Air pollution is a pressing issue in Australia, with smoke haze from bushfires being the most visible sign. Even in years without major blazes, pockets of intense air pollution persist, particularly in disadvantaged areas. The Australian government has implemented various measures to address this issue. Under the National Clean Air Agreement, the government works with states and territories to improve air quality and reduce exposure to air pollution. They have also set national standards and regulate the import of polluting products. Local governments play a crucial role in responding to local air pollution issues, raising awareness about the impact of household activities on air quality, and administering legislation related to air quality management and reporting. Australia has established air quality standards to track pollutant levels, and while most pollutants meet these standards, particulate matter and ozone often exceed the 24-hour exposure limits. The government aims to reduce PM2.5 pollution, and while Australia has strict standards for this, its sulphur dioxide standards are relatively lax.

The Australian government has set a framework to help prioritise air quality issues and effective policy
State and territory governments are responsible for air quality in their jurisdictions and have laws and strategies in place to manage pollution, including from industrial facilities. They work with local governments, which respond to local air pollution issues and raise awareness about how household activities affect air quality. Local governments also administer legislation related to air quality management and reporting.
The Australian Government supports air quality research through the National Environment Science Program and provides policy advice on air quality. The National Environment Protection (Ambient Air Quality) Measure sets a national framework to measure and monitor Australia's outdoor air quality. The National Pollutant Inventory provides free information about noxious emissions in Australia.
Australia's air quality standards (Air NEPM) have been in place since 1998 to track air pollutant levels against science-based standards designed to limit health impacts. The NEPM applies to seven pollutants to which most Australians are exposed: carbon monoxide (CO), lead, nitrogen dioxide (NO2), ozone (O3), particulate matter (PM2.5 and PM10), and sulphur dioxide (SO2). While most of these pollutants meet the NEPM standards, particulate matter and ozone most frequently exceed the country's 24-hour exposure standards. As a result, these are Australia's main pollutants of concern, with PM2.5 being the most hazardous to citizens' health.
The Australian government is targeting particular efforts towards managing PM2.5 levels in the future. Australia has set a strict standard for PM2.5 pollution, with an annual mean concentration of 8 µg/m3, planned to be lowered to 7 µg/m3 by 2025. However, reports have found that Australia's standards for sulphur dioxide pollution are among the most lenient in the world, set at 11 times higher than the World Health Organisation's recommended limit.

The government works with states and territories to improve air quality and reduce exposure to air pollution
The Australian government works closely with states and territories to enhance air quality and minimise people's exposure to air pollution. This collaboration is facilitated through the National Clean Air Agreement (NCAA), which was established in 2015 and outlines a framework for addressing air quality issues and implementing effective policies.
Under the NCAA, the Australian government takes the lead on matters requiring a national approach. This includes setting national standards and regulating the import of polluting products. For instance, the government has targeted efforts towards managing PM2.5 levels, aiming to reduce the annual average concentration from 8 µg/m3 to 7 µg/m3 by 2025.
States and territories, on the other hand, are responsible for maintaining air quality within their jurisdictions. They have the authority to implement laws and strategies to manage pollution from various sources, including industrial facilities. Local governments also play a crucial role in responding to local air pollution issues, such as wood heater smoke, and raising awareness about how household activities can impact air quality.
To support these efforts, the government administers legislation related to air quality management and reporting. It also provides policy advice to states and territories, helping them identify and prioritise actions to improve air quality through work plans agreed upon by environment ministers. Additionally, the government supports air quality research through initiatives like the National Environment Science Program.
The collaboration between the Australian government, states, and territories is essential to effectively address air pollution and improve the health and quality of life of all Australians.

