Exploring Innovative Strategies for Improving Air Quality in Urban Schools Across the UK

The Urgent Need for Clean Air in Schools

Air quality is a critical issue that affects the health and well-being of everyone, particularly children and young people. In urban areas, schools are often located in environments where air pollution is rampant, posing significant risks to the health of students and staff. The UK, with its densely populated cities, is no exception. This article delves into the innovative strategies being implemented to improve air quality in urban schools, highlighting the importance of clean air, the impact of pollution, and the best practices that are making a difference.

Understanding the Impact of Air Pollution on Health

Air pollution is a major public health concern, especially in urban settings. Schools, where children spend a significant amount of their day, are often situated in areas with high levels of pollutants such as particulate matter (PM2.5), nitrogen dioxide (NO2), and other harmful gases. These pollutants can lead to a range of health issues, including respiratory problems, asthma, and even adverse birth outcomes.

A study by the Children, Cities and Climate Action Lab (CCC) revealed that achieving ‘net zero’ in 16 global cities could prevent 20,000 childhood asthma cases and 65,000 adverse birth outcomes annually[1]. This underscores the urgent need for effective air quality management in schools.

Innovative Technologies for Air Quality Monitoring

One of the first steps in improving air quality is accurate monitoring. Local governments and schools are increasingly turning to innovative technologies to track and manage air pollution.

Airly, a company specializing in air quality monitoring, offers real-time monitoring, AI forecasting, and affordable wearable air sensors. These tools enable local authorities to gather detailed data on air quality, which is crucial for developing targeted interventions[4].

For example, a study in Southwark, London, used air purifiers in schools and care homes to reduce indoor air pollution. The study found that air purifiers could reduce PM2.5 levels by 18% in classrooms and 38% in care homes, highlighting the effectiveness of such technologies in real-world settings[2].

Effective Interventions for Reducing Air Pollution

Several interventions have been identified as effective in reducing air pollution around schools:

Low-Emission Zones (LEZs)

LEZs are areas where only vehicles that meet certain emissions standards are allowed to enter. A study in England found that LEZs were highly effective in reducing NO2 concentrations at schools, especially when implemented within a 500-meter radius[5].

Improved Travel Routes

Changing travel routes to avoid heavily polluted areas can significantly reduce exposure to air pollutants. This intervention was found to be particularly effective for reducing NO2 concentrations along travel routes[5].

Active Travel

Encouraging active travel, such as walking or cycling, can reduce emissions from vehicles and improve air quality. This approach is not only beneficial for air quality but also promotes physical health and well-being[5].

Air Purifiers

As mentioned earlier, air purifiers can significantly improve indoor air quality. Here are some key points from the Southwark study:

• For Managers: Simple advice on selecting, deploying, and maintaining air purifiers, including considerations for energy costs and outdoor air quality.
• For Users: Air purifiers can be left on continuously to provide benefits. Doors and windows should be kept closed when rooms are not in use to maximize air purification.
• For Government: There is a need for standards and regulations for indoor air pollution in schools and care homes.
• For Local Government and Third Sector: Guidance is necessary to help schools and care homes understand the benefits and effective use of air purification technologies[2].

Community Engagement and Youth Involvement

Community engagement and youth involvement are crucial in addressing environmental challenges. The Children, Cities and Climate Action Lab (CCC) has been at the forefront of this effort.

In a series of workshops held in Lagos and Nairobi, the CCC brought together 47 young people to develop advocacy strategies for improving air quality and creating healthier, safer cities. These workshops used creative methods such as vision boards, visual mapping, and photo sharing to engage participants in meaningful discussions about urban climate action. The participants identified key strategy areas including transportation, waste management, advocacy communication, and transitioning to green energy[1].

Role of the Creative Sector in Environmental Protection

The creative sector can play a significant role in protecting environmental sites and improving air quality. A project by Policy Lab in collaboration with Natural England explored how creative practitioners in higher education could contribute to environmental policy outcomes.

The project found that there is a fertile space for partnership between creative practitioners and policymaking teams. Ideas such as student placements, course integrations, summer schools, and on-site workshops were suggested to catalyze transformative partnership working. This approach not only engages young people in environmental issues but also brings innovative solutions to the table[3].

Best Practices for Local Authorities

Local authorities have a critical role in improving air quality in schools. Here are some best practices that can be adopted:

• Implement LEZs: Establish low-emission zones around schools to reduce vehicle emissions.
• Promote Active Travel: Encourage walking, cycling, or carpooling to reduce the number of vehicles on the road.
• Use Air Purifiers: Install and maintain air purifiers in schools to improve indoor air quality.
• Conduct Regular Monitoring: Use advanced technologies to monitor air quality in real-time and adjust strategies accordingly.
• Engage the Community: Involve local communities, including young people, in developing and implementing air quality improvement plans.

Practical Insights and Actionable Advice

For those looking to improve air quality in schools, here are some practical insights and actionable advice:

For Schools

• Install Air Purifiers: Consider installing air purifiers in classrooms and common areas to reduce indoor air pollution.
• Promote Green Practices: Encourage green practices such as recycling, reducing waste, and using energy-efficient appliances.
• Educate Students: Incorporate environmental education into the curriculum to raise awareness about air quality and its impact on health.

For Local Authorities

• Develop Action Plans: Create comprehensive action plans that include interventions such as LEZs, improved travel routes, and active travel initiatives.
• Provide Guidance: Offer guidance to schools on the effective use of air purification technologies and other interventions.
• Collaborate with Communities: Engage with local communities and involve them in the development and implementation of air quality improvement strategies.

Improving air quality in urban schools is a multifaceted challenge that requires innovative strategies, community engagement, and the involvement of young people. By leveraging advanced technologies, implementing effective interventions, and fostering partnerships between local authorities, schools, and the creative sector, we can create cleaner, healthier environments for children to learn and grow.

As Dr. Robert Hughes of LSHTM noted, “Through coming together across disciplines and generations, we really can make a stronger case for making our cities healthier and more sustainable.”[1] This collaborative approach is essential for addressing the complex issues surrounding air quality and ensuring a better future for our children.
