Nachhaltigkeitsbeauftragter Erneuerbare Energien

The core mission is to keep EnviTec's biogas plants and its customers certified as sustainable. That means preparing, organising and accompanying sustainability certifications and audits, which includes gathering the right documents beforehand, supporting the audit itself and following up on any findings. You would also create and maintain the sustainability evidence and related documentation that these certifications depend on. A second major responsibility is greenhouse gas calculation. You would carry out and evaluate THG calculations for plants and possibly for customers, work that feeds directly into whether a batch of biogas or bio-LNG qualifies as sustainable. On top of that, you monitor compliance with sustainability requirements and certification standards, watching for changes in the rules and checking that operations stay within them. The role also has a process side. The posting asks for support in developing and optimising the company's sustainability processes, so you would not just execute existing routines but look for ways to make certification work smoother across a growing number of plants and international markets. Close coordination with plant operators, certification bodies and internal departments runs through all of these tasks.

This role offers deep practical knowledge of sustainability certification in the renewable energy sector, particularly the schemes that govern biogas and bio-LNG. You would learn how greenhouse gas calculations are actually done, what evidence auditors expect and how the sustainability criteria for renewable fuels work in practice, knowledge that is in demand across the energy transition. Beyond certification itself, you would build familiarity with the biogas value chain, from feedstock and agricultural inputs through plant operation to fuel marketing. The posting values a basic understanding of agricultural processes, so exposure to that side is part of the job. Working with certification bodies and operators also develops coordination and communication skills that transfer to almost any sustainability role. There may be room to grow into process design, since the role includes supporting the further development of sustainability processes. Over time, someone in this seat could become the internal reference point for certification and THG matters, a position that carries weight in a company whose revenue depends on proving its products are sustainable.

The posting asks for a completed commercial, technical or agricultural education, which signals that this is not a role reserved for university graduates. First experience in sustainability management, certification or the energy sector is an advantage rather than a hard requirement, so someone early in their sustainability career with the right attitude could fit. Interest in renewable energy matters, and a basic grasp of agricultural processes is welcomed. On the practical side, confident use of MS Office, especially Excel, is explicitly required. The greenhouse gas calculations and documentation work mean spreadsheets are a daily tool. Good communication with both internal and external contacts is also listed, since the role coordinates between operators, certifiers and departments. Soft skills carry real weight here. The posting names teamwork plus an organised, structured and results-oriented way of working. Someone who enjoys keeping detailed records in order, follows up reliably and stays calm when audit deadlines approach would likely do well. German language ability is implied by the posting and the contact details, and would be needed for the certification and operator communication.

Lead with any hands-on exposure to certification, audits or sustainability documentation, even if it was a small part of a previous job. This posting treats experience in sustainability management, certification or the energy sector as an advantage, so a concrete example of preparing evidence for an audit or working with a certification scheme will stand out more than a general statement of interest in renewables. Show that you understand what biogas certification involves. Referring to sustainability criteria, greenhouse gas calculation or the idea that renewable fuels need documented proof would signal you have read the posting carefully and grasp why the role exists. If you have any agricultural background or familiarity with feedstock, mention it, since the posting values a basic understanding of agricultural processes. Since the role is coordination-heavy, use your cover letter to demonstrate organisation and communication. A brief example of keeping a documentation process on track or aligning several parties toward a deadline would fit well. Proof of solid Excel skills is also worth including, given the greenhouse gas calculations. Applications go to the contact listed, Anna Brockschnieder, and German-language communication is expected.

The focus is almost entirely on the environmental side of ESG, and specifically on the certification that keeps biogas and bio-LNG recognised as sustainable under renewable energy rules. That means the greenhouse gas calculations for the plants and for customers, the sustainability evidence that proves feedstock and production meet the required standards, and the audits that verify all of it. Because EnviTec also markets climate-neutral fuels for transport, the role touches the sustainability criteria that fuel buyers and regulators rely on. Governance shows up in the form of documentation standards and audit readiness rather than board-level reporting. Social topics and broader corporate ESG strategy are less central here, since this is an operational compliance and certification position inside a renewable energy business. There is also room to shape the group's own processes. The posting mentions supporting the further development and optimisation of sustainability processes, so the person in this seat could gradually influence how the company handles certification across its plants and customer base.

One likely challenge is the gap between operational reality and documentation. Plant operators and technical colleagues produce the data, but the responsibility for turning it into audit-ready evidence sits with you, so you depend on others delivering on time and accurately. Chasing missing information across departments and external partners could test anyone's patience. Regulatory change is another. Sustainability criteria for biogas and renewable fuels shift over time, and keeping up with new requirements while running current certifications demands attention. Greenhouse gas calculations add their own complexity, since small differences in assumptions or input data can change the result and the certification outcome. The role also covers a growing base of plants and international markets, so scale is a factor. As EnviTec operates 87 own plants and works across 18 countries, the documentation load is substantial, and keeping processes consistent while staying organised and results-oriented, as the posting puts it, is the everyday balancing act.

A typical day likely splits between the screen and the phone. You could spend the morning updating sustainability evidence and certification records for a set of plants, checking that data in the documentation matches what the operators reported, and working through greenhouse gas calculations in Excel. Later you might join a call with an internal technical department or a certification body to clarify a requirement or chase a missing document. The rhythm follows the audit calendar. In quiet periods the focus shifts to keeping documentation tidy and improving internal processes; closer to a certification deadline the days fill with coordination between plant operators, certifiers and colleagues. There may also be occasional travel to sites or audits, though the weekly home-office day suggests much of the desk work can be done remotely.

Growth in this role likely comes through deepening expertise rather than a fixed ladder. Certification and greenhouse gas calculation skills are specialised, and someone who masters them could take on more complex plants, international markets or the design of the company's sustainability processes. The posting's mention of supporting process optimisation suggests a path toward shaping how certification is done across the group. EnviTec's size and reach create lateral options. With activities spanning plant construction, biological and technical services, operational management, bio-LNG and even wind and solar projects, a person in this seat could move into adjacent areas over time. The company's international presence across 18 countries also opens the possibility of working on cross-border certification questions. Because sustainability requirements for renewable fuels keep developing, the knowledge gained here stays relevant. Someone who becomes the internal expert on certification and THG could find themselves with increasing visibility in a business where proving sustainability is central to revenue.

The most frequent external contacts are likely the certification bodies and auditors who assess the plants and the sustainability evidence. You would be the person they come to for documents, clarifications and follow-up, so the relationship needs to be cooperative and precise. Plant operators form the other main external group, since they supply much of the operational data the certifications rest on. Internally, the role sits between several departments. You would work with technical teams who know how the plants actually run, with commercial colleagues who deal with customers, and possibly with colleagues in agriculture given the feedstock side of biogas. The posting explicitly names close coordination with internal specialist departments, which suggests you act as a connector rather than working in isolation. There may also be contact with customers whose own biogas or fuel needs certification. In those cases you would help them understand what evidence is required and how the process works. Managing several stakeholder groups with different priorities at once is a defining feature of the job.
