Asked in Australia in WW2Global WarmingAustralia
Does Australia use the highest amount of CFC gases per person?

I don't have info about CFC gases in general, but I have lots of CO2 data so I'll answer with respect to that. Australia's per capita emissions in 2004 were 4.5 times the global average, just BELOW the U.S., however, CO2 usage in Australia is growing faster than the U.S. and its usage is much less energy efficient than the U.S. Australia has only 0.32% of the world population, but contributes 1.43% of anthropomorphic CO2 emissions (from human activities). On average, each person in Australia and the US now emit more than 5 tons of carbon per year. While China may have just passed the U.S. in total emissions, each person there still emits only 1 ton per year on average. The US and Europe still account for more than 50% of the total accumulated global emissions over the last 200 years, while China accounts for less than 8%. Australia's carbon intensity of energy (amount of carbon burned as fossil fuel per unit of energy) is 20 per cent higher than the world average, and 25 to 30 per cent higher then the USA, Europe and Japan. Therefore, the energy efficiency of fossil fuel use is significantly lower in Australia than in these other developed countries. Australia's carbon intensity of GDP (amount of carbon burned as fossil fuel per dollar of wealth created) is 25 per cent higher than the world average. It is a little higher than the USA and nearly double that of Europe and Japan. Therefore, the overall carbon efficiency of the economy, per unit of fossil fuel used, is about half that for Europe and Japan. Over the last 25 years, the average growth rate of Australian emissions was approximately twice the growth rate for world as a whole, twice the growth rate for the USA and Japan, and five times the growth rate for Europe. The rate of improvement (decline) in the carbon intensity of GDP for Australia is lower than in the USA and Europe.
