Hi Kristyna and Welcome to MySwissAlps,
We are not an official government organization so I don't have any specific information.
Your best bet would be to go to the Swiss government website. Maybe there is someone there you can contact for this information?
A quick google search of Alps Sustainability turned up some links that may be useful and some PDF files of official reports on your topic.
