You will support Grenergy’s ESG team with the day-to-day work behind its sustainability reporting: gathering and reviewing internal indicators, preparing responses to ESG rating questionnaires and information requests, and helping coordinate internal and external audits. You also take part in carbon footprint calculations, decarbonisation tracking and the follow-up of the company’s sustainability strategy objectives.
Grenergy develops and operates solar plants and has built a significant battery storage business, so the data you help assemble feeds directly into how a listed renewable energy producer explains its environmental and social performance to investors and raters. The ESG angle here is concrete: turning operational figures from solar and storage assets into credible, verifiable disclosure.
This suits someone who is early in their sustainability career, comfortable with Excel and PowerPoint, fluent in English, and genuinely curious about climate, biodiversity and non-financial risk. You will be working across departments and international teams, so a collaborative, detail-oriented mindset matters more than years of experience.
Job FAQs
What are the main missions and responsibilities of this role?
The core of this role is data and coordination. You will collect, review and analyse internal sustainability indicators that feed Grenergy's reports and its answers to ESG rating questionnaires and ad hoc information requests. That means chasing numbers across departments, checking them for consistency and packaging them in a form that auditors and raters can verify.
Beyond reporting, you support the preparation and follow-up of internal and external audits and verification processes, and you help track the objectives, commitments and initiatives that sit inside Grenergy's sustainability strategy. Part of the work involves calculating the corporate carbon footprint and following decarbonisation and environmental management initiatives, which for a solar and battery developer connects directly to the emissions profile of construction and operations.
Finally, you coordinate with different departments and international teams, and you prepare presentations, reports and other materials for the ESG department. The role is broad by design: it exposes you to the full reporting cycle rather than a single slice of it.
Key learning opportunities for this job
You can expect hands-on exposure to the mechanics of ESG reporting at a listed company: how indicators are defined, collected, reviewed and assured, and how they map to frameworks and rating methodologies. Because Grenergy responds to ESG ratings and information requests, you will learn how investor-facing assessments are built and what evidence they demand.
On the technical side, the carbon footprint and decarbonisation work offers practical grounding in greenhouse gas accounting and environmental management, applied to solar plants and battery storage rather than a generic office footprint. Audit and verification support builds a skill that is transferable across any sustainability function.
The international coordination element is an underrated learning opportunity: working with teams across Europe, the US and Latin America develops your ability to align data practices across jurisdictions with different reporting expectations. For an early-career professional, that breadth is hard to get elsewhere.
How does the ideal candidate look like (experience, skills)?
The posting is open on academic background: environmental sciences, engineering, biology, business administration, economics or humanities degrees are all accepted. What matters more is a demonstrated interest in sustainability, climate change, biodiversity, non-financial risk and sustainable finance. A master's in sustainability or a related field such as sustainable finance or non-financial risk management is a plus, not a requirement.
Language and tools are the practical filters. A very high level of English is expected, since the ESG team works with international colleagues and external raters. Intermediate MS Office skills, mainly Excel and PowerPoint, are the baseline for the reporting and presentation work.
On soft skills, the role rewards precision, patience with data and comfort coordinating across teams. Given the trainee framing, curiosity and willingness to learn likely weigh more than prior professional experience in ESG.
Advice to stand out and make a successful application
Because this is a trainee role, your application should signal that you understand what ESG reporting actually involves rather than just expressing enthusiasm for sustainability. If you have any coursework, thesis or project touching carbon footprinting, non-financial reporting, ESG ratings or sustainable finance, make it visible and describe concretely what data you handled and what you produced.
Grenergy is a listed renewable energy producer with solar and battery storage assets, so tailoring matters. Showing that you understand why a developer with a storage business faces specific reporting questions (emissions from construction, land use, biodiversity, supply chain) will read as more credible than generic climate statements. If your English is strong, let the quality of your written materials demonstrate it.
