A study on municipal CO₂ emissions from household and passenger-car

家庭と乗用車から生じる市区町村別CO2排出量に関する考察

This study aims to estimate household CO₂ emissions and passenger car CO₂ emissions of municipalities in Japan to compare the characteristics of cities for low carbon societies. Revised estimation methods were developed from the standard shown in the 2017 version national manual. Household CO₂ emissions by municipality were estimated reflecting the difference between single-family households or two or more households and the difference between detached houses or apartment houses in 10 regiions. Passenger car CO₂ emissions by municipality calculated with road traffic census were edited according to its reliability. .As a result, it was found that emissions are small in metropolitan cities with a high proportion of household living in apartment houses, and that emissions are high in suburbs of the Chugoku region in addition to the Hokkaido region and Tohoku region.家庭CO₂排出量と乗用車CO₂排出量を合わせた家庭におけるCO₂排出量を全国市区町村別に推計し、それぞれの特徴を比較考察した。その際に、2017年版の策定マニュアルに示される標準的な手法よりも詳しく、10地域別に戸建か集合かおよび単身世帯か2人以上世帯の違いを反映した市町村別家庭CO₂排出量を新たに求め、道路交通センサスの走行距離等とその信頼性を考慮した乗用車CO₂排出量を整理した。その結果、集合住宅居住割合の高い都市で排出量が少ないこと、世帯当たり排出量が高い中国地方等の郊外で排出量が多いことが分かった。
