Ecologist Thomas Crowther’s research inspired countless tree-planting campaigns, greenwashing, and attacks from scientists. Now he’s back with a new plan for nature restoration.
Mass timber is a good option for making them better forms of carbon sequestration but that's going to be a relatively minor contribution to the amount we'd need to draw down to stay in the atmosphere's good graces.
I wonder how much CO2 the world could sink in a few decades if the rest of the developing world went on a Chinese-style construction boom but with mass timber instead of concrete. 🤔
Based on this life cycle assessment, a single 12-story, roughly 8,000 sq meter mass timber building would sequester nearly 2 tons of CO2, and per the Fed (ymmv), China's been producing roughly 50 MM sq m/month, which works out to ~139 kilotons/year.
Those 4- and 5-over-1s are mostly petroleum

Oh, that's nothing. 😅
Whoops, I misread. It's 1.84 kilotons per building, so 154 megatons per year, plus roughly the same in mitigated emissions. Exponents amirite
Out of like 30 gigatons annually so still nothing 😭
