Solving Slovakia's Air Pollution Crisis

Slovakia has an air pollution problem, with the country exceeding EU limits for harmful substances. The main sources of air pollution in Slovakia are power generation, the manufacturing industry, food processing, vehicle emissions, and domestic heating with solid fuels. To address this issue, Slovakia has implemented a Strategy for the reduction of PM10 since 2013 and adopted programs to improve air quality in areas with high levels of pollution. Additionally, the Global Environment Facility has funded a project to reduce greenhouse gas emissions and improve local air pollution by replacing coal-fired boilers with those using wood pellets. Other measures to improve air quality include supporting public transportation, diverting transit from road to rail, and developing bicycle infrastructure.

Reduce vehicle emissions

Vehicle emissions are a major contributor to air pollution in Slovakia, particularly in large cities. To reduce vehicle emissions, the following measures can be implemented:

Support for Public Transport

The Slovakian government can encourage the use of public transport by investing in new, modern buses and improving the overall reliability and comfort of public transport services. This will help to reduce the number of private vehicles on the road, thereby decreasing vehicle emissions. For instance, the city of Košice in East Slovakia has seen success with this strategy, having purchased a fleet of modern, low-emission buses that comply with strict EU emissions standards. This has not only improved passenger comfort and reliability but has also helped to reduce transport costs and emissions.

Modernising the Vehicle Fleet

Upgrading the country's vehicle fleet to more environmentally friendly models can significantly reduce emissions. This includes encouraging the use of electric vehicles (EVs) and discouraging the use of diesel vehicles, particularly in urban areas. The EURO 6 diesel vehicle, for example, has been shown to effectively reduce dust particle emissions. Additionally, removing older, less efficient vehicles from the road can also help improve air quality.

Transit Diversion

Redirecting transit traffic, such as goods transportation, from road freight to rail can help reduce the number of heavy-duty diesel trucks in city centres. This will not only improve air quality but also reduce congestion and traffic problems in urban areas.

Bicycle Infrastructure Development

Building dedicated bicycle infrastructure in cities can promote cycling as a mode of transportation. This will not only reduce vehicle emissions but also contribute to the overall health and well-being of the population.

Public Awareness and Education

Improving public awareness and education about the impact of vehicle emissions on air quality can motivate individuals to make more environmentally friendly choices. This includes encouraging the use of electric or hybrid vehicles, carpooling, or opting for environmentally friendly modes of transportation such as bicycles or public transport.

Improve public transport

Public transport is a significant contributor to air pollution in Slovakia, particularly in large cities like Bratislava. To reduce air pollution, measures should be taken to encourage the use of public transport over private vehicles.

Firstly, investing in cleaner vehicles for public transport fleets can help improve air quality. For instance, the city of Bratislava could encourage the use of electric or hybrid buses, which would reduce emissions from transport, a major source of air pollution.

Secondly, integrating different modes of public transport can make it more attractive for people to use. Bratislava already has an integrated transport system, IDS BK, which allows passengers to use the same ticket for trams, buses, and trains operated by different companies. This kind of integration could be expanded nationwide, making it easier for people to travel between cities and reducing the need for private cars.

Thirdly, improving the frequency and reliability of public transport services can make it a more appealing option for commuters. This can be achieved by investing in more buses, trains, and other forms of public transport, as well as improving the infrastructure, such as designated bus lanes, to reduce travel times.

Finally, making public transport more affordable can also encourage its use. While Slovakia already has some initiatives for free or discounted public transport, such as for students, expanding these initiatives or reducing ticket prices can make a significant difference. For example, offering discounted tickets for multiple journeys or monthly passes can incentivize commuters to switch from private cars to public transport.

By implementing these measures, Slovakia can improve its public transport system, reduce air pollution, and create a more sustainable future for its citizens.

Reduce fossil fuel usage

Fossil fuels are a major contributor to air pollution in Slovakia, with combustion of coal and biomass (especially undried wood) being a significant source of harmful emissions. To reduce air pollution, it is imperative that Slovakia reduces its reliance on fossil fuels and transitions to cleaner, renewable sources of energy. Here are some ways in which Slovakia can reduce its fossil fuel usage:

Energy Sources and Appliances

• Transition to renewable energy sources such as solar energy.
• Encourage the use of electric heating systems, such as heat pumps, instead of fossil fuel-based heating.
• Promote the use of energy-efficient appliances with the ENERGY STAR label, which meet high-efficiency standards and reduce energy consumption.
• Implement policies to support the development and utilisation of clean and renewable energy technologies, such as wind and solar power.

