What You'll Learn
Australia's air quality is ranked among the cleanest in the world
Australia is known for its clean and diverse environment, from its cool coastlines and lush tropical rainforests to the rich red earth of the Outback. The country's air quality is ranked among the cleanest in the world, with its cities consistently being ranked as some of the most liveable. According to the Air Quality Index, Australia is ranked as the ninth cleanest country in the world for air quality.
In 2019, Australia ranked as the 10th cleanest country out of 98 countries in IQAir's World Air Quality Report, with a country-wide average PM2.5 level of 8.0 μg/m3. This level is slightly more polluted than that of Canada, New Zealand, and Sweden but cleaner than the United States, the United Kingdom, and France. Australia's air quality remains low year-round, but the country is vulnerable to short-term extreme pollution spikes due to bushfires and dust storms, which can temporarily result in some of the world's worst air quality.
Despite its overall positive results, Australia still faces air pollution problems, particularly in its major cities. Sydney, for example, has ranked last among Australian cities for air quality, falling behind London. Additionally, a Greenpeace report found that Australia's standards for sulphur dioxide (SO2) pollution are among the most lax in the world, allowing domestic power stations to emit higher levels of sulphur dioxide emissions than those in China and the European Union.
However, Australia has strict environmental laws and recognizes the importance of addressing climate change. The country has committed to achieving net-zero emissions by 2050 and reducing greenhouse gas emissions to 43% below 2005 levels by 2030. Australia also has the highest uptake of solar energy globally, with around one-third of homes equipped with rooftop solar panels. These initiatives contribute to maintaining the country's clean air and enhancing the quality of life for its residents.

Australian cities are some of the most liveable
Australia is widely recognised as one of the cleanest countries in the world, with its cities ranking among the most liveable. The country's air quality is consistently ranked among the best globally, and its diverse environment, which includes cool coastlines, lush tropical rainforests, and the Outback, is known for its cleanliness.
According to the Air Quality Index, Australia ranks highly for air quality, with its beautiful climate and clean environment encouraging a healthy outdoor lifestyle. The country has also been ranked third in the world for cleanliness according to the Environmental Performance Index, with the Australian government placing significant importance on cleanliness, environmental awareness, and public health.
The country's renewable energy sector is thriving, with Australia being the world's seventh-largest producer of solar energy and boasting the highest uptake of residential solar energy globally. Around one-third of Australian homes have rooftop solar panels, and the country has set ambitious targets for reducing greenhouse gas emissions and achieving net-zero emissions by 2050.
Australian cities consistently rank highly on liveability indexes. According to the Economist Intelligence Unit's Global Liveability Index 2023, Sydney and Melbourne were ranked as the third and fourth most liveable cities in the world, respectively. Perth and Adelaide also performed well, tying for 12th place. Additionally, a report by HouseFresh found that six out of nine cities experiencing 365 'good air days' a year were in Australia, with Perth, Wollongong, Sydney, Newcastle, Adelaide, and Canberra all making the list.
The country has implemented various strategies to maintain and improve its air quality. Australia's air quality management system is governed at both the national and local levels, with the National Environment Protection Measures (NEPM) established in 1998 to track air pollutant levels against science-based standards. The government has also established the National Clean Air Agreement (NCAA), which sets a framework for prioritising air quality issues and effective policy.
Australia's commitment to cleanliness and environmental sustainability, coupled with its high liveability rankings, makes it a desirable destination for those seeking a healthy and enjoyable lifestyle. The country's efforts to reduce pollution and promote renewable energy further contribute to its reputation as a clean and liveable place.

Australia has the highest uptake of solar globally
Australia has been recognised as one of the cleanest countries in the world for its air quality. In 2021, the Australian renewable energy industry accounted for 32.5% of Australia's total electricity generation. The country is also the world's seventh-largest producer of solar energy.
The state governments have also taken initiatives to encourage the uptake of solar energy. For instance, in 2018, the Queensland government introduced the Affordable Energy Plan, offering interest-free loans for solar panels and solar storage. In South Australia, a solar feed-in tariff was introduced for households, along with an educational program that involved installing solar PV on the roofs of major public buildings.
The rapid growth in Australia's clean energy mix is due to an abundance of sunshine, lower energy bills, and feed-in tariffs. The Clean Energy Council has led calls for a national Home Battery Saver Program to provide more Australians with cost-of-living relief and the flexibility of storing, using, and trading lower-cost electricity generated at home.

Australia's renewable energy industry
Australia is ranked among the top 10 cleanest countries in the world for air quality. The country's clean climate and environment encourage a healthy outdoor lifestyle. Sydney, Melbourne, Perth, and Adelaide are among the world's most liveable cities.
The Australian renewable energy industry is an important contributor to the country's clean and green image. The industry accounted for 32.5% of Australia's total electricity generation in 2021, with renewable electricity generation more than doubling over the last decade. Solar and wind have been the primary drivers of this growth, with small-scale solar generation growing 17% in 2023 and wind generation growing 6% in the same year. Large-scale solar generation has also seen rapid expansion, growing from negligible levels before 2016 to 6% of all Australian electricity generation in 2023.
The Australian Renewable Energy Agency (ARENA) was established in 2012 to improve the competitiveness and supply of renewable energy technologies and encourage innovation in the industry. The government has also introduced policies to reduce greenhouse gas emissions and increase energy security. Australia has set targets for emission reductions and is exploring various climate change strategies, including renewable energy expansion and energy efficiency programs.
The Solar Sunshot program, announced in March 2024, is a $1 billion fund that provides grants and production credits to manufacturers of solar panels, with the aim of increasing domestic production. This scheme is part of a plan to provide jobs for workers currently employed in the coal industry. Australia has the highest uptake of residential solar energy globally, with around one-third of homes having rooftop solar panels.
However, there are disputes about the level of subsidies paid to the fossil fuel industry in Australia, with arguments that these subsidies act as impediments to investment in renewable energy resources. Despite this, the renewable energy sector in Australia is attracting major investment, and the country is the world's seventh-largest producer of solar energy.
