Global CO2 emissions from fossil fuels annually since 1750 through 2024.

Data

Data comes from the Global Carbon Project (GCP) annual Global Carbon Budget release.

• Source: Andrew, R. M., & Peters, G. P. (2025). The Global Carbon Project's fossil CO2 emissions dataset (2025v15). Zenodo. https://doi.org/10.5281/zenodo.17417124
• Coverage: 1750–2024 (updated annually each December after the GCP release)
• Units: global.csv values are in million metric tonnes of Carbon (MtC). data/fuel-breakdown.csv values are in million metric tonnes of CO2 (MtCO2).

Updating

Run the update script to fetch the latest GCP data:

python3 scripts/update.py

This fetches the GCP flat CSV from Zenodo, filters for global aggregates, converts units, and overwrites global.csv and data/fuel-breakdown.csv. A GitHub Actions workflow runs this automatically each December.

To update to a specific GCP release, edit the GCP_URL constant in scripts/update.py.
