Far larger facilities are in the works as well. Carbon Engineering, based in Squamish, British Columbia, plans to start construction this year on a plant in the US Southwest with the capacity to remove1 million tonsof carbon dioxide a year. With various partners, it’s also begun engineering or design work on plants inScotlandandNorwaythat would capture 500,000 to 1 million tons per year.
