Limiting our impact on the environment

CERN’s fourth safety objective for 2012 concerns the reduction of the environmental impact of noise and energy consumption associated with CERN's activities.


In order to continue to reduce the impact of noise on our neighbours, the HSE Unit is coordinating measures to reduce noise in the environment at all the LHC and SPS points, and on the Meyrin and Prévessin sites. If you are aware of a high-intensity noise that could disturb those living and working close to our sites, you can contact the HSE Unit. And most important of all, please take this potential nuisance into account when you're planning new projects. The HSE Unit is there to help you.

The other aspect of our environmental target for the year is to optimise CERN's energy consumption. We can achieve this by limiting the energy consumption of facilities right from the design stage - from small components to large installations - and by using renewable energies even on a small scale. If you have any questions or suggestions relating to energy, please contact the Energy Issues Coordinator, Helfried Burkhart.

When you're planning a new project, think about energy recycling and about reducing noise in the environment.

The HSE Unit will be happy to answer any questions you may have. Contact us at
