C40 Promoting Climate Action for Healthier City Living
With urban areas expected to accommodate two thirds of the world's population by 2050, radical action is needed to change the way we run our cities say C40, a network of cities committed to climate action.
The new research findings, produced in collaboration with CERC, BuroHappold and LSHTM, show that if C40's 96 member cities take the ambitious actions outlined in the report they could see an 87% reduction in greenhouse gas emissions, a 49% reduction in PM2.5 levels, 223,000 premature deaths averted and up to $583 billion in economic benefit.
Within the city environment, buildings and road traffic together contribute more than 75% of greenhouse gas emissions and 50% of PM2.5 concentrations. The report details ways to target the biggest polluters and thus tackle climate change and urban air pollution together, using specific case studies of actions taken in cities around the world.
