Washington (AFP) The toolbox of international climate policy includes money from rich nations for climate action in poor countries. The fact that such projects are actually working has now been confirmed by a US study in the case of Norway's promotion of forest conservation measures in the small South American country of Guyana. Without the project, the clearing in Guyana would have been 35 percent higher and the emission of climate-damaging CO2 at least 12.8 million tons higher.
