Swiss voters voted on Sunday to introduce a global minimum tax on businesses and a climate law that aims to cut fossil fuel use and reach zero emissions by 2050, public broadcaster SRF reported.

The results showed 79% of those who voted in Sunday’s national referendum backed raising the country’s business tax to the 15% global minimum rate from the current average minimum of 11%, while 59% supported the climate law.

In 2021, Switzerland joined almost 140 countries that signed up to an Organisation for Economic Cooperation and Development (OECD) deal to set a minimum tax rate for big companies, a move aimed at limiting the practice of shifting profits to low tax countries.

Even with the increase, Switzerland will still have one of the lowest corporate tax levels in the world, and the proposal, estimated to bring 2.5 billion Swiss francs ($2.80 billion) per year in additional revenue, has been backed by business groups, most political parties, and the general public.

The climate law, brought back in a modified form after it was rejected in 2021 as too costly, has stirred up more debate with those campaigning against it gaining traction in recent weeks.

Proponents say the law is the minimum the wealthy country needs to do to prove its commitment to fighting climate change while opponents from the right wing People’s Party say it will jeopardise energy security.

Greenpeace Switzerland welcomed the result of the referendum.

“This victory means that at last the goal of achieving net zero emissions will be anchored in law. That gives better security for planning ahead and allows our country to take the path toward an exit from fossil fuels,” said Georg Klingler, an expert on climate and energy at Greenpeace Switzerland.

“The result of the vote shows that the citizens of our country are committed to the aim of limiting global warming to 1.5 Celsius in order to preserve as much as possible our glaciers, our water reserves, our agriculture and our prosperity. I am very relieved to see that the lies disseminated by the opposite camp during the campaign did not sow the seed of doubt in people,” he added.

In Sunday’s referendum, voters also approved to extend some provisions of the country’s emergency COVID-19 law, required under Switzerland’s system of direct democracy, where legislation is put to the public vote.

Switzerland is home to the offices and headquarters of around 2,000 foreign companies, including Google as well as 200 Swiss multinationals, such as Nestle.

“No other country is going to have lower taxes either. We want the additional tax revenue to stay in the country, and be used to improve its attractiveness for businesses,” said Christian Frey, from Economiesuisse, a lobby group.
