Chargé de mission bas carbone

This role sits at the heart of Eiffage's low-carbon strategy, within the Group Sustainability and Cross-functional Innovation Department that reports directly to the CEO. Day to day, you would help formalise and roll out the group's low-carbon action plan, track actions and indicators across the different business lines, and support teams as they manage their own carbon trajectories. Part of the work is also watching regulation and sourcing solutions or start-ups that could accelerate decarbonisation. Carbon accounting and reporting are a significant slice of the job. You would contribute to the calculation of greenhouse gas emissions (BEGES), help improve the group's methodology, and check the consistency of quantitative data used in the sustainability report and extra-financial ratings. You'd also be in contact with the independent third-party body that certifies the group's non-financial reporting. A third strand is knowledge sharing and internal animation: identifying and promoting best practices, drafting reference documents and digital content, running newsletters and webinars, and supporting environmental training for employees. Finally, you might support tender responses and provide technical or regulatory expertise to teams that request it, both in France and internationally.

You would deepen your mastery of carbon accounting at group scale, not just applying a methodology, but helping evolve it across a sprawling, multi-business organisation. The exposure to BEGES, extra-financial ratings and third-party assurance is a strong foundation if you're aiming toward ESG reporting or CSRD-type roles later. Because Eiffage spans construction, real estate, energy systems, civil engineering, metal, roads and concessions, you'd get a rare cross-sector view of how decarbonisation plays out differently depending on the activity. That kind of multi-business fluency is hard to build elsewhere. You would also develop regulatory watch skills on French and European environmental and energy-performance rules. On the softer side, the internal animation, training design and newsletter/webinar work would strengthen your ability to influence without authority, a skill that matters enormously in sustainability roles where you rarely control the teams you need to move. If you're interested in PowerBI, there's likely room to apply it to indicator development, though it isn't the core of the role.

Eiffage is looking for someone with a Bac+5 in environmental science or general engineering with an environment focus, plus a first successful experience specifically in the low-carbon field. That experience matters: this isn't a graduate entry role, and the team will expect you to already understand carbon accounting fundamentals and the French regulatory environment on energy and carbon performance. Project management basics are explicitly requested, which signals that you'll be juggling multiple workstreams rather than executing one narrow task. Strong written French is essential for the reference documents, newsletters and reports, and professional English is needed because the role reaches international subsidiaries and the group's global operations. Meeting facilitation skills are also flagged, which points to a role where you'll be in front of people regularly. Valued extras include energy performance expertise, PowerBI proficiency, and, perhaps most importantly, a collaborative temperament. The ability to synthesise complex information concisely will set candidates apart, given how much of this job involves translating technical carbon data for non-specialist audiences.

Lead with your carbon expertise in concrete terms: which methodologies you've applied (BEGES, GHG Protocol, SBTi), what scope of emissions you've calculated, and in what kind of organisation. Eiffage is a large, decentralised industrial group, so any experience working across multiple sites or business units will resonate more than a purely consulting-side profile. Your cover letter should show you understand the specific tension in this role: it sits between data rigour and human influence. You're not just crunching numbers, you're persuading construction, roads and concessions teams to change how they work. A letter that acknowledges this dual nature, with an example of a time you moved a team toward a climate target, will stand out. Before interview, get familiar with Eiffage's three environmental strategies (low-carbon, circular economy, biodiversity) and its main business lines. Knowing the difference between what a road division and a concessions division can decarbonise shows genuine preparation. Also be ready to discuss how you'd handle a business unit that is resistant to a group target: that scenario is almost inevitable in this kind of role.

The core focus is decarbonisation. Eiffage has committed to reducing the environmental impact of its activities, and this role is explicitly attached to the low-carbon and circular economy pole. That means carbon trajectory management, emission calculations and the low-carbon action plan are central. Circular economy (materials reuse, waste reduction in construction) is the close companion priority of this same pole. Beyond climate, the role touches responsible procurement, working with the group's purchasing department, and feeds into the broader sustainability report and extra-financial ratings. So governance and transparency dimensions are present too, even if the environmental angle dominates. Biodiversity is a third group strategy, though this role is less directly attached to it. Because Eiffage operates across construction, infrastructure, energy and concessions, the sustainability work here is unusually broad in scope. Decarbonising a roads business, a building contractor and a motorway concessionaire requires very different levers, and supporting all of them is part of what makes this position distinctive.

The biggest challenge is likely influence without direct authority. You'd be supporting business lines that have their own operational pressures, margins and timelines, and convincing a construction or roads team to prioritise carbon reduction when they're focused on delivery is genuinely hard. Progress often depends on relationships and credibility rather than formal power. A second challenge is data quality and consistency across a large, decentralised group with international subsidiaries. Gathering reliable quantitative data, checking it and improving methodology year after year requires patience and rigour, and the pace can feel slow when you're working toward ambitious climate targets. Finally, there's the inherent tension between group-level ambition and the operational reality of heavy industry. Construction is a hard-to-abate sector, and some emissions reductions depend on technology, suppliers or regulation beyond your control. Managing that gap, staying useful and credible while acknowledging the limits, is part of the job's difficulty.

Mornings might involve working through carbon data, checking figures submitted by a business unit, refining a calculation method, or preparing inputs for the group's BEGES and sustainability reporting. You could be on a call with the RSE team or with an international subsidiary, clarifying a data point or agreeing on an indicator definition. Documentation and report drafting often fill these quieter hours. The middle of the day might bring a meeting with one of the group's businesses (construction, roads, energy systems) to review their carbon trajectory or follow up on an action from the low-carbon plan. You might be presenting, facilitating, or simply listening and noting where support is needed. Occasionally you'd contribute to a tender response with a technical or regulatory angle. Afternoons could swing toward knowledge sharing and animation: drafting a newsletter, preparing a webinar, updating reference documents, or improving environmental training materials. No two days look the same, and the mix of analytical, relational and editorial work is part of the role's texture.

Given that this position sits within a department reporting to the CEO, visibility is high. Strong performance would likely open doors to more senior roles within the sustainability department, potentially leading a thematic pole (low-carbon, circular economy) or moving toward broader ESG strategy and reporting leadership. Because the role interfaces with so many business lines and international subsidiaries, it builds a network across the group that can be a springboard toward operational sustainability roles embedded in a specific business. Moving from a central function into a business unit, or the reverse, is a common and valued trajectory in large industrial groups like Eiffage. The reporting and assurance exposure also positions you well for the growing market of CSRD and ESG reporting roles, which are in high demand. If you're interested in the regulatory and financial side of sustainability, the BEGES and extra-financial rating work here is directly transferable.

You'd work most closely with the low-carbon and circular economy pole within the DDDIT, plus the adjacent RSE team that owns the sustainability report and extra-financial ratings. The purchasing department is also a key counterpart given the responsible procurement angle, and the cross-functional innovation team connects to the innovation promotion part of the role. Across the group, your main relationships would be with the different business lines (construction, real estate, energy systems, civil engineering, metal, roads and concessions) both in France and internationally. These teams are the ones implementing the low-carbon plan, so your day-to-day influence runs through them. You'd also interact with the independent third-party body that certifies the group's non-financial reporting. Externally, you might engage with solution providers, start-ups and suppliers as part of regulatory watch and sourcing, and occasionally with tender teams where your expertise feeds into bid responses. The role is genuinely cross-functional rather than confined to a single department.
