Read the second part of my comment. It's about 10% from trade based manufacturing. Of course this is difficult to measure, but I think its safe to say the lion's share of CO2 emissions are from consumption.
> And it's not that China is producing emissions during manufacturing goods the entire world consumes. Take a look at "China: Consumption-based accounting: how do emissions compare when we adjust for trade?" and you'll see ~90% of their emissions are for consumption [2]
Still their per-capita emissions are lower, which is kind of what really matters given nations and borders are essentially a social construction, personal consumption/emissions are not.
As I mentioned previously, reducing China's total emissions would require reducing their per-capita emissions to such a low amount it would essentially be condemning much of the population to live in abject poverty (especially as large parts of the nation has not yet industrialised).
Given the far, far higher per-capita emissions of countries like the USA, Canada, Australia, Saudi Arabia etc. it wouldn't surprise me if China refused to slow economic development in order to reduce emissions.
