As a working student in Sustainability Assurance, you’ll get deeply involved in the certification and monitoring of bio-fuels. You’ll help the team translate greenhouse-gas reduction regulations into precise internal reports and balances, taking ownership of data quality in certificate trading and supporting the administrative and contractual side of sustainability documentation.

This mandate matters for Europe’s energy transition, since VAROPreem, as one of the largest producers of renewable fuels, plays a key role in decarbonizing the transport sector. You’ll work right at the intersection of traditional energy supply and the scaling of sustainable alternatives, and your CO2-savings analyses will provide the transparency needed to make progress toward climate-neutral solutions in Germany measurable and credible.

This suits someone who is studying business administration or environmental economics and wants to combine a structured way of working with a strong interest in data analysis and regulatory questions in the energy sector.

Job FAQs

What are the main missions and responsibilities of this role?

The primary focus is ensuring the integrity of sustainability certifications for bio-fuels. You will assist in preparing bio-balances and documentation required for both internal environmental audits and external regulatory reporting. Beyond administrative support, you will conduct detailed data analyses regarding CO2 reduction targets and the trading of emission certificates. This involves reviewing contracts against legal templates to ensure all sustainable fuel transactions meet strict German and European compliance standards.

Key learning opportunities for this job

You will gain first-hand experience in the complex landscape of renewable energy regulations and GHG quotas (THG-Quote). This role offers a deep dive into how large-scale energy companies manage the transition from fossil fuels to sustainable alternatives. Additionally, you will strengthen your technical skills in database management and professional Excel reporting within an international corporate environment. Exposure to cross-departmental projects will also provide insights into the logistics and market entry strategies of renewable fuels.

How does the ideal candidate look like (experience, skills)?

The ideal candidate is currently enrolled in a degree program such as Environmental Economics, Business Administration, or a related field. You should have a strong interest in the energy transition and a high degree of comfort working with numbers and complex datasets. Proficiency in MS Office, particularly Excel and Outlook, is essential. Since you will be handling legal texts and reporting, professional-level fluency in both German and English is required to communicate effectively with local stakeholders and international teams.

Advice to stand out and make a successful application

To stand out, demonstrate an understanding of the RED II directive or the German 'Treibhausgasminderungsquote' (THG-Quote), as these are central to the role. Mentioning any previous experience with sustainability reporting standards or auditing processes will show your technical readiness. Highlight your ability to work with high precision and detail. In the world of assurance, accuracy is more important than speed, so showcase examples from your studies or prior internships where you managed complex data without errors.

One significant challenge will be maintaining data accuracy in a fast-paced environment where regulatory requirements frequently evolve. Balancing the administrative tasks like contract management with more complex analytical projects requires excellent time management.

You will need to be proactive in asking questions and staying updated on new sustainability legislation.
