Accelerating the shift from fossil fuels could save 150 million lives

March 19, 2018

Keeping global temperatures from rising more than 1.5˚C, instead of the standard 2˚C goal, could reduce deaths due to ambient air pollution.

The news: A study in Nature Climate Change analyzed the health benefits of reduced exposure to particulate matter and other pollution from fossil-fuel plants in 154 of the world’s biggest cities. Expediting the shift to clean energy could reduce levels enough to save as many as four million lives in Delhi, India, alone over the coming decades.

Bigger picture: There are many other reasons to strive for the lower temperature target, including decreasing the risks of far worse heat waves, droughts, wildfires, and more. A report in Environmental Research Letters earlier this month found that limiting temperature increases to 1.5 ˚C would also prevent sea-level rise from inundating land where some five million people live today.

But: Problem is, the world isn’t nearly on track to hit even the 2˚C target currently (see “At this rate, it’s going to take nearly 400 years to transform the energy system”).

Deep Dive

Climate change and energy

Think that your plastic is being recycled? Think again.

Plastic is cheap to make and shockingly profitable. It’s everywhere. And we’re all paying the price.

Decarbonizing your data strategy

Companies need to invest in energy-efficient infrastructure and optimize data practices, says Ian Clatworthy, director of data platform product marketing at Hitachi Vantara.

The University of California has all but dropped carbon offsets—and thinks you should, too

It uncovered systemic problems with offset markets and recommended that the public university system focus on cutting its direct emissions instead.

The power of green computing

Sustainable computing practices have the power to both infuse operational efficiencies and greatly reduce energy consumption, says Jen Huffstetler, chief product sustainability officer at Intel.
