Future Estimation of Energy Consumption and Co2 Emissions for the Analysis of the Possibility Achieving 2050 Carbon Neutrality in the Japanese Household Sector

Key Points

• The research aims to estimate future energy consumption and CO2 emissions in Japan's household sector by 2050.
• Developed a model for estimating future energy consumption and CO2 emissions.
• Analyzed the baseline scenario (BAU) for energy consumption and emissions until 2050.
• Calculated percentages of reduction in energy consumption and CO2 emissions compared to 2013.
• Estimated energy consumption of 1,136 PJ under the BAU case, a 53.4% reduction from 2013 levels.
• Projected CO2 emissions of 10.18 Mt-CO2, a 94.1% reduction from 2013 levels.
• Energy use and emissions will not reach zero despite achieving current policy targets.
