Abstract: This paper presents economic benefit estimates of air quality improvements in Europe that occur as a side effect of GHG emission reductions. We consider two climate policy scenarios from two representative concentration pathways (RCPs), in which radiative forcing levels are reached in 2100. The policy tool is a global uniform tax on all GHG emissions in the integrated assessment model WITCH. The resulting consumption patterns of fossil fuels are used to estimate the physical impacts and the economic benefits of pollution reductions on human health and on key assets by implementing the most advanced version of the ExternE methodology with its impact pathway analysis. The mitigation scenario compatible with $$+2\,^{\circ }\hbox {C}$$ + 2 ∘ C (RCP 2.6) reduces total pollution costs in Europe by 84 %. Discounted cumulative ancillary benefits are equal to about €1.7 trillion between 2015 and 2100, or €17 per abated tonne of $$\hbox {CO}_{2}$$ CO 2 in Europe. The less strict climate policy scenario (RCP 4.5) generates benefits equal to €15.5 per abated tonne of $$\hbox {CO}_{2}$$ CO 2 . Without discounting, the ancillary benefits are equal to €46 (RCP 2.6) and €51 (RCP 4.5) per tonne of $$\hbox {CO}_{2}$$ CO 2 abated. For both scenarios, the local benefits per tonne of $$\hbox {CO}_{2}$$ CO 2 decline over time and vary significantly across countries. Copyright Springer Science+Business Media Dordrecht 2015
