The device that reverses CO2 emissions

BBC  

The device that reverses CO2 emissions Carbon Engineering Carbon Engineering is planning the world's largest direct air capture plant, in Texas, USA Cooling the planet by filtering excess carbon dioxide out of the air on an industrial scale would require a new, massive global industry – what would it need to work? When it becomes operational in September, Carbon Engineering's prototype direct air capture plant will begin scrubbing a tonne of CO2 from the air every year. "We have a climate change problem and it's caused by an excess of CO2," says Carbon Engineering chief executive Steve Oldham. "The number of things that would have to happen without direct air capture are so stretching and multiple it's highly unlikely we can meet the Paris Agreements without it," says Ajay Gambhir, senior researcher at the Imperial College Grantham Institute for Climate Change and an author of a 2019 paper on the role of DAC in climate mitigation.

What is carbon capture?

The Hindu  

Global warming is the result of certain greenhouse gases — but especially carbon dioxide — building up in the air and preventing the planet from cooling as quickly as it would without them. Although some natural processes emit these gases, their build-up to dangerous levels is entirely due to emissions from human industrial activity, including the combustion of fossil fuels …
