What is a fractional Chief Sustainability Officer?

Sustainability, otherwise referred to as ESG, has become more and more important in business. ESG stands for Environment, Social, and Governance. This is intended to cover the different aspects of being a sustainable business. Another common term is the triple bottom line: people, planet, and profit. 

A fractional sustainability officer is a professional who can take charge of your company's sustainability initiatives, partner with your CFO to ensure alignment, or when it is necessary to get specific skills or a more senior experience level on board. 

A fractional Sustainability Manager can start immediately and bring with him/her experience, confident leadership, and the ability to implement the needed changes.


What does a fractional chief sustainability officer do?

Fractional sustainability managers help organizations navigate the change they're going through. The exact activities will largely depend on the circumstances within the team. In essence, fractional sustainability professionals have the experience and skills to take over from the previous in-house managers. Alternatively, they can lead a team that might lack the necessary skills or experience. Fractional sustainability officers bridge the gap that the company has identified, whether that is due to unexpected leave, a turnaround, or other circumstances that lead to this need for support. 

This work is often done by experienced sustainability professionals. With Dazzle, we give you access to the best freelance sustainability talent. In this overview, we will talk you through:

Qualifications and skills of fractional Chief Sustainability Officers

Typically, fractional CSOs will have worked with many organizations throughout the years. It's not untypical to have led full sustainability or ESG departments in the past. That means that an experienced fractional CSO can hit the ground running very fast, without a long onboarding period compared to a full-time employee. On our platform, we have a wide range of freelancers, to be able to match your organization, budget, and ambition level. 

Our recommendation would always be to work with senior professionals in the case of fractional support


Senior sustainability freelancers (with 7+ years of experience as a sustainability professional) can support you completely from becoming compliant to moving beyond basic requirements. They can act as Chief Sustainability Officers as a service to lead the sustainability efforts from the ESG strategy formation all the way up to publishing your annual sustainability report. 

Why would you work with a fractional Chief Sustainability Officer?

A Fractional Chief Sustainability Officer is a safe and cost-effective choice when your business is facing a change, a leave of absence, or other situations when you need to level up your sustainability strategy. A fractional CSO can also step in and support the existing team in a specific sustainability project or initiative.

If you have a vacancy you are unable to fill, you can engage fractional sustainability support in a short time with rapid results and implement changes during the time you recruit a permanent employee.


When is it the right choice to consider a fractional Chief Sustainability Officer?

  • When launching a (new) sustainability strategy
  • When implementing a change in sustainability strategy
  • To implement structures and processes
  • In case of anxiety/lack of leadership
  • If there is a need for support in specific sustainability projects
  • In the event of a vacancy, maternity leave or sick leave

Time pressure and urgency

Recruiting employees for a full-time position in your sustainability team can be a timely process. With Dazzle, you can get started in as little as 48 hours. Simply book a discovery call, complete the scoping form and we'll match you to the best fractional professional. When reports are due,  deadlines are lurking around the corner, and data collection is delaying your progress, working with a fractional CSO can fast-track your actions and help you bridge the gap in your team. 

Understaffed ESG department

The beauty and challenge of sustainability is that it is an extremely broad topic, with more and more sub-topics. Especially in organizations that don't have a fully staffed ESG department, it's almost impossible to expertly cover every single specialty. Sustainability freelancers are a convenient solution to bridge the skills gap that inevitably exists within your organization and get expert advice or implementation support in peak times. 

Skill gaps and topic-specific expertise

Some extremely complex legislation might be coming your way, which could fall outside of the comfort zone of your core sustainability team. We also regularly see sustainability being covered by HR, Marketing, or Operational departments. Especially senior sustainability advisors can deliver much-needed specialist expertise, for example for complex biodiversity scans, LCAs, or reporting requirements. 

Local expertise 

If the ESG department has no expertise in a local market but needs to comply with local regulations, it's difficult to find a sustainability advisor to support those cross-border activities. Experienced fractional sustainability professionals can supply guidance for local legislation, and reporting requirements, but also culturally sensitive advice on engaging employees in your sustainability efforts.

Benefits of working with a fractional Chief Sustainability Officer


Instead of hiring someone full-time, working with freelancers allows you to get support only for the hours you really need. 


Dazzle can match you with a freelancer that fits within your budget. However, it is important to consider that fractional sustainability managers are often senior professionals.
