Study: Cutting Carbon Emissions Sooner Would Likely Save Millions of Lives

There’s absolutely no positively justifiable reason that fossil fuels should still be used anywhere near their levels today, and this is another reason why.

As many as 153 million premature deaths linked to air pollution could be avoided worldwide this century if governments speed up their timetable for reducing fossil fuel emissions, a new Duke University-led study finds.

The study is the first to project the number of lives that could be saved, city by city, in 154 of the world’s largest urban areas if nations agree to reduce carbon emissions and limit global temperature rise to 1.5°C in the near future rather than postponing the biggest emissions cuts until later, as some governments have proposed.

Premature deaths would drop in cities on every inhabited continent, the study shows, with the greatest gains in saved lives occurring in Asia and Africa.

The new projections underscore the grave shortcomings of taking the lowest-cost approach to emissions reductions, which permits emissions of carbon dioxide and associated air pollutants to remain higher in the short-term in hopes they can be offset by negative emissions in the far distant future, said Drew Shindell, Nicholas Professor of Earth Sciences at Duke’s Nicholas School of the Environment.

“The lowest-cost approach only looks at how much it will cost to transform the energy sector. It ignores the human cost of more than 150 million lost lives, or the fact that slashing emissions in the near term will reduce long-term climate risk and avoid the need to rely on future carbon dioxide removal,” he said. “That’s a very risky strategy, like buying something on credit and assuming you’ll someday have a big enough income to pay it all back.”

Air pollution has also been found recently to have links to cognitive impairment in children.
