Environmental, Social, and Governance (ESG) concerns aren’t just nice-to-have—they’re central to how companies operate and grow.
As people, from investors to employees, pay closer attention to how businesses impact the world, companies are stepping up their efforts in sustainability reporting. And right at the heart of this transformation is a crucial new role: the ESG controller.
This role helps bring structure, consistency, and trust to how companies measure and report their environmental and social impact, similar to how a financial controller manages financial data.
The Rise of ESG in Corporate Strategy
So what exactly is ESG? It’s short for Environmental, Social, and Governance. In simple terms, it’s how a company handles things like climate impact, how it treats people, and how transparent and accountable its leadership is.
Not long ago, ESG reporting was mostly driven by regulations. But now, everyone, investors, customers, and employees, is looking for real proof that companies are doing the right thing. That means organizations need reliable systems and roles in place to manage this properly.
Enter the ESG controller.
The job has grown to be just as important as financial roles. In fact, more than 95% of the world’s leading companies now release sustainability reports, proving that sustainability isn’t just a trend anymore; it’s the new standard.
ESG Controller Responsibilities: Driving ESG Integration
The ESG controller plays a key role in making sure a company’s sustainability data is accurate, complete, and aligned with both internal goals and external expectations.
Data Management and Validation
They gather sustainability data from different departments—HR, operations, compliance—and make sure it’s clean, accurate, and auditable. Think of them as the quality control lead for ESG data.
Framework Alignment
They ensure the company’s ESG reports align with recognized standards like GRI, SASB, and TCFD, so the information is consistent and comparable with others in the industry.
Cross-Functional Collaboration
They don’t work in a silo. ESG controllers coordinate with many teams, translating complex sustainability data into clear, reportable metrics that meet international and industry-specific standards.
Performance Monitoring
From carbon emissions to workforce diversity and social impact, they keep track of key non-financial metrics and ensure these are reported accurately, often using indicators like PAI (Principal Adverse Impacts).
Simply put, the ESG controller is part analyst, part strategist. They help connect a company’s sustainability goals with real, measurable outcomes.
ESG Governance and Oversight: Where Controllers Fit In
ESG governance is all about making sure there are clear structures and processes in place to handle sustainability issues. And the ESG controller plays a big part in making that happen.
Here’s how they support governance and oversight:
- Ensuring Transparency: ESG controllers treat environmental and social data with the same rigor as financial data, which builds trust with investors and regulators.
- Facilitating Compliance: With new rules like the Corporate Sustainability Reporting Directive (CSRD) in the EU, ESG controllers help ensure companies stay compliant.
- Supporting Board-Level Oversight: ESG controllers provide key insights to board committees, helping leadership make better-informed decisions around sustainability.
Thanks to their role, ESG data becomes more reliable and easier for leadership teams to use in decision-making.
Key ESG Leadership Positions and How They Work Together
The ESG controller isn’t working in isolation—they’re part of a broader team of sustainability leaders, including:
- Chief Sustainability Officer (CSO): Focuses on the big-picture strategy for sustainability.
- Head of ESG: Often handles day-to-day coordination of ESG initiatives across departments.
- ESG Committee Chair: Leads discussions on ESG priorities and tracks overall progress.
Most ESG controllers report to the Chief Financial Officer (CFO), which makes sense considering the role’s emphasis on data integrity and compliance. This reporting structure also helps embed ESG metrics into financial systems and decision-making.
What sets great ESG controllers apart is their ability to go beyond the numbers. They support meaningful change by helping leadership make smarter, sustainability-focused choices backed by solid data.
ESG Reporting Roles and Duties: Building Credible Disclosures
A big part of the ESG controller’s job is to make sure reports are not only accurate but also credible and useful.
Here’s how they do it:
- Consolidating Data: They pull together ESG data from internal teams and external sources to build a complete picture of performance.
- Ensuring Quality: Controllers check for consistency, reliability, and transparency, using well-established data collection practices.
- Implementing Frameworks: They apply frameworks like GRI, SASB, and TCFD, each of which serves different reporting needs, from broad societal impacts to financial materiality and climate risk.
- Staying Current: ESG reporting is evolving quickly. Controllers keep up with changes and update systems to stay compliant.
With so many eyes on ESG performance these days, high-quality reporting isn’t optional—it’s essential.
ESG Roles in Corporate Sustainability: Controllers as Change Agents
Beyond reports and metrics, ESG controllers play a powerful role in driving real, lasting change in how a company operates.
Here’s how they influence corporate sustainability:
- Goal Setting and Tracking: They help define clear, measurable targets—like cutting emissions or improving diversity—and make sure progress is tracked properly.
- Supporting the Transition: With access to reliable data, they identify gaps and help teams create action plans for improvement.
- Shaping Strategy: Their insights guide investment decisions, risk management, and brand strategies, making sure sustainability is baked into every major move.
They aren’t just data handlers—they’re part of the team shaping the company’s future.
ESG Consultants: External Expertise for ESG Success
While many companies are building ESG expertise internally, ESG consultants can provide valuable outside help. They assist with strategy development, risk assessments, data collection, and stakeholder communications.
Consultants are especially useful for:
- Navigating new or complex regulations
- Building ESG frameworks from scratch
- Benchmarking performance against competitors
Together with internal teams, they ensure the company’s ESG efforts are both compliant and impactful.
The Strategic Value of ESG Controllers
The ESG controller has gone from a behind-the-scenes role to one of strategic importance. As businesses become more serious about sustainability, the need for reliable ESG data and reporting is only growing.
These professionals help companies build trust, stay compliant, and make smart, responsible decisions. And that makes the ESG controller a key player in aligning business success with positive social and environmental impact.
In a world where being transparent and accountable is more important than ever, ESG controllers are helping companies walk the talk, turning bold sustainability goals into measurable, reportable outcomes.
