With the Corporate Sustainability Reporting Directive (CSRD) reshaping how European companies approach sustainability, the CFO and CEO roles are converging around one central question: how do we build a business that is genuinely sustainable over the long term, not just compliant in the short term?

This article examines what long-term sustainability strategies look like for CEOs and CFOs navigating the current regulatory environment, and what distinguishes companies that treat sustainability as a strategic asset from those that treat it as a compliance obligation.

Sustainability as competitive advantage

The most forward-thinking CEOs are moving past the question of ‘do we have to report?’ and asking ‘what can we learn from our sustainability data?’ The GHG inventory, the double materiality assessment, the Scope 3 supplier data — these are not just compliance artefacts. They are windows into cost exposure, supply chain risk, customer demand, and long-term viability.

Companies that build genuine sustainability management capability — rather than just reporting infrastructure — will find that the data they collect drives better decisions: about energy efficiency, supplier selection, product design, and capital allocation.

The CFO’s role in long-term sustainability strategy

Sustainability strategy is increasingly a finance function. Three reasons:

1. CSRD brings sustainability into the annual report. Sustainability disclosures are now in the management report alongside financial statements, subject to the same limited assurance requirements. The CFO’s governance over financial reporting naturally extends to sustainability reporting.
2. Climate risk is financial risk. Physical climate risks (asset damage, supply chain disruption) and transition risks (regulatory carbon costs, market shifts) are balance sheet issues. Quantifying them requires the same financial modelling capabilities that CFOs already own.
3. ESG data drives capital markets. Institutional investors and lenders are integrating ESG data into investment and lending decisions. A CFO who doesn’t understand the company’s sustainability performance is increasingly flying blind.

What a long-term sustainability strategy looks like

The following elements distinguish a long-term sustainability strategy from a compliance program:

• Science-based targets: Emissions reductions tied to what climate science requires, not arbitrary percentages. SBTi validation is increasingly the credibility standard.
• Integrated reporting: Sustainability data sits alongside financial data in strategy and reporting processes, not in a parallel silo.
• Supply chain engagement: Scope 3 emissions require supplier engagement and collaboration, which builds supply chain resilience as well as reducing emissions.
• Cross-functional governance: Sustainability is not just the sustainability team’s problem. Finance, procurement, HR, and legal all have roles.
• Investor and lender alignment: Proactively communicating sustainability strategy and progress to capital market participants.

How the CSRD and Omnibus affect long-term strategy

The EU Omnibus proposal has narrowed CSRD scope and extended timelines. For companies still in scope, the core strategic logic hasn’t changed: building genuine sustainability management capability creates value beyond compliance. For companies that have dropped out of mandatory scope, the business case for sustainability management remains — customers, investors, and lenders are still asking for this data.
