What this tool is for

01 · Start here
Who it is for

For the conversation between sustainability or risk and finance. You build the case. Finance tests it. Both sides read the same numbers.

What you get

What it may be worth investing in climate adaptation, as CapEx and OpEx, at the payback your company expects. Plus a profile of the levers that create this value.

What it is not

An investment appraisal, a risk assessment or a valuation. It is a sandbox for ideas. It covers physical climate effects such as heat, flood, storm and drought. CO2 pricing and transition risk sit outside.

What you need

Five figures from your annual report, your payback expectation and about 30 minutes. Where you have no number yet, keep the example value. The result shows which inputs are still examples.

How the tool works, in four steps: set your company numbers, prepare your data (optional), set the eight levers, read what it may be worth investing.

Sandbox for ideas. No investment appraisal. Sandbox for ideas. No investment appraisal. This tool is a sandbox for generating ideas and for internal discussion only. It replaces no investment appraisal, no risk assessment and no professional advice, and it gives no financial, investment, legal, tax or insurance advice. All example values, benchmarks and results are illustrative and unverified for your company, and every forward-looking figure is uncertain. Do not use the results for external reporting, disclosure, audit, or communication with investors, lenders or insurers.

Nothing you enter is stored until you sign in and choose to save it. Results are illustrative and do not constitute financial advice.
