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

5. Copenhagen, Denmark — The cycling capital with carbon-smart transport

Copenhagen’s long reputation for cycling and progressive transport policy makes it a natural pick for sustainable urban travel. The city’s cycling infrastructure and protected bike lanes are extensive, and many visitors choose e-bikes to cover more ground without emissions. Copenhagen has also expanded low-emission harbor buses and metro connections that reduce the need for cars in the center. For lodging, several hotels and design-forward guesthouses display green credentials like energy-efficient heating, waste reduction, and locally sourced food offerings. Bookable green experiences include guided bicycle architecture tours, culinary tours that showcase sustainable restaurants, and harbor swims or low-impact sailing trips operated by providers that follow environmental best practices. Copenhagen balances comfortable city life with practical options for low-carbon exploration, and it’s easy to design a trip that uses only public transport and cycles.
