Abstract

Integrating Greenhouse Gas Mitigation Strategies into Air Pollution Regulations Greenhouse gases and local air pollution exhibit a significant degree of interaction. Since air pollution is an important public health issue, and sources of these emissions are often the same as greenhouse gases, policies aiming to mitigate one of these environmental problems will potentially have large effects on the other. From an economic efficiency point of view, it is important to take into account these co-effects when deciding on appropriate policy measures in response to these problems, and policies neglecting these co-effects may be sub-optimal. The interrelations between policies for GHG mitigation and policies for local air pollution can be investigated from two different perspectives: Climate change window: policies primarily aiming at the mitigation of GHG not only reduce emissions of GHG, but also reduce emissions of local air pollutants; Air pollution window: policies primarily aiming at the mitigation of local air pollution not only reduce emissions of air pollutants, but also reduce emissions of GHG; In this report, the GHG reduction effects of policies for local air pollution and the potential results of various alternative policy options are examined from the air pollution window. This study provides a basis for developing an integrated strategy tackling climate change and air pollution.
