Green Algorithms calculator

What's the carbon footprint of your computations?

i

The calculator data (carbon intensities, hardware...) is regularly updated. If you want to replicate results obtained in the past, select the corresponding data version.

Some news...

⏳ We are in the process of updating the carbon intensity values for electricity consumption to the latest data. Due to a change of T&C with carbonfootprint, this is taking a bit longer than planned.

🌱 Interested in green computing? We're recruiting for research roles at the University of Cambridge! More info here

🌱 The new major update of the calculator is here! Possibility to share your results as csv, more guidelines on how to use the tool, and the addition of a brand-new AI-specific calculator! Check out the release notes for the full list of new features.

🐞 It's always possible that some bugs have slipped through the net of this new release... If you spot one, just let us know here.
