In Oslo, one of the most ambitious projects in the world to switch public transport to electricity is being implemented quickly: by 2028, all city and suburban routes are expected to become zero-emission. Already now, 85% of bus services in the city rely on electric buses, and in just six years, CO₂ emissions from buses have been cut by 95%. This has made the air noticeably cleaner, and the city quieter and more comfortable for residents.
Oslo’s experience is unique not only because such a rapid transition has rarely happened elsewhere, but also because of how the city tackled winter problems. In January 2023, electric buses began to discharge faster than usual due to severe frosts, but engineers responded by introducing CO₂ heat pumps. Residents are openly informed about the difficulties and involved in a dialogue—support that helps not only build acceptance, but also improve technologies faster.
The city has also started pilot projects in which a subscription to public transport is included in residents’ utility payments through housing cooperatives: this increases loyalty to public transport and makes it easier to leave the private car behind.
