Claims

Claims by category

Signed records of real-world environmental data: energy, transport, emissions, water, soil and air. Pick a category to read each claim in plain words, see who reported it, and how far it has been checked.

Records on this page are what the chain stored. They are not a finding that a meter reading or a trip was true. Totals count each event once: an independent meter reading is shown as evidence on the site's record and is not added again. Records marked simulated come from the Carbon12 agent simulation (fictional actors), not real sites.
