Greenhouse Gas Emissions By The United States
The United States was the second top emitter by fossil fuels CO2 in 2009 5,420 mt (17.8% world total), and the second top of all greenhouse gas emissions including construction and deforestation in 2005 US: 6,930 mt (15.7% of world total). In the cumulative emissions between 1850 and 2007 US was top country 28.8% of the world total.
Until recently the United States for the country as a whole was the largest emitter of carbon dioxide but as of 2006 China has become the largest emitter. However per capita emission figures of China are still about one quarter of those of the US population. On a per capita basis the U.S. is ranked the seventh highest emitter of greenhouse gases and fourteenth when land use changes are taken into account.
According to data from the US Energy Information Administration the top emitters by fossil fuels CO2 in 2009 were: China: 7,710 million tonnes (mt) (25.4%), US: 5,420 mt (17.8%), India: 5.3%, Russia: 5.2% and Japan: 3.6%.
In the cumulative emissions between 1850 and 2007 the top emitors were: 1. US 28.8%, 2. China: 9.0%, 3. Russia: 8.0%, 4. Germany 6.9%, 5. UK 5.8%, 6. Japan: 3.9%, 7. France: 2.8%, 8. India 2.4%, 9. Canada: 2.2% and 10. Ukraine 2.2%.
The Environmental Protection Agency's Personal Emissions Calculator is a tool for measuring the impact that individual choices (often money saving) can have.

Famous quotes containing the words united states, greenhouse, gas, united and/or states:
“What chiefly distinguishes the daily press of the United States from the press of all other countries is not its lack of truthfulness or even its lack of dignity and honor, for these deficiencies are common to the newspapers everywhere, but its incurable fear of ideas, its constant effort to evade the discussion of fundamentals by translating all issues into a few elemental fears, its incessant reduction of all reflection to mere emotion. It is, in the true sense, never well-informed.”
—H.L. (Henry Lewis)
“There is not enough exercise in this way of life. I try to make up by active gymnastics before I dress when I get up, by walking rapidly in the lower hall and the greenhouse after each meal for perhaps five to ten minutes, and a good hand rubbing before going to bed. I eat moderately; drink one cup of coffee at breakfast and one cup of tea at lunch and no other stimulant. My health is now, and usually, excellent.”
—Rutherford Birchard Hayes (1822–1893)
“Man moves in all modes, by legs of horses, by wings of winds, by steam, by gas of balloon, by electricity, and stands on tiptoe threatening to hunt the eagle in his own element.”
—Ralph Waldo Emerson (1803–1882)
“It is said that the British Empire is very large and respectable, and that the United States are a first-rate power. We do not believe that a tide rises and falls behind every man which can float the British Empire like a chip, if he should ever harbor it in his mind.”
—Henry David Thoreau (1817–1862)
“The traveler to the United States will do well ... to prepare himself for the class-consciousness of the natives. This differs from the already familiar English version in being more extreme and based more firmly on the conviction that the class to which the speaker belongs is inherently superior to all others.”
—John Kenneth Galbraith (b. 1908)
