# GreenTruth Claim Detector

Binary classifier flagging whether a sentence is an environmental claim. Text stage
of GreenTruth, which checks environmental claims against Earth-observation evidence.

## Intended use
Find checkable environmental claims in corporate disclosures, before evidence-grounded
verification. Detecting a claim is not judging it.

## Training
Fine-tuned climatebert/distilroberta-base-climate-f on the environmental_claims dataset
(Stammbach et al., ACL 2023): 3 epochs, lr 2e-5, batch 16, max length 256.

## Evaluation
See the notebook run for test precision/recall/macro-F1/accuracy. The paper reports
macro-F1 around 85% for comparable models.

## Limitations & ethics
English, listed-company text; domain shift is likely. Detects a claim, not its truth.
