Every square meter of forest absorbs enough CO2 to offset about 1 Watt of carbon fuel use. The average US inhabitant uses about 10kW on average. About half of US energy use is from fossil sources and the population is about 300 million. So we'd need 150 million new hectares of forest, growing forested land from 1/3 of the country to 1/2. Which is honestly a lot more doable sounding than I'd thought it would be before running the numbers. EDIT: Eventually the forest will climax and start emitting as much CO2 as it absorbs but that's a lot of time to solve the problem at a more fundamental level. |
