a broad sense, denoting beliefs that express different forms of doubt about, or outright denial of, the basic findings of climate science. In doing so we follow the widespread practice of using skepticism to describe public views while reserving ‘denial’ to describe the views and actions to actors involved in the promotion of climate change denial (Dunlap Citation2013).
3. We also ran this analysis replacing climate change skepticism with climate change concern (level of worry), which yielded similar results.
4. In a study of European nations, Poortinga et al. (Citation2019) examine different dimensions of skepticism separately, but their focus differs substantially from ours.