The government is targeting efforts to manage PM2.5 levels, the most hazardous pollutant to Australians' health
Australia's air quality standards (Air NEPM) have been in place since 1998 to monitor air pollutant levels against science-based standards designed to limit health impacts. The Australian government works with states and territories to improve air quality and reduce exposure to air pollution under the National Clean Air Agreement (NCAA).
Reducing PM2.5 levels is crucial as air pollution is linked to various health issues. It increases the risk of non-communicable diseases such as heart disease, stroke, dementia, type 2 diabetes, lung diseases, and cancer. Additionally, air pollution exacerbates respiratory infections like influenza and COVID-19 and may increase their severity. People with asthma are particularly vulnerable to air pollution, experiencing symptoms that indicate poor air quality.
To address PM2.5 levels, Australia's state governments and Environment Protection Agencies (EPAs) work to ensure their states meet national standards. Tasmania, for example, is known for its clean air quality, with 23 out of 24 of Australia's least polluted cities for PM2.5 pollution in 2019 located there. The coastal town of St Helens in Tasmania recorded an annual average PM2.5 concentration of just 2.4 μg/m3.
While Australia has good air quality overall, as indicated by the State of the Environment Report 2021, there is still work to be done, especially with the increasing pressure on air quality due to climate change.

The government is raising awareness about how household activities, like wood heaters, affect air quality
The Australian government is taking a range of actions to address air pollution, including raising awareness about the impact of household activities, such as the use of wood heaters, on air quality. While Australia has been found to have good air quality in general, there is still work to be done to improve it.
Wood heaters are a significant source of local air pollution in Australia during the winter months, particularly in built-up areas. Wood smoke contains a range of harmful pollutants, including particulates, nitrogen oxides, carbon monoxide, volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs). Some of these pollutants, such as particulates and formaldehyde, are carcinogenic and can lead to heart and lung disease. The use of wood heaters can also produce smoke that hangs in the air at ground level, especially on still nights, further impacting the air quality.
To address this issue, local governments are taking the lead in raising awareness about the impact of wood heaters on air quality. They are encouraging residents to consider alternative heating methods, such as gas heaters or reverse cycle air conditioners, which are more efficient and do not produce wood smoke. The government also provides information on the importance of proper installation and use of wood heaters to minimize their impact on air quality.
In addition to the efforts of local governments, the Australian Government is also taking a proactive approach by setting national standards and regulating the import of polluting products. They work closely with states and territories to improve air quality and reduce people's exposure to air pollution, especially in areas where wood heaters are commonly used.
By raising awareness about the impact of wood heaters and other household activities on air quality, the Australian government is taking important steps to improve the health and well-being of its citizens, particularly those vulnerable to the effects of air pollution, including children, pregnant women, older people, and First Nations people.

The government is working to reduce the average population exposure to fine airborne particles
Australia's air quality standards (Air NEPM) have been in place since 1998 to monitor air pollutant levels across the country against science-based standards designed to limit health impacts. The Australian government has set a national framework to measure and monitor the country's outdoor air quality. The National Pollutant Inventory provides free information about noxious emissions in Australia.
In 2015, Australia established a National Clean Air Agreement (NCAA), agreed upon by all Australian environment ministers, which sets out a framework for prioritising air quality issues and effective policy. The Australian government works with states and territories to improve air quality and reduce people’s exposure to air pollution under the National Clean Air Agreement. The government has a role in setting national standards and regulating the import of polluting products.
The government has set a goal to reduce the national ambient air quality standard of PM2.5 air pollution to an average of 7µg/m3 annually by 2025, down from 8µg/m3. However, many parts of Sydney and Wollongong exceed this level, especially in more disadvantaged areas.
To reduce the average population exposure to fine airborne particles, the government could take a new approach, as suggested by researchers. A report by the Centre for Safe Air has found that reducing the average population exposure to fine airborne particles (PM2.5) by a modest and highly achievable 5% could save more than 360 lives and A$1.6 billion a year.
The Australian government is targeting particular efforts toward managing PM2.5 levels in the future. Tasmania, for example, is Australia's cleanest state for air quality, with 23 out of 24 of the country's least polluted cities for PM2.5 pollution during 2019.
