Mitigation of greenhouse gas emissions often reduces co-emitted air pollutants, with advantages for human health. Avoided mortality from air pollution, a co-benefit of CO2 abatement, is estimated under global climate change mitigation scenarios to be in the range of US$50–US$380 per tonne of CO2. This exceeds the projected mitigation costs for 2030 and 2050, and is within the lower range of costs expected in 2100.
