Government Strategies To Reduce Smog And Air Pollution

Since the 1970s, governments have been implementing policies to reduce smog and air pollution. The Clean Air Act, passed in 1970, was the first law to authorize the federal government and states to create regulations to limit emissions from both stationary and mobile sources of air pollution. Since then, the Environmental Protection Agency (EPA) has set and implemented emissions standards to control pollution from various sources, including cars, trucks, power plants, and industrial facilities. These standards have led to significant improvements in air quality and public health. In addition to the EPA's efforts, local and state governments play a crucial role in reducing air pollution by developing enforceable state implementation plans, providing incentives for sustainable practices, and utilizing air quality data to guide planning decisions.

Governments can implement the Clean Air Act to reduce common air pollutants

The Clean Air Act (CAA) is a comprehensive federal law that gives the US Environmental Protection Agency (EPA) the authority to regulate air pollutants and polluting industries. The Clean Air Act has helped reduce common air pollutants, and its benefits can be seen and felt. Here are some ways in which governments can implement the Clean Air Act to reduce common air pollutants:

Regulate Stationary and Mobile Sources of Air Pollution

The Clean Air Act regulates air emissions from both stationary and mobile sources. This includes power plants, industrial facilities, cars, trucks, and off-road engines. The EPA sets National Ambient Air Quality Standards (NAAQS) to protect public health and welfare and directs states to develop implementation plans to achieve these standards.

Establish Health-Based Standards and Reduce Hazardous Air Pollutants

The Clean Air Act requires the EPA to set national health-based standards for air pollution and to review, update, and enforce these standards regularly. Section 112 of the Clean Air Act specifically addresses hazardous air pollutants, requiring the EPA to establish emission standards, known as Maximum Achievable Control Technology (MACT) standards, for major sources of hazardous air pollutants.

Implement Pollution Control Technologies

The EPA can require polluting industries to install appropriate pollution control technologies, such as emission monitoring systems, or change their production processes to reduce emissions. This has been effective in reducing emissions of smog, soot, greenhouse gases, and particulate matter.

Partner with State, Local, and Tribal Governments

The Clean Air Act calls for collaboration between federal, state, local, and tribal governments to reduce air pollution. States play a crucial role in developing enforceable implementation plans to meet national air quality standards. Local governments can also use air pollution data to guide transportation planning and reduce residents' exposure to air pollution.

Encourage Energy Efficiency and Clean Technologies

The Clean Air Act has prompted the deployment of clean technologies and innovations that reduce emissions and control costs. For example, the EPA's SmartWay program has empowered companies to move goods in a cleaner and more energy-efficient way, reducing carbon dioxide and nitrogen oxide emissions.

By effectively implementing the Clean Air Act, governments can make significant progress in reducing common air pollutants, improving public health, and protecting the environment.

The EPA's SmartWay program helps companies move goods efficiently and cleanly

The US government has implemented various initiatives to reduce smog and air pollution, including the Clean Air Act and the Diesel Emissions Reduction Act (DERA). The Environmental Protection Agency (EPA) has also played a crucial role in this effort, with its SmartWay program being a notable example.

The EPA's SmartWay program was launched in 2004 as a voluntary public-private initiative. It aims to help companies move goods efficiently and cleanly by providing a comprehensive system for benchmarking and reporting freight emissions across supply chains. The program has three core components: freight shippers, carriers, logistics companies, and other stakeholders who partner with the EPA to measure, benchmark, and improve logistics operations, reducing their environmental footprint.

SmartWay helps companies identify and select more efficient freight carriers, service providers, transport modes, equipment, and operational strategies. This approach improves supply chain sustainability and lowers costs associated with goods movement. Additionally, it strengthens national energy security and mitigates environmental risks for companies.

Since its inception, SmartWay has achieved significant success. By 2022, nearly 4,000 companies and organizations were participating in the program. SmartWay has helped its partners save millions of barrels of oil, equivalent to eliminating the annual electricity use in millions of homes. The program has also prevented the release of millions of tons of harmful emissions, including carbon dioxide, nitrogen oxides, and particulate matter.

The SmartWay program has been so successful that it has received recognition through the Excellence Award. This award is presented to the top 2% of leading shippers and truck carriers from its extensive list of partners. These awardees are recognized for optimizing the environmental performance and efficiency of their freight operations while demonstrating leadership in freight sustainability.

The Diesel Emissions Reduction Act provides funding for owners to replace diesel equipment

The US government has been taking steps to reduce air pollution and improve air quality since the 1970s. The Clean Air Act, implemented by the Environmental Protection Agency (EPA), is one of the key initiatives in this regard. The Act calls for state, local, federal, and tribal governments to work together to reduce pollution.

