Mossy Earth is a small, bootstrapped rewilding platform with negligible operational emissions and a core mission delivering genuine biodiversity restoration across 500+ hectares. The critical weakness: no formal corporate emissions accounting or science-based reduction targets, though operational scale makes this less material than transparency and accountability gaps—no board governance, impact compensation links, or mission-lock structures.
Mossy Earth scores 63/100 (Leading practice) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Mossy Earth joint 6th of 847 companies scored, and it is the only Rewilding / Ecosystem Restoration company scored so far.
Mossy Earth stands alone in this category.
