What You'll Learn
Reduce vehicle use and encourage walking or cycling to school
Reducing vehicle use and encouraging walking or cycling to school is a great way to improve the health and well-being of students and the environment. Here are some ways to achieve this:
Safe Infrastructure and Planning
Implementing infrastructure improvements, such as designated walking and cycling lanes, safe intersections, and well-maintained pathways, is crucial to encouraging active travel. This includes creating safe routes to school that are free from hazardous conditions, ensuring children's safety as they walk or cycle. Additionally, integrating cycling and walking into urban and transport planning can help reduce car dependency and make schools more accessible for those on foot or bike.
Education and Encouragement Programs
Education is key to encouraging behaviour change. Schools can educate students about the benefits of walking and cycling, including improved physical and mental health, environmental advantages, and road safety skills. They can also provide incentives and run programs to encourage active travel, such as the Safe Routes to School program, which has been successful in increasing walking and cycling to school while reducing traffic congestion.
Collaboration with Local Authorities
Schools and communities should work with local authorities to relocate traffic intersections and bus stops away from school premises. They can also advocate for the development of national cycling and walking plans, reallocating space for these active travel modes and improving safety.
Reducing Vehicle Use During Drop-Off and Pick-Up
Schools can discourage vehicle use during drop-off and pick-up times by relocating drop-off/pick-up points away from school entrances and encouraging staggered drop-off times, carpool clubs, and respecting no-stop areas. This not only reduces students' exposure to harmful vehicular pollutants but also helps reduce congestion and improves the overall air quality around the school.
By implementing these strategies, schools can play a vital role in reducing vehicle use and promoting walking or cycling as healthy, environmentally friendly alternatives.

Improve indoor air quality with air purifiers and filtration systems
Improving indoor air quality is essential to providing a healthy learning environment for students. Schools can take several measures to ensure that the air inside classrooms is clean and safe to breathe.
One effective way to improve indoor air quality is by investing in air purifiers and filtration systems. Air purifiers with High-Efficiency Particulate Air (HEPA) filters can effectively remove pollutants such as dust, pollen, and other airborne particles. Schools should ensure that these air purifiers are regularly cleaned and maintained for optimal performance. Additionally, proper ventilation systems should be installed to mitigate indoor air pollution and minimise the infiltration of outdoor pollutants. Schools should also consider implementing an Indoor Air Quality (IAQ) management program, such as the one suggested by the US EPA's IAQ Tools for Schools, to develop and sustain an effective and comprehensive program using simple, low-cost actions.
To further enhance the effectiveness of air purifiers and filtration systems, schools can encourage the adoption of pollution prevention practices. For instance, students can be taught to turn off lights, monitors, and electronic devices when not in use, reducing energy consumption and associated pollution. Schools can also promote initiatives such as "half-lighting," where only half the lights in a classroom are turned on if there is sufficient natural lighting. Additionally, schools can encourage students to walk or cycle to school, reducing vehicle emissions and improving the overall air quality in the vicinity.
Another strategy to improve indoor air quality is to address outdoor pollution sources near the school premises. Schools can work with local authorities to relocate traffic intersections and bus stops away from the school, reducing the concentration of pollutants that students are exposed to during drop-off and pick-up times. Schools can also suggest alternative, cleaner walking and cycling routes to parents, encouraging them to avoid main roads with high vehicular emissions. Implementing no-idling policies for school buses and private vehicles can also significantly reduce pollution levels near the school.
By combining the use of air purifiers and filtration systems with pollution prevention practices and addressing outdoor pollution sources, schools can effectively improve indoor air quality and create a healthier environment for students and staff.

