2.0 degrees from pre-industrial levels — 1 to 1.5 from todays level — is a ceiling that some world organizations have viewed as troubling, but livable.
On a straight carbon dioxide emission basis, the United States accounted for 24.0% of emissions, highest in the world, and was 5th highest per capita in 2000 (only exceeded by Qatar, the United Arab Emirates, Kuwait and Bahrain).
European nations have suceeded in achieving a slight reduction in carbon emissions by switching from coal to gas for power generation. Overall, their energy use is actually increasing.
Available statistics allow an analysis of carbon emissions by broad type of economic activity.
Currently, the only renewable energy source which contributes a meaningful portion of the nation’s and Massachusetts energy supply is hydropower.
