The global trade of solar photovoltaic (PV) products substantially contributes to increases in solar power generation and carbon emissions reductions. This paper depicts global PV product trade patterns, explores emissions reduction potential, and evaluates the impeding effect of tariff barriers on global PV product trade and emissions reductions...

新型コロナウィルス（ COVID-19 ）による社会・環境・経済への広範な影響を受け、政策立案者にはプラネタリー・ヘルス（地球の健康）を取り戻すことが求められている。 地球環境戦略研究機関（ IGES ）による新型コロナに関するポジションペーパー 3.0 は、健康な地球を目指し、実現可能なアクションについて提案し、野心的な政策立案を支援することを目的としている。 本ペーパーでは、「プラネタリー・ヘルス」と「ワンヘルス」の基本概念を紹介した後、グリーンイシューである生態系関連、そしてブルーイシューである水関連の提案を行い、さらに、ブラウンイシューである気候変動やグレーイシューである大気汚染の問題に対処するための経済刺激策のモメンタムを適切に維持する方法を検討する。最後に...

COP26 に向け、多くの国がカーボンニュートラルやネットゼロ、またはそれに近い野心的な目標を掲げた。これまで目標の多くは、二酸化炭素削減（CO 2 ）に焦点が当てられてきた。将来世代が温暖化による最悪の事態を避けるため、長期的にCO 2 の大幅削減を目指すのは当然である。一方で、CO 2 削減より迅速に気候変動を緩和できる可能性として、メタンなど短寿命気候汚染物質（SLCP）削減の重要性への認識も高まっている。 グローバルメタン誓約や、SLCP削減に取り組む国際パートナーシップ（CCAC）の新戦略等、今回のCOPに合わせ、米国やEUが旗振り役となり加速した国際社会のメタン排出削減の動きを紹介する。

This article asks how to achieve food waste prevention in Asia from a governance perspective by looking at Japan, Thailand, and Vietnam as case studies. Aligning stakeholders behind preventive measures on food waste requires a context-appropriate mix of hierarchical, market, and network modes of governance. This article analyzes current food waste...

The ASEAN State of Climate Change Report (ASCCR) provides an overall outlook of the state of play of climate change issues in the ASEAN region. ASCCR is also a forward-looking report, which includes recommendations on making the transition toward 2030 and on to 2050 for both adaptation and mitigation, considering ASEAN’s development context and the...

Intensifying ecological crises, such as climate change, the melting Arctic, and uncontrolled destruction of habitat and biodiversity, are increasingly exposing the shortcomings of resource-intensive development models. One of the concepts helping policymakers steer a course change is sustainable consumption production and consumption (SCP). A...

In this discussion paper, we demonstrate why and how co-innovation can serve as a critical enabler of a bilateral Japan-India partnership on hydrogen technologies. We argue that more than conventional approaches to technology transfer, co-innovation places a premium on the role of multi-stakeholder collaboration in triggering the transition from...

The United States began liberalizing its wholesale and retail electricity market to lower costs, increase efficiency, and curb oil imports in the 1990s. Reductions in carbon dioxide (CO 2) were a possible desirable side effect of these reforms. In recent years, concerns over climate change have prompted state governments in the United States to...
