Capital Formation and Risk SharingPHILANTHROPIC PURCHASE VEHICLES
Lever last updated: 10 September 2026
A charitable fund that pools donations to buy and retire verified removals.
Cost
Very low to Medium
The vehicle spends donated money on purchases and administration. A multi-year portfolio pays for due diligence, contracting, verification, registry use and reporting. Total cost is more related to the chosen volume and removal prices.
Complexity
Low to Medium
An established charity can add a purchase programme, while a new or cross-border vehicle must establish charitable authority, CDR eligibility, supplier checks, contracts, payment records, verification, retirement, claims and tax reporting.
Timeline
Very short to Short
An established charity can sign its first purchase within months. Forming a new vehicle, raising donations and building selection, contracting and retirement systems may take one to two years.

Overview
A philanthropic purchase vehicle is a charity or charitable fund that pools donations and uses them to buy verified CDR. It may pay suppliers before delivery and retires each delivered unit, recording it as used so it cannot be sold or claimed again. Donors may receive a tax benefit where local law permits, but they do not receive removal units to offset their own emissions. A fund that resells units instead provides revolving finance to suppliers, so resale and retirement pools must remain separate. Corporate procurement, grants and public matching are different levers.
Key Considerations
Trustees need to decide which removal methods and storage periods qualify, how much delivery risk donors will bear and how much of each donation may cover administration. Contracts should specify delivery dates, verification, ownership, replacement or refunds after non-delivery, responsibility after reversal and social and environmental safeguards. The vehicle must distinguish units it retires from those it resells, because the original donor and a later buyer cannot both claim the same removal. Reports should reconcile donations, fees, contracts, cash paid, tonnes delivered, resale and retirement. Tax benefits, donor communications and foreign payments must follow applicable charity and tax law.
Opportunities
Pooling lets individuals and smaller organisations support removals without evaluating suppliers or negotiating contracts alone. Specialist staff can spread donations across projects, prepay suppliers and publish how they were assessed. Charitable money may tolerate technical risk or long delivery periods that ordinary buyers reject, giving newer methods an opportunity to build operating evidence. Retiring units without an offset claim treats removal as a public benefit. A revolving fund can reuse sale proceeds, but it finances suppliers rather than retiring removals for the original donors.
Risks
Poor screening can waste donations on tonnes that arrive late, cannot be verified or do not remain stored. Donors may wrongly assume that a tax receipt conveys an offset claim. Mixing retirement and resale accounts can create duplicate claims. Prepayment exposes the charity to supplier failure, while fundraising and diligence leave less money for purchases. A broad climate fund may also report conservation, avoided emissions or research as though every contribution delivered CDR.
Monitoring and Evaluation
Evaluation should reconcile donations and fees with contracts, cash paid, delivered tonnes, resale, retirement and replacement. Costs, delays, failures, reversals, safeguard breaches and repeat giving show whether the vehicle is buying credible removals while retaining donor support. Poor delivery or conflicting claims should change supplier limits, contract terms or separation between funds.
Stakeholder Engagement
Engagement should establish how much delivery risk donors will accept, which suppliers can offer credible tonnes and what claims follow retirement or resale. Trustees need evidence from CDR specialists, standards bodies, verifiers, registries and tax advisers, while affected communities and civil society help identify safeguards and public reporting needed to sustain trust.
Governance Level
Charities and foundations can accept restricted donations, choose suppliers, sign purchase contracts and retire delivered units. Their boards remain responsible for charitable purpose, financial risk, tax compliance and climate claims even when another provider administers the fund. Companies may donate and governments may recognise tax relief, but neither role makes industry or government the implementing actor. The lever is pulled by the philanthropic body that controls the donated funds, supplier contracts and final use of each removal unit.
Implementation Strategies
Trustees should define the charitable purpose, eligible removals, donor claim, administrative allowance, risk limits and whether each pool retires or resells units.
Published selection criteria should cover net removal, storage, verification, safeguards, price and delivery readiness.
Contracts should use staged payments, independent evidence and replacement or refund rights, supported by separate records for ownership, resale and retirement.
Annual reconciliation of donations, spending and delivered tonnes should guide supplier limits and future contract terms.
Case Studies

Terraset
Terraset is a United States charity that uses donations to pay for CDR and other climate outcomes before delivery. Its 2025 annual report says it had raised over USD 10 million, supported 25 projects and reported 21,000 tonnes of CO₂ removed. It also launched a revolving carbon-removal fund in May 2025, purchasing over USD 1 million across 13 deals and reselling more than USD 200,000 to four buyers. The vehicle is operational, but its portfolio also includes methane and refrigerant projects, and the report does not fully reconcile CDR purchases, verified deliveries, retirements and resales. The lesson is to separate accounts and claims.

Milkywire Climate Transformation Fund
Milkywire established the Climate Transformation Fund with Klarna in 2021 to turn corporate contributions into grants and purchases across carbon removal, emissions reduction and nature. In June 2025, it announced 15 CDR purchases and three grants after 280 durable-removal suppliers applied; donation-funded purchases run through the WRLD Foundation. The vehicle is operational, but its wider USD 17 million and nearly 70-project totals combine different climate activities, while published figures do not yet show how many purchased CDR tonnes were delivered and retired. The lesson is to report CDR contracts and outcomes separately from the wider fund.
