Results of Survey on the Actual Conditions of Carbon Dioxide Emissions from Residential Sector in FY2020 (Final Figures)

The Ministry of the Environment (MOE), Japan, has been conducting the "Survey on the Actual Conditions of Carbon Dioxide Emissions from Residential Sector" since FY2017 in order to obtain detailed information on carbon dioxide (CO2) emissions from households and basic data to contribute to the planning and formulation of global warming countermeasures. MOE Japan has compiled the results of the FY2020 Survey on the Actual Conditions of Carbon Dioxide Emissions from Residential Sector.

 

Annual CO2 emissions were 2.88 t-CO2 per household, an increase of 5.9% from the previous year. MOE Japan analyzed the increase, and it was revealed that while the increase can be attributed to the impact of COVID-19 (an increase in time spent at home), there was also a decrease due to the widespread use of energy conservation.

 

MOE Japan expects many people and organizations such as local governments, universities, and business operators to use the survey results towards decarbonization in the residential sector. In addition, MOE Japan will continue to conduct this survey and promote the use of the survey results to enhance countermeasures.

 

 

- Main results (composition ratio of annual CO2 emissions per household by energy type / its transition)

 

Annual CO2 emissions per household were 2.88 t-CO2, with electricity use accounting for the largest share at 65.3% (Figure 1).

(Note) The survey covered one year from April 2020 to March 2021.

 

Annual CO2 emissions per household in FY2020 decreased by 0.32 t-CO2 per household compared to FY2017, when the survey was launched, and increased by 0.16 t-CO2 per household compared to FY 2019 (Figure 2).
