Carbon Recommendations Ranker

What this free tool does for you

Turn the carbon-saving recommendations Azure and Google Cloud already give you into one ranked list, with the carbon and the money of each fix side by side.

How to use it

  1. Open How to get your data: copy the Azure query or the gcloud command and run it.
  2. Drop the CSV or JSON files in, or click Load a worked example.
  3. Choose Carbon, Money or Carbon for the money to rank the fixes.
  4. Read Every fix, ranked, then the totals by kind of fix and by subscription or project, and download the list.

Good to know

  • The top few. A handful of fixes usually holds most of the carbon: the page says how many give 80%.
  • AWS. AWS gives no carbon per recommendation; the EC2 calculator shows the carbon of each fix instead.
Before you start: what to have readyShow
  • Azure: one query in Resource Graph Explorer, downloaded as CSV.
  • Google Cloud: one gcloud command per project, saved as JSON.
Recommendations

Azure's Resource Graph CSV, the gcloud JSON, or any CSV with a carbon-saving column.

On AWS? Cost Optimization Hub and Compute Optimizer give no carbon figure per recommendation. The EC2 idle and rightsizing calculator now shows the carbon of each fix beside its saving.

Want this done on your real bill?

Questions

Which clouds give a carbon figure per recommendation?

Azure and Google Cloud. Azure’s carbon optimization puts a monthly carbon saving on each right-size or shut-down recommendation for VMs and scale sets. Google’s unattended project recommender gives the carbon and cost of each project nobody uses. AWS gives none: Cost Optimization Hub and Compute Optimizer report cost only.

Whose carbon figures are these?

The providers’. This page reads them, converts them to a month and a year, and ranks them; it does not estimate them again. Azure’s are in kilograms a month; Google’s over the last 30 days.

What is "saved per tonne"?

The money a fix saves for every tonne of CO2e it avoids. Carbon cuts usually cost money; these pay you, because every one is also a cost saving. A high figure is a fix the finance team will like; a low one, a fix that is mostly about the carbon.

Can I load another tool’s recommendations?

Yes, as a CSV with a carbon-saving column, such as "carbon savings (kg)", and a cost-saving one. The header decides kilograms or tonnes and month or year; where it does not say, the page says what it assumed.

Is my data uploaded?

No. The files are read by JavaScript in this browser and never sent anywhere, unless you choose "Share for a review" under the results, which saves the files you loaded for Finitizer to look at, under a reference you can quote.

A list of fixes is a start. Finitizer turns them into done work.

Finitizer ranks the fixes across every cloud by cost and carbon together, assigns them, and tracks the savings as they land, so the carbon cut shows up in the next report.
