World CO2 emissions

The total was about 36 billion tonnnes CO2 in 2019 [1].
As the world population is 7.9.billion, this is 4.6 tonnes CO2 per person per year.

UK greenhouse gas emissions

Total greenhouse gas emissions were around 930 million tonnes CO2-e per year in 2015, including imports/exports and aviation [2].
As the population is 66 million, this is 14.1 tonnes CO2-e per person per year.

China CO2 emissions

Emissions were 10.1 billion tonnes CO2 in 2018 [3].
Of these, around 13% were from net exports, based on 2014 figures [4].
This gives an adjusted value of 8.8 billion tonnes CO2.
As the population is 1.43 billion, this is 6.2 tonnes CO2 per person per year.

USA CO2 emissions

Emissions were 5.42 billion tonnes CO2 in 2018 [3].
The net CO2 transfers associated with trade were 6% (net imports), based on 2014 figures [4].
This gives an adjusted value of 5.8 billion tonnes CO2.
As the population is 327 million, this is 17.6 tonnes CO2 per person per year.
