Tentree has built legitimate supply chain transparency and planted 110+ million verified trees, but emissions reduction lags offsetting. Scope 3 is quantified at 6,736 tCO2e (99.65% of total), yet supply chain decarbonization remains early-stage. Heavy reliance on tree-planting and offsets to claim climate neutrality obscures weak absolute emission cuts.
