Biochar

Biochar: the pathway Biochar is what you get when you cook biomass — crop residues, forestry waste, sewage sludge — in a low-oxygen environment at several hundred degrees Celsius. The carbon that the plant pulled out of the atmosphere ends up locked in a stable, ring-structured solid that resists microbial decay for centuries when applied to soil or used as a filler in concrete and asphalt. It is, by volume, the largest delivered carbon dioxide removal (CDR) pathway today: biochar accounts for the majority of tonnes actually issued on registries like Puro.earth and the European Biochar Certificate (EBC), even as direct air capture attracts more capital per tonne announced. ...

First US ocean CDR bill introduced, WHOI’s alkalinity trial shows no marine harm, forward carbon credit deals hit $5.8B, and Sweden freezes a BECCS project. Your daily carbon removal roundup.

Biochar delivers over 90% of all commercially traded permanent CDR credits. The $838M market is growing fast — here’s why it matters.

Tree planting is great, but it’s not enough. Here’s why the carbon removal portfolio needs to be much, much wider.
