Guy has over 30 years' experience in management consulting, in biodiversity governance (EU, UK) and in frontline nature conservation.


He directed the €2.2M H2020 project We Value Nature (2019-2022) for the Institute of Chartered Accountants in England and Wales, led the business interface for the €6.5m UK Valuing Nature Programme (2014-2020), and led the business interface of the €10m EU FP7 project OpenNESS (2012-2017).

In 2019-20, he organised for the UK Natural Environment Research Council (NERC) a series of business round tables (land management, infrastructure, finance sectors) and a major conference at the Royal Society on a Natural Asset Research and Innovation Agenda in Support of Business and Policy.

Appointed by the UK Secretary of State for Environment, Food and Rural Affairs as a Member and then Deputy Chair, of the UK Joint Nature Conservation Committee (2009-16), he nurtured a strategic shift to a natural capital approach in JNCC statutory advice to UK Government and devolved administrations.

Guy led the Innovation Workstream for the EU Business @ Biodiversity Platform (2014-2019).

He led the research team underpinning the UK Ecosystem Markets Task Force (2013-14) and research for Defra on the design of biodiversity offset markets (2013-14), informing development of the provision for biodiversity net gain in the Environment Act 2021.

As lead for biodiversity policy at the European Commission (2002-07), Guy fostered an EU policy shift to engage the private sector in the delivery of biodiversity targets. He was instrumental in the launch and resourcing of The Economics of Ecosystems and Biodiversity (TEEB), precursor to the Capitals Coalition, the Dasgupta Review and the Task Force on Nature-Related Financial Disclosures (TNFD).

As a director at ERM (1998-2002) he built a £1M net p.a. consultancy practice on natural resources and biodiversity with international development clients (EU, DFID, SIDA, World Bank, GEF).

Guy is Honorary Professorial Fellow, Pentland Centre for Sustainability in Business, University of Lancaster and Fellow, UK Centre for Ecology and Hydrology. He was previously Honorary Research Associate, Environmental Change Institute, University of Oxford (2011-21).
