The Role of Sub-National Actors in Climate Change Policy. The Case of Tokyo
Tokyo is known as a pioneer throughout the history of Japan’s environmental policy, often being compared to California in the United States or Paris in France. Following the global trend of growing local initiatives tackling climate change, Tokyo introduced a cap-and-trade scheme in 2010 ahead of a national implementation.
The Tokyo Cap-and-Trade Program is the first of its kind that regulates CO2 emissions from all business sectors, where energy consumers are defined in terms of the business establishments they own. Tokyo’s initiative is largely seen as a reaction to the modest national commitment, following the tradition of center-local rivalry.
This study first explains the centre-local relationship in the history of Japan’s environmental governance. It then analyzes the development of the Tokyo’s flagship climate policy and its implications for national and other sub-national governments in Japan. The tactics used by the Tokyo Metropolitan Government to overcome business opposition typically seen in the introduction of GHG control, and future policy challenges are also discussed. The study finds that Tokyo’s policy encourages behavioral changes and technological improvement in the business sector, going a step beyond the existing culture of energy conservation in Japan. An emission trading scheme is often associated with the collapse of carbon markets and the “money game”, rather than a practical tool to reduce CO2 emissions, but the Tokyo Cap-and-Trade Program has demonstrated a policy impact that recasts such an image. A known case of policy diffusion to Saitama prefecture, an immediate neighbor of Tokyo with the fifth largest population in Japan, is also discussed to elaborate on the potential domestic diffusion of the policy.

Center for Asian Studies
Asia is a nerve center for multiple global economic, political and security challenges. The Center for Asian Studies provides documented expertise and a platform for discussion on Asian issues to accompany decision makers and explain and contextualize developments in the region for the sake of a larger public dialogue.
The Center's research is organized along two major axes: relations between Asia's major powers and the rest of the world; and internal economic and social dynamics of Asian countries. The Center's research focuses primarily on China, Japan, India, Taiwan and the Indo-Pacific, but also covers Southeast Asia, the Korean peninsula and the Pacific Islands.
The Centre for Asian Studies maintains close institutional links with counterpart research institutes in Europe and Asia, and its researchers regularly carry out fieldwork in the region.
The Center organizes closed-door roundtables, expert-level seminars and a number of public events, including an Annual Conference, that welcome experts from Asia, Europe and the United States. The work of Center’s researchers, as well as that of their partners, is regularly published in the Center’s electronic journal Asie.Visions.
The Oceania Factor in France’s Evolving Indo-Pacific Strategy
This paper examines the two-way relationship between France’s Indo-Pacific strategy and developments in Oceania. Oceania was not a priority in the initial years of France’s Indo-Pacific strategy, as the region was largely treated as secondary to major strategic hotspots and key partnerships, while overseas territories were primarily handled as domestic issues and recipients of a top-down strategy.
France’s View: From Diplomacy to Public-Private Action
France has emerged as the EU’s IMEC forerunner, combining port infrastructure, diplomatic alliances and public-private cooperation. With Marseille Fos at its core, the country brings a strategic hub for logistics, energy and digital connectivity to the corridor.
Trump II, the Crisis of the Rules-Based Order and Europe’s Indo-Pacific Strategy
This article examines the implications of Trump II for Europe’s engagement in the Indo-Pacific. The piece contends that Trump II is accelerating the erosion of the rules-based order and undermining the relevance of the Free and Open Indo-Pacific (FOIP) concept, while forcing Europe to refocus on its own continental security amid US retrenchment. Paradoxically, these very constraints create conditions for a more autonomous, pragmatic, and explicitly interest-driven European engagement in the Indo-Pacific, rather than outright withdrawal.
China and Trade in Critical Raw Materials (CRMs)
Critical raw materials (CRMs) have become central features of a new dynamic in global power politics, with China now wielding considerable leverage. Amid rising regional and global uncertainty, resource security is back in the spotlight as a key determinant of sovereignty and national security for Europe, its allies and its partners. The very survival of key, even vital industries, from automotive to aerospace to health to energy to defense, is at stake.
