1000 Ideas

There are thousands of things we can do to advance a more sustainable internet. Here you’ll find a list of the ones we gathered through brainstorming, workshops, and feedback. We've used a "double diamond" approach, i.e. we went as wide and broad as possible, generating ideas regardless of feasibility or likelihood. You can keep adding to them and help us link out to projects and research that may bring them to life. We then narrowed these down to a few top ones (below) that have sparked most feedback and engagement so far.

This is an ongoing collection of ideas and inspiration. Feel free to add and annotate!

Top Ideas (to date)

It’s a living document, what flies and what doesn’t will change as we keep iterating and learning about what’s possible and desirable for greater environmental sustainability on the internet.

Sustainability Engineering as a career pathway

  • Sustainability engineering should be a recognized professional specialization as well as a skill integrated across the engineering field.
  • Similar to accessibility in web development, sustainability should be foundational in any developer's practice. See:
  • Sustainability engineering should be incorporated into computer science courses, educational programs, on the job training.

Carbon accountability

  • Learn to count emissions. Ensure your budgets account for carbon costs, including inaction, as well as financial ones.
  • Encourage and teach others to set carbon budgets.
  • Publish carbon calculations and sustainability reports in machine-readable formats.
  • Use Platform, Packets and Process to categorize carbon costs for digital projects.
  • Quantify and openly publish tests and measurements about the carbon footprint of your digital work. Compare that carbon cost of other activities, like flying or running a load of laundry. This helps build a better understanding of how "expensive" internet-related activities are.
  •, but for carbon.

Change the Aesthetic

  • What is desirable in one era can seem outdated and undesirable years later when societal norms change. We should design and code for a new sensibility, one that is irresistibly sustainable.
  • Think of tech as a fashion-driven industry. Make the transition irresistible, and the everyday injustices outrageous.

Employee Action

  • Jobs may change, but we only have one planet. There are a lot of questions employees and prospective hires can ask (and do):
    • For example: "Does this company collaborate with the fossil fuel industry?"
    • Is there a public commitment to net zero emissions?
    • Is there a public timeline to reach net zero emissions?
    • Are there public independent audits of progress on the way?
    • Is there disclosure of how much revenue or business partnerships come from projects to help extract fossil fuels?

Use equity for equity

  • The work you do isn't the only lever you have. Money works for you too.
  • Shares in your pension delay climate action - ask and switch.
  • Stock you are paid in can force discussions that need to happen.
  • Divest your pension.

Time to serve the planet

  • Make time to contribute to climate action.
  • Many organizations support the model of 20% time, meaning that you have some hours during your work week to explore something that you care about. Other models include dedicating a day a week, like Fridays, to commit to working on this. Whatever the model that suits you, it's about prioritizing the issue by putting your time to it.
  • Develop organisational, local, national, or regional programmes like a civil service for environmental sustainability.

Fight denial

  • Understand that algorithms and misinformation play a key role in delaying climate action.
  • Develop information recommendation algorithms in a way that favor science-based information.
  • Optimise for truth, not clicks.

Extend the lifecycle of electronics

  • Hardware and electronics that are connected to and power the internet are also extremely expensive for the planet. Most electronics, such as mobile phones, have a very short lifespan. Advocate for extending their usage.
  • Advocate for the right to repair, the design and development of more modular and easily repaired electronics, the skills and support systems to repair, e-waste re-purposing and recycling, and better organizational policies to use hardware for longer.
