Australia's government sets national standards and regulates imports of polluting products
Australia's federal structure of government means that environmental issues are addressed by both the federal and state governments. The Australian Government takes the lead on issues that require a national approach, including setting national standards and regulating imports of polluting products. The Department of Infrastructure, Transport, Regional Development, Communications and the Arts, for instance, manages emissions from vehicles and shipping. The National Pollutant Inventory provides free information about noxious emissions in Australia.
The states and territories are responsible for air quality in their jurisdictions. They have laws and strategies in place to manage pollution, including from industrial facilities. They report against national ambient (outdoor) air quality standards that protect people’s health. Local governments respond to local air pollution issues like wood heater smoke. They raise awareness about how household activities affect air quality.
The Australian Government also works with states and territories to maintain and improve Australia's air quality. It administers legislation related to air quality management and reporting. It also supports air quality research through the National Environment Science Program and provides policy advice on air quality to the Australian Government.
The National Environment Protection Council administers the national Environment Protection Measures (NEPMs), which include the national ambient air quality standards and the National Pollutant Inventory. In April 2021, NEPM limits were reduced for ozone, nitrogen dioxide, and sulfur dioxide. While this is a step in the right direction, reducing the NEPM limits alone will not improve air quality without a targeted program to reduce pollution sources and minimize the exposure of the Australian population.
Air pollution is a serious issue in Australia, with an estimated 3,200 deaths per year attributed to it, at a cost of A$6.2 billion. It is the single greatest environmental cause of preventable disease and premature death in the country. Population growth, ageing, urbanization, and increasing transport and energy demands all contribute to the problem. Fine particulate matter (PM2.5) is one of the most concerning pollutants in terms of human health. While all cities have maintained a 'very good' assessment for PM2.5 since 2016, peak reported levels remain above the air quality NEPM standard in all capital cities.

Local governments address local air pollution issues, like wood heater smoke
Local governments play a crucial role in addressing local air pollution issues, such as wood heater smoke, which is a significant contributor to air pollution in Australia. Wood smoke is composed of a mixture of gases and fine particles released when wood and other organic matter burn. These particles, known as particulate matter or PM, can penetrate deep into the lungs, causing harm to the lungs, blood vessels, and heart.
To tackle this issue, local governments have implemented various strategies and regulations. They raise awareness about the impact of household activities, including the use of wood heaters, on air quality. This involves educating the public about the health risks associated with wood heater smoke exposure, particularly for individuals with pre-existing heart, vascular, or lung disease, as well as children and older adults who are more vulnerable.
In collaboration with state and tribal governments, regional air quality agencies, and community groups, local governments have access to tools and resources provided by organizations like the Environmental Protection Agency (EPA) in the United States. The EPA's Burn Wise program offers comprehensive guidance in the form of "Strategies for Reducing Residential Wood Smoke." This document outlines effective approaches, including local regulations, voluntary programs, funding mechanisms, and best burn practices, to reduce particle pollution from wood-burning appliances.
By adopting these strategies, local governments can significantly reduce the harmful emissions produced by wood heaters. This includes encouraging the use of cleaner-burning heaters that meet stringent emission standards, such as those set by the EPA for new wood stoves and other wood heaters. These standards aim to reduce particulate matter (PM) emissions and limit the release of pollutants like carbon monoxide, volatile organic compounds (VOCs), black carbon, and toxic substances like benzene.
Additionally, local governments can promote the efficient use of wood heaters by educating homeowners on following the manufacturer's instructions for heater operation. This not only ensures optimal heater performance but also helps maintain the validity of the heater's warranty. By implementing these measures, local governments actively contribute to improving air quality and protecting the health and well-being of their communities.

