According to the Global Carbon Project, rich countries account for the lion's share of historic emissions.
The United States accounts for 24.6 percent of global historical emissions, and the European Union accounts for 21.7 percent.
Australia is one of the highest per capita CO2 emissions earners in the world [according to Climate Analysis].
On a per capita basis, Australia's carbon footprint, including exports, surpasses China by a factor of 9, the US by a factor of 4 and India by a factor of 37.
The report by [aid group] Caritas Australia concluded the concerns felt by Australians on climate change outstripped other global concerns, including armed conflict or COVID-19.
Poor countries attending COP27 want rich countries to provide funds to help countries that cannot avoid or adapt to the effects of climate change.
The European Union and the United States have so far opposed such calls, fearing the huge amount of costs.
