FlickrThe U.S. is far behind in developing the tech and nature-based methods it will need to mop up unavoidable emissions in the next few decades, according to a new report on carbon removal from the Rhodium Group think tank. Dedicated projects for carbon removal, mostly via planting trees, amount to about 5 million metric tons today. Under current policies, including tax credits in the Inflation Reduction Act, the Rhodium report projects that figure to grow to 50 million tons by 2035, and expand to include a much wider range of technologies including direct air capture, biomass burial, ocean fertilization, and enhanced rock weathering. But depending on which scenario you trust, around 20% of U.S. emissions in 2050 will need to be “netted out” with carbon removal, which amounts to one billion tons, or 20 times more than the forecast. “If the U.S. wants to continue its momentum on carbon removal, a lot more needs to happen, and soon, on a lot of different fronts,” said John Larsen, a co-author of the report. That includes more public investment in early-stage R&D on innovative carbon removal strategies, more research focused on measuring and monitoring real emissions data; more federally-funded “hubs” for first-of-a-kind projects to be built with special care, and more inducements for individuals and companies to purchase carbon removal credits. All of that could add up to $100 billion a year by 2050, Larsen said — about the current budget of the U.S. Department of Agriculture. The easiest way to pay for it would be a national price on carbon, although Larsen said he has lost confidence in the political likelihood of that policy in the United States. Short of that, the best way to save taxpayers money on carbon removal in the future is to spend more on carbon avoidance now. |
