Introducing Unwritten’s AI Climate and Nature Due Diligence Tool for Private Markets

In a first-of-a-kind innovation, Unwritten launches the AI Climate and Nature Due Diligence Tool for Private Markets. Developed alongside Unwritten's general partner (GP) clients and expert advisors, the tool combines secure deep-web research with Unwritten's physical, transition and nature risk modelling. This feature makes climate due diligence clear enough for the deal team and rigorous enough for the investment committee (IC).

Closing the Gap: Why do most climate risk insights fail to change investment decisions?

Most climate risk insights in private markets are built in a vacuum. They are ambiguous and rarely change an investment or value creation decision.

A score or a scenario output on its own does not tell a deal team what it means for the asset in front of them. Deal teams need to know what actually happened the last time a climate shock hit, how peers compare, what competitors are doing to adapt, and how regulation and markets are shifting.

Unwritten built the AI Climate Due Diligence Tool to close that gap. It makes climate due diligence actionable, commercial and contextualised.

Key Features: What does Unwritten's AI Climate Due Diligence Tool do?

Unwritten's AI combines forward-looking scenario analysis with climate-related market intelligence from deep research, all in minutes. The tool does eight things that standalone climate risk scores do not.

1. Combines forward-looking scenario analysis with impact metrics. Physical, transition and nature risk are modelled over the hold period, not just at a single point in time.

2. Shows what happened during past climate shocks. The memo includes data on disruption from historic climate events, such as storm surges, and how long operations were affected.

3. Benchmarks the target against peers. Peer comparisons show how similar companies fared and what competitors are doing to adapt.

4. Sets out the regulatory and market context. Policy and market developments around the target are brought into the same view as the risk modelling.

5. Shows how physical, transition and nature risks interact. The tool treats these risks as connected rather than as three separate reports.

6. Flags correlation risks across holdings. GPs can see where a new acquisition adds to climate exposure already in the portfolio.

7. Sequences adaptation measures across the hold period. Proposed adaptation measures are ordered into a plan the deal team can carry into the value creation plan.

8. Evidences every source and shows where the gaps remain. Every finding is traceable, and missing data is listed rather than hidden.

The Output: What is in an Unwritten climate due diligence report?

Each Unwritten climate due diligence memo is organised into three sections a deal team can act on.

Key risk items

Key risk items set out the most material climate and nature risks at each site, with severity and impact metrics. For example, an extreme storm surge risk at a site might be quantified by water depth, expected outage days and the share of asset value at risk.

Value creation plans

Value creation plans turn risks into sequenced actions across the hold period. Examples include scoping surge-protection capex at an exposed site, building a water strategy or running a seismic remediation programme.

Diligence gaps

Diligence gaps list the information still needed to firm up the assessment, such as ownership type for each asset, site-level revenue, inventory exposure or insurance terms. Deal teams can take these straight into management Q&A with the target.

The Audience: Who is the AI Climate Due Diligence Tool for?

The tool is built for private equity and infrastructure investors who need climate due diligence that holds up from first look to IC approval.

• Deal teams get a clear memo in minutes, with risks, actions and open questions they can use during the deal process.

• Investment committees get rigorous, source-evidenced analysis that links climate and nature risk to value at risk and value creation.

• Sustainability teams spend less time on manual research and consultant hours, and more time shaping how portfolio companies (PortCos) adapt after the deal.

The tool works for both private equity buyouts and infrastructure acquisitions, and sits within the same Unwritten platform GPs use for portfolio monitoring and reporting.
