Climpact — open-weight expert on climate trials

The problem

Climate litigation is expanding worldwide. The research question behind Climpact is whether it actually works: if, how, when, and why courtroom action translates into real-world change.

Generic language models are the wrong instrument. They have read the internet; they have not been held to a golden set of court trials. The work is to make an open-weight model expert on that set.

Approach

Fine-tune openly released weights on a curated golden set of climate-litigation trials. Training and evaluation stay on that labelled set.

Outcome

An open-weight model specialised on a golden set of court trials — a climate-trial expert the project can own, rather than a generic assistant.
