Three reports were launched on 22 July by experts convened by the UN, showing how greater impact can be achieved by breaking down silos and tackling the climate change and sustainable development crises together.
With the majority of the global population residing in cities, which also account for the majority of GHG emissions, there is great potential to improve public health through climate action with high-impact co-benefits, according to the expert report on Linking Climate and Health Action in Cities. Reducing air pollution by replacing fossil fuels with clean energy could prevent up to 1.2 million premature deaths annually by 2040, with up to 4.7 million additional lives saved if measures against black carbon and methane are adopted. A shift to plant-based diets could prevent 10–11 million premature deaths yearly. Infrastructure promoting walking and cycling can cut emissions, improve cardiovascular health, and reduce mortality, and increasing urban tree cover to 30% could prevent over 2,600 heat-related deaths each summer in Europe alone. Financial and technical support at the national and international levels is vital to enables cities—especially in the Global South—to implement such synergistic strategies.
