In order to reach global net-zero emissions by 2050, we must remove CO2 from the atmosphere as well as prevent further emissions.(CDR) can be accomplished naturally – through forests, soil sequestration, or mineralization – and technologically. In fact, we will need both CDR methods to get to net-zero. So what technologies exist that remove carbon from the atmosphere? What are their respective costs, how do they compare, and which are already on the market? Watch to find out.
