Climate action could prevent one million air pollution-related deaths

New research from C40 Cities, the Global Covenant of Mayors for Climate & Energy and the New Climate Institute shows that climate action, such as doubling bus network coverage and frequency in cities, could prevent the premature deaths of over one million people per year from air pollution and traffic accidents.


Cars cause a lot of air pollution

The report, titled “Climate Opportunity: More Jobs; Better Health; Liveable Cities,” also argues that climate action, which include energy efficiency retrofits in buildings, enhanced bus networks and renewable energy initiatives, could generate 13.7 million jobs in cities and save 40 billion hours of commuters’ time plus billions of dollars in reduced household expenses each year.

Report authors argue that climate policies lead to positive public health and economic outcomes across countries and regions.

Some of the main findings of the study include:

  • Investments in residential energy efficiency retrofits could result in a net creation of 5.4 million jobs in cities across the globe. Such investments would also result in significant household savings, as well as emissions reductions.
  • Improved public transport could prevent the premature deaths of nearly one million people per year from air pollution and traffic fatalities worldwide. Improved transport networks could also save 40 billion hours of commuters’ time every year by 2030, while achieving important emissions reductions.
  • District-scale renewable energy for heating and cooling in buildings could prevent a further 300,000 premature deaths per year by 2030. Renewable energy could contribute to significant emissions reductions and create approximately 8.3 million jobs.
  • Climate action policies can have proportionally greater outcomes for lower income groups in developing cities, where populations have the most to gain from the introduction of new technologies.

“Cities account for 73 per cent of global greenhouse gas emissions, making large-scale climate action in urban areas an urgent focus of efforts to meet the highest goals of the Paris Agreement,” said Thomas Day, Partner at NewClimate Institute, who led the research.

“While cities are already leading the way in emissions reductions by cutting energy usage in their buildings, transport systems, and industries, Climate Opportunity will give policymakers a compelling justification for climate action by illustrating the deep connection between climate and other urban priorities like public health, poverty alleviation and economic growth.”

The World Health Organisation reports that ambient air pollution alone caused some 4.2 million deaths in 2016 and the transport sector represents the fastest growing source of fossil-fuel CO2 emissions, the largest contributor to climate change.

“The Climate Opportunity research sends a powerful message that city-level climate action leads to more than addressing an environmental issue; it also has societal benefits. Well-designed measures will mitigate climate change and reduce air pollution, thereby also tackling this public health emergency,” said Martina Otto, Head of UN Environment’s Cities Unit. “Not only can cities prevent unnecessary deaths through climate action, but they also have the opportunity to stimulate economic growth, help alleviate poverty and improve the liveability of our cities.”

Launching at the same time as the research, a new online dashboard hosted on the Global Covenant of Mayors’ website allows cities to use data from the Climate Opportunity report to see how specific climate actions—such as the improvement of transport links, retrofitting buildings, or implementing renewable energy projects—can positively affect their city in the areas of job creation, reducing emissions and increasing savings.
