Editor's take on Azure Carbon Optimization
Fits Azure customers that want the provider's own emissions figures attributed down to subscriptions, resource groups and resources, with a reader role for teams that only need to view and CSV or REST export into sustainability reporting. The trade-off is scope and refresh: it reports Azure usage only, data is monthly with a 12-month retention window, and it works by pointing at idle or over-provisioned resources rather than benchmarking or forecasting. Multicloud estates need a second source. It is free, so the cost is governance effort rather than licence budget.

Fits platform teams on Kubernetes that run development or batch clusters with long idle windows and want pods suspended outside working hours to cut energy use and node spend. The trade-off is scope: it acts on scheduling and cluster scaling rather than on measuring emissions, so a carbon figure needs separate tooling, and the Green Dashboard that shows savings is described as coming soon. It is an operator with no API of its own recorded, so automation follows Kubernetes conventions. Teams needing per-workload metering or running clusters without idle periods should look elsewhere.