One of the programs introduced under the Clean Air Act is the Diesel Emissions Reduction Act (DERA), which provides funding for owners to replace their diesel equipment with cleaner alternatives. DERA is a critical component of the government's strategy to reduce smog and air pollution. Diesel engines, vehicles, and equipment are significant contributors to air pollution, particularly in the form of nitrogen oxides (NOx) and particulate matter (PM2.5). By providing funding to replace or retrofit these diesel systems, DERA helps to accelerate the transition to cleaner technologies and reduce emissions.

DERA grants are available for eligible activities, including the retrofit or replacement of existing diesel engines, vehicles, and equipment with EPA-approved configurations. This includes non-road engines, equipment, or vehicles used in construction, cargo handling, agriculture, mining, or energy production. The EPA has developed tools, such as the TRU Emissions spreadsheet calculator, to help estimate potential emission reductions and fuel savings for projects involving Transport Refrigeration Units (TRUs).

The EPA allocates DERA funds to eligible US states and territories, with a portion of the funding provided as base funding and the remaining allocated as incentives for states that match the base funding. In 2024, the EPA announced the availability of approximately $115 million in DERA funding for 2022 and 2023, with applications accepted until December 1, 2023. Additionally, the EPA has committed $125 million towards upgrading older diesel engines to cleaner and zero-emission solutions by October 17, 2024.

Through initiatives like DERA, the US government is actively working to reduce smog and air pollution by providing funding for the replacement of diesel equipment. This not only helps improve air quality but also offers substantial health benefits and contributes to the fight against climate change.

Local governments can use air pollution data to guide transportation planning

Furthermore, local governments can employ this data to identify areas with high levels of pollution and prioritize them for improvement. This may include implementing low-emission zones (LEZs), where only vehicles that meet strict emission standards are permitted, thereby reducing air pollution in densely populated areas. Additionally, governments can use the data to develop and enforce state implementation plans that comply with national air quality standards, as outlined in the Clean Air Act.

Air pollution data also assists in making informed decisions about infrastructure development. Local authorities can utilize the information to strategically build schools, hospitals, or housing developments farther from major sources of pollution, such as freeways, reducing residents' exposure to harmful emissions. Moreover, data-driven insights enable governments to establish partnerships with companies to improve freight management and promote sustainable practices, such as through the EPA's SmartWay program, which encourages energy efficiency in the transportation of goods.

Public awareness and engagement are also crucial. Local governments can launch educational campaigns to inform citizens about the sources and effects of transport-related pollution, encouraging the adoption of sustainable transport options and supporting policies that promote environmental sustainability. By combining data-driven decision-making with community engagement, local governments can effectively guide transportation planning to reduce air pollution and protect public health.

Governments can provide incentives for beneficial behaviours and educate residents on best practices

Governments can play a crucial role in reducing smog and air pollution by providing incentives for beneficial behaviours and educating residents on best practices. This can be achieved through various policies, programs, and initiatives.

One example is the Clean Air Act, which has been successful in the United States since its implementation in 1970. The Act authorises the federal government and states to regulate emissions from stationary and mobile sources, such as power plants, industrial facilities, vehicles, and trucks. The Environmental Protection Agency (EPA) plays a key role in implementing and enforcing these regulations, working in partnership with state, local, and tribal governments.

To incentivise beneficial behaviours, governments can offer grants, subsidies, or tax breaks to individuals and businesses that adopt more sustainable practices. For instance, the Diesel Emissions Reduction Act provides funding for owners to replace their diesel equipment with cleaner alternatives, resulting in significant NOx and particulate matter emission reductions. Similarly, the SmartWay program encourages companies to move goods in a more energy-efficient manner, leading to substantial fuel cost savings and emission reductions.

Education is another powerful tool in reducing smog and air pollution. Governments can launch awareness campaigns, develop educational programs, and utilise platforms like AirNow to provide real-time information on air quality and criteria pollutants. This empowers residents to make informed decisions and take individual action to reduce their contribution to air pollution.

In addition to incentives and education, governments can promote best practices by partnering with local businesses, city offices, and school districts. For example, the Small Business Environmental Assistance Program in Minnesota helps businesses reduce waste, emissions, and regulatory obligations. Governments can also pass local ordinances that encourage sustainable behaviours, such as carpooling, biking, or using public transportation, and promote the use of electric vehicles to reduce vehicle exhaust emissions.

By combining incentives, education, and the promotion of best practices, governments can effectively engage residents in the collective effort to reduce smog and air pollution, leading to improved public health and environmental outcomes.
