Abstract

地方分権化が進み,都市計画における市町村の役割が非常に高まっている.低炭素社会を実現していくためには,各市町村が都市の低炭素化の実態を把握したうえで,都市計画マスタープランにおいて適切な政策を掲げていく必要がある.本研究では,都市ごとの一人当り自動車CO<sub>2</sub>排出量の変遷を最新のデータを踏まえ明らかにした上で,経年的比較が可能なモデルの構築を通じその要素を把握し,都市マスにおける政策の構成要素との対応関係をみることで,政策方向性を検討した.分析の結果,都市の一人当り自動車CO<sub>2</sub>排出量は一部で減少に転じたことが分かった.排出量を決める要因として人口密度や都市構造以外に,自家用車保有率が強く影響を及ぼしており,これらの要因を都市計画マスタープランの中で取り上げていくことの一層の重要性が示された.

Under the recent progressive trend toward decentralization, the role of local governments related to city planning is becoming more important. Realizing a low-carbon society necessitates the advocacy of an appropriate policy for the municipal master plan considering how much automobile CO<sub>2</sub> emissions each local government can allow. In this study, we examine the policy in the future using the following analysis: 1) calculating automobile CO<sub>2</sub> emissions in 38 cities based on the latest data; 2) clarifying the factors of automobile CO<sub>2</sub> emissions by the regression model, to which time-series analysis can be applied; and 3) confirming correspondence of the factor of policy in municipal master plan from the regression model. Results show that automobile CO<sub>2</sub> emissions switched to a decreasing trend from 2005 in some cities. Furthermore, results revealed that not only density and urban layout, but also the private car ownership rate influences automobile CO<sub>2</sub> emissions.
