I’ve included the US emissions, because they show a very important point. If we were able somehow magically to reduce our emissions to their 1980 levels, that reduction would be offset by the Chinese gains in one single year. In other words, what the US does is meaningless in global terms.
The US economy is about 14 times larger than the Australian economy. If efforts by the US are made meaningless by Chinese emissions, how stupidly pathetic are our efforts to reduce emissions via a tax on carbon dioxide?
