Interest in co-benefits—the multiple benefits from mitigating climate change while addressing other sustainability challenges—has grown as policymakers seek to lower the costs of decarbonization. Much of this interest stems from data-driven models that quantify how much improved air quality, better health, and other co-benefits can offset those...

セメント産業は、世界で3番目に大きなエネルギー消費産業で、2番目に大きなCO2排出産業である。本事業は、インドネシアのバンテン州と西ジャワ州の２つの州にまたがって、都市間連携と民間連携を通して、セメント産業の脱炭素化を、サプライチェーン全体を視野に入れたCO2排出削減を通して実現する可能性を調査するものである。具体的には、①産業廃棄物のセメント原燃料化、②一般廃棄物の燃料化、③都市間連携を通した廃棄物管理の向上、④セメント工場への省エネ技術の導入、⑤セメント原燃料化推進に係る制度構築支援に取り組み、対象都市に様々なコベネフィットを提供することを目指した。

Balancing human activities and ecosystem health is critical amid increasing biodiversity concerns. This study explores the relationship between food provision and habitat quality in bioproduction systems in the Philippines, focusing on the Pagsanjan-Lumban Watershed (PLW) and the Baroro Watershed (BW). Using the TerrSet Land Change Modeler for LULC...

Although the performance of firefighting agents is high, they are not always cost-effective in all situations. However, there are cases where the cost-effectiveness is considered to be sufficiently high, such as aerial firefighting, extinguishing deep peat fires, and emergency firefighting before important events. In order to use the firefighting...

This policy brief examines the implications for ASEAN Member States (AMS) of the European Union’s Carbon Border Adjustment Mechanism (CBAM) and suggests an overall direction for responses. The EU’s CBAM aims to minimize carbon leakage and the loss of the EU’s trade competitiveness due to its more ambitious climate mitigation policies, particularly...

IGES's ASEAN NDC Database compiles the key elements of the Nationally Determined Contributions (NDCs), which are submitted by the ASEAN member states to the United Nations Framework Convention on Climate Change (UNFCCC). ASEAN member states are Brunei Darussalam, Cambodia, Indonesia, Lao DPR, Malaysia, Myanmar, Philippines, Singapore, Thailand and...

本ガイドブックについて 使い捨てプラスチックの消費を削減するには、人々の行動を変えることが重要です。 本ガイドブックでは、「 行動インサイト」（人々の行動や意思決定の特徴を活かし、自然に望ましい行動を促す手法）を活用することで、より効果的に行動変容を促進する方法を紹介しています。 特に、インドネシア、フィリピン、タイ、ベトナムの4カ国で実施されたプロジェクトをもとに、具体的な取り組みや得られた学びを共有しています。これらの国々では、地域の教育機関が中心となり、学生や地元の商店と協力しながら、革新的なアプローチを実践しました。 実践の足掛かりとして 本書には、行動インサイトを活用した施策（行動対策）の設計・実施を支援するための 実践的ガイドも含まれています。これを活用することで...

This assessment explored the extent to which Timor-Leste’s nationally determined contribution (NDC) and national adaptation plan (NAP) align with the outcomes of the first global stocktake (GST), using a systematic review based on a structured checklist. The alignment between the NDC and GST outcomes on mitigation was limited, as Timor-Leste’s NDC...

The outcome of the first Global Stocktake (GST1), concluded at COP28, is expected to firmly inform countries’ next nationally determined contributions (NDCs), due in early 2025, so as to ensure that global efforts are on track to achieve the goals of the Paris Agreement. Taking Malaysia as a case study country, the objective of this study is to...

Coastal cities in Vietnam are increasingly impacted by rapid environmental changes and the growing frequency and magnitude of hydrometeorological hazards, such as extreme precipitation and droughts. One of the most significant challenges posed by climate change is the imbalance of water resources availability between the wet and dry seasons. Both...
