Fewer new cars, but hardly any climate benefit
In Switzerland, so few new cars are being purchased as has not been seen in decades. In 2025, only 233’737 new passenger cars registered – a historic low. At first glance, this development seems positive, because fewer new cars supposedly mean less resource consumption. But for climate protection, this development is problematic, because the reality on the streets tells a different story.
Instead of switching to new, more efficient vehicles, many Swiss men and women keep their old cars longer. And precisely here lies the problem: Ältere Fahrzeuge consume more fuel, emit significantly more CO₂ and also have fewer modern exhaust cleaning systems. While new cars – especially electric and hybrid vehicles – become increasingly climate-friendly, the existing vehicle fleet remains a large emitter.
In addition, technological advances only have an effect when they are also used. Engines are becoming more efficient, batteries more powerful and emissions lower, but without renewal of the vehicle fleet, this progress dissipates. At the same time, the maintenance costs of old cars increase, while safety systems such as emergency brake assistants or lane‑keeping aids are often missing.
Natürlich, economic uncertainties play a major role. Many people zögern because of high prices, rising living costs, and unclear political frameworks. Doch aus ökologischer perspective, stagnation is not a solution. Who länger with an outdated car fährt, saves short‑term money, but causes long‑term höhere environmental costs.
Therefore, new ways of thinking are needed. Carsharing, flexible mobility models and the targeted use of modern vehicles can help reduce emissions without each person having to own a car. Local offers already show that sustainable mobility can be everyday-friendly, affordable and climate-friendly.
In the end, the rule is: Not less mobility protects the climate, but better mobility.
