The strength of METREX is its direct contact with practitioners and decision makers in some 50 metropolitan regions and areas across Europe and three in other continents.

METREX focusses on regions and areas that experience the Metropolitan Dimension in the field of transportation, housing, socio-economic development and environmental issues.

Not all METREX members are formally organised as a region, but they all collaborate with their neighbouring local authorities as they realise the issues they face transcend local authority borders.

This collaboration can enhance funding and budgets and their position on the European and/or global level, which often translates to better outcomes for citizens, businesses and institutions.

The growing number of METREX members not only demonstrates the need to exchange and learn, but also reflects the growing awareness amongst local authorities of the benefits of collaboration.
