摘要
The combustion of fossil fuels emits a range of damaging pollutants, the emissions of which are reduced if fossil fuel use is reduced in order to achieve CO2 abatement. These reductions are termed the secondary benefits of such abatement. The paper reviews estimates of the size of these benefits. Although the estimates are few and uncertain, they uniformly suggest that the secondary benefits are of the same order of magnitude as the gross costs of medium to high levels of CO2 abatement, and are substantially larger than the (equally uncertain) estimates of the primary benefits of CO2 abatement, except where these benefits derive from consideration of damages from unabated global warming in the very long term. The paper concludes that the existence of significant secondary benefits greatly reinforces the economic case for an aggressive policy of CO2 abatement.
