The Chancery Lane Project releases open-source tool to help lawyers insert climate clauses into contracts

The Chancery Lane Project (TCLP), a UK legal charity, has released a free open‑source AI tool that provides lawyers with immediate access to about 200 contract clauses designed to reduce carbon emissions. The tool connects to legal AI assistants such as Harvey and Legora, as well as general‑purpose platforms like OpenAI's ChatGPT and Anthropic's Claude via APIs, allowing legal teams to copy and paste climate provisions into contracts after human review. Early adopters include the UK government's Cabinet Office, telecom company Vodafone, and law firm Clyde & Co. According to Felix Cohen, TCLP's director of digital, the tool cuts drafting time for environmental clauses from weeks to hours and helps lawyers overcome commercial and internal resistance to inserting climate‑friendly provisions. In addition to the API tool, TCLP launched an open‑source Model Context Protocol server that enables AI assistants to compare clauses, benchmark drafting and identify opportunities to strengthen climate provisions or reduce greenwashing risk. TCLP also introduced TCLP Labs, a digital platform with a tracker that monitors whether firms keep climate promises and flags clauses that contradict sustainability targets. Citing 2024 research by Wolters Kluwer, the organization notes that 68% of US law firms and corporate legal departments report increased demand for ESG legal expertise, yet only 41% of corporate legal professionals and 29% of law firms feel very prepared to meet that demand. For legal professionals, the tool represents a practical step toward integrating AI into everyday contract work, especially as ESG demands rise, offering standardized climate clauses that reduce drafting friction while keeping human oversight central.
