We need support to take action

Lake Geneva is in good health, providing us with an exceptional quality of life and a host of benefits: drinking water, swimming, boating, tourism, various lake-related professions, etc.

However, we must remain vigilant, as we know that Lake Geneva is not immune to potential pollution such as macro-waste, micro-plastics, chemical products and micro-pollutants, nor to degradation linked to the loss of biodiversity, climate change and demographic pressure.

You too can help protect the waters of Lake Geneva. Your commitment will enable us to continue our actions over the long term and ensure that future generations can also benefit from this unique heritage!
