We provide plant operators with structured, audit-ready guidance through complex certification processes in the biogas and biomethane sectors. From system selection and documentation to successful auditing, we support you with practical and reliable advice.
Support for Certifications & Audits
Current situation and common challenges
Certifications and audits in the biogas and biomethane sector are subject to stringent regulatory and operational requirements. Differing system approaches, dynamic requirements, and the significant effort involved in documentation and verification often lead to uncertainty during implementation. At the same time, audit non-conformities and misalignments between operators, auditors, and other market participants can have economic consequences.
Typical challenges include, among others:
- Complex regulatory requirements under RED II / RED III
- Different system frameworks such as REDcert, SURE, and ISCC
- Significant documentation and verification requirements
- Audit risks with financial implications
- Uncertainties at the interfaces with Nabisy, UDB, and supply chains

Our structured consulting approach
We guide operators through the entire certification process in a structured manner — from assessing the initial situation to the long-term development of existing processes. In doing so, we provide support not only at the conceptual level but also in very concrete ways, such as selecting suitable certification systems, establishing an audit-proof record-keeping system, preparing relevant documentation, and preparing for and supporting audits. In addition, we provide practical training to ensure that regulatory requirements are clearly understood and implemented internally.
We analyze your current situation, assess regulatory requirements, and work with you to select the appropriate certification system. In doing so, we identify relevant areas for action and establish a solid foundation for further implementation.
We assist you in establishing or optimizing your record-keeping system, creating audit-ready documentation, and integrating these requirements into existing processes. This also includes structured preparation for audits and the coordination of relevant evidence and documentation.
We assist with audit and inspection preparations, help track relevant requirements, and identify opportunities to optimize existing processes. In addition, we help you adapt to regulatory changes and prepare your organization for recertification and future audit requirements.
In addition, we offer practical training on certification systems, documentation, and audit requirements. This helps ensure compliance with regulatory requirements and strengthens operational implementation in day-to-day business.
The benefits for you as an operator
Our goal is to ensure that certification and testing processes are not only compliant with regulations but also efficient and robust. This allows us to provide greater certainty during audit preparation, reduce the strain on internal resources, and enhance the marketability of your facility.
Additional certification services

In addition to supporting traditional certification and verification processes, we also assist with the structured development of certifiable CO₂ projects on forested land. We work with landowners and project managers from the initial identification of suitable sites, through the analysis of CO₂ potential and project viability, to the preparation of certification, monitoring, and verification processes.
The goal is to establish a solid foundation for subsequent certification, market positioning, and economic utilization.
Our support includes, among other things:
- Identification of suitable sites and management approaches
- Assessment of the prerequisites for a potential certification project
- Analysis of CO₂ potential and project viability
- Development of certification, monitoring, and verification processes
- Support with positioning, marketing, and partner outreach
