america's share of the climate crisis


Greenpeace | Some key findings of the “America’s Share of the Climate Crisis” report include:

* Historically, no nation has emitted more global warming pollution than the United States. From 1960-2005, the U.S. emitted 213,608 MtCO2, 26% of total global emissions. The next biggest polluter, China, emitted 88,643 MtCO2 over the same time frame, 10.7% of global emissions.

* The U.S. also exceeded almost every other nation in per capita emissions. Per capita, the U.S. emitted 720 tons of CO2 per person per year from 1960-2005. This is more than ten times China’s per capita emissions(68 tons of CO2) during the same period, and ninety times the per capita emissions of Kenya (7.7 tCO2). Even considered individually, the 50 U.S. states are among the nations that are the largest emitters of carbon dioxideon earth.

* Even considered individually, the 50 U.S. states are among the nation as that are the largest emitters of carbon dioxideon Earth.

* The average U.S. state emitted 4,449 MtCO2 from 1960-2005, which would rank 30th among the nations of the world. The combined historic emissions of just seven states-Texas, California, Illinois, New York, Indiana, Pennsylvania, and Ohio-totalled 96,517 MtCO2, more than any other country in the world, including China (92,950).

* If Texas were its own country, it would rank sixth out of 184 countries in the world in total emissions, trailing just China, Russia, Germnay, Japan, and the United Kingdom.

* The overwhelming majority of global warming pollution in the U.S. comes from burning fossil fuels for energy. In 2007, CO2 emissions from combustion of coal, oil and natural gas accounted for 80% of total U.S. global warming pollution, with total CO2 emissions accounting for over 85% of U.S. global warming pollution. Power plants are the nation’s largest source of carbon dioxide emissions from energy consumption, contributing 42% of carbon dioxide emissions from fossil fuel combustion and 34% of global warming emissions overall.

* The transportation sector is the next largest source of carbon dioxide, contributing 33% of carbon dioxide emissions from fossil fuel combustion and 26% of global warming emissions overall. The remaining 25% of U.S. carbon dioxide emissions from energy sources comes from the direct consumption of fossil fuels in the commercial, industrial, and residential sectors.
