"Chevron, Occidental Petroleum and the Australian mining giant BHP this year have invested in Carbon Engineering, a small Canadian company that claims to be on the verge of a breakthrough in solving a critical climate change puzzle: removing carbon already in the atmosphere.Blamed for Climate Change, Oil Companies Invest in Carbon Removal | NYT
At its pilot project in Squamish, an old lumber town about 30 miles north of Vancouver, the company is using an enormous fan to suck large amounts of air into a scrubbing vessel designed to extract carbon dioxide. The gas can then be buried or converted into a clean-burning — though expensive — synthetic fuel.

With electric cars and solar and wind power becoming increasingly affordable, executives acknowledge that business as usual could put their companies at risk."
