Then there are additional operating costs of around 14 billion francs in total. Reaching the net-zero target eliminates costs for importing fossil energies which results in sav- ings of around 50 billion francs.85 The cumulative additional costs over the period 2020 to 2050 amount to 73 billion francs in total.

Even without the net-zero target, additional investments in the energy system of 1400 billion francs are required by 2050. With the net-zero target by 2050, the investment requirement increases by 109 billion francs in total or by eight per cent.
