The past month or so on linkedin I've been seeing Dryden Williams making informative posts about website carbon emissions.

Having seen his posts a few times I decided to try his service https://ecoping.earth . To highlight areas to improve usedandloved.com ...

I've known for a while that my site was resource heavy but as a young startup had to prioritise shipping features.
