　北九州市は、市内の温室効果ガス（GHG）排出削減目標を掲げるだけでなく、アジア地域への貢献目標も掲げている。それは、アジア地域で、2050年までに、2013年度の市内のGHG排出量の150％以上に相当する排出量の削減を目指す（以下、「150％削減目標」という。）というものである。環境国際協力に長年取り組んできた「世界の環境首都」として、気候変動対策のようなグローバルイシューにも市内外で積極的に貢献していく姿勢を見せている。 　本稿は、北九州市の「150％削減目標」の意義や、その目標達成に向けたアプローチを確認した上で、政策効果の「見える化」の方法論について検討を行った。「150％削減目標」が数値目標であることを踏まえ、北九州市の取り組みのうちGHG排出削減量を把握できそうなものを特定し...

Source separation plays a pivotal role in sustainable and integrated Municipal Solid Waste Management (MSWM) and in achieving a circular economy in Asia.
