Technologies for Reducing Non-Energy-Related Emissions

Among the sources of non-energy GHG emissions from the advanced economies, agriculture is the largest, followed by waste and industrial processes.1 Gross nonenergy emissions are estimated to be 15.4% of all GHG emissions from the advanced economies in 2010. The relative importance of gross non-energy emissions in total GHG emissions is tending to decline because of the slow growth in emissions from waste and agriculture. Net non-energy emissions from the advanced economies are reduced because of the considerable expansion in the carbon sink provided by forestry. The expansion of forestry has been cutting net non-energy emissions to less than half of gross emissions. Net non-energy emissions in the advanced economies are likely to be 10% of total GHG emissions by 2010, but this proportion is increasing because the rate of forestry growth is lessening, reducing the absolute level of carbon absorption
