Speeding up progress on reducing carbon emissions would save millions of lives, mostly in metropolitan areas of Africa and Asia.

Speeding up progress on reducing carbon emissions would save millions of lives, mostly in metropolitan areas of Africa and Asia.

To keep global warming below 1.5 degrees Celsius, the world would need to cut the majority of fossil-fuel related carbon emissions this century – and because this would also reduce air pollution locally, it would prevent 150 million premature deaths, according to a paper published in Nature Climate Change.

The researchers found that reducing this century’s expected carbon dioxide emissions by 180 gigatonnes – the amount needed to meet the 1.5 degree target, or keep global warming at 2 degrees without negative emissions– would mean moving to a largely renewables-sourced energy system.

Making this shift sooner rather than later would save an estimated 90 million lives by 2100 due to reduced exposure to fine particles, according to the study. Another 60 million deaths could be prevented because of reduced ozone levels.
