Purpose – This paper aims to examine the implementation of the Eco-Management and Audit Scheme (EMAS) in a non-profit, small-to-medium sized-enterprise (SME) in the UK. Design/methodology/approach – A four-year participatory action research study is made upon knowledge transfer partnerships between the University of the West of England and the Royal Bath and West Society. Findings – Through the adoption of EMAS, the organisation was able to identify operational improvements as well as make significant efforts to improve its environmental performance, reducing its carbon footprint by 30 tCO2e per annum and gaining new business. Research limitations/implications – The study is made upon a single not-for-profit organisation in the UK. Practical implications – It presents the costs, benefits and challenges that the organisation faced. Techniques that were used to successfully manage the environmental management systems (EMS) development are also discussed. The investigation identifies deficiencies in the materials that are provided to support companies that are seeking EMAS certification. To improve the uptake of these EMS and assist companies in their successful pursuit of ISO 14001 and EMAS, this supporting documentation requires enhancement. Originality/value – There has been relatively little empirical research around the development and benefits of organisational EMS. Even less has focussed upon the specific constraints and opportunities that face non-profit organisations when implementing EMAS. This paper addresses this gap, identifying its costs and tangible benefits.
