About

Gmail Carbon Score Analyzer helps you understand the environmental impact of your emails in real time, as you compose them.

The live carbon score based on:
- Email body length
- Number of recipients
- Size of attachments

See what’s driving up your footprint and get tips to reduce unnecessary digital emissions.

Why it matters:
Email infrastructure consumes significant resources. Sending fewer, lighter, and more focused messages reduces data center load and network bandwidth. Small changes at scale can make a difference.

Features:
- Floating badge that updates as you write
- On-click score breakdown (body, recipients, attachments)
- Automatic scoring as you type, attach, or edit
- Drag-and-drop badge position (saves your layout)