In interview, be ready to talk about how you would approach collecting a sustainability indicator across departments: who you would ask, how you would check the number, and how you would document it for an auditor. That kind of practical reasoning fits the role better than broad statements about saving the planet.
What aspects of the company's sustainability is this role likely to focus on?
This role sits at the reporting and data end of Grenergy's sustainability work, so the focus is likely on the indicators that underpin its ESG disclosures and rating responses. That includes environmental metrics tied to solar plant development and operation, and increasingly to battery storage projects, which bring their own supply chain and lifecycle considerations.
The carbon footprint and decarbonisation responsibilities suggest a focus on greenhouse gas accounting across the company's activities, alongside environmental management initiatives. For a company that positions storage as a way to deliver constant clean energy, being able to evidence the emissions profile of that model is central.
Governance and social dimensions are also in scope through the audit, verification and non-financial risk elements. Responding to ESG ratings and information requests means the role touches how Grenergy presents its policies, targets and performance to investors, which ties directly to its status as a listed company.
What are the main challenges someone in this role might face?
The main challenge is likely the data itself. Sustainability indicators for a multinational with projects across three regions often sit with different teams, in different formats and at different levels of maturity. Getting consistent, audit-ready numbers means a lot of follow-up and reconciliation, and progress can depend on colleagues who have other priorities.
A second challenge is the reporting calendar. ESG ratings questionnaires, audit cycles and verification processes come with fixed deadlines, and as a trainee you may be supporting several of them at once. Balancing routine data work with the less predictable requests that arrive from raters or internal stakeholders requires good prioritisation.
Finally, there is a learning curve around standards and frameworks. If you are early in your career, the vocabulary of non-financial risk, sustainable finance and assurance can feel dense at first, and you will be absorbing it while producing real deliverables.
How could a typical day look like for someone in this position?
A typical day would likely mix desk work and coordination. You might spend the morning updating or reviewing an indicator spreadsheet, checking figures against previous periods and preparing a summary for an ESG rating response or an internal report. Excel and PowerPoint would be constant companions.
Interactions with other departments are central. You could be emailing or meeting colleagues in finance, operations, environment or legal to request data or clarify a figure, and coordinating with international teams in different time zones. During audit or verification periods, the rhythm shifts towards gathering evidence and answering auditor questions.
The role also includes supporting the sustainability strategy tracking, so some days involve preparing presentations or materials for the ESG team rather than pure data work. Variability comes mainly from the reporting calendar and from ad hoc information requests.
What are the opportunities for professional growth and development in this role?
As a trainee position inside a listed company's ESG team, this role offers a strong foundation for a career in sustainability reporting, ESG analysis or non-financial risk. The exposure to ratings, audits and verification processes is exactly the experience that later roles in corporate ESG, consulting or sustainable finance tend to ask for.
Within Grenergy, strong performance could open paths towards a permanent analyst or specialist position in the ESG or sustainability function, or lateral moves into areas such as environmental management, investor relations or project development where sustainability data is increasingly relevant. The company's presence across Europe, the US and Latin America may also create opportunities to work on international projects.
Growth here depends partly on how much you take ownership of the data and processes you touch. Someone who improves a reporting workflow or builds a reliable indicator tracker becomes visible quickly in a lean ESG team.
The main stakeholders you might be interacting with
Your closest stakeholders would be the ESG team itself, including the people who own the reporting and strategy work and who would guide your day-to-day tasks. You would also interact regularly with colleagues in finance, legal, environment and operations, since sustainability indicators are drawn from across the business.
Externally, the role touches auditors and verification bodies during assurance processes, and indirectly the ESG rating agencies and investors whose questionnaires and information requests the team responds to. These interactions are usually managed through the team rather than directly, but your work feeds them.
Given Grenergy's international footprint, you can expect to coordinate with teams in Europe, the United States and Latin America. That means adapting to different working styles and time zones, and building relationships with people you may rarely meet in person.
