Starting in 2021, the Federal Council plans to replace the existing promotion policy by a steering system, in order to achieve the goals of the Energy Strategy 2050 and to reduce greenhouse gas emissions. In the present project, ETH Zurich researchers have investigated to what extent this change would impair Switzerland's economic strength. They discovered that the country would benefit from a tax reform leading to environmental taxes, as the levies on electricity and fuel would encourage innovation. This would result in a more competitive economy and thus growth, provided the earnings are redistributed among the taxpayers in a suitable form. The prosperity of the population would decrease slightly. However, this monetary approach does not take into account the quality of life gained through a cleaner environment. For their study, the researchers have generated a theoretical model of the impact of such a tax reform. On the basis of these considerations, they then calculated the consequences using a computer model calibrated to Swiss conditions.
