The Earth Policy Institute is an environmental organization founded in 2001by Lester R. Brown, based in Washington, D.C., U.S.A., and dedicated to building a sustainable future and informing the public about climate change, population expansion, mass species extinction and other threats impacting upon Humanity (see Wikipedia: http://en.wikipedia.org/wiki/Earth_Policy_Institute and Earth Policy Institute: http://www.earth-policy.org/ ).
Lester R. Brown and colleagues, “Time for Plan B. Cutting emissions 80 percent by 2020”: “When political leaders look at the need to cut carbon dioxide emissions to curb global warming, they ask the question: How much of a cut is politically feasible? At the Earth Policy Institute we ask a different question: How much of a cut is necessary to avoid the most dangerous effects of climate change? … Cutting CO2 emissions 80 percent by 2020 will take a worldwide mobilization at wartime speed. First, investing in energy efficiency will allow us to keep energy demand from increasing. Then we can cut carbon emissions by one third by replacing fossil fuels with renewable energy sources for electricity and heat production. A further 14 percent drop comes from restructuring our transportation systems and reducing coal and oil use in industry. Ending net deforestation worldwide can cut CO2 emissions another 16 percent. Last, planting trees and managing soils to sequester carbon [biochar] can absorb 17 percent of our current emissions. None of these initiatives depends on new technologies. We know what needs to be done to reduce CO2 emissions 80 percent by 2020. All that is needed now is leadership. “. [1].
