BRUSSELS/ZARAGOZA, (Unib Rashid) – The Spanish city of Zaragoza is placing noise management at the centre of its urban development strategy, adopting a proactive approach aimed at preventing noise pollution and creating quieter, healthier neighbourhoods through better city planning.

A member of the Green City Accord and a finalist for the 2028 European Green Capital title, Zaragoza is addressing noise pollution as a major environmental challenge by integrating acoustic health into urban development from the earliest planning stages.

At the heart of the initiative is the city’s Technical Guide for the Integration of Noise Management in City Planning, which forms a key part of its Noise Action Plan 2025–2029. The framework aims to move noise management beyond responding to existing problems towards preventing them through informed planning and design.

The guide recognises that land use, street layouts, building orientation and the location of green spaces all influence how sound travels through urban areas. By considering these factors before construction begins, the city aims to reduce future noise pollution and avoid costly corrective measures.

Under the framework, different parts of the city are classified according to their principal uses, including residential neighbourhoods, schools, industrial areas and natural spaces. Each category is assigned specific acoustic quality objectives to guide future development.

An important feature is the so-called “5 dB Rule,” under which new residential areas must be designed to achieve quieter conditions than those required under existing legal standards.

The framework also places greater emphasis on indoor acoustic comfort. Developers are required to demonstrate that new homes will provide healthy indoor noise levels, particularly in bedrooms, even where outdoor noise levels are high. Additional safeguards are required for developments near major transport infrastructure to address both airborne noise and structural vibrations.

Rather than relying exclusively on conventional noise barriers, Zaragoza is promoting urban design solutions that help limit the spread of sound. These include positioning buildings to protect quieter spaces, using green areas as natural buffers and favouring landscaped earth embankments over concrete walls where feasible.

For neighbourhoods already experiencing excessive noise, the city has identified five Special Acoustic Protection Zones, known by their Spanish abbreviation, ZPAEs. These areas are intended to benefit from targeted action plans that progressively improve acoustic conditions while allowing urban life and economic activity to continue.

Protecting public health through better planning

The initiative reflects growing recognition of the effects environmental noise can have on public health and quality of life. Noise exposure can contribute to sleep disturbance, cardiovascular problems and reduced cognitive performance, making the design of healthier urban environments an important planning priority.

The new framework also places responsibility on private developers to demonstrate that proposed projects comply with acoustic standards. Where additional protection is necessary, developers may also be required to finance measures to safeguard future residents.

By incorporating noise considerations into decisions about housing, transport, green spaces and public areas, Zaragoza aims to ensure that urban growth does not create avoidable environmental and health problems.

The approach represents a broader shift in how the city views noise. Rather than treating it as an inevitable consequence of urban life, Zaragoza is making acoustic health a consideration alongside mobility, housing, public health and environmental quality.

The city’s experience highlights how improvements in urban living do not always depend on highly visible infrastructure projects. Careful planning can also help create residential areas where people sleep better, conversations are easier and public spaces are more peaceful.

Through its participation in the Green City Accord and the European Green Capital and Green Leaf Awards, Zaragoza is demonstrating how long-term planning can support efforts to build quieter, healthier and more sustainable cities.
