ABSTRACT
This chapter gives an overview of the main sources of man-made greenhouse gas emissions, the policies used to reduce these emissions and how these policies are linked to co-benefits and conflicts.
Many of the co-benefits of climate policy are linked to a reduction in the use of fossil fuels, which produce 65 per cent of man-made greenhouse gases. The main source, of course, is carbon dioxide from burning fossil fuels for heat, power and transport, with smaller contributions from nitrous oxide produced during fuel combustion and methane emitted during coal mining and oil and gas production.
