From good ideas to funded projects
Most sustainability teams aren’t short on ideas. They have targets, audit findings, and a list of projects worth doing. What they’re short on is a way to move those projects through the same capital approval process that governs everything else the business spends money on.
This guide makes the case for treating sustainability as a capital allocation problem—with the same baselines, hurdle rates, and evidence Finance applies to any other investment. It covers what makes a project investable, how to sequence a portfolio, how to write a business case that clears committee, which funding instruments to use, and how to verify results in a way that funds the next round.
Inside the eBook:
Why good projects lose the budget fight
The difference between a technically sound project and a fundable one, and the translation gap between sustainability language and Finance’s language of return, risk, and useful life.
Why one evaluation test distorts a mixed portfolio
Different projects create value through different mechanisms. Cost reduction, risk avoidance, asset protection, and strategic access each require a different test, and running everything through the same payback screen is how important work fails to clear.
How to segment a portfolio and sequence the spend
Sorting assets before scoring projects keeps the pipeline from filling with proposals that can’t be executed. Layering the spend produces early evidence that funds what comes next.
Which instruments release the capital
Internal carbon pricing, green debt, incentive capture, efficiency-as-a-service, and C-PACE, and how to match each to the right constraint before the funding windows close.
