W3C has several environmental sustainability (s12y) related efforts, and there have been a few sustainability focused sessions at W3C meetings.

This page is also the home page for the overall W3C Sustainability Community Group, which you may join here:

Work Areas

The following work areas of interest were identified at the 2022 s12y CG meeting / breakout session at TPAC 2022, with participants eager to work on each:

Technologies to reduce energy usage

Focusing more on new technologies, or new adoption of technologies that could reduce internet use of energy. E.g.:

  • multicast

Participants interested in working on this:

  • Jake Holland
  • Yoav Weiss

W3C meetings and operations

What are the impacts of W3C meetings and operations meetings on sustainability? E.g.

  • W3C servers, hosting
  • in-person meetings
    • flights to/from meetings
    • hotel overhead


  • We wouldn’t want to discourage anyone from flying here to help solve the sustainability problem, focus on what’s most important to the problem.
  • We should not get distracted by it, focus on where we can have a bigger impact.

Areas of opportunity:

  • scalability of a good hybrid meetings solution

Participants interested in working on this:

  • Judy Brewer — Good hybrid meeting techniques, and sharing awesome research showing the scalable carbon savings from hybrid
  • Nick Doty


What can we measure and how can we communicate those measurements relating to energy usage? E.g. things to measure:

  • servers could report how much energy, what kinds of energy going into producing this content
  • what are the different variables, what are the blind spots
  • data being presented to end users (W3C is not very good at exposing data to users to help make decisions)

Participants interested in working on this:

  • Jake Holland — Akamai has a sustainability commitment, if I can get access to a good standard for reporting usage I will push measurement within akamai and return feedback on problems with applying the metrics if possible
  • Mike Prorock
  • Yoav Weiss
  • Ivan Herman
  • Aram Zucker-Scharff
  • Phil Archer — by which I mean certified measurements against defined method
  • Zoe Lopez-Latorre

System Effects

What are the system level effects, and systemic aspects that we can investigate, understand, and work to solve at higher level to have a greater impact overall?

  • Any meaningful response has to be at the system effects
  • Make it easy for people, users, consumers to see impacts of what they’re doing, so they can each take action in scalable distributed ways

Participants interested in working on this:

  • Tantek Çelik
  • James Graham
  • Mike Prorock

Horizontal Review

  • must be obtainable
  • start with a checklist or questionnaire like the Security & Privacy Questionnaire
  • make it lightweight

Participants interested in working on this:

  • Tantek Çelik
  • Valerie Young
  • Nick Doty


  • Principles document would be most useful
  • Documents that can be shared with organizations for them to share internally and prioritize their own efforts accordingly

Participants interested in working on this:

  • Tantek Çelik
  • James Graham
  • Max Gendler
  • Tzviya Siegman
  • Aram Zucker-Scharff
  • Nick Doty

Sustainable Web Design

Draft Sustainable Web Design sustyweb) CG charter:

Participants interested in working on this:

  • Tim Frick - co-chair

Works in progress



Sustainability CG

Created on Earth Day 2022 with the W3C #sustainability community on Slack!

The W3C Sustainability CG is focused on the sustainability of web technologies in general (rather than a specific use like a website), present & future (proposals etc.), and evaluating them from a horizontal review perspective.

Current primary goal: establish and help evaluate environmental sustainability of new web technology proposals, similar to the horizontal reviews of accessibility, internationalization, privacy, and security.
