In autumn 2026, we’ll open a Sandbox cohort for testing innovative climate scenario tools or approaches. Find out if this will apply to you.
The planned climate scenarios cohort will be part of the Regulatory Sandbox.
We will be inviting firms and specialists to test innovative approaches, whether quantitative or narrative based.
This cohort is aligned with the FCA’s regulatory approach, which aims to ensure that market participants manage the risks of moving to a more sustainable economy, as well as the risks from a changing climate.
We update this page as planning progresses.
Why we’re focusing on climate scenarios
Through the FCA’s engagement with experts in scenario analysis, and ongoing dialogue with industry representatives through the Climate Financial Risk Forum (CFRF)[3], we have identified clear opportunities to innovate in how climate risks are assessed and applied in practice.
Who should apply
- Firms or specialists whose approaches incorporate innovative approaches to climate scenarios. These may include:
- Plausible low-probability, high-impact risks.
- Tipping points.
- Non-linear impacts.
- Second-order and compounding effects.
- Subnational and sector-specific impacts, reverse stress testing.
- Approaches informed by deep uncertainty.
- Firms that are ready to test their climate scenario tools and share their insights with the FCA.
What you'll get from the Sandbox
- Test your product: try out your climate scenario solutions in a controlled environment, either with consumers live in the market or using firm data.
- Support and feedback: get guidance from our Innovation case officers and feedback on your application.
- Visibility: successful applicants will be listed publicly on our website, although acceptance is not an endorsement.
What happens next
We expect to publish key dates and details on how to apply in autumn 2026.
