兵庫県内の事業所を対象とする質問票調査を踏まえて、事業所における屋根上太陽光発電(PV)の導入状況と導入障壁を分析し、その克服策について検討した。まず、事業用電力の調達価格の分布から、多くの場合において太陽光発電の導入による自家消費が経済的なメリットを持ちうることを確認した。また、2021年8月時点で既にPVを導入している事業所は22%であり、導入していない事業所のうち6割以上は空き屋根スペースが十分にありPVの導入可能性があることが分かった。

また、空き屋根スペースが十分にある事業所においても、PV導入への関心が無い、屋根の状態が悪い、などPV導入の障壁となりうる状況がまちまちであり、障壁に応じたきめ細やかな対応が重要であると考えられる。潜在的な導入先を3つのセグメントに分け...

温暖化に伴う水害の激甚化を受けて、地方自治体において防災・減災対策と適応策を統合し、適応能力と感受性により構成される脆弱性を低減させることが急務である。しかし、適応能力は多様な社会経済的な要素を含むため、政策上どの構成要素が重要であるかに関する包括的な検討は限定的である。そこで、本稿は、アンケート調査を実施し、地方自治体の現在の防災対策実施状況(ハード・ソフト・転換策の合計44対策)と各対策に関する将来の適応策の必要性認識に基づいて適応能力と感受性の構成要素の重要度を評価した。結果として、重要度が高く評価された適応能力要素は、地域コミュニティの「インフラ」(防災用)、「教育」(自主避難判断力、危険認知度)、「情報」(監視警戒力、情報伝達力)、「コミュニティガバナンス」(避難誘導力)、並びに...

Japanese companies have pioneered the development of a large number of low-carbon technologies (LCTs). As a rapidly expanding economy with burgeoning energy requirements, India offers a significant potential market for Japanese LCTs. The industry sector in India accounts for a significant share of commercial energy use and hence carbon dioxide (CO2...
