IT software and hardware are taking an increasingly large bite out of our C02 emissions and energy consumption.
Therefore, we have optimized our website to consume as little as possible at elek pageview.
The main tool we use for this is Ecograder.com

Another tool is the Website Carbon Calculator, which does give a little less detail on what exactly you can improve.
