By giving rich nations incentives to invest in green energy ranging from hydro to solar power, the programme aims to brake a build-up of heat-trapping carbon dioxide in the atmosphere from burning fuels such as coal or oil.
"The known project potential ... is presently estimated to generate around a billion tonnes of emission reductions by the end of 2012," the Bonn-based secretariat said in a statement.
That is the estimated reduction between now and end-2012.
Annual world greenhouse gas emissions from human activities -- mainly from fossil fuels burnt in power plants, vehicles and factories -- exceed 25 billion tonnes. About a quarter is from the United States.
"The one billion tonne mark in emission reductions corresponds to the present (annual) emissions of Spain and the United Kingdom combined," the secretariat said. Britain emits about 650 million tonnes of carbon dioxide, Spain 350 million.
