 ## Model Description
 
-Based on [this paper]{https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4599483}, this is the fine-tuned ClimateBERT language model with a classification head for detecting sentences that are either related to emission net zero or reduction targets.

 We use the [climatebert/distilroberta-base-climate-f](https://huggingface.co/climatebert/distilroberta-base-climate-f) language model as a starting point and fine-tuned it on our human-annotated dataset.
