Switzerland supports measures that promote infrastructure projects, public transport, drinking water supply systems, wastewater treatment, energy-efficient construction, the use of renewable energies, waste disposal, and nature conservation. Switzerland's commitment to the environment is also in its own interest, as environmental pollution does not stop at national borders.

Public transport

The expansion of public transport services improves both air quality and the quality of life.

Water and wastewater management

Drinking water supply systems play a key role in improving the quality of life. Improved wastewater treatment not only serves to protect water quality, but also people's health and well-being.

Energy efficiency and renewable energies

The use of renewable energies and energy-efficient construction not only reduces greenhouse gas emissions, but also electricity and heating costs.

Waste disposal

Environmentally sound remediation of contaminated sites dating to the period before EU accession is critical for the protection of the environment and public health.

Nature conservation and biodiversity

Exchanging experiences with Swiss organisations contributes to the protection of biodiversity and forests, and helps to promote eco-tourism and organic farming.
