Direct Air Capture Powered by Waste Heat.

The science shows clearly that in order to avert the worst impacts of climate change and preserve a livable planet, global temperature increase needs to be limited to 1.5°C above pre-industrial levels. Currently, the Earth is already about 1.1°C warmer than it was in the late 1800s, and emissions continue to rise. To keep global warming to no more than 1.5°C  – as called for in the Paris Agreement – emissions need to be reduced by 45% by 2030 and reach net zero by 2050. CO2 must also be removed from the atmosphere. IEA calculates that between 2020 and 2050 12 Gton of CO2 must be removed to reach the 1.5°C pathway.
