Report: Few, Rich Countries Produce Most of Greenhouse Gas Emissions
- A relatively small number of countries produce a large majority of global GHG emissions, and most also rank among the world's most populous countries and those with the largest economies. The group includes almost an equal number of developed and developing countries, as well as economies in transition.
- Per capita emissions and per capita income vary widely among the major emitters, a group that includes some the world's richest and poorest countries.
- The group of top emitters varies little whether counting only carbon dioxide (CO2) emissions from fossil fuel combustion, or CO2 from land use change as well, or other greenhouse gases; or whether looking at present, cumulative or projected emissions.
