2.3.2 Total carbon footprints
The picture of carbon footprints changes again when you consider total CO2 emissions for different countries rather than emissions per person. Table 4 shows that by 2011 China had become by far the greatest total emitter of CO2, followed by the USA and India. In terms of consumption-based emissions too, the three greatest CO2 emitters were China, the USA and India (CCC, 2013).
Table 4 Total territorial carbon dioxide emissions for selected countries (CDIAC, 2015; Global Carbon Atlas, 2016)
|Country||Total CO2 (2011), million tonnes per year (rounded)||Total CO2 (2015 est.), million tonnes per year (rounded)|
|World average (mean)||150.8||(World total 36 292)|
Figure 10 shows more of the same information updated using estimations to 2015, when China, USA and India emitted half of the world’s CO2.
