Biochar Cuts Agricultural Emissions by Up to 83%. A 78-Study Meta-Analysis Confirms the Swiss Army Knife of Climate Solutions.
Every few months, another study adds a line to biochar’s already impressive resume. But this one is different — it’s not a single experiment, it’s the whole picture. A new meta-analysis published in Carbon Research, led by Mbezele Junior Yannick Ngaba, synthesized 78 peer-reviewed studies from across the globe to quantify biochar’s impact on agricultural greenhouse gas emissions. The headline numbers: CO₂ emissions: reduced by 24% Methane (CH₄): reduced by up to 36% Nitrous oxide (N₂O): reduced by up to 39% And at high application rates (40 tonnes per hectare), the global warming potential reduction reached 83% on a 100-year timescale. ...
