The drive towards greener transport is also reflected in the creation of low-emission zones, where the most polluting vehicles have limited access or face high charges for driving. These initiatives are aimed at reducing air pollution and improving the quality of life for residents.

Another of London's strengths is its commitment to bicycle mobility. The city has a robust bike-sharing system, which has facilitated the use of this clean and healthy mode of transport. Bikeways have been expanded in recent years, connecting more areas and encouraging greater adoption of bicycles as an alternative to motorized transport.

In terms of electric vehicle infrastructure, London has also excelled. The number of charging stations for such vehicles has grown substantially, making it easier for drivers to transition to more sustainable transport options. In addition, tax incentives for the purchase of electric vehicles have been an important tool in the city to promote their use and decrease reliance on traditional cars.

The study highlights the importance of air quality as a key criterion for assessing the level of “green transport”. London has implemented a number of environmental policies designed to reduce pollution levels, such as the Ultra Low Emission Zone (ULEZ), which restricts the access of highly polluting vehicles in the city center.

These types of policies have had a positive impact on air quality, reducing particulate pollutants and nitrogen dioxide levels, which has also contributed to improving public health. Encouraging the use of public transport and investing in sustainable mobility infrastructures have been key to achieving this progress.

Although London leads the ranking, other European cities have also shown significant progress in implementing sustainable transport. The ranking highlights Stockholm, Copenhagen and Berlin as other cities that have adopted green policies and technologies to improve their urban transport.

Stockholm, for example, has made a strong commitment to renewable energy in its public transport system, while Copenhagen is known for its excellent network of bicycle lanes and massive use of bicycles. Berlin, meanwhile, has made progress in electrifying its bus fleet and expanding pedestrian and car-free zones.

The Uswitch study highlights not only London's achievements, but also the challenges that Europe as a whole still faces in achieving truly sustainable transport. While significant progress has been made in reducing emissions and adopting clean technologies, many cities still rely heavily on fossil fuels and need to accelerate their transition to more environmentally friendly mobility models.

The results of this analysis reinforce the need for continued investment in green infrastructure, incentive policies and technology to reduce the environmental impact of urban transport in Europe. London stands as an example of how large cities can lead the way to a cleaner and more sustainable future.

This report is a reminder that the transition to greener mobility depends not only on technology, but also on a strong political and social commitment to change transport habits in the world's major cities.
