Ask HN: How to Work Sustainably as a Data Scientist?

Hi HN!

I'm a Data Scientist who has worked for some time in predictive maintenance, specifically for the chemical industry. I'll go back to university to study a Master's degree in Data Science, but already want to extend my horizon with interesting fields to work in.

I would like to do something meaningful and would like to find out what's possible perhaps in green tech, education, or other fields I'm not aware of. Making the chemical industry greener is obviously something with a potentially great effect, but it's very difficult to get datasets one could develop a product with.

Any ideas?
