Carbonization Index and Energy Intensity in the Formation of Worldwide CO₂ Emissions, 1971–2000

This study uses three methods to explore the roles of the carbonization index and energy intensity in the formation of CO ₂ emissions throughout the world based on statistics from 1971 to 2000. The finding is that the role of both the carbonization index and energy intensity is the same in the formation of CO ₂ emissions. That is, they decreased CO ₂ emissions. However, the decrease of CO ₂ emissions caused by energy intensity is larger than the decrease of CO ₂ emissions caused by the decarbonization index. The estimated rates of the former to the latter are four times larger.

Keywords:

• energy-related CO₂ emissions
• carbonization index
• energy intensity
