America's Share of the Climate Crisis
From 2009 :
This study aims to shed light on the United States’ responsibility for taking the lead to solve global warming as a result of its outsized role in causing the problem in the first place. Using data from the Carbon Analysis Indicators Tool maintained by the World Resources Institute, the analysis examines state-by-state carbon dioxide emissions from fossil fuel combustion from 1960-2005 and compares those emissions to 184 other countries of the world.

Historically, no nation has emitted more global warming
pollution than the United States. Over the past 150 years,
the U.S. has emitted 328,264 million metric tons of carbon
dioxide (MtCO2), the primary greenhouse gas, 29% of total
global emissions.
No other country in the world emitted
more than 8% of global emissions. China, the second-
leading global warming emitter in the world, trails far behind
with just 92,950 MtCO2 of emissions over the same time
frame. This legacy of pollution by industrialized countries
is the reason that they are obliged to cut emissions before
developing countries under the UN global warming treaty
(the Framework Convention on Climate Change.
Per capita emissions in the U.S. have historically been
far above most countries in the world as well. In 2005, the
United States emitted 23.5 tons of global warming pollution
for every man, woman and child in the country. Only Austra-
lia (26.9), the tiny principality of Luxembourg (27.5), and small,
oil-producing nations Qatar (55.5), U.A.E. (38.8), Kuwait
(35.0) and Bahrain (25.4) had greater emissions per capita
than the United States.
