As Head of Environmental Management with the Environment Agency, Dave developed and facilitated its environmental strategy. Dave is now is an independent sustainability consultant working in the public and private sectors. He supports organisations in developing and implementing sustainability and environmental strategies, and environmental management systems. As an advocate of “cyclical thinking”, his approach is to primarily focus on the potential for organisations to achieve significant economic and environmental gains through improvements in resource use efficiency. Dave has produced environmental management guides and procedures covering procurement, land management and estates, premises, estates, project management and auditing. He incorporated Sustainable Development issues into the Government’s Estates and Premises Management Guides. Dave has written articles on sustainability and presented at international seminars.

Dave has carried out a wide range of audits, including a food supply chain for a multi-national retailer, a leading property developer, buildings and operational functions, and produced supporting audit guides and procedures. He has carried out a sustainability appraisal for DEFRA of the Government’s food procurement strategy and of a region’s waste management strategy, identifying fresh issues and opportunities. The application of sustainability and cyclical thinking in his recent report “Achieving the UK’s Climate Change Commitments and the Efficiency of the Food Cycle” has generated considerable interest by highlighting eco-efficiency opportunities within the “food chain”. Dave has supported a leading NGO in developing their sustainable land management strategy.

He is an associate lecturer at the National School of Government and at various universities presenting on sustainable development and government policy appraisal, and environmental management of estates, premises, buildings and facilities.

Dave also runs a “zero input” smallholding producing sustainable beef and mutton from traditional local rare breeds. The system approach centres around the application of cyclical thinking, and identifying and replenishing the specific trace element deficiencies in the soil.
