At a world level, CO2 emissions from energy use per unit of GDP (CO2 intensity) stands at 0.43 kCO2/$2005p.
It has fallen in all regions since 1990 except in the Middle East.
In OECD countries, CO2 emissions per unit of GDP are 20% below the world average, at 0.33 kCO2/$2005p. In the United States, CO2 intensity increased slightly in 2010, by 1.2%, to 0.42 kCO2/$2005p, compared with stagnation at 0.26 kCO2/$2005p in Europe.
Higher intensities were recorded in developing countries. CIS posted the highest CO2 intensity, with more than 0.8 kCO2/$2005p and growth of 2.4% in 2010. In the Middle East, CO2 intensity remained high at 0.66 kCO2/$2005p. In China, CO2 intensity dropped by 0.9% (0.79 kCO2/$2005p), despite a sharp increase in the country’s CO2 emissions. In India, a 3.5% decrease in CO2 intensity was achieved in 2010, down to 0.45 kCO2/$2005p.
