君津市地球温暖化対策実行計画

令和５年 8 月
君津市

はじめに地球温暖化の進行による気候変動や自然災害の頻発化・激甚化は極めて深刻な問題であり、本市においても令和元年房総半島台風等により甚大な被害を受けました。
このような気候危機等に対応するため、平成 27（2015）年のパリ協定採択をはじめ、脱炭素に向けた国際的な取組が加速化したほか、我が国でも令和２（2020）年に 2050年カーボンニュートラルの実現を宣言して以降、「グリーン成長戦略」や「地球温暖化対策計画」の策定など、脱炭素社会実現に向けた動きが大きく進展しています。
そうした中、本市では、令和３（2021）年９月に、2050 年までに温室効果ガスの実質排出量をゼロにしつつ、経済と環境が調和した持続可能な「環境グリーン都市」を目指すことを宣言し、また、令和４（2022）年３月には、君津市総合計画を策定し、５つの柱の一つとして「経済と環境が調和したまち」を掲げるなど、脱炭素社会の推進を重要な施策の一つとして位置づけました。
脱炭素の達成は大きな挑戦です。この挑戦を成し遂げ、先人たちから受け継がれてきた「君津」を次世代に継承していくとともに、さらなる発展へつなげられるよう全力で取り組んでまいります。
「第５次君津市地球温暖化対策実行計画」では、市の事務・事業から排出される温室効果ガスの排出量削減について定めた既存の「事務事業編」に加え、市域全域から排出される温室効果ガスの排出量削減について定めた「区域施策編」を新たに策定し、水と緑の保全や再生可能エネルギーの地産地消、さらなる省エネ創エネ化の促進、脱炭素につながるライフスタイルへの転換等、脱炭素への取組を加速させていきます。
結びに、本計画の策定にあたりましては、多くの市民・事業者の皆様にご意見をお寄せいただくとともに、君津市環境審議会の皆様をはじめ、関係者各位にお力添えをいただきましたことに、心から感謝申し上げます。
本計画に基づき、市民・事業者の皆様と市が一体となって、「オール君津」で環境グリーン都市の実現に向けた取組を進めてまいりますので、皆様のご理解ご協力をお願い申し上げます。
