This web-based Clearinghouse was established by THE PEP Steering Committee as a tool for disseminating information and good practises and for capacity building on the priority areas, including integration of environmental and health aspects into transport policy, demand side management and modal shift, urban transport and cross-cutting issues. The PEP Clearing House provides a range of policy, legal and scientific information, including good practices, on issues relevant to the transport, health and environment. It showcases links and user-friendly search mechanisms. It also aims to provide interactive facilities for the exchange of views and good practices on The PEP implementation thereby representing a reference base and main platform for all actors and organs within the framework of The PEP. THE PEP puts particular focus on the specific problems and needs of the Eastern Europe, Caucasus and Central Asia (EECCA) and South-Eastern European countries, as well as to ecologically particularly sensitive areas of the region.
