Plastic pollution is a growing challenge in Southeast Asia, where rapid urbanisation and rising consumption are driving sharp increases in plastic waste. While traditional regulations such as plastic bans and information campaigns are important, they often fail to shift deeply ingrained consumption and waste management habits on their own. This new...

Non-economic loss and damage (NELD) associated with climate change is increasingly recognized as a critical yet under-assessed dimension of climate risk, particularly in vulnerable regions such as Africa. This study presents an analytical framework for synthesizing evidence from a systematic literature review conducted under the ASCEND initiative...

This discussion paper introduces the conceptual foundations and analytical framework of the Asia-Pacific Climate Security (APCS) briefing note series. It situates climate security within an evolving geopolitical context marked by intensifying climate impacts and growing challenges to multilateral cooperation. The paper examines how climate change...

This discussion paper analyzes the impacts of global warming on maritime security in the Asia-Pacific region, focusing on both geopolitical transformations and legal implications arising from climate-induced oceanic changes. It highlights how rising sea levels, intensifying marine disasters, and shifting ecosystems are reshaping security dynamics...

This paper examines the complex relationship between climate change and food security in the Asia-Pacific region. It demonstrates how climate change disrupts food systems through impacts on crop yields, fisheries, and supply chains, while interacting with socio-economic inequalities, governance failures, and competing resource demands to produce...

This discussion paper explores the concept of climate-induced mobility in the Asia-Pacific region and its implications for security, governance, and policy development. It highlights the growing recognition of climate mobility in international and regional policy frameworks, while emphasizing the absence of a comprehensive global legal regime to...

2025 年 1 月の第 2 次トランプ政権発足以来、米大統領府は、'\リ協定脱退や石炭産業活性化に関する大統領令を相次いで発出し、米環境保護庁(EPA)は、温室効果ガスの影響に関する危険性認定を含む約 30 項目の環境規制の見直しを公表するなど、トランプ政権は、バイデン政権が進めてきた脱炭素政策からの全面的な見直しを目指しており、米国の環境、気候変動政策は大きく転換している。 また、トランプ政権は国連組織等の国際機関への拠出の一時停止や見直しを行うとともに、国務省、EPA、USAID をはじめとする連邦政府組織の見直し、大規模な人員削減を実施。USAID の機能停止により、世界各地での支援が停止するなど、世界中に影響が広がっている。 本業務では、こうした米国における環境...

本研修は，2025 年1 月に実施したエジプトがパリ協定の下で強化された透明性枠組み「enhanced transparency framework (ETF)」に沿った国内システムを確立することを企図した国別研修の続編として，実施された．気候変動はエジプトを含む全世界の脅威であり，エジプトも加盟する気候変動枠組条約の下，2016 年に発効したパリ協定では，全ての国が「国が決定する貢献」（Nationally Determined Contributions; NDC）を作成し，自身が表明した温室効果ガス(GHGs)削減・抑制目標に沿って取組を進める必要がある．また，その進捗・結果をモニタリングし，2 年毎に透明性報告書（Biennial Transparency Report; BTR...

This discussion paper examines whether the securitisation of climate change can accelerate the transition to net-zero emissions in the Asia-Pacific region. It argues that framing climate change and energy transition as national security concerns can elevate policy urgency and mobilise resources to address systemic risks, including energy insecurity...
