As global regulations tighten and stakeholder expectations rise, sustainability has become a company-wide responsibility rather than the role of a single department. Organisations today must embed environmental, social, and governance (ESG) principles into every core function. This integrated approach strengthens corporate sustainability, reduces long-term risks, and positions businesses for competitive success in 2026 and beyond.

Below is an in-depth look at the 12 essential business functions that drive sustainability, and how each contributes to a holistic ESG strategy.

1. Finance: Embedding ESG into Budgets and Investments

Finance teams play a pivotal role by integrating sustainability considerations into budgeting, forecasting, and investment decisions. This includes assessing climate risks, prioritising low-carbon initiatives, and aligning capital allocation with long-term value creation. Strong financial stewardship enables sustainable growth and attracts ESG-focused investors.

2. Operations: Enhancing Efficiency and Reducing Environmental Impact

Operational sustainability focuses on reducing energy consumption, improving material efficiency, and minimising waste across processes. Companies that adopt cleaner technologies, optimise resource use, and streamline workflows strengthen both environmental performance and cost efficiency.

3. Procurement: Building Responsible and Ethical Supply Chains

Procurement departments drive sustainability by selecting suppliers that meet high environmental and ethical standards. Responsible sourcing, supplier audits, and sustainable procurement policies help organisations reduce Scope 3 emissions and ensure compliance with global ESG expectations.

4. Technology & IT: Powering ESG Reporting and Digital Transformation

Technology and IT functions are essential for building reliable ESG data systems, carbon tracking tools, and automated reporting platforms. As disclosure requirements expand under frameworks like ISSB, CSRD, and SECR, accurate and transparent digital reporting becomes a critical business necessity.

5. Legal & Compliance: Strengthening ESG Alignment and Regulatory Preparedness

The legal and compliance function ensures adherence to environmental policies, human rights regulations, anti-corruption laws, and sustainability-related reporting standards. Their work mitigates legal risks and enhances overall governance integrity.

6. Board & Governance: Setting the Organisation’s Sustainability Vision

Boards of directors shape the organisation’s long-term sustainability strategy by approving ESG policies, monitoring progress, and ensuring accountability across leadership teams. Strong ESG governance aligns company goals with global benchmarks and shareholder expectations.

7. Executive Leadership: Driving Commitment and Resource Allocation

Executives operationalise sustainability by allocating budgets, enabling cross-functional collaboration, and prioritising climate and social initiatives. Leadership commitment is a defining factor in the success of any ESG program.

8. Investor Relations: Communicating ESG Performance Transparently

Investor Relations teams bridge the gap between the company and its shareholders by communicating sustainability achievements, climate targets, and risk mitigation strategies. Transparent disclosure builds investor trust and strengthens market positioning.

9. Audit & Risk: Ensuring ESG Data Accuracy and Managing Emerging Risks

Audit and risk functions validate the accuracy and integrity of sustainability data. They also assess emerging risks such as climate impacts, supply chain vulnerabilities, and regulatory changes ensuring the organisation remains resilient in a rapidly evolving landscape.

10. HR & People: Advancing Diversity, Equity, and Employee Well-Being

Human Resources drives the social pillar of sustainability by promoting diversity, equity, inclusion (DEI), fair labor practices, and employee development. A strong people-first approach creates an ethical, inclusive, and high-performing workplace.

11. Marketing: Communicating ESG Commitments Credibly

Marketing teams amplify sustainability initiatives through transparent, accurate communication. By avoiding greenwashing and focusing on evidence-backed claims, they build trust with customers, communities, and stakeholders.

12. R&D / Innovation: Creating Sustainable Products and Future-Ready Solutions

Research and innovation teams lead the development of eco-friendly products, low-carbon technologies, sustainable materials, and circular solutions. Their work drives long-term competitiveness and positions the organisation as a leader in sustainable innovation.

Sustainability can no longer function in silos. Businesses that integrate ESG principles across every department are better positioned to:

Meet global regulatory standards
Reduce environmental and social risks
Improve operational efficiency
Strengthen investor and customer trust
Drive long-term resilience and profitability

As we move into 2026, the organisations that empower each business function to contribute to sustainability will be the ones that lead, adapt, and thrive.
