How trees could help to save the climate

ethz.ch – July 4, 2019

Around 0.9 billion hectares of land worldwide would be suitable for reforestation, which could ultimately capture two thirds of human-​made carbon emissions.

The Crowther Lab of ETH Zurich has published a study in the journal Science that shows this can be a powerful tool for drawing carbon from the atmosphere.

The Crowther Lab at ETH Zurich investigates nature-​based solutions to climate change. In their latest study the researchers showed for the first time where in the world new trees could grow and how much carbon they would store.

Study lead author and postdoc at the Crowther Lab Jean-​François Bastin explains: “One aspect was of particular importance to us as we did the calculations: we excluded cities or agricultural areas from the total restoration potential as these areas are needed for human life.”
