Short name for Eco-Management and Audit Scheme, also known as EU Eco-Audit or Eco-Audit. EMAS was developed by the EU and is a joint environmental management and audit scheme for organisations that want to improve their environmental performance. EMAS is one of the so-called "New environmental policy instruments" (NEPI). The great strength of EMAS lies in the measurement and publication of the environmental impact of the company in order to improve it in terms of sustainable development. This works both in terms of pure environmental protection and from the point of view of improving eco-efficiency, which can increase economic and ecological performance, for example by reducing superfluous material flows (eco-efficiency).
