Global and regional drivers of accelerating CO2 emissions.
Global economy more carbon intensive, not less. A new analysis shows that carbon intensity in the world economy is increasing. While emissions of carbon dioxide (CO2) are accelerating worldwide, we are gaining fewer economic benefits from each tonne of fossil fuel burned. A study published this week in the Proceedings of the National Academy of Science shows that CO2 emissions increased by 1.1% per year through the 1990s but the rate of increase jumped to 3% per year in the 2000s.
