Scientists have come up with a system that removes CO2 from the air

Based on the results of the work, the new program could reduce global temperatures by 2100, provided that it

will be launched soon. 

The study evaluates how government funding will lead to the deployment of a DAC capture system that will remove CO2 from the atmosphere.

DAC will cost significantly more than many traditional mitigation measures, but costs may fall as firms gain experience with the technology.

Co-author David G.Victor, a professor of industrial innovation at the School of Global Policy and Strategy at the University of California, San Diego, added that the concentration of CO2 in the atmosphere is so high that we need to find ways not only to reduce it, but also to eliminate emissions that were previously made. 

The authors concluded that if the programdirect air capture of CO2 started operating in 2025 and received an investment of 1.2-1.9% of global GDP annually, it could remove about 2.2-2.3 gigatons of CO2 by 2050. 

According to the authors, DAC has characteristics that may be of interest to policymakers who support the green movement and combat climate change.
