Figure 3-8. China’s Energy-Related CO2 Emissions by Sector, China Energy Outlook’s 2050 Continuous
Improvement Scenario (2015-2050)
CO2 emissions from the transportation sector peak by 2035, but its share of total CO2 emissions
grows from 11% in 2015 to 28% in 2050. Growth in transport CO2 emissions is driven by rapid
increase in demand for freight transport and its continued reliance on fossil fuels, while the
growth in passenger transport demand is partially offset by electrification coupled with an
increasingly decarbonized power system.
For the building sector, CO2 emissions peaks around 2030, but its share of total CO2 emissions
does not decline until 2045. In 2050, the share of CO2 emissions from the building sector is 21%,
the same level as in 2015. Continued efficiency improvement across all building end-uses, rapid
fossil fuel switching for heating, a major energy consuming end-use, and rapid electrification of
the building sector all contribute to the decline in building CO2 emissions.
