11 Carbon-Neutral Cities in Europe Leading the Charge in Green Tourism

6. Oslo, Norway — Low-emission zones and fjord-friendly travel

Oslo’s climate planning includes low-emission zones and incentives for electrified public transport, which makes exploring the city and nearby fjords less carbon-intensive. The city has promoted electric buses and ferries to connect waterfront neighborhoods with outdoor recreation areas. Staying in the city center puts many attractions within walking distance, and eco-focused hotels often provide electric charging, locally sourced food, and clear waste policies. Visitors can book sustainable fjord cruises that use electric or hybrid vessels, and they can choose guided hiking or forest bathing trips that support conservation organizations. Oslo also encourages businesses to disclose climate measures, helping travelers identify lodgings and tour operators with measurable sustainability practices. For North American travelers planning a Scandinavian visit, pairing Oslo with regional rail travel reduces intra-country flights and supports lower-emission tourism options.
