Germany's Fuel Emissions Trading Act (BEHG), implemented in 2021, established a national Emissions Trading System (nEHS) for heating, transport, and, from 2024, the waste sector. It prices CO2 emissions from fossil fuels not under the EU system, with certificate prices set at 45 euros per tonne of CO2 in 2025, transitioning to auctions from 2026. Amendments require companies receiving carbon leakage aid (BECV) to invest in climate protection, covering at least 50% of aid in 2023-2024 and 80% from 2025 onwards. The system also expanded to include products like Jet A-1 fuel and mandates annual emissions reports via the DEHSt platform, with certificate purchase and surrender via the nEHS registry.
