Impact metric

The source claims the product removes or stores more carbon than its production emits — typically bio-based products counting biogenic carbon storage.

You might see it written as: carbon negative · climate positive · carbon storing · sequesters carbon

Speaks to: Climate health

Often stated without the evidence to back it up — verify before specifying.

    Must be at least: Third-party verified

    Check it states: Global Warming Potential, Biogenic Carbon Reporting, System Boundary

    Check whether biogenic carbon is reported separately (EN 15804+A2 requires it).
