Carbon intensity is the ratio of carbon emissions to economic activity or some other activity. It is typically reported as the change in the ratio of the two. General Name, Symbol, Number carbon, C, 6 Chemical series nonmetals Group, Period, Block 14, 2, p Appearance black (graphite) colorless (diamond) Atomic mass 12. ...

Carbon intensity can also be a measure of carbon emissions versus primary energy. Primary energy is energy contained in raw fuels and any other forms of energy received by a system as input to the system. ...
Both measurements are a reflection of the efficiency of the economy with respect to carbon emissions which cause climate change. Variations in CO2, temperature and dust from the Vostok ice core over the last 400,000 years Climate change refers to the variation in the Earths global climate or in regional climates over time. ...
Carbon intensity, or "greenhouse gas intensity" is the measure of emissions used in the U.S. Clear Skies Act, which pledges to cut greenhouse gas intensity by 18% by 2012. The Clear Skies Act of 2003 is a proposed federal law of the United States. ...
Environmentalists have criticised carbon intensity as a tool for policy makers. Reductions in carbon intensity do not mean a reduction in actual carbon emissions. From 1990 to 2000 the carbon intensity of the U.S. economy declined by 17 percent yet total emissions increased by 14 percent. [1] In 2002, the U.S. National Environmental trust labelled carbon intensity, "a bookkeeping trick which allows the administration to do nothing about global warming while unsafe levels of emissions continue to rise."[2]
