| # 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. | |
| Inherits CC BY-NC-SA 4.0 (non-commercial). Do not use to label a company deceptive. | |
