Negative-emissions technologies - that remove carbon dioxide from the air and in some cases, even turn it into something new - are powerful tools in the fight against climate change. In our latest Knowledge article we look at some of the most innovative approaches.
There would be no life on Earth without CO2 - no plants, animals or humans. Despite only being naturally present in the air in very low concentrations, CO2 has an enormous impact on our planet's climate. As anthropogenic (man-made) CO2 emissions rise, however, that natural balance is being disturbed and the Earth is warming up faster than ever before...
In the fight against climate change it is therefore crucial that we reduce CO2 emissions and go one step further to remove some of that already-emitted CO2 from the air. Innovators all over the world are working on ways to do this - using giant air filters, re-creating photosynthesis with artificial leaves, and in some cases even capturing that CO2 and turning it into something new.
In our new Knowledge article - CO2: Climate Killer or Valuable Resource? - RESET takes a look at some of the most interesting developments.