Minimise time spent near traffic intersections and bus stops
Minimising the time spent near traffic intersections and bus stops is a crucial step in reducing exposure to harmful vehicular pollutants, especially for children who are more vulnerable to air pollution due to their developing organs and higher breathing rates. Here are some strategies to achieve this:
Traffic Intersections
- Local authorities should be encouraged to move traffic intersections away from school premises where possible.
- Schools can promote alternative, low-traffic routes to students and parents, helping them avoid congested intersections.
- Implementing priority merge rules, where vehicles are required to yield to buses re-entering the traffic stream, can reduce bus delays and decrease traffic congestion at intersections.
- Grade separations at congested intersections can help mitigate congestion and improve traffic flow.
Bus Stops
- Schools should encourage students and parents to walk or cycle to and from school, reducing their exposure to bus stop pollutants and improving their health.
- For schools with bus transportation, the use of bus bays located at the far side of intersections can minimise delays and reduce time spent near intersections.
- Bus operators should avoid bus bays and aim to stop in curb lanes where possible, as this prevents delays when re-entering traffic.
- Schools can suggest the use of pram covers for young children at bus stops, acting as a physical barrier between them and vehicle emissions. However, these should not be used for extended periods to avoid carbon dioxide accumulation.
By implementing these strategies, schools can effectively minimise the time spent by students and parents near traffic intersections and bus stops, thereby reducing their exposure to harmful vehicular pollutants.

Implement no-idling policies for vehicles outside schools
Children are more vulnerable to air pollution than adults because their organs and natural defenses are still developing, and they breathe more frequently, increasing their intake of pollutants. Schools can play a vital role in reducing this exposure by implementing no-idling policies for vehicles outside their premises.
A no-idling policy is a simple and effective measure to protect students from harmful vehicle emissions. Idling vehicles waste fuel and increase wear and tear on engines, and, most importantly, emit pollutants that can negatively impact children's health. Schools can take several steps to implement such a policy successfully. Firstly, it is crucial to spread awareness about the policy among parents, bus drivers, and truck drivers. This can be done through various mediums such as signs, flyers, mailers, newsletters, and online articles. Educating the community about the harmful effects of idling and the benefits of turning off engines while waiting is essential for gaining support for the policy.
To further encourage compliance, schools can provide alternative options for drop-off and pick-up. This may include relocating drop-off and pick-up points away from the school entrance, staggering drop-off times, or encouraging carpool clubs. Implementing no-stop zones, such as double yellow lines, around the school can also help reduce idling. Additionally, schools can promote mitigation measures to parents, such as choosing low-traffic routes to and from school and minimizing time spent at pollution hotspots like traffic intersections and bus stops.
To measure the success of the no-idling policy, schools can count the number of vehicles idling during student drop-off and pick-up before and after implementing the policy. A significant reduction in idling vehicles is an indicator of the policy's effectiveness. Schools can also notify parents and carers about the risks of commuting via main roads and suggest alternative, cleaner routes to reduce exposure to vehicular emissions. By implementing a no-idling policy and taking these accompanying measures, schools can improve the air quality at the school entrance and positively impact the health and well-being of their students.

Educate students on pollution and how to prevent it
Education is a powerful tool to prevent pollution in schools. Teachers can raise awareness about pollution and its consequences, empowering students to become agents of change. Here are some ways to educate students on pollution and how to prevent it:
Teach About Different Types of Pollution
Instructors can begin by explaining the various types of pollution, including air, water, and land pollution. They can provide real-world examples, such as the impact of pollution on rivers, lakes, and drinking water, as well as its contribution to global warming. For instance, students can learn that approximately 50% of the world's population faces issues with polluted drinking water, and this leads to around 5 to 10 million deaths annually.
Hands-on Activities and Experiments
Students can actively engage with the topic through hands-on activities and experiments. They can participate in clean-up drives, picking up discarded items and learning about proper disposal and recycling techniques. Additionally, students can be encouraged to walk or cycle instead of taking a car, reducing vehicle emissions.
Energy Conservation and Efficient Appliances
Educators can teach students about energy conservation and the importance of using efficient appliances. Students can be encouraged to turn off lights and electronic devices when not in use, both at school and at home. They can also learn about the benefits of using eco-friendly and energy-efficient products, such as switching to electric or hand-powered lawn equipment.
Repair and Reuse
Instructors can promote the concepts of repair and reuse to students. For example, students can be tasked with finding broken items at home, such as torn clothing or broken decorations, and learning how to repair them. They can then present their repair processes to the class, creating a digital repair guidebook that can be shared with others. This encourages a culture of fixing items instead of immediately discarding them, reducing waste.
Group Discussions and Brainstorming
Teachers can facilitate group discussions and brainstorming sessions where students work collaboratively to identify environmental issues and propose solutions. By dividing the class into groups representing different levels of government, students can debate and reach a consensus on strategies to prevent pollution. These discussions can lead to the creation of detailed reports and presentations, fostering critical thinking and a sense of ownership in addressing pollution.
