https://www.swissinfo.ch/eng/politics/vote-results--june-13-2021-switzerland-co2-pesticides/46631396Results are in - a Swiss voter can elaborate further, but the three environmental referendums (a popular initiative on clean drinking water and healthy food, a popular initiative on banning pesticides and a vote on the CO2 act) were all rejected, while the votes on the COVID-19 Act and the Counter-Terrorism Provisions were carried. The CO2 act vote was the closest.
Perhaps unsurprisingly, Basel-Stadt only voted with the rest of the country on the COVID-19 Act, but was on the losing side on the other four.
