Environmental Protection


CERN is committed to limiting the impact of the Organization’s activities on the environment. Within the HSE Unit, this goal is achieved mainly by:

  • integrating pollution prevention, waste minimisation and conservation of resources into existing and planned activities in order to limit their environmental impact (environmental prevention and awareness);
  • carrying out an environmental monitoring programme, updated yearly and agreed upon with the Host States' authorities, aimed at measuring the physicochemical and radiological impact the Organization’s activities (environmental monitoring);
  • informing the Host States' authorities (France and Switzerland) of the results of the environmental monitoring programme and of any other relevant environmental matters.
