-Carbon dioxide and methane emissions important for the global climate impact. -Less impact through energy efficiency (CO2) and better control of CH4-emssions. -Rapid increase in emission of pollutants. -Rapid increase in regional pollution. -Future increase gives regional impact on climate. -The regional impact can be reduced by removing pollutant like SO2, NO2, CO and hydrocarbons from the emissions. Conclusions China and several other countries in the region are characterised by a fast growing economy with increasing demand for energy and rapid increase in the emission of greenhouse gases and other pollutants. It is expected that the increase in emission of pollutants will continue with increasing economic development in the industrial sector, with the increases in motor vehicles and in air traffic unless strong measures are taken to reduce emissions. Future regional emissions could lead to, not only rapid increases in local and regional pollution, but also strong regional impact on climate through regional perturbation of sulphate particles and ozone. The regional climate impact can be limited if appropriate measures are taken to remove pollutants like SO2, NOx, CO2, and hydrocarbons from the emissions. Such measures will also reduce local and regional pollution. The global impact is strongly linked to the use of energy (coal) end the emission of CO2. Emission of methane is probably also an important contributor, and there are potentials for significant reductions of the climate impact from methane.
