Cameroon’s forests collectively store over 7.1 billion tonnes of carbon, equivalent to 26 billion tonnes of CO₂—a global climate stabilizer. Yet Cameroon receives little to no return from international carbon markets. This area has been geo-tagged to symbolize a shift: from passive carbon sink to strategic carbon sovereign. Our POME-to-Biogas-Fertilizer project is proof that local innovation can secure global climate benefits. Through carbon retention and regenerative practices, this zone should be recognized and rewarded not just for its emissions reductions, but for the invisible service it renders to humanity by keeping carbon grounded. This is not charity—it’s a climate debt owed to Cameroon.
