Duncan’s career has seen him move between the corporate and non-profit sectors. He has an honours degree in forestry and first worked for a variety of forest companies; including spending nine years with Shell Forestry, in London, Chile and Uruguay. He worked in planning and operational roles setting up world scale greenfield forest and pulpmill projects.

He then spent almost ten years with WWF International, in the Forests for Life Programme and as the Director responsible for WWF’s global conservation work on energy, water, forests, species, oceans and policy. Duncan helped build WWF’s capability to work with business, involving both collaborative partnerships and campaigning approaches.

In 2010 Duncan joined Nestlé, where he worked to embed sustainability across the different functions, businesses and markets. He led and supported the development of programmes on responsible sourcing, rural development & livelihoods, climate, biodiversity, plastic packaging, food systems, and new ways of measuring societal value creation. An important aspect of the role was developing collaboration with governments and stakeholders (NGOs, investors, and corporate platforms).
