Low hanging fruit (Freakonomics):
The world is full of efforts and estimates toward reducing carbon emissions. A new paper by David Wheeler and Dan Hammer argues that the best bang for the climate change buck may lie in family planning and girls’ education: $1 million spent could save 250,000 tons of CO2. Reducing slash and burn forest practices (the next expenditure category), in contrast, would only save only 66,667 tons. Other categories that produce less-efficient returns include pasture management, geothermal energy, pastureland afforestation, reforestation of degraded forests, plug-in hybrid cars, solar energy, power plant biomass co-firing and capture carbon and storage.
