Chief Sustainability Officer as a Service (CSOaaS)

CSOaaS provides a fractional Chief Sustainability Officer who is an experienced sustainability leader who works with your company on a part-time or project basis, rather than as a full-time employee.
Think of it like having a “shared” sustainability expert - someone who brings senior-level experience and strategic thinking but only for the time and scope your business actually needs.
How it Works
-
Flexible Engagement: Instead of hiring a full-time CSO (which can be costly and unnecessary for smaller or growing companies), you engage utilise CSOaaS for a few days a month, or for specific projects such as designing a climate strategy or helping with ESG investor readiness.
-
Tailored to Your Needs: The CSO becomes an extension of your leadership team, helping you identify priorities whether that’s reducing emissions, improving reporting, developing sustainability goals, or embedding ESG into operations.
-
Short or Long-Term: The arrangement can last a few months (for example, to get you “green debt ready” or support an IPO) or longer-term (to guide ongoing sustainability efforts until a full-time hire makes sense).
Benefits of Using CSOaaS
In Simple Terms
Using CSOaaS is like having a sustainability leader on demand: someone to guide your company’s sustainability journey strategically and efficiently, helping you do good for the planet and your bottom line.
Immediate Impact
The CSO can quickly assess where you are, create a roadmap, and start implementing practical actions.
Flexible and Scalable
As your company's sustainability needs evolve, you can increase or decrease the level of support.
Expertise without the Full-time Cost
You get access to senior-level sustainability leadership, often someone who has worked in large corporations or across industries, without paying a full executive salary and benefits.
Objective Perspective
Because they work across different companies, these fractional CSOs bring fresh insights and proven best practices from other sectors.
