A majority of Swiss citizens have voted in favor of a bill aimed at introducing new climate measures to sharply curb the rich Alpine nation’s greenhouse gas emissions. Sunday's referendum was sparked by a campaign by scientists and environmentalists to save Switzerland’s iconic glaciers, which are melting away at an alarming rate. Campaigners initially proposed even more ambitious measures but later backed a government plan that requires Switzerland to achieve “net zero” emissions by 2050. The nationalist Swiss People’s Party, which had demanded the popular vote, had claimed the measures would cause electricity prices to rise.
