Working under the CSR Director, you will oversee the technical execution of the French firm’s sustainability strategy. You will lead the transition toward CSRD compliance by coordinating cross-departmental data collection, managing carbon footprint assessments, and drafting official reports. Your work will also extend to operationalizing climate plans through the SBTi framework while managing transversal topics like responsible purchasing.

This role is critical because it turns regulatory constraints into a strategic advantage for a major global consulting player. By ensuring the integrity of ESG data and climate commitments, you help maintain the firm’s credibility in a sector that is increasingly defined by radical transparency and rigorous decarbonization standards. You will be at the heart of the group’s internal transformation, ensuring their own environmental house is in order.

This suits someone who enjoys technical data management just as much as stakeholder coordination. You should be a regulatory expert with a passion for climate science and the ability to influence diverse internal teams in a fast-paced corporate environment.

Job FAQs

What are the main missions and responsibilities of this role?

You will be responsible for the end-to-end preparation of the CSRD report, which involves identifying key stakeholders, coordinating internal data contributions, and consolidating technical information for the final deliverables. Your role also involves leading carbon data collection campaigns to complete the firm's overall carbon footprint analysis. Additionally, you will support the SBTi climate transition plan by collaborating with internal experts to define and deploy actionable goals. You will also manage transversal CSR projects, such as implementing responsible purchasing guidelines and digital sustainability initiatives across the organization. Finally, you will handle external queries by responding to ESG questionnaires from clients and extra-financial rating agencies like EcoVadis and CDP. Keeping a firm pulse on regulatory updates is essential to ensure the firm's compliance and continuous improvement in its sustainability performance.

Key learning opportunities for this job

This position offers a deep dive into the CSRD framework, providing hands-on experience with one of the most comprehensive sustainability regulations in Europe. You will gain expertise in aligning corporate targets with the Science Based Targets initiative (SBTi), which is the gold standard for corporate climate action. You will also have the chance to be trained in or facilitate recognized awareness workshops like the Climate Fresk and 2 Tonnes. Exposure to a high-level auditing environment will sharpen your analytical skills and provide a unique perspective on how professional services firms integrate ESG into their core operations.

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

The ideal candidate holds a Master's degree in Sustainable Development or CSR and brings at least two years of experience in extra-financial reporting and carbon footprints. You must possess a strong understanding of current French and European regulations to navigate the complexities resulting from the Green Deal. Soft skills are just as important as technical ones; you need to be professional, diplomatic, and comfortable coordinating diverse teams across a large organization. Since Mazars operates internationally, fluency in English is necessary for collaborating with global counterparts and understanding international standards.

Advice to stand out and make a successful application

To stand out, demonstrate your technical proficiency in carbon accounting tools and reporting frameworks like CSRD or GRI. Mention specific instances where you have managed cross-departmental projects, as this role requires significant internal diplomacy and the ability to get busy partners to prioritize data delivery. During interviews, align your personal values with the firm's culture of entrepreneurial spirit and individual singularity. Showing that you can take initiative and lead projects independently while remaining a team player will be highly valued by the CSR Director.

What aspects of the company's sustainability is this role likely to focus on?

The primary focus is regulatory compliance and data-driven sustainability management. You will be ensuring that the firm's environmental claims are backed by rigorous data, particularly regarding the decarbonization of professional services through the SBTi framework. There is also a strong social and governance component, as the role involves responding to ESG ratings that evaluate how the firm treats its people and manages its suppliers. Your work on responsible purchasing and digital sustainability will directly influence the firm's indirect environmental impact.

What are the main challenges someone in this role might face?

One of the chief challenges will be the coordination of data from various departments that might not see reporting as their primary priority. You will need to build strong internal relationships to ensure timely and accurate information flow for the CSRD requirements. Balancing the technical rigor of carbon calculations with the need for clear, strategic communication can also be difficult. You must be able to translate complex regulatory requirements into actionable steps for non-expert colleagues across the audit and tax departments.

How could a typical day look like for someone in this position?

A typical day might begin with a stakeholder meeting to track the progress of data collection for the annual report, followed by an analytical deep dive into carbon emission data for the French offices. You might spend the afternoon drafting sections of the climate transition plan or responding to a client's ESG questionnaire. You could also find yourself leading an internal Climate Fresk workshop to engage employees, or attending a networking event with partners like the UN Global Compact or C3D to stay updated on best practices and industry trends.

What are the opportunities for professional growth and development in this role?

This role provides high visibility as the CSRD is a top priority for executive leadership. Successfully delivering the first few reports under this new regulation could position you as a key subject matter expert within the firm or the wider professional services sector. You could eventually move into a strategic CSR management role or specialize further in climate finance or ESG consulting for clients, leveraging your internal experience of running these processes for a global leader.

The main stakeholders you might be interacting with

Your closest collaborator will be the CSR Director, but you will act as a bridge between many internal departments, including Finance, HR, Legal, and Procurement. You will interact with these teams constantly to gather data and implement transversal projects. Externally, you will engage with rating agencies like EcoVadis, industry networks such as the C3D, and potentially clients who require detailed ESG information during the RFP process. You may also coordinate with third-party verifiers during the auditing of your sustainability reports.
