Reducing the Number of Cars on the Road in Tehran

Tehran, the capital of Iran, is one of the most polluted cities in the world, with smog often blanketing parts of the city. A staggering 80% of the city's pollution comes from cars, with the remaining 20% attributed to industrial sources.

Improving Public Transport

The Iranian government has been working to address this issue, and in 2011, improvements to the public transport system, along with rising fuel prices, were expected to help alleviate pollution and traffic congestion. Enhancing public transportation is a crucial step in reducing the number of private cars on the road. By providing efficient, reliable, and affordable alternatives, such as buses, subways, or trams, more people may be encouraged to leave their cars at home.

Encouraging Active Transportation

Another strategy is to promote active transportation, such as walking and cycling, by developing pedestrian-friendly infrastructure. This can include creating dedicated bike lanes, improving sidewalks, and making intersections safer for pedestrians and cyclists. Implementing policies that discourage car use, such as congestion charges or parking restrictions, can also incentivise people to opt for walking or cycling for shorter distances.

Enhancing Traffic Management

Traffic management strategies can also play a role in reducing the number of cars on Tehran's roads. This includes measures such as optimising traffic signal timing, introducing one-way streets, or implementing road diet strategies to reduce the number of lanes allocated for vehicular traffic, making room for dedicated bus lanes or bike lanes.

Promoting Carpooling and Shared Mobility

Encouraging carpooling is another effective way to decrease the number of cars on the road. This can be achieved by providing incentives for carpooling, such as designated high-occupancy vehicle (HOV) lanes or priority parking for carpoolers. Additionally, promoting shared mobility services, such as ride-sharing apps or car-sharing programs, can help reduce the overall number of vehicles on the road.

Restricting Car Ownership and Use

In the long term, implementing policies that restrict car ownership and use can have a significant impact. This could include measures such as congestion charges, low-emission zones, or other financial disincentives for private car ownership. By making cities more people-friendly than car-friendly, the number of vehicles on the road can be effectively reduced.

Improve public transport

Tehran, the capital of Iran, is one of the most polluted cities in the world. The city's pollution is caused by a combination of industrial activity, vehicle emissions, and geographical factors.

Improving public transportation is a crucial strategy to reduce pollution in Tehran. Here are some measures that can be implemented to achieve this:

Expand and Modernize the Public Transport Fleet:

Tehran suffers from a severe lack of public transportation options, which contributes to the high number of private vehicles on the roads. The government should invest in expanding the fleet of buses, trams, or other mass transit options. These should be modern, environmentally friendly vehicles that meet high emission standards. This will provide a more efficient and attractive alternative to private cars, reducing congestion and pollution.

Improve Infrastructure for Sustainable Transport:

The development of dedicated bus lanes, light rail systems, or other rapid transit networks can significantly enhance the efficiency and appeal of public transportation. This includes constructing bus rapid transit (BRT) corridors, which provide buses with a separate lane to reduce travel time and improve reliability. Additionally, investing in pedestrian and bicycle infrastructure, such as dedicated lanes, pathways, and safe intersections, can encourage active transportation and reduce the reliance on motorised transport.

Enhance Connectivity and Accessibility:

Integrating different modes of public transportation, such as buses, trains, and subways, can improve connectivity across the city. This involves ensuring seamless transfers between different transport modes and providing real-time information to passengers through mobile apps or displays at stations. Furthermore, introducing measures such as discounted fares for off-peak travel or monthly passes can make public transportation more affordable and attractive to commuters.

Promote Green Energy for Public Transport:

Encouraging the use of alternative fuels, such as compressed natural gas (CNG) or electric power, for the public transport fleet can significantly reduce emissions. The government can provide subsidies or incentives for transport operators to adopt these cleaner technologies, ensuring that the financial burden of transitioning to greener energy is not passed on to commuters.

Optimise Routing and Scheduling:

Utilising data analytics and intelligent transport systems can help optimise the routing and scheduling of public transport vehicles. This ensures that buses or trains are deployed efficiently, reducing unnecessary emissions and providing better service to commuters.

