Chief Sustainability Officer Recruitment

Chief Sustainability Officer Recruitment

Exec Capital provides senior Chief Sustainability Officer (CSO) recruitment for UK firms across listed, private, PE-backed and family-controlled businesses. The CSO role has evolved from a peripheral compliance function into a substantive C-suite appointment over the past decade, with strong CSOs now leading material commercial strategy alongside reporting and stakeholder dimensions. UK CSO senior hiring is shaped by the substantial UK ESG reporting framework (TCFD, transition plans, sustainability disclosure standards), the net zero commitments embedded in major UK firms’ strategic plans, the substantive supply chain due diligence dimension, and a candidate market that draws from a tight pool of senior leaders with both substantive ESG depth and credible commercial track records.

Our practice covers UK senior CSO appointments across listed and pre-IPO firms with substantial ESG reporting obligations, PE-backed firms calibrating sustainability to value-creation theses, and private mid-market firms responding to customer and stakeholder expectations on sustainability. Every mandate is led personally by Adrian Lawrence FCA.

What the Chief Sustainability Officer role covers

The substantive CSO role splits across four dimensions, with relative weighting varying by firm.

Strategy and commercial integration. The substantive dimension that distinguishes strong CSO appointments. Sustainability strategy as part of broader commercial strategy — product portfolio implications, customer expectations, market positioning, supply chain implications.

Reporting and disclosure. Compliance with UK ESG reporting frameworks (TCFD, sustainability disclosure standards, transition plans), and (for listed firms) substantive engagement with shareholder advisory bodies and ESG ratings agencies.

Operational delivery. Decarbonisation programmes, scope 1, 2 and 3 emissions reduction, supply chain due diligence, water and waste management.

Stakeholder and external engagement. Investor engagement on ESG, customer-led sustainability requirements, regulator engagement, and broader public-policy dimensions.

The candidate pool

The UK senior CSO candidate pool is genuinely tight at the senior end. Five pools recur. Sitting CSOs at peer firms. Most direct pool. Step-up candidates from Heads of Sustainability roles. Natural growth pool. Senior environmental and ESG specialists from consulting practices. Big Four sustainability practices, specialist ESG advisory firms. Senior leaders from regulatory and policy backgrounds. Particularly relevant for firms in regulated sectors. Cross-functional senior leaders with substantive prior sustainability work. Operations, supply chain, or strategy backgrounds with sustainability dimensions.

How we work

We run CSO searches on a retained basis, with engagement running through to the candidate’s first day in role. Adrian leads every CSO mandate personally — from the brief, through market mapping and engagement, to offer negotiation and onboarding work that follows.
