I mean, it’s not as if India, China, Indonesia and the USA are causing global pollution.
The problem is that per capita Australia produces double the CO2 that China does and 6 times the amount India does, it sounds crazy, but poor people don't use as much as rich affluent citizens. So in order to reduce the carbon footprint in those countries you would create some huge humanitarian issues by removing what little access the poorer population has to modern services. Where in Australia the impost is far less as those at the middle and top are excessive consumers of energy and CO2 producing goods.
Simple way of illustrating it, Australia has 1.8 cars per household, China has 1 car between 3 households. In India the figure is lower than 1 car per 11 households.
Once you get the handle on those figures it is quite clear we produce more pollution than we should, ie for comfort, fun, pleasure, whatever, while those other countries are producing pollution just to sustain population. What that means is they have almost no way to reduce the figure in reality without causing humanitarian disasters.
