As a result of long delays, many environmental groups from France, Italy and Switzerland have worked together under the umbrella organisation, proMONT BLANC, to jointly raise concerns and to put pressure on national governments and the European Union to support and make quicker progress with World Heritage classification. In 2012 the organisation published a detailed assessment and supportive rationale into the state of the Mont Blanc application to be a World Heritage Site. ProMont Blanc also undertakes reviews of a suite of 24 environmental, 24 economic and 10 social indicators across 15 towns around the massif (seven French, five Italian and three Swiss), and monitors and reports on the effectiveness of measures intended to deliver sustainable development across the region.
