Green and environment

  • Carbon emissions

 

  • Fossil fuels vs renewable energy

 

  • Carbon footprint and responsibilities

Have you ever thought about web emissions?

Internet emissions are huge

  • 20 billion devices in 2020
  • 1 Google search uses energy as light bulb for 17 s
  • Internet generates emissions like airline industry
  • If internet were a country, would be 6th for electricity usage
  • < 3% websites are powered by renewable energy (2020)

A sustainable web: is it possible?

By Nicola Zambello

A sustainable web: is it possible?

How much do we know about the impact of technologies we use everyday? How much the web industry is responsible for carbon emissions? Can we define an ethic development? I wrote the Sustainable Web Manifest and I'll tell you what does it mean. We'll look to the things that need to be fixed and the process to make a sustainable website. Finally, I’ll introduce an introspection in Volto issues and the future works as the result of my analysis. https://2021.ploneconf.org/schedule/a-sustainable-web-is-it-possible
