The oceans absorb billions of tons of carbon dioxide from the atmosphere. The world would be a lot warmer without them.
  • The carbon dioxide removal company Equatic has begun designing its largest plant yet.
  • The project will be North America's first commercial-scale CDR plant, scheduled to go online by 2027.
  • Many questions remain over CDR's environmental and economic impact.

The oceans are our planet's largest carbon sink, naturally absorbing about 25% of the carbon dioxide that humans emit. Carbon dioxide removal (CDR) companies like Equatic are trying to harness that natural process to absorb even more.
