# Dataset Card for Dataset Name

A dataset of 100 corporate sustainability reports with manually extracted scope 1, 2 and 3 greenhouse gas emission values.

## Dataset Details

### Dataset Description

Data about corporate greenhouse gas emissions is usually published only as part of sustainability report PDF's, which is not a machine-readable format, which is a tedious and time-consuming process. Interested actors have to manually extract emission data from these reports. An automatic information-extraction system could solve this issue.

To evaluate such information-extraction systems and to encourage research into solving this task, a dataset of sustainability reports and manually-extracted emission values is created and published.

### Dataset Sources [optional]

- **Repository:** https://github.com/nopperl/corporate_emission_reports
- **Paper [optional]:** [More Information Needed]
- **Demo [optional]:** [More Information Needed]

## Uses

The dataset is intended to be used to evaluate or develop automatic systems to extract machine-readable greenhouse gas emission data from sustainability reports.

## Dataset Structure

- `id` (string): unique instance id, ex. `"0012"`.
- `emission_year` (int): the year of the extracted emissions, which is useful in reports which contain information about multiple years.
- `scope_1` (double): total scope 1 emissions in metric tonnes of CO2eq.
- `scope_2_market` (double): total market-based scope 2 emissions in metric tonnes of CO2eq.
- `scope_2_location` (double): total location-based scope 2 emissions in metric tonnes of CO2eq.
- `scope_3` (double): total scope 3 emissions in metric tonnes of CO2eq.
- `scope_1_page` (list<int>): set of pages containing total scope 1 emission data.
- `scope_2_market_page` (list<int>): set of pages containing total market-based scope 2 emission data.
- `scope_2_location_page` (list<int>): set of pages containing total location-based scope 2 emission data.
- `scope_3_page` (list<int>): set of pages containing total scope 1 emission data.
- `url` (string): the URL to the sustainability report PDF.
- `sha256` (string): SHA-256 hash string of the report PDF, which should be used 
- `subset` (string): indication of whether the report comes from the set of Euro Stoxx 50 (`eurostoxx`), NYSE (`nyse`) or Nikkei 225 (`tyo`) corporations.

The remaining 15 fields contain the data for each of the [15 scope 3 emission categories](https://ghgprotocol.org/scope-3-calculation-guidance-2).

The dataset only contains the URL to the report PDF. A helper script to download these files is provided at: https://github.com/nopperl/corporate_emission_reports/blob/main/download_documents.py.

## Dataset Creation

### Curation Rationale

To our knowledge, there is no publicly-available dataset containing manually extracted (self-reported) greenhouse gas emission data from sustainability reports. Hence, this dataset was collected to enable the evaluation and development of automatic information-extraction systems.

### Source Data

The dataset is based on sustainability reports from corporations in Europe, North America and Asia.

#### Data Collection and Processing

To ensure geographic diversity, the sustainability reports are sourced from three sets of corporations. The first set consists of 39 corporations tracked by the Euro Stoxx 50 stock index as of 18 September 2023. Note that out of the missing 11 corporations of Euro Stoxx 50, 5 are not considered as no publicly-available sustainability reports were found and 6 are not considered it was not possible to extract unambiguous emission values. The second set is a random selection of 39 corporations listed on the New York Stock Exchange as of December 2023. The third set is a random selection of 22 corporations tracked by the Nikkei 225 index as of October 2023. Note, that this selection strategy is intentionally biased towards larger corporations due to the assumption that they have a higher likelihood of publishing sustainability reports.

For every corporation, the most recent sustainability report is downloaded from the official source. In some cases, the sustainability report is part of a larger annual report.

Sustainability reports based on the [Carbon Disclosure Project](https://www.cdp.net/en/guidance) or [Global Reporting Initiative](https://www.globalreporting.org/standards/) templates are not considered as they already follow a consistent structure.

#### Who are the source data producers?

The sustainability reports are produced by corporations themselves and optionally verified by third parties. Thus, they only contain self-reported emission information.

### Annotations [optional]

The sustainability reports are annotated with manually-extracted emission data, which forms the main purpose of this dataset.

#### Annotation process

The annotation was based on the greenhouse gas emission definitions of the [GHG Protocol Corporate Standard](https://ghgprotocol.org/corporate-standard):

- Scope 1: A reporting organization’s direct GHG emissions.
- Scope 2: A reporting organization’s emissions associated with the generation of electricity, heating/cooling, or steam purchased for own consumption.
- Scope 3: A reporting organization’s indirect emissions other than those covered in scope 2.

Only emission data about the reporting corporation was extracted, invidiual values for subsidiaries were ignored.

Scope 2 emissions are annoted as market-based by default if no indication about the calculation method is given in the report.

Values which could not be unambiguously extracted were noted as missing.

No automatic tools were used in the extraction process.

The extracted data is not validated by a third party or verified against other data sources.

#### Who are the annotators?

The data was annotated by a single person without special expertise in sustainability reporting.

#### Personal and Sensitive Information

The dataset contains only public information.

## Bias, Risks, and Limitations

The emission information was extracted by a single non-expert. No guarantee can be given that the data is completely correct.

The dataset does not contain sustainability reports of small enterprises or non-profit organisations.

Even though some care was taken to ensure geographic diversity, the dataset does not include sustainability reports from large parts of the world.
