The German biomethane stack today
Germany's biomethane compliance stack sits on top of the BImSchG (immissions law) framework, with the BLE as the central authority for sustainability claims, REDcert-DE and REDcert-EU as the dominant voluntary schemes, ISCC-EU as the alternative, and Nabisy as the national registry for biomethane HKN. The German GHG quota market is the largest single source of premium demand for certified biomethane in the EU.
GooClear was built specifically against this stack. The mass-balance ledger is REDcert-DE-aligned, the Nabisy bridge is direct, and reporting follows BLE expectations.