Transportation

• Develop and improve public transportation systems to reduce the number of cars on the road. This includes investing in electric buses and other clean vehicles.
• Encourage carpooling, bicycling, and walking as alternative modes of transportation to reduce the number of vehicles on the road.
• Divert transit by transferring goods from road freight to rail, thereby reducing the number of heavy-duty diesel trucks in city centres.
• Construct dedicated cycling infrastructure to make bicycling a safer and more attractive option for commuters.

Industrial and Agricultural Practices

• Support the adoption of environmentally friendly industrial practices, such as the use of pushable lawn mowers and the reduction of space that requires mowing.
• Encourage farmers to reduce methane emissions by optimising feed digestibility and improving grazing and pasture management practices.
• Implement policies and regulations to reduce emissions from the chemical and mining industries, which rely heavily on fossil fuels and solvents.

Individual Actions

• Encourage individuals to reduce their meat consumption and increase their intake of vegetables and fruits, as agriculture is a significant source of methane emissions.
• Promote the use of reusable containers, such as fabric bags for groceries, to reduce the demand for plastic production, which relies on fossil fuels.
• Educate the public about the benefits of recycling and reusing products to reduce the demand for fossil fuel-intensive production processes.
• Encourage the use of natural alternatives, such as beeswax for waxing floors, instead of commercial waxes made from petroleum derivatives.

Improve public awareness

Improving public awareness is key to tackling Slovakia's air pollution problem. Here are some measures that can be taken:

• Education and awareness campaigns: The public needs to understand the impact of air pollution on their health and the environment. Campaigns can highlight the risks of air pollution, such as respiratory diseases, heart attacks, lung cancer, and stroke. Moreover, people should be made aware of the sources of air pollution, such as vehicle emissions, power generation, and the burning of fossil fuels and biomass.
• Emphasise the importance of individual actions: People need to realise that their choices have an impact on air quality. For example, opting for environmentally friendly transport options like electric cars, bicycles, or public transport can significantly reduce air pollution. Similarly, encouraging the use of cleaner and more efficient heating sources, such as natural gas or renewable alternatives, can help improve air quality, especially in rural areas.
• Provide real-time air quality data: Making air quality information accessible to the public can help individuals make informed decisions. For example, on days when air pollution levels are high, people can be advised to minimise outdoor activities and take precautions such as wearing masks. This can help reduce the health risks associated with air pollution.
• Promote behavioural changes: In addition to raising awareness, it is important to encourage behavioural changes that can improve air quality. For example, people can be encouraged to reduce meat consumption, as agriculture is a significant source of air pollution. Promoting waste reduction and responsible waste management practices can also help address the issue.
• Collaboration with media and influencers: Partnering with local media outlets and influencers can help spread awareness more effectively. Using various communication channels, such as social media, television, and radio, can ensure that the message reaches a wider audience.

By implementing these strategies, Slovakia can empower its citizens to take an active role in improving air quality and protecting their health and the environment.

Reduce agricultural emissions

Agriculture is a significant contributor to air pollution and greenhouse gas emissions in Slovakia. To reduce agricultural emissions, several measures can be implemented:

• Reducing Livestock Numbers: Since 1990, Slovakia has witnessed a decline in livestock numbers, particularly cattle, pigs, and poultry, which has contributed to lower ammonia and methane emissions. This trend can be further encouraged through various means, such as incentives for farmers to adopt alternative farming practices or promote plant-based agriculture.
• Improving Livestock Management: Optimising feed digestibility and enhancing grazing and pasture management can help reduce methane emissions from livestock. Additionally, proper manure management techniques, such as storage methods that minimise methane emissions, can further reduce agricultural emissions.
• Reducing Nitrogen Fertilizer Use: Agricultural soils are a significant source of nitrous oxide emissions. By reducing the consumption of inorganic nitrogen fertilizers, Slovakia can decrease these emissions. Alternative farming practices that promote sustainable soil management and organic farming methods can be encouraged.
• Promoting Eco-Friendly Energy Sources: Transitioning from fossil fuels to renewable energy sources for agricultural activities can help reduce carbon dioxide and methane emissions. This includes adopting eco-friendly alternatives for heating and powering agricultural equipment.
• Educating Farmers: Providing educational resources and training to farmers on sustainable practices can empower them to make environmentally conscious decisions. This includes raising awareness about the impact of agricultural activities on air pollution and offering guidance on mitigating measures.
• Supporting Policy Changes: Implementing policies that incentivise sustainable farming practices and disincentivise environmentally harmful ones can drive systemic change. This includes subsidies for farmers who adopt eco-friendly practices and stricter regulations on emissions from agricultural activities.

By implementing these strategies, Slovakia can effectively reduce agricultural emissions and contribute to improving air quality and mitigating climate change.
