BEHG-Compliant
Biomethane Supply in Germany
Germany’s Fuel Emissions Trading Act is increasing the cost of fossil gas. Certified biomethane offers a compliant route to reduce fossil exposure within the German framework when sustainability proof, mass balance and registry handling are correctly managed. BioGem Express supports sourcing, certification coordination and delivery across regulated European markets.
What is the BEHG and why does it matter?
The Brennstoffemissionshandelsgesetz (BEHG) — Germany’s Fuel Emissions Trading Act — requires the entities that place fuels on the German market to acquire CO₂ certificates for the associated emissions. In practice, the legal obligation sits primarily with fuel suppliers and other market participants upstream, while large gas consumers are affected commercially through pricing, supply structures and reporting requirements, as outlined by DEHSt’s guidance on the national emissions trading system.
Since its introduction in 2021, the BEHG has steadily increased CO₂ pricing pressure on fossil gas. In 2026, certificates move into an auction-based corridor of €55 to €65 per tCO₂, before ETS II takes over from 2027, according to DEHSt. For gas-intensive operators, this makes compliant renewable gas procurement increasingly strategic.
Certified biomethane offers a direct route to lowering fossil exposure. Where compliant biomethane is sourced, certified and documented correctly, the obligated party can reduce the fossil share that would otherwise trigger BEHG certificate costs.
Sustainability proof has been mandatory for biomethane used under the EU ETS since 2022. With the current ETS I carbon price at roughly €55–60 per tCO₂, the cost advantage of certified biomethane over fossil gas is approximately €16 per MWh of CO₂ avoidance — a figure that grows significantly as allowance prices rise.

How biomethane addresses BEHG obligations
Certified biomethane can support BEHG compliance when sustainability certification, Nabisy proof and mass-balance documentation are correctly aligned.
Produced & certified
Biomethane is produced from organic feedstocks — including agriculture residues, manure, biowaste and crop — and upgraded to natural gas quality. For BEHG use, the relevant sustainability proof is typically verified under recognised RED voluntary schemes such as ISCC EU or REDcert EU.
Injected & tracked
Certified biomethane is injected into the gas grid and tracked through contractual documentation and mass balance. For the German BEHG framework, Proof of Sustainability (PoS) and Nabisy-linked verification are central; Guarantees of Origin can support disclosure, but according to ISCC EU Mass Balance Guidance they do not replace PoS.
Obligation reduced
The obligated party uses the certified biomethane volumes and associated sustainability proof within the reporting framework. This reduces the fossil share subject to BEHG certificate costs and supports audit-ready reporting to the competent authorities.
What BEHG-compliant biomethane requires
Not all biomethane qualifies for BEHG compliance. Specific sustainability, traceability, and documentation standards must be met throughout the supply chain.
Sustainability certification
Biomethane used for BEHG purposes is typically verified under recognised RED voluntary schemes such as ISCC EU or REDcert EU. In practice, the key thresholds are a greenhouse-gas reduction of at least 70% for installations starting operation from 2021 to 2025 and at least 80% from 2026, as reflected in the ISCC EU system documents and industry guidance.
Eligible feedstocks
There are no direct restrictions regarding the feedstock mix. What matters is whether the required greenhouse-gas reduction is achieved. Certification of the biomethane plant operator is crucial and decides whether the biomethane is eligible for BEHG.
Full chain of custody
Documentation must cover the full supply chain — from feedstock origin to final use. Mass balance must be maintained throughout the chain of custody, and the relevant proof must be robust enough to avoid double counting and support audits.
GHG reporting to DEHSt
The obligated entity must be able to substantiate the relevant volumes and sustainability information within the German reporting framework. BioGem Express supports clients with the documentation package needed for compliant, audit-ready handling.
Your ETS biomethane partner
ETS compliance isn’t a once-a-year exercise — it’s a live obligation with monitoring, reporting, and verification running continuously. The documentation behind your biomethane supply has to hold up to independent audit. That’s the standard we build to.
As a specialist biomethane trading company operating across regulated European markets, BioGem Express works with certified producers, accredited voluntary scheme bodies, and registry operators to deliver volumes where the sustainability proof is complete — every time, not just on paper.
“Carbon compliance is a numbers game. The ETS counts every tonne. We make sure the documentation behind your biomethane is as solid as the gas itself.”

Key questions on BEHG & Biomethane
The BEHG (Brennstoffemissionshandelsgesetz) is Germany’s Fuel Emissions Trading Act, requiring companies that place fossil fuels on the market to purchase CO₂ certificates for associated greenhouse gas emissions. It primarily applies to entities that place fuels on the German market, while industrial gas consumers are usually affected commercially rather than being the direct obligated party. DEHSt supervises the system.
Yes. Certified biomethane can be used within the BEHG framework when the relevant sustainability proof is correctly documented. For BEHG use, recognised RED certification and Nabisy-linked proof are central, and the required GHG reduction thresholds must be met.
BEHG-compliant biomethane is typically verified under recognised RED voluntary schemes such as ISCC EU or REDcert EU. Complete chain-of-custody documentation and the relevant Nabisy-linked proof are required for robust reporting and audit purposes.
The BEHG is a CO₂ pricing framework for fossil fuels placed on the market. The GEG (Gebäudeenergiegesetz) governs renewable heat requirements in buildings. Both frameworks can involve biomethane, but the proof logic differs: BEHG relies on RED-based sustainability verification and Nabisy, while GEG follows a different evidence structure.
