Air pollution in major cities in Spain and around the world is a serious problem. The main causes of this situation are the excessive number of vehicles on the road and emissions generated by industries. High traffic density, especially of older vehicles that do not comply with modern emissions regulations, has had a direct impact on air quality. Older vehicles are major contributors to pollution because their emissions control systems do not meet current standards. In response, Barcelona is taking measures to curb air pollution and has decided to ban vehicles registered less than 20 years ago from circulating during periods of high pollution . This measure, which affects vehicles without an environmental sticker, aims to reduce emissions and reach the air quality levels recommended by the World Health Organization (WHO), a challenge that is already beginning to bear fruit in several European cities.
Vehicles over 20 years old
All passenger cars registered before 1997 and vans registered before 1994 will be banned from driving on weekdays in the 40 municipalities of Barcelona starting January 1, 2019. This regulation applies to weekdays and will implement restrictions when pollution levels peak. The implementation of a Low Emission Zone (LEZ) in Barcelona aims to reduce traffic-related emissions by 30% within 15 years and by 10% within the next 5. These actions are part of a sustainability commitment by several entities, including the Barcelona City Council and the Barcelona Metropolitan Area (AMB).
Air quality as a primary concern
Air pollution is one of the biggest urban problems of our time. The measures adopted by Barcelona to ban the circulation of old vehicles are part of the efforts to comply with the air quality levels recommended by the WHO. These levels are essential to prevent chronic respiratory diseases and reduce premature deaths caused by pollution, which according to the WHO, increase year after year. At a legal level, the Climate Change and Energy Transition Law approved in 2021 reinforces Low Emission Zones in cities with more than 50,000 inhabitants. Old vehicles that do not have environmental labels (B, C, ECO or 0 emissions) are the most affected by these restrictions. However, certain exceptions are being considered for historic vehicles that do not circulate more than 30 days a year.
Anti-pollution measures in Barcelona
In Barcelona, local authorities have approved a protocol to reduce pollution levels. This protocol includes increased public transportation, awareness campaigns, and the promotion of less polluting vehicles. These measures will benefit more than 4,3 million people, who will be able to enjoy cleaner, healthier air. Low Emission Zones in Barcelona are an important step toward transforming the city into a more livable space. These zones are being implemented gradually and prohibit the circulation of polluting vehicles on weekdays between 7:00 a.m. and 20:00 p.m. In addition to increased public transportation, a change in public attitude is necessary . This includes promoting the use of sustainable means of transport, such as cycling or walking, especially on days with high pollution levels.
Improve and promote public transport
Another key point is the improvement of public transport. While Barcelona's transport network is efficient, adjustments must be made to make it more comfortable, accessible, and affordable, which could contribute to a decrease in the use of private vehicles. It is hoped that increased service frequency, extended operating hours, and a more accessible fare system will encourage more users to rely on public transport. Furthermore, authorities are considering new routes and flexible fares for staff who depend on public transport in high-emission zones. The local government has called on citizens to prioritize the use of non-polluting transport during periods of high pollution. Efforts to improve public transport are essential to facilitate restrictions on the circulation of older vehicles. However, public transport alone will not be enough without public awareness. For these measures to be truly effective, it is crucial that the population takes an active role by reducing their use of private transport and promoting sustainable mobility practices. The restrictions, along with the reinforcement of public transport, offer a dual opportunity: to improve air quality and transform the transport culture in Barcelona. These measures will not only improve air quality in the city but will also serve as a model for other major European cities facing similar challenges. The impact of Low Emission Zones and restrictions on older vehicles demonstrates Barcelona's commitment to mitigating climate change and protecting public health.
