## What it is
Cloud Carbon Footprint is an open-source application that estimates energy consumption (kWh) and carbon emissions (metric tons CO2e) from public cloud usage across AWS, Google Cloud, and Azure. It exposes its estimation logic through a CLI, an API, and a web dashboard for measuring, monitoring, and reporting cloud carbon emissions.

## Use cases
- estimate carbon emissions from my AWS cloud usage
- measure our cloud carbon footprint for Scope 3 reporting
- track energy consumption of cloud instances across providers
- find opportunities to reduce cloud waste and emissions
- generate sustainability reports for cloud infrastructure
- monitor cloud carbon emissions over time in a dashboard

## When to choose
- you use AWS, GCP, or Azure and need visibility into cloud energy and emissions
- you need to report cloud emissions as part of corporate sustainability targets
- you want an open-source, self-hostable alternative to vendor carbon dashboards
- you want to embed emissions estimation logic into your own tooling via its packages or API

## When to avoid
- you need exact, metered emissions data rather than methodology-based estimates
- your infrastructure is on-premises or on a non-supported cloud provider
- you need real-time emissions monitoring rather than periodic estimation
- you require certified or audited carbon accounting for compliance
