Our Services

Green Umweltberatung supports plant operators with specialized biogas and biomethane consulting services addressing key regulatory, economic, and operational requirements related to biogas and biomethane. Our services range from assisting with certifications and audits, including GHG, Nabisy, and UDB processes, to supporting the EEG tendering process and providing practical training.

Regulatory requirements in the biogas and biomethane industry are complex, dynamic, and economically significant. We help you establish robust processes, reduce audit risks, and ensure long-term marketability.

We provide plant operators with structured, audit-ready support throughout complex certification processes. This includes selecting suitable certification schemes such as REDcert, SURE, or ISCC; preparing all relevant documentation; optimizing existing processes; and providing support through to successful certification and recertification.

We assist operators with GHG calculations, the maintenance and quality assurance of reporting data in the Nabisy system, as well as with the setup, updating, and management of the EU database. The goal is to ensure reliable, timely, and audit-proof processing throughout the entire supply chain.

We support projects from the initial economic assessment through business case and scenario analysis to the development of a suitable bidding strategy and the structured preparation of the tender process. In this way, we provide a solid foundation for decision-making and enhance the feasibility of your projects.

Our training courses provide practical knowledge on certification systems, GHG calculations, Nabisy, UDB, and current regulatory developments. The courses are tailored to plant operators, administrative staff, compliance officers, marketing professionals, and executives, and can be customized to meet your specific needs.
