If China as the world's biggest polluter doesn't address it, then Australia could go back to living in mud huts and walking everywhere and the world may get an extra couple of days before the temp has gone up 1.5C. Woot.
The lesson we should be taking from this is countries should push back against China, that if they won't do their share (especially after they've f’ed the world over here), then they'll cop the hit of bringing industries back onshore or setting up elsewhere in countries that will take climate change into account.
I find that misleading.
- China emits about 10,357 million metric tons per year with a population of 1.4 billion
- The United States emits 5,414 million metric tons of carbon dioxide emissions per year with a population of 329 million
In other words, per capita each person in China emits 7.4 metric tons of carbon dioxide per year. The US emits 19.5 per capita.
Emissions per capita is not a perfect rating of how much a country is doing to limit carbon emissions, but it is probably a better marker than total emissions regardless of population. Admittedly Chinese rates of carbon emissions are growing at a faster rate due to its growing economy. But try pushing back against the US by telling them they need to reduce carbon emissions caused by fossil fuels and industry and see where that gets you.
Compare both countries to India which although it emits about 2,274 million metric tons per year, has a population of 1.35 billion. Per capita this is 1.69 metric tons per year.
