In order to reach global net-zero emissions by 2050, we must remove CO2 from the atmosphere as well as prevent further emissions. Carbon Dioxide Removal (CDR) can be accomplished naturally -- through forests, soil sequestration, or mineralization -- and technologically. In fact, we will need both natural and technological CDR methods to get to net-zero. So what methods exist that remove carbon from the atmosphere? What are their respective costs, how do they compare, and which are already on the market? Series: "Sustainable California" [Science] [Show ID: 38045]
