### Dataset Summary

We introduce an expert-annotated dataset for detecting real-world environmental claims made by listed companies.

### Supported Tasks and Leaderboards

The dataset supports a binary classification task of whether a given sentence is an environmental claim or not.

### Languages

The text in the dataset is in English.

## Dataset Structure

### Data Instances

```
{
    "text": "It will enable E.ON to acquire and leverage a comprehensive understanding of the transfor- mation of the energy system and the interplay between the individual submarkets in regional and local energy supply sys- tems.",
    "label": 0
}
```

### Data Fields

- text: a sentence extracted from corporate annual reports, sustainability reports and earning calls transcripts
- label: the label (0 -> no environmental claim, 1 -> environmental claim)

### Data Splits

The dataset is split into:
- train: 2,400
- validation: 300
- test: 300
