We examine whether the adoption of global voluntary environmental management systems - United Nations Global Compact and ISO 14001 - lead to more effective environmental performance.

Possible reasons for conflicting results are the influence of observable and unobservable factors that affect environmental performance as well as the use of different measures of environmental performance indicators.
