Australia had the highest per capita nitrogen oxides (NOx) emissions of all OECD countries in 2021, at nearly 109 kilograms per person. Since 1995, Australia has generally had the highest NOx emissions per capita of OECD countries, except in the mid 2000s, when Luxembourg's per capita emissions increased to roughly 120 kilograms per person. Unlike many OECD countries, Australia's per capita NOx emissions have increased since 1990. In comparison, OECD countries such as the United Kingdom and United States have experienced reductions of more than 70 percent.
