GREENHOUSE GAS EMISSIONS: Recently the World Resources Institute (WRI) updated its CAIT Climate Data Explorer on the world’s top greenhouse gas-emitting countries with the latest global data available (2013). An interactive chart on the WRI website explores the trends by country and by economic sector. As shown above, top emitters have changed in recent years:
1) The Top 3 Emitters Contribute 14 Times the Emissions of the Bottom 100
The top three greenhouse gas emitters— China, the European Union and the United States—contribute more than half of total global emissions, while the bottom 100 countries only account for 3.5 percent. Collectively, the top 10 emitters account for nearly three-quarters of global emissions.
2) The Energy Sector remains the Major Culprit
Over the past 10 years, the energy sector has remained the largest contributor to emissions over any other sector, representing 72 percent of global emissions in 2013.
3) Some Major Emitters are Reversing their Trends
Even with that growth of emissions from 2012-2013 by top emitters, if we expand the timescale, their combined emissions have remained the same for the past decade. In that time, the United States peaked its emissions in 2007, and the European Union, the third-largest emitter, saw steady reductions. Others have stabilized their emissions over the last 10 years, including Russia and Canada.
