    For comparison, a hectar of trees remove about 10 tons CO2 per year.

    A hectar is 100m to 100m.

    10 tons is ~22000 lbs

    100m is ~330 feet

    So a forest of 35 hectar would replace that machine. That’s a very small forest that you can cross in 30 minutes by foot.

    Trees don’t grow where this machine is placed, though.
