Learn about Energy Attribute Certificates, DER verification, GridScore, CarbonScore, and how data infrastructure for demand-side energy works.

## What is an Independent Record for Energy?
Every distributed energy transaction has two sides. Both need a number they didn't produce. Here's what that means.

## How CarbonScore Works
CarbonScore measures the carbon impact of distributed energy resources by combining onsite emissions reductions with a balanced view of grid impacts.
