Post Description

We built a GitHub Action that posts carbon and cost diffs on Terraform PRs. No AWS credentials required – it parses the plan JSON offline. Emission factors are in a static JSON file, math is MIT-licensed. AWS-only, EC2/RDS only for now. Curious what the HN crowd thinks of the methodology approach.
