The global climate has had natural fluctuations over periods of time ranging from a several years to millions of years. Since the beginning of industrialization the composition of the atmosphere has increasingly changed due to greenhouse gas emissions. This man-made development amplifies the natural greenhouse effect and leads to a noticeable change in the climate.
Switzerland pursues an active policy on reducing greenhouse gases, thus contributing to the internationally agreed target of limiting global warming to considerably less than 2 °C, and ideally 1.5 °C. The CO2 Act focuses on reducing Switzerland’s domestic emissions.
More frequent heatwaves and dry periods, increasing natural hazards and changes to the diversity of fauna and flora – climate change is already having an impact on our environment today and will have an increasingly significant effect in future. Switzerland is committed to climate protection. In the Paris Agreement, it pledged to cut greenhouse gas emissions by 50% until 2030 compared to 1990 levels. Because, however, global warming can be restricted to 1.5 °C in the best case, adapting to the effects of climate change is becoming more and more important. This platform provides current information about the adaptations being undertaken by the Swiss Confederation, cantons and municipalities.
The Swiss Parliament is currently discussing a total revision of the CO2 Act that sets out objectives and tools for reducing greenhouse gas emissions in the period up to 2030. At the same time, it is vital to prepare for longer-term developments beyond 2030. To this end, on 28 August 2019 the Federal Council decided that Switzerland should reduce its greenhouse gas emissions to net zero by 2050.
Greenhouse gas emissions do not respect national borders. Because climate change has had serious repercussions for Switzerland with its mountain ecosystem, a globally coordinated course of action for this Alpine country is essential. Switzerland is strongly committed to climate protection at an international level.
