Calculate environmental cost?

Hello team!
Thanks for this cool package!

This is more of a suggestion than a feature request.
There is this package that estimates the environmental impact of calling an Generative AI ==> https://github.com/genai-impact/ecologits.
Maybe it could be interesting to find synergies between both?

For example, an idea would be to expose a similar function to `calculate_completion_cost` (e.g. calculate_environmental_cost) that uses ecologits to estimate this impact.
