Like many African cities, Lomé, the capital of Togo, has a pollution problem.

Its ambient (outdoor) air pollution levels exceed World Health Organization (WHO) guidelines for human health protection. Air pollution is the world’s largest environmental health risk. In Togo, a country of 8 million people, it contributes to 6,700 premature deaths per year.

Air pollutant emissions and emissions that contribute to climate change come largely from the same sources. So it makes sense to tackle the two issues together. The question is, how?

“We evaluated the impact that implementing ten mitigation measures in Togo would have on reducing air pollutants and climate pollutants simultaneously.”

— Chris Malley, SEI Senior Research Fellow

The integrated assessment identified measures which could significantly reduce both greenhouse gas emissions and local air pollution. This work shows us that it is possible to increase motivation for more ambitious climate action by identifying and quantifying the additional benefits, such as improving citizen’s health, that action will achieve.
