Health co-benefits of climate action

摘要

The Paris Agreement was a major political step towards reducing the risks of climate change; however, even if the agreed reductions in greenhouse gas emissions are fully implemented, the global average temperature will still have increased by about 3°C above preindustrial levels by the end of the century.1 Deeper cuts are needed for the achievement of the long-term goal of keeping the increase to well below 2°C. An obvious rationale for action is the imperative to reduce the risks to health from climate change, but in an era when powerful interests seek to cast doubt on climate change science,2 major ancillary near-term benefits (co-benefits) of climate action provide added justification for policies to cut greenhouse gas emissions. Health co-benefits can arise through several pathways, including through reduced air pollution, increased physical activity, and dietary change.3.
