Japan's Air Pollution: Strategies For A Cleaner Future

Japan has been a global leader in advocating for the reduction of short-lived climate pollutants (SLCPs) since 2012, when it became a Climate and Clean Air Coalition (CCAC) Partner. The country has been working to reduce air pollution by focusing on energy efficiency and the lifecycle management of hydrofluorocarbons (HFCs). In this chapter, we will explore the air pollution issues in Japan and the world, including pollution caused by sulfur dioxide (SO2) and suspended particulate matter (SPM). We will also discuss Japanese air pollution policy measures and potential solutions, such as the promotion of electric vehicles to reduce vehicle emissions.

Reducing emissions from vehicles by encouraging the use of green vehicles, such as electric and fuel cell cars

Japan has been a global leader in advocating for short-lived climate pollutants (SLCPs) reductions since becoming a Climate and Clean Air Coalition (CCAC) Partner in 2012. The country has also supported the CCAC Trust Fund, which has helped cities and countries across Asia to develop municipal solid waste plans to reduce SLCPs.

One way to reduce emissions from vehicles is to encourage the use of green vehicles, such as electric and fuel cell cars. These vehicles were not available when Japan was initially coping with air pollution, but they are now a powerful substitute for conventional vehicles. Electric vehicles run on electricity and emit no pollutants when running, and the same is true of fuel cell vehicles, which use hydrogen. If electricity is generated from renewable energy sources, CO2 will not be produced. Promoting the use of electric vehicles can be an effective measure to reduce both air pollution and global warming.

The Japanese government can encourage the use of green vehicles by offering incentives such as tax breaks or subsidies for those who purchase them. They can also invest in the development of infrastructure to support these vehicles, such as charging stations for electric cars. In addition, the government can continue to tighten the allowable maximum desired value for emissions from vehicles, with a particular focus on high-emitting heavy-duty trucks and buses.

By implementing these measures, Japan can reduce emissions from vehicles and improve air quality, contributing to the country's overall efforts to combat climate change and promote clean air.

Implementing stricter regulations and standards on air pollution, such as the Air Pollution Control Law

Implementing stricter regulations and standards on air pollution in Japan can be a powerful lever to improve air quality. The country already has the Air Pollution Control Act, which has been used to continuously tighten the allowable maximum desired value for emissions from vehicles, with a particular focus on high-emitting heavy-duty trucks and buses.

However, more can be done to strengthen these regulations and standards. For example, Japan could set more ambitious targets for reducing emissions from the transport sector, which is a major contributor to air pollution. This could include incentivising the adoption of green vehicles, such as electric and fuel cell cars, which emit no pollutants when running. If the electricity used to power these vehicles is generated from renewable sources, this would also help to reduce CO2 emissions.

Additionally, Japan could introduce regulations to specifically target other air pollutants, such as sulfur dioxide (SO2) and suspended particulate matter (SPM), which are known to have harmful effects on human health. These regulations could include setting emission standards for industrial facilities and power plants, as well as implementing measures to reduce pollution from agricultural activities, such as the use of methane-producing fertilisers.

To support the implementation of these stricter regulations, Japan could also invest in the development of new technologies and infrastructure to monitor and control air pollution. This could include the deployment of air quality sensors and the establishment of a real-time air quality monitoring system, which would help to identify pollution hotspots and inform policy decisions.

By taking these steps, Japan can demonstrate its continued commitment to addressing air pollution and improving the health and well-being of its citizens. These measures are also in line with the country's global leadership role in advocating for reductions in short-lived climate pollutants, particularly through its dedication to the lifecycle management of Hydrofluorocarbons (HFCs).

Reducing cross-border air pollution from the rapidly growing Asian region

Japan has been a Climate and Clean Air Coalition (CCAC) Partner since 2012 and has been advocating for reductions in short-lived climate pollutants (SLCPs), particularly through pursuing energy efficiency. Japan has also supported the CCAC Trust Fund, which has helped cities and countries across Asia to develop municipal solid waste plans to reduce SLCPs.

In the transport sector, the allowable maximum value for emissions from vehicles has been continuously tightened over the years, with a focus on high-emitting heavy-duty trucks and buses. This is based on the Air Pollution Control Act.

To reduce air pollution and global warming, Japan could promote the use of green vehicles, such as electric vehicles and fuel cell vehicles, as a substitute for conventional vehicles. These vehicles emit no pollutants when running and, if electricity is generated from renewable energy sources, no CO2 will be produced.

Reducing emissions of highly potent short-lived climate pollutants like methane, black carbon and HFCs

Japan has been a Climate and Clean Air Coalition (CCAC) Partner since 2012 and has been advocating for reductions in short-lived climate pollutants (SLCPs). One of the ways Japan is reducing emissions is by focusing on highly potent but short-lived climate pollutants like methane, black carbon and hydrofluorocarbons (HFCs).

Japan has been supporting cities and countries across Asia to develop municipal solid waste plans to reduce SLCPs. The country has also tightened the allowable maximum desired value for emissions from vehicles, with a focus on high-emitting heavy-duty trucks and buses. This is based on the Air Pollution Control Act.

Japan is also pursuing energy efficiency as a key strategy for combatting these lethal super pollutants. This includes a dedication to the lifecycle management of HFCs, which demonstrates the country's commitment to the current and future climate, as well as clean air.

Another way to reduce emissions is by promoting the use of green vehicles, such as electric vehicles and fuel cell vehicles. These vehicles emit no pollutants when running and can be powered by renewable energy sources, meaning CO2 will not be produced.

Encouraging the use of renewable energy sources to generate electricity, reducing CO2 production

Encouraging the use of renewable energy sources to generate electricity is a crucial step in reducing CO2 production and improving air quality in Japan. Here are some strategies to achieve this:

Firstly, Japan can promote the adoption of green vehicles, such as electric vehicles (EVs) and fuel cell vehicles. These vehicles emit no pollutants when running, and if their electricity is sourced from renewable energy, they can significantly reduce CO2 emissions. The Japanese government can offer incentives such as subsidies or tax breaks to individuals and businesses to encourage the purchase and use of these vehicles.

Secondly, Japan has already demonstrated its commitment to reducing short-lived climate pollutants (SLCPs) and pursuing energy efficiency. Building on this, the country can further invest in renewable energy infrastructure, such as solar and wind power. By increasing the capacity for renewable energy generation, Japan can reduce its reliance on fossil fuels and decrease CO2 emissions.

Additionally, Japan can continue to tighten vehicle emission standards, especially for high-emitting heavy-duty trucks and buses, as outlined in the Air Pollution Control Act. This can be coupled with initiatives to promote public transportation and reduce the overall number of vehicles on the road, thereby lowering emissions from the transport sector.

Furthermore, Japan can encourage the development and utilisation of energy storage technologies, such as advanced batteries and hydrogen fuel cells. These technologies can help balance the intermittent nature of renewable energy sources and improve the stability of the electricity grid. By investing in research and development and providing incentives for their deployment, Japan can accelerate the transition to a cleaner energy system.

By implementing these strategies, Japan can effectively encourage the use of renewable energy sources, reduce CO2 production, and improve air quality for its citizens. These measures align with Japan's global leadership in advocating for SLCP reductions and demonstrate a commitment to a sustainable future.
