Group 1 - Boeing has signed a deal with startup Charm Industrial to remove 100,000 metric tons of carbon from the atmosphere [1] - Charm collects agricultural and forestry waste to produce "bio-oil," which is injected underground for carbon sequestration [1] - The aviation industry has made little progress in reducing carbon emissions, leading to a search for alternatives like carbon removal [2] Group 2 - By 2050, the aviation industry may need to spend at least $60 billion on carbon offsets to achieve net zero emissions [2] - Charm can also produce biochar, which can enhance soil productivity, although these efforts are still developing [3] - Two years ago, Charm sold 112,000 carbon removal credits for $53 million, aiming to reduce costs to about $50 per metric ton [3]
