Voluntary and Normative DriversCOLLECTIVE PURCHASE PLEDGES/MOUS
Lever last updated: 14 September 2026
A shared commitment by several buyers to purchase a stated volume of removals by a date.
Cost
Very low to High
A non-binding pledge costs members staff time, legal advice and reporting. A binding purchase commitment also obliges them to pay for removals, potentially dominating a large coalition's annual expenditure. An announcement's headline value is not expenditure; payments through a coordinator should be counted once.
Complexity
Low to Medium
A common pledge uses established budget and legal approvals. Joint procurement adds supplier assessment, payment administration, rules for distributing credits and contractual remedies when a member withdraws or a supplier fails.
Timeline
Very short to Short
Buyers with approved budgets can place initial coordinated orders within a year. New coalitions may need one to two years to obtain approvals, select suppliers and conclude purchases; an announcement alone is not the endpoint.

Overview
A collective purchase pledge is a shared commitment by several buyers to obtain a stated volume or value of carbon removal by an agreed date. Public bodies, companies or foundations coordinate their intentions, budget approvals and approach to suppliers. They may record the agreement in a memorandum of understanding, which sets out their commitments and working arrangements. Its provisions can be binding or non-binding, so the document's name does not determine its strength. Members normally approve and pay for their own purchases; any authority for a coordinator to contract on their behalf must be explicit. The combined pledge identifies prospective customers, while enforceable purchasing terms provide stronger evidence of future revenue.
Key Considerations
Participants should specify quantities or budgets, deadlines, removal-quality requirements and which provisions are legally binding. They must decide whether members contract independently, a coordinator arranges purchases, or an intermediary pools funds and buys on their behalf. Agreements need rules for withdrawal, supplier selection, the distribution of delivered units and reporting. Common criteria can require credible carbon accounting, environmental protection and community engagement. Each buyer's finance and legal teams should approve its commitment, including compliance with public procurement rules where relevant. Existing member contracts should be identified so the same purchase is not repeatedly announced as new demand.
Opportunities
A shared quantity and deadline can give buyers a reason to bring forward budget decisions and suppliers a clearer view of prospective business. Smaller buyers can contribute to an order large enough to interest a developer, while members that intend to use the same requirements can coordinate their approach to the market. Earlier or larger contracts can support commercial learning when they fund emerging methods. Buyers gain a public commitment they can be held to, and suppliers gain stronger financing evidence as those commitments become enforceable orders. A large headline pledge alone demonstrates neither secured revenue nor a price reduction.
Risks
Members may withdraw or delay purchases, leaving headline demand larger than the underlying budget. Suppliers can overinvest if non-binding intentions are presented as firm revenue. Divergent quality preferences and legal requirements can slow collective decisions, while concentrated portfolios create delivery exposure. Strong buyer bargaining power may also push prices below sustainable costs or exclude smaller suppliers. Clear commitment status, conversion milestones and transparent progress are necessary to prevent the pledge becoming a reputational exercise.
Monitoring and Evaluation
The coordinator should report pledged, budgeted, contracted, paid, delivered and retired volumes separately, with progress for individual members where possible. Retirement means recording that a unit has been used and cannot be claimed again. Conversion rates, withdrawals and missed milestones reveal where commitments are failing to become purchases. Evaluation should test whether the collective process produced additional or earlier contracts and whether smaller suppliers could participate, then use those findings to change membership rules, purchasing schedules or subsequent rounds.
Stakeholder Engagement
The participating buyers' finance teams should approve budgets, procurement teams should specify their needs and legal teams should establish the commitments each organisation can make. Suppliers can test delivery schedules and quality requirements through an open selection process. A coordinator should report progress and administer any agreed distribution of units, with independent specialists assessing project evidence. Public buyers must confirm that the arrangement fits their procurement powers.
Governance Levels
Public bodies, companies and foundations can make joint commitments within their own budgets and purchasing powers. An international or supranational institution qualifies when it undertakes or jointly administers those commitments, rather than merely endorsing them. Corporate coalitions can organise the same activity across countries.
Implementation Strategies
Anchor members should secure budget approval or publish the remaining approval milestones. The coalition should specify its volume or spending goal, delivery dates and quality requirements before announcing a combined commitment.
Members should state which provisions are binding and decide who contracts, pays and receives the delivered units. They should agree withdrawal rules, the coordinator's authority and the consequences if commitments are not honoured.
The coordinator should invite supplier proposals using published selection criteria and proportionate technical checks. Buyers should test delivery schedules, environmental and social requirements, concentration in a few projects and routes for smaller or emerging providers to participate.
The coalition should publish progress from intention to contract and delivery, with deadlines for resolving unconverted pledges. Members can share purchasing lessons and adjust future rounds when budgets or projects fall behind.
Case Studies
Airbus and airline expressions of interest
Airbus, the aircraft manufacturer, brought major airlines together in July 2022 through letters of intent to explore carbon-removal purchases. The airlines agreed to negotiate possible purchases of verified direct-air-capture removals. Separately, Airbus had arranged to pre-purchase 400,000 tonnes from 1PointFive, a carbon-capture developer, providing a route through which airlines could obtain credits. In October 2023, Airbus announced an easyJet purchase agreement, with credits scheduled for 2026 to 2029. The sequence illustrates a coordinator moving interested buyers towards contracts around a shared source of supply. The airline letters did not themselves commit the group to purchase Airbus's entire 400,000-tonne allocation, and the announcements establish commitments rather than completed delivery.
First Movers Coalition removal commitments
The First Movers Coalition is a corporate purchasing initiative convened by the World Economic Forum and the US government to encourage early demand for emerging climate technologies. At its May 2022 CDR launch, AES, Mitsui O.S.K. Lines and Swiss Re each committed to 50,000 tonnes or USD 25 million of carbon removal by 2030, with storage lasting more than 1,000 years. Members arrange their purchases, supported by specialist implementation partners; the coalition does not hold a corresponding prepaid purchasing fund. The quantified threshold gives companies a procurement objective and suppliers a visible group of prospective customers. Its contribution to finance depends on members translating those public commitments into contracts with acceptable delivery and payment terms.
