Did you know that more than 250 000 websites are published every day? The majority uses too heavy fonts, too large/unnecessary images or utilises redundant libraries. These and other factors generate the carbon footprint. Actually, one view of an average website emits 4.6 g CO2 which sums up to 553 kg CO2 annually. Unfortunately, current solutions optimise only already existing websites. ec0lint is a tool for frontend developers that mitigates the carbon footprint of websites. It shows tips advising how to create a more climate-friendly code. Thanks to code optimization ec0lint can help in reducing CO2 emissions per one view from 4.6 g to ~0.2 g saving 529 kg CO2 (-96%!) annually. In the keynote, we want to share our knowledge about digital ecology with the audience, tips and tricks on how to mitigate digital footprint and information about the tool we created.