Australia's ageing population and increasing transport demands add to air quality risks
Australia's ageing population and increasing transport demands pose significant risks to air quality, necessitating concerted efforts to mitigate these challenges. The transportation sector is a major contributor to Australia's greenhouse gas emissions and air pollution, particularly in states like New South Wales (NSW). As the population ages and grows, the demand for transport increases, leading to more vehicles on the roads and a higher number of trips, especially in urban areas. This trend has been evident in regions like Sydney, Hunter, and Illawarra, where the average number of daily trips across all modes of transport rose by 11.8% between 2009-10 and 2019-20.
The impact of the transport sector on air quality is concerning. In NSW, transport emissions are the second-largest component of greenhouse gas emissions, with a steady increase since 2005. Petrol and diesel-fuelled vehicles are the primary sources of oxides of nitrogen (NOx) emissions in Greater Sydney, and they also contribute significantly to population exposure to fine particles. The health implications of transport-related air pollution are significant, with an estimated 1,000 to 2,550 premature deaths and 26,700 cases of cardiovascular hospitalisations, asthma attacks, and chronic obstructive pulmonary disease episodes attributed to transport emissions in 2018. The economic burden of transport-related pollution is substantial, with a total cost of A$910 million estimated for that year.
To address these issues, various strategies are being implemented. The NSW Electric Vehicle Strategy aims to increase electric vehicle (EV) sales and electrify the state's fleet, which is crucial for achieving net-zero emissions by 2050. The transition to an electric fleet can significantly reduce emissions and improve air quality. Additionally, the Australian government takes a leading role in setting national standards and regulating imports of polluting products. States and territories are responsible for maintaining and improving air quality within their jurisdictions, implementing laws and strategies to manage pollution from industrial facilities and local sources like wood heater smoke.
However, more needs to be done to address the challenges posed by the ageing population and increasing transport demands. The projected population growth in NSW by 2041 underscores the urgency of government action to manage the environmental impact of a growing number of vehicles and the demand for public transport. Continued investment in research, the development of clean energy technologies, and the implementation of policies based on scientific evidence are crucial for mitigating the risks to air quality and protecting the health and well-being of Australia's ageing and vulnerable populations.

Australia's Clean Air Plan for Sydney recommended banning wood heaters in urban areas
Australia is taking several measures to combat pollution, particularly air pollution, which has been linked to over 3,200 deaths per year in the country. The Australian government sets national standards, regulates imports of polluting products, and works with states and territories to maintain and improve air quality. Local governments address local air pollution issues, such as wood heater smoke, and raise awareness about how daily activities impact air quality.
One notable initiative is Australia's Clean Air Plan for Sydney, which aims to address the city's air pollution, dominated by human-created emissions. The plan highlights the significant contribution of residential wood smoke to air pollution, with wood heaters causing greater cumulative exposure to smoke due to frequent use. As a result, the plan recommends banning wood heaters in urban areas to improve air quality.
The Clean Air Plan for Sydney's recommendation to ban wood heaters in urban areas is a targeted approach to reducing pollution sources and minimizing the Australian population's exposure to harmful emissions. This recommendation is supported by research indicating that wood heaters significantly contribute to overall population-weighted PM2.5 levels in the NSW Greater Metropolitan Region. Phasing out wood heaters in urban areas is expected to reduce smoke pollution and improve the health and well-being of residents.
The University of Wollongong's Centre for Atmospheric Chemistry, led by Professor Clare Murphy, played a pivotal role in developing the Clean Air Plan for Sydney. Their research underscores the significant impact of residential wood smoke, hazard-reduction burns, traffic emissions, and industrial and power generation emissions on air pollution in the region. The plan calls for legislation and public awareness campaigns to eliminate wood heater use in urban areas and reduce their use in specific regional areas.
While encouraging residents to move away from wood heating has been challenging, a buy-back scheme implemented in Tasmania successfully reduced wood heater usage. The Clean Air Plan for Sydney aims to address this issue through a combination of legislative measures and educational initiatives, demonstrating Australia's commitment to exploring various strategies to mitigate air pollution and protect the health and environment of its citizens.
