DAC in particular is in its infancy, with only 19 active plants capturing about 10,000 tons of CO2 annually (equivalent to the tailpipe emissions of about 2,000 cars).

We see three main areas of innovation where current and future startups can focus to make DAC a robust and cost-effective part of the carbon removal portfolio.
