METREX is an established network of over 50 metropolitan regions and areas in Europe. They contribute the metropolitan dimension on a European scale, addressing the challenges faced in climate adaptation, energy production and consumption, productivity, competitiveness, migration and inequality, and digitalisation. Metropolitan Regions and Areas are best positioned to tackle these challenges by bringing together urban and rural areas and leveraging each other's strengths.

For over 25 years, METREX has played a crucial role in shaping policies, programs, and projects at a European scale. They work closely with European institutions, research communities, governmental organizations, and other networks. METREX hosts regular events and meetings for members through expert and network groups, online METREXmonthly events, and bi-annual conferences.

METREX supports Metropolitan Regions and Areas by enabling integrated thinking, accelerating urgent transitions, contributing to a common policy framework, contributing to effective policies, and sharing knowledge and experience on urban and rural themes. Their approach is based on being 'Living Labs', investing in pilots and research across their territories to find workable solutions with maximum impact.
