What it looks like
- A carbon-per-unit measure, calculated from resource use and grid intensity.
- A target for each service, reviewed as part of the normal cycle.
- Dashboards that show it next to latency and cost.
Joined-up with cost
Energy and cloud cost are closely linked, so many efficiency changes help both. Where they diverge, make the trade-off visible rather than optimising one in secret.
How to start
- Choose one service and one carbon measure.
- Add it to the existing dashboard.
- Set a modest target and watch for a quarter.
- Add it to design reviews for new work.
