BERN - The Federal Council published its updated climate framework on Wednesday, proposing a 55 percent reduction in greenhouse gas emissions by 2035 compared with 1990 levels. The plan replaces interim targets that expired at the end of last year and adds a funding mechanism designed to win support from cantons that rely on industrial output.

Under the proposal, cantons that exceed their assigned reduction benchmarks would receive additional federal grants for public transport and building retrofits. Cantons that fall short would see a proportional cut in climate-related subsidies. Energy minister Albert Rosti called the approach fair and measurable during a press briefing outside the Bundeshaus.

Party lines drawn

The centre parties signalled cautious backing, noting that the framework aligns with Switzerland's commitments under the Paris Agreement. The Swiss People's Party rejected the targets outright, arguing that stricter limits would burden manufacturing in cantons such as Aargau and Solothurn.

We cannot ask factory workers in Olten to pay for Geneva's tram expansion, SVP parliamentarian Thomas Aeschi said in a statement.

The Green Liberals countered that delaying action would cost more later, pointing to flood and slope damage in the Alps. SP co-president Cedric Wermuth said cantons need numbers they can put in a budget.

What happens next

The National Council opened its autumn session on 14 September. Climate policy is scheduled for a first reading on 18 September, with a final vote expected before the Christmas break. Observers say the outcome may hinge on whether the Centre party holds its position or seeks amendments on agricultural exemptions.

The framework arrives as UN climate negotiators meet in Geneva. It also meets a housing stock that is only slowly leaving oil, according to new heat-pump figures. Tighter building standards could accelerate renovations in Zurich.
