The European Property Federation (EPF) is lobbying the European Commission to introduce a unified energy certification system for the European Union. Michael MacBrien, director of Brussels-based lobby group EPF, believes a single EU-wide system is essential, given the cross-border nature of the property industry. 'Right now everybody has a difference certificate and we would like to go towards the situation where we are talking about the same thing,' MacBrien said in an interview with PropertyEU.
