It is not only with the Ukraine war and Russia's halt in the supply of energy sources that it has become clear how important energy-saving measures are. Reducing energy consumption also brings Switzerland closer to its climate targets.

To reach the net-zero target by 2050, investments of around $100 trillion are needed. This is equivalent to about 15% of total global investment over the next 30 years.

The overuse of natural resources is pushing the Earth's environmental systems to their limits. However, the transition to efficient resource use is a long process. Switzerland is also working on this.
