Qualitative evaluation of three 'environmental management systems' in the New Zealand wine industry

The wine growing industry is increasingly important to the New Zealand economy and increasingly its marketing is associated with the country's 'clean and green' image. Over 60% of New Zealand's wine companies have adopted at least one of three main environmental management systems: Sustainable Winegrowing New Zealand, ISO 14001 and Bio-Gro. We undertook a qualitative, survey based, comparative evaluation of these systems within 15 wine companies. The key findings are that while each system appears to have its own strengths, in general, no one environmental management system is better than the other. However, implementation of an industry specific system, for example SWNZ, in combination with a generic process-based system, for example ISO 14001, aids in the development of a more sustainable wine industry.
