Over a century ago, the Swiss built a hydroelectric power plant at Lütschental on the river to generate electricity. Today, the Valais produces about 30% of the hydroelectric power in Switzerland and is a pioneer in this development.

Switzerland has, over the years, committed to sustainable policies to govern the use of natural resources. They incorporate Cleantech to implement various technologies, manufacturing processes, and services to help reduce emissions, recycling, renewable energy, water quality, and eco-friendly transport.

Many cities such as Zurich, Bern, and Geneva are also highly ranked for the quality of life mainly due to the contribution of environmental factors. In the cities, many water fountains flow with clean drinkable water, a unique feature. With the establishment of the Swisstainable program, many attractions, transports, hotels, and restaurants are also accredited to make it easy for visitors to seek out Swisstainable tours.

Green Educational Tour is developed by Kuoni Tumlare in conjunction with Switzerland Tourism for travel groups specifically to study and learn about the sustainable experience in Switzerland.
