Maxfield works at the intersection of sustainability, procurement, and system change, helping turn ambition into operating reality across global supply chains.

As Global Head of Sustainability at the Chartered Institute of Procurement & Supply (CIPS), Maxfield leads the organisation’s global agenda to set the benchmark for sustainable procurement and supply. His focus is on strengthening the standards, skills, and incentives that shape how procurement decisions are made—from the classroom to the boardroom—so the profession is equipped to deliver consistently and at scale.

Procurement is no longer a support function. It is one of the most powerful levers organisations have to manage risk, meet climate and nature commitments, uphold human rights, and create long-term value. When procurement works, sustainability becomes integral to everyday commercial decisions rather than an add-on.

What drives Maxfield's work is a simple belief: sustainability only delivers when it becomes embedded in professional norms, commercial decisions, and institutional expectations — creating the conditions for a just transition to a net-zero, nature-positive economy. His focus is on building the institutions, professions, and markets that make sustainable value creation the default, not the exception.

Maxfield is particularly interested in how professions evolve, how standards shape behaviour, and how organisations build the capability to deliver value and operate ethically in a rapidly changing landscape.

Maxfield is a regular speaker on sustainable procurement, professional standards, and value creation, engaging with leaders across business, policy, and the wider sustainability ecosystem.

With over 20 years of experience bridging sustainability and procurement, he has helped organisations collectively turn ambitious goals into tangible action and progress by supporting the people and professionals involved (often equally passionate & frustrated) to make change happen.
