A tiny Swiss company that thinks it can help stop climate change

At the moment, global CO₂ emissions are about 37 billion metric tons per year, and we’re on track to raise temperatures by 3 degrees Celsius by 2100. To have a shot at maintaining a climate suitable for humans, the world’s nations most likely have to reduce CO₂ emissions drastically from the current level — to perhaps 15 billion or 20 billion metric tons per year by 2030; then, through some kind of unprecedented political and industrial effort, we need to bring carbon emissions to zero by around 2050. Direct air capture could even lessen the impacts of the Haber-Bosch processes for making fertilizer; by some estimates, that industry now accounts for 3 percent of all CO₂ emissions.
