Sustainability is essential for businesses, influencing investor decisions, customer trust, and regulatory compliance. Many companies, especially small to mid-sized ones, understand the importance of ESG but struggle with the cost and resources needed to hire a full-time Chief Sustainability Officer.

Sustainability and ESG leadership have traditionally been overseen by dedicated executives or shared among teams. However, with the rapid pace of change, companies often need specialized expertise on demand. A practical alternative is hiring a Fractional Chief Sustainability Officer. A fractional CSO provides expert sustainability leadership on a flexible, interim basis, making ESG expertise accessible without the expense of a full-time executive salary.

This article clearly explains the role of a fractional chief sustainability officer, highlights their primary responsibilities, and helps you recognize when hiring one can benefit your organisation.

 

Understanding the role of a fractional chief sustainability officer

What is a fractional CSO?

A fractional executive is an experienced professional hired on an interim or temporary basis to provide specialised skills. Businesses choose fractional leaders because they offer senior-level expertise without the full-time cost. Fractional executives originally became popular in finance, HR, and technology roles, but now they are increasingly used in sustainability due to growing ESG demands.

Fractional CSOs typically assist companies in swiftly tackling specific sustainability issues, including regulatory compliance, ESG reporting requirements, and managing stakeholder expectations. They bring extensive industry experience and can effectively navigate complex ESG scenarios.

Core responsibilities of a fractional chief sustainability officer

Fractional CSOs help handle several critical responsibilities:

  • ESG strategy development: Creating and implementing sustainability strategies aligned with the company’s business objectives.
  • Regulatory compliance: Managing ESG-related regulations, such as those from the EU’s CSRD or the SEC’s climate disclosure rules.
  • Reporting and disclosures: Preparing accurate ESG reports using frameworks like GRI, SASB, or TCFD.
  • Stakeholder engagement: Communicating effectively with stakeholders, including investors, employees, and customers, about sustainability practices.
  • Supply chain sustainability: Evaluating and improving environmental and social impacts throughout the company’s supply chain.

When should companies consider hiring a fractional chief sustainability officer?

Navigating regulatory requirements

Organisations facing new or changing ESG regulations often benefit from hiring a fractional chief sustainability officer. Regulations like Europe’s Corporate Sustainability Reporting Directive (CSRD) and the U.S. Securities and Exchange Commission’s (SEC) climate disclosure rules can create complex compliance demands. An interim CSO quickly identifies gaps, aligns strategies, and ensures timely adherence without long-term costs.

Business transitions and sustainability alignment

Major transitions, such as mergers, acquisitions, IPOs, or significant internal restructuring, usually require a focused approach to ESG. During these changes, fractional CSOs provide swift expertise to integrate sustainability effectively and reduce potential risks. They streamline processes and communicate ESG strategies to stakeholders.

Increased ESG scrutiny from stakeholders

Growing ESG expectations from investors, customers, and regulators require businesses to demonstrate credible and transparent sustainability commitments. A fractional chief sustainability officer helps your company manage these increased demands efficiently, improving investor relations, enhancing customer trust, and ensuring regulatory compliance.

Benefits of hiring a fractional chief sustainability officer

Immediate access to senior-level ESG expertise

Hiring a fractional chief sustainability officer gives your organisation instant access to senior-level ESG knowledge without the long-term cost of a full-time executive. This enables your organisation to rapidly develop and implement sustainability strategies, navigate complex regulatory requirements, and achieve meaningful ESG progress. 

Cost efficiency and flexibility

Fractional CSOs offer significant cost advantages compared to full-time sustainability executives. Companies can control expenses by engaging interim leaders only as needed, whether for specific projects or periodic advisory roles. This flexibility ensures that your ESG efforts scale efficiently according to your business needs and budget..

Fresh perspectives and innovation

An external fractional chief sustainability officer brings unbiased, innovative perspectives to your sustainability initiatives. Their diverse experiences across industries enable them to introduce creative solutions and effectively address ESG challenges within your organisation. Their external viewpoint can help drive internal change more rapidly and effectively.

 

Challenges companies might face and how to overcome them

Integration with existing teams

However, bringing an interim CSO into your organisation might create initial integration challenges. Existing teams could be uncertain about roles, responsibilities, or reporting structures. Clear communication from leadership, combined with well-defined objectives, can effectively address these issues. Scheduling routine meetings and collaborative planning sessions guarantees the fractional chief sustainability officer smoothly integrates into your team, fostering effective teamwork and alignment.

Ensuring long-term ESG commitment

A potential challenge is ensuring sustainability initiatives continue effectively after the fractional CSO’s assignment ends. To maintain momentum, fractional CSOs often establish clear, structured ESG frameworks and train internal teams to manage ongoing activities. Promoting internal champions who advocate sustainability helps embed these practices into your organizational culture for lasting impact. Following the recourse of a fractional CSO, other organisations may choose to hire a chief sustainability officer on a long-term basis to ensure continuity and success in the sustainability strategy and integration.
