A new breakthrough in climate-change-fighting technology may come from, of all places … Exxon?

It’s not as crazy as it sounds. Exxon and other fossil fuel companies are under pressure from lawmakers and stakeholders to publicly own up to its role in causing climate change.

Instead of, say, diversifying its portfolio in renewables, the oil giant is looking for an alternate way to decrease their footprint — one that will let them keep burning fossil fuels.

Reuters reports that scientists from ExxonMobil and the Georgia Institute of Technology have developed a method to reduce carbon emissions from chemicals manufacturing. Currently, this is done using heat, but using a new method of reverse osmosis at room temperature theoretically would reduce the industry’s annual carbon dioxide emissions by up to 45 million tons if the technology were widely adopted, according to the company.

Grist thanks its sponsors. Become one.

Now, if only they’d use all that brain power to create a time machine, go back to 50 years, and warn us about climate change when their own scientists first warned executives about it.
