The amended constitutional clause demands that the cantonal and local authorities take steps to slow down climate change and work towards climate neutrality by 2050.
Sunday’s vote was in response to public climate protests launched in 2019 and pressure notably by the Green Party.
Bern is only the second of the country’s 26 cantons – after Geneva -to include climate goals in their cantonal constitution. Several other cantons are currently drafting amendments to their constitutions.
Similar moves are underway at a national level to include zero CO2 emissions as a goal into the Swiss constitution.
Three months ago, Swiss voters rejected a CO2 tax, including price hikes for petrol and other fuels. The reform was aimed at cutting by half the country’s CO2 emissions by 2030 in line with the Paris Climate Agreement.
