　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...

In view of the growing recognition of the role of non-state actors as agents of implementation of addressing climate change under the Paris Agreement, this study sheds light on the measures taken by urban cities in developing countries. Beyond the process of formulating climate action plans reviewed in previous studies, this study aims to identify...

The circular economy transition along global value chains provides levers that can curb raw material use, preserve biodiversity, and reduce pollution, including the emission of greenhouse gases (GHGs). While the transition to circularity is building momentum, several systemic barriers continue to exist. This policy brief presents eight proposals...

This rapid assessment aimed to identify and quantitatively estimate the waste management infrastructure gaps for plastic waste in the Philippines to provide a baseline for investments required to bridge and close the gaps. The paper was developed by the Institute for Global Environmental Strategies with support from UN-Habitat and Save Philippine...

While raising awareness is critical in providing information on the growing plastic crisis and explaining why current behavior needs to change, higher awareness does not always lead to behavior change. This paper aims to explore these barriers and motivations, and offer recommendations to promote behavior change at the community level. This paper...

This paper presents the different EPR models and its application to plastic waste management in selected Asian countries, and looks into then approved EPR bills, proposed EPR mechanisms from the private and non-government sectors, and existing EPR-similar schemes from other organizations. The paper discusses recommendations for a collaborative...

Purpose Takakura Composting Method (TCM) is a simple and cost-effective aerobic composting method using locally available materials and has been widely introduced in Indonesia and other countries. This study tracked the progress of scaling the TCM up to 1 tonne/day of organic waste input at the decentralised composting centre in Bandung City...

The Paris Agreement sets the goal to limit the global warming to well below 2 °C and preferably 1.5 °C. The recent IPCC report warned that 1.5 °C-warming may occur much earlier than expected. To meet the 1.5 °C target, global emissions of greenhouse gases (GHGs) should be net zero by 2050 or earlier. Increasing number of countries, local...

Our longing for incessant and rapid economic growth came at a cost of inefficient and wasteful use of resources and environmental pollution. The consequences are immense and far exceeding the planetary capacities to regenerate itself at such a fast pace. It became clear that a transition to sustainable societies cannot occur with our current linear...

北九州市海外水ビジネス推進協議会（KOWBA）は2020年に設立10周年を迎えた。その節目に際してKOWBAが作成した記念誌の一部として「北九州市が取り組む海外水ビジネス」を執筆した。これは「持続可能な社会への挑戦－北九州市とアジア都市との連携」（2018年7月）と「北九州における水ビジネス海外展開の歴史と発展」（2020年3月）に基づいた内容となっている。IGES北九州アーバンセンターとして北九州市の国際政策を20周年以上見つめてきた立場から、北九州市の海外水ビジネス、並びにKOWBAの役割や未来について論じている。
