Investors fund conservation before results appear, and an independent verifier releases outcome payments after checking species, habitat and community benefits. Compare upfront-only, success-only and multi-metric contracts to find a structure that lets field teams start while protecting the payer.

What this model calculates: Upfront, outcome and holdback shares, plus funding risk when outcomes fall short

Water utilities, power producers, insurers and other downstream beneficiaries jointly pay for forest restoration that can reduce fire, sediment, water-quality and outage losses. Compare who benefits, who advances construction funds, and which verified milestones trigger repayment.

What this model calculates: Each beneficiary's contribution, upfront capital, repayment timing and avoided loss

Set the total nitrogen load a lake or river can safely absorb, then combine farm allowances, trading, public buybacks and transition support. Compare ways to keep water quality within the cap while distributing reduction costs and income effects fairly.

What this model calculates: The watershed cap, farm allowances, trading price, buyback cost and water quality

Avoid irreplaceable habitat first, compensate remaining impacts through on-site improvements or registered habitat, and fund at least thirty years of management. Calculate units before and after development, spatial connectivity and delivery delay so that paper gains do not pass as real gains.

What this model calculates: Habitat units before and after development, time and location adjustments, and 30-year management cost

Insure the coastal-protection and tourism value of a reef, releasing repair funds when wind exceeds a stated trigger without waiting for a full loss assessment. Change premium, trigger, payout limit and reinsurance to compare rapid recovery with basis risk.

What this model calculates: Premium, wind trigger, payout, reinsurance, basis risk and solvency

Combine debt conversion, guarantees, blue bonds and concessional finance, then split funds between conservation grants and revolving loans for ocean businesses. Calculate interest, currency and debt-service risk as well as the amount that actually reaches ecological outcomes.

What this model calculates: Guarantee, bond and loan shares, interest and FX stress, and actual disbursement

Pay farmers for annual grassland and habitat scores rather than prescribing every task. Adjust for weather and scoring differences, then combine a minimum participation payment with co-funding for improvements to test when better nature can become reliable farm income.

What this model calculates: Habitat score, minimum payment, shared improvement cost and farm income

Compare how restoring upstream forests and farms changes water quality, drought risk and local income over twenty years. Calculate no-action and intervention futures at P10, P50 and P90, then test how downstream beneficiaries fund and share value with upstream stewards.

What this model calculates: Twenty-year uncertainty bands, safety floor, total cost, beneficiary funding and Shapley allocation

Instead of dropping high-risk producers, buyers, financiers and producers share transition costs to reduce ecological pressure and supply disruption together. Change prepayment, purchase guarantees and first-loss protection to compare farm liquidity with procurement stability.

What this model calculates: Prepayment, purchase and first-loss guarantees, farm debt capacity and supply stability

Connect a developer's stormwater obligation to neighbourhood investment in rain gardens, permeable surfaces and tree canopy. Calculate retained runoff, flood and heat reduction and maintenance cost, while comparing investment in vulnerable areas and equitable green-space access.

What this model calculates: Retained runoff, flood and heat benefits, credit price, maintenance cost and equity

Fund seagrass, tidal-flat and mangrove restoration with fisheries, storm protection, tourism and local-income benefits as well as carbon. Include delivery delay, reversal under sea-level rise and double counting to compare the funding need and which beneficiaries should pay.

What this model calculates: Carbon, fisheries and protection benefits, delivery lag, reversal risk and funding gap

Coordinate neighbouring farms, not just one field, to maintain flower corridors and reduce pesticide use across a landscape. Forecast wild pollinators, pesticide pressure, yield and farm income separately, include weather variation, and compare how a shared fund divides cost and benefit.

What this model calculates: Uncertainty in pollinators, pesticides, yield and income, shared cost and farm allocation
