CDR growth stalls as Trump policies and global conflicts slow investment, scientists warn

Scientists at a Milan conference reported that carbon dioxide removal (CDR) is stagnating, with only 2 million tonnes removed in 2025 against over 40 billion tonnes of human emissions. Political shifts under the Trump administration and ongoing wars have reduced interest and funding for CDR research and deployment, according to Massimo Tavoni of the Polytechnic University of Milan. Natural methods like reforestation account for 99.9% of current removals, but their growth is slowing due to land competition. Engineered solutions like direct air capture remain negligible and costly, often above $200 per tonne. Researchers argue that scaling CDR requires government purchases as a public good, not just corporate voluntary carbon credit demand. The report underscores that CDR cannot substitute for deep emission cuts. Without policy support and billions in investment, the sector will fall far short of the levels needed to meet climate targets. The coming years are critical for deciding whether CDR scales or remains a niche effort.

2 million tonnes removed vs 40 billion emitted. That ratio is brutal. CDR is basically a rounding error right now, and the article makes it clear that political headwinds are making it worse.

Yeah, and 99.9% of that is just planting trees. The engineered stuff is vanishingly small. If we're serious about this, the cost needs to come down way below $200/tonne.

At $200+ per tonne, who actually buys that? Voluntary carbon markets won't scale it alone. The article is right that governments need to step in as buyers, but that's a tough sell politically.

The public good framing is correct but politically naive right now. In the current climate (pun intended), getting governments to fund something that doesn't show immediate results is an uphill battle.

And the article mentions competition with agricultural land for reforestation. That's a real pinch point. You can't just plant trees everywhere without affecting food production.
