Not so fast. It is true that trees alone can't take us all the way to net-zero. But they can contribute, and the contribution could be non-negligible.<p>Right now for example, according to the EPA [1], the US emits about 6.6 GT CO2 equivalent per year, but the land sequesters about 0.8 GT, for a net emissions of 5.8 GT. From the 0.8 GT sequestered, about 0.7 GT come from trees. That's about 10% of the gross CO2 emissions.<p>If we can double the sequestration by trees, then we can reduce emissions by a further 10%, and that's nothing to sneeze at.<p>[1] <a href="https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks" rel="nofollow">https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas...</a>
