The CFO’s five key contributions to sustainability
From driving accurate reporting to fostering long-term value, CFOs can exert a profound influence on their organizations’ approach to sustainability.
1. Ensuring ESG data quality for elevated performance
“Finance has a unique role to play in ensuring data quality,” Blondiaux explains. “Just as we ensure the integrity of financial data, we must apply the same discipline to ESG data.” The stakes are high. With the CSRD mandating assurance of key ESG disclosures, the credibility of a company’s sustainability metrics can make or break stakeholder trust.
Blondiaux also emphasizes the significance of nonfinancial metrics in defining performance. “Traditionally, performance was assessed using metrics such as cash flow and earnings before interest, taxes, depreciation and amortization,” he says. “However, moving forward, it must increasingly incorporate non-financial reporting data.”
“I am working with finance teams to take ownership of this shift, so that business reviews evaluate not only financial performance – top line and bottom line – but also social KPIs, value chain metrics, and environmental indicators, with equal weight. As a finance team, we are uniquely positioned to integrate these metrics into our processes.”
2. Motivating finance talent and leading with conviction
The expanded scope of the CFO role offers a more dynamic and appealing career path. “Let’s be honest, what’s been new for the finance function in the past decade?” Blondiaux asks. “Sustainability, in particular, offers a broader scope that makes the role more engaging and impactful.” He emphasizes the importance of leading by example. “At Chanel, we have nearly 1,000 finance professionals globally,” he explains.
“It’s crucial to communicate with conviction and passion. Without those, it’s challenging to bring people on board. To embed this requires time and persistence. For instance, despite addressing sustainability topics consistently over the past two to three years, they are not yet fully ingrained in our team. Repetition and clear messaging from leadership, particularly in finance, are essential to ensuring alignment and understanding across the organization.”
3. Fostering effective collaboration
Strong collaboration between finance and sustainability teams is essential. However, as teams become involved in each other’s traditional remit, agreeing and respecting lines of demarcation will be crucial. For example, sustainability teams may be wary of finance trying to set their targets for them. Clarifying roles and responsibilities can help build a productive partnership. At Chanel, the division is clear.
“It’s the responsibility of the sustainability team to set targets and deliver the programs to achieve them,” Blondiaux explains. “However, finance plays a critical role in ensuring clear and accurate reporting, defining measurable targets, and tracking performance and progress. The roles are highly complementary, and I firmly believe that robust reporting is essential to the overall success of these initiatives.”
4. Maintaining focus on long-term goals
Blondiaux believes that long-term delivery of targets should take precedence over short-term cost considerations. “The priority is meeting the targets we’ve committed to, regardless of the cost,” he says.
The role of the board is critical in maintaining this focus. “If boards prioritize only financial metrics like EBITDA, climate goals will inevitably take a back seat,” he warns. “Climate numbers cannot be secondary.”
5. Building the value case for sustainability
CFOs are instrumental in quantifying the value of sustainability initiatives, Blondiaux explains: “When evaluating investments such as a new factory, it’s no longer just about financial returns. You need to measure the carbon impact.”
This dual approach embeds sustainability considerations into every major decision. “It’s about integrating financial and non-financial metrics into a combined value case,” he confirms.
