Change Our World is a blog by Sam Carana, a prolific policy developer, analyst and sustainable world activist (see Change Our World: http://change-our-world.blogspot.com/2008/03/reduce-emissions-by-80-by-2020.html and Sam Carana on Gather: http://samcarana.gather.com/ ).

Sam Carana, “Reduce emissions by 80% by 2020”, Change Our World, 2008: “

James Hansen, NASA's top climate scientist, says in "Target CO2: Where Should Humanity Aim?" (see Target CO2: Where Should Humanity Aim? ) that the EU target of 550 parts per million (ppm) of CO₂ - the most stringent in the world - was not good enough, as this would cause the world to warm by 6C, rather than the previous estimate of just 3C. Hansen says targets should be slashed to 350 ppm … As the Environmental Protection Agency's inventory of U.S. Greenhouse Gas Emissions and Sinks 1990-2005 (see: inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2005 ) shows, well over 80% of US emissions are caused by fossil fuel - the mining of fossil fuel and burning it in power plants and in transportation. So, if we switched to electric vehicles over a period of a dozen years and to electricity produced in clean and safe ways, such as with wind and solar power, this would achieve an 80% cut by 2020. “ [1].
