Fund reforestation from the surplus of a profitable consumer product, locked so it can't be diverted

Mechanism

Take a high-frequency consumer behaviour that already throws off revenue — here, web search funded by ad clicks — operate it at a profit, and ring-fence the operating surplus to fund reforestation, paying established local NGOs and restoration partners rather than planting directly. Publish partner names and amounts on a regular cadence. Make the commitment hard to reverse via a mission-locked ownership structure, so a future owner or a bad quarter cannot quietly redirect the money.

Where it fits

This targets funding durability: it converts routine consumer spending into a steady, multi-year flow to restoration partners, decoupled from grant and aid cycles. It is a financing mechanism — a complement to enforcement, supply-chain, and coordination approaches, not a replacement.

Operating profile

• Funding scales with usage and ad economics; at scale it can move millions per month to partners.
• It leverages existing local planting capacity instead of building a planting operation from scratch.
• The governance lock is what makes the pledge credible over the long horizon restoration requires — without it, a planting commitment is as cuttable as any CSR line item.

Honest limits

• Revenue fluctuates with ad-click rates and upstream platform dependencies, so the flow is steady-ish, not guaranteed.
• It funds planting, not prevention: it does not stop illegal clearing, and counting trees planted elsewhere against forest lost is an offset claim, not a halt.
• Because it pays partners, verification is delegated: survival, additionality, and biodiversity value depend on partner quality and remain largely self-reported — a central weakness this mechanism does not resolve.

Evidence

Ecosia — the "search engine that plants trees" — is the most-documented implementation and is attached as a case study.
