According to a study by the federal technology institute ETH Zurich, the reforestation and restoration of existing forest areas around the world would make it possible to sequester an additional 226 gigatonnes of carbon. This corresponds to more than six times the global CO2 emissions in 2022.
An international team of researchers, under the direction of the federal technology institute ETH Zurich, obtained this result by analysing satellite data and associating it with ground measurements. The study was published on Wednesday in the specialised journal Nature.
On a global scale, trees could absorb 328 gigatonnes of CO2 more than they currently do, without any human influence. By way of comparison, 36.8 gigatonnes of CO2 will have been emitted in the world by 2022, according to the International Energy Agency (AIE). ...
