Organization and objectives

In 1998 CLAN merged with the Netherlands Association of Environmental Professionals, in order to bring itself in a better position for more integrated approaches towards remaining environmental problems. CLAN was founded in 1983 as the successor of SICOM which, since 1970, had represented The Netherlands in IUAPPA. CLAN aims to disseminate knowledge of air pollution, be it of a technical nature or connected with policy, politics or control and to promote research to fill existing gaps in knowledge.

Since the merger with VVM, CLAN operates as one of the sections of this professional association and organises on the average two or three activities per year for VVM members and others in the field of air pollution and climate change.

Members of VVM-CLAN actively participate where possible in organising and developing international activities of other EFCA member associations and can draw for this on all 1800 members of VVM. CLAN hosted the 8th IUAPPA World Clean Air Congress in 1989 in The Hague and organized several activities in a European and global context, including the series of non-CO2 Greenhouse Gas symposia (NCGG,

The members of CLAN are individual members of VVM, who indicated interest in the area and subjects covered by the section. Their affiliations include research institutes; industry; central, provincial and local authorities; consultants; universities and schools. At present, about 500 individual VVM members are interested in CLAN activities on air pollution and about 600 in activities on climate change. 


CLAN achieves its objectives through:

  • organisation of national and  international conferences and of specialist meetings;
  • publications;
  • offering courses;
  • promotion of cooperation in research and of scientific acceptance of its results;
  • cooperation with other organisations which address environment-related topics.
