    September 2023 The Sustainability Mythbuster from a software engineering perspective
  2. We need to decarbonize the entire world of software engineering

    hardware production commute to/from work heating / cooling datacenter operation (energy) energy production network data transfer business travel food at work accommodation energy consumption . . . . . . . . . . . . conferences virtual meetings / zoom calls
  3. Sometimes it sounds like we are already close, almost done

    we are running on 100% renewable energy this (<insert random product>) is 100% carbon neutral we aim for net-zero by 20xx the green cloud we are producing renewable energy on-site we switched to a di ff erent language zero waste we do virtual meetings only we deploy to a public cloud, that takes care of everything
  4. Reducing Emissions Eliminate (do not emit carbon) Offset (continue emit

    carbon) Compensate (ask someone else to not emit carbon) Neutralize (remove existing carbon from atmosphere)
  5. Reducing Emissions Eliminate (do not emit carbon) Offset (continue emit

    carbon) Compensate (ask someone else to not emit carbon) Neutralize (remove existing carbon from atmosphere) Carbon Neutral
  6. Reducing Emissions Eliminate (do not emit carbon) Offset (continue emit

    carbon) Compensate (ask someone else to not emit carbon) Neutralize (remove existing carbon from atmosphere) Net Zero
  7. There is not enough renewable energy production (yet) - wasting

    green energy causes more fossil energy production somewhere else
  8. Zombies are a real problem Related study: Jonathan Koomey &
