TLDR: The world holds the pledges and the budgets; the gap is execution. Corporate ESG money reaches real impact when it funds a specific project and measures the result.
The gap is execution more than intention
The shortfall is enormous and growing. The UN puts the annual Sustainable Development Goals (SDG) financing gap for developing countries at more than 4 trillion dollars a year. Pledges are plentiful, and corporate sustainability budgets are real. The difficulty sits between the pledge and the project: money that stays in a commitment letter sits idle, while money that reaches a measured project moves the number.
Guaranteed demand turns budget into projects
One mechanism already bridges the gap. An advance market commitment (AMC) converts a pledge into a purchase order: buyers commit to pay for an outcome, and that certainty finances the project that delivers it. Frontier, founded by Stripe, Alphabet, Shopify, Meta, and McKinsey, committed at least one billion dollars to permanent carbon removal, which moved corporate budgets into real plants with measured tonnes. The lesson generalises: a specific outcome, paid for in advance, pulls a project into existence.
The pledge-to-project pipeline
Impact follows a path, and the path can be engineered. A corporate ESG budget becomes real impact through four steps: choose a specific outcome, fund a dedicated team to deliver it, measure the result to a standard an outside party accepts, and report it with the trail intact, the discipline Mezyan sets out in its guide to verifiable carbon data. Each step converts intention into evidence, and evidence into the confidence to fund the next project.
Exhibit 1
The pledge-to-project pipeline: four steps from ESG budget to verified impact
| Step | Action | What it produces |
|---|---|---|
| 1 | Choose a specific outcome | One measurable result the budget will buy |
| 2 | Fund a dedicated team | Capacity committed to delivering that outcome |
| 3 | Measure to an external standard | A result quantified to a standard an outside party accepts |
| 4 | Report with the trail intact | Auditable evidence that unlocks the next round of funding |

Where companies start
Corporates with ESG budgets can channel the money into a specific, measurable project, which turns a line item into a delivered outcome. Foundations can structure results-based grants, paying on delivery so capital follows proof. Investors can blend their capital with corporate and public funds, where a measured project lowers the risk that holds private money back.
Organisations ready to move a budget line into a delivered, verifiable outcome can work with Mezyan to measure and verify the result that makes the next round of funding possible.
FAQ
What is the SDG financing gap?
The shortfall between the money needed to reach the Sustainable Development Goals by 2030 and the money currently committed, estimated by the UN at more than 4 trillion dollars a year for developing countries.
How do corporate ESG budgets create real impact?
By funding specific, measurable projects and verifying the outcome, which turns a broad pledge into evidence of change.
What is an advance market commitment?
A pledge by buyers to purchase a future outcome, giving project developers the revenue certainty to build. Frontier is a leading example in carbon removal.