By implementing these measures, Tehran can significantly improve its public transportation system, making it a more attractive and sustainable option for commuters, ultimately contributing to reduced pollution levels in the city.

Move industries out of the city

Tehran, the capital of Iran, is one of the world's most polluted cities. The city's pollution is caused by a combination of industrial activity, vehicle emissions, and geographical factors. A significant contributor to the city's pollution is the large number of factories and industrial areas bordering Tehran.

To reduce pollution, one possible strategy is to move these industries out of the city. This approach has been successfully implemented in other cities around the world and could have several benefits for Tehran. Firstly, it would reduce the concentration of pollutants emitted by factories and heavy machinery in the city centre. Secondly, it would help alleviate the issue of traffic congestion caused by industrial vehicles.

When considering the relocation of industries, several factors need to be taken into account. Firstly, the new location should be carefully chosen to ensure that the industries are moved to an area with adequate infrastructure and resources to support their operations. This includes access to transportation networks, utilities, and skilled labour. Additionally, the environmental impact of the relocation should be assessed to ensure that the new site can accommodate the industries without causing significant harm to the surrounding ecosystem.

Furthermore, the government should provide incentives and support to businesses to facilitate their move. This could include financial assistance, tax breaks, or the development of industrial parks or special economic zones in the new location. By providing these incentives, the government can encourage businesses to relocate voluntarily, rather than through mandatory measures, which may cause disruptions and increase costs for businesses.

Finally, the relocation of industries should be accompanied by other pollution-reduction strategies to ensure a comprehensive approach. This includes continuing to improve public transportation, encouraging the use of cleaner energy sources, and implementing stricter emission regulations for vehicles. By combining the relocation of industries with other initiatives, Tehran can effectively reduce its pollution levels and improve the health and well-being of its citizens.

Improve fuel quality

Tehran, the capital of Iran, has been rated as one of the world's most polluted cities. The city's pollution is largely due to cars and motorcycles, which account for 80% and 30% of air pollution, respectively. In addition, the Iranian government has allowed its refineries to produce sub-par gasoline due to international sanctions. This has resulted in poor-quality gasoline contributing to the city's air pollution problem.

To improve fuel quality and reduce pollution in Tehran, the following measures can be implemented:

• Reduce Sulphur Content in Fuel: Lowering Sulphur levels in gasoline and diesel to below 10ppm is crucial. This will not only ensure the proper functioning of emission control systems but also improve air quality. Sulphur dioxide (SO2) is a harmful pollutant that contributes to acid rain and negatively impacts human health. Reducing Sulphur content in fuel will help mitigate these adverse effects.
• Enforce the Use of Unleaded Fuel: Regulatory obligations have led to the elimination of lead in fuel in almost all countries. This is an important step toward improving fuel quality and reducing harmful emissions.
• Implement Advanced Emission Control Systems: Both cleaner fuels and advanced emission control systems, such as catalytic converters, are necessary to reduce tailpipe emissions. These systems help clean exhaust gases and minimize the release of harmful pollutants.
• Improve Refinery Standards: Iranian refineries should be encouraged to upgrade their processes and produce higher-quality gasoline that meets international standards. This will help reduce the negative impact of poor-quality fuel on the environment and human health.
• Encourage the Use of Compressed Natural Gas: The Iranian government has already taken steps to encourage taxis and buses to switch from petrol engines to engines that run on compressed natural gas. This initiative should be further promoted and incentivized to reduce pollution from vehicles.
• Educate Citizens on Fuel Quality: Raising awareness among citizens about the importance of fuel quality and its impact on the environment can lead to collective efforts to demand and adopt higher standards.
• Regular Vehicle Maintenance: Educating vehicle owners about the importance of regular maintenance can also help improve fuel efficiency and reduce emissions. Proper maintenance ensures that vehicles burn fuel more efficiently and release fewer pollutants.
