OECC

What OECC does

Founded in 1990, OECC (Overseas Environmental Cooperation Center, Japan; 一般社団法人海外環境協力センター) is a Tokyo-based general incorporated association that operates as Japan's primary commissioned intermediary for international environmental cooperation. The organization serves as a bridge between Japanese government agencies (Ministry of the Environment, JICA) and developing-country governments, with a secondary mandate to support Japanese environmental technology companies in overseas market entry. OECC's portfolio spans roughly 15 service lines grouped into four domains: climate change mitigation (JCM project formation, GHG inventory/MRV systems, transparency frameworks, Paris Agreement/NDC support), environmental management (circular economy, 3R/waste-to-energy, e-waste, ACCP coordination), biodiversity (mangrove conservation and carbon credit support), and integrated approaches (co-benefit air-pollution reduction, OTEC, green hydrogen, fluorocarbon lifecycle management).

OECC does not develop proprietary hardware or software products. Its core capability is policy analysis, JCM methodology development, and institutional framework building for climate and environmental cooperation. Notable technical outputs include JCM methodology webinars (co-organized with IGES), the JCM/Carbon Markets Newsletter (195+ volumes), the academic journal 'Global Environmental Research,' and refrigerant lifecycle digital tracking systems deployed with the Government of Vietnam. Quantified outcomes to date include 26 supported JCM projects (representing over 10% of all JCM facility subsidy projects as of May 2024), 10,000+ amorphous transformers introduced in Vietnam and Laos, a Ulaanbaatar coal-to-gas boiler conversion delivering 37% CO2 / 63% NOx / 100% SOx / 99% CO / 100% dust reductions versus coal boilers, a 12.7MW solar sharing facility in Mongolia yielding 10,000+ tCO2 annual reduction, and approximately 400,000 tCO2 credits issued under the YAGASU Verra VCS mangrove project.

The business model is built on government-commissioned project contracts (primarily from MOEJ and JICA) supplemented by membership fees from Japanese companies, local governments, and NGOs. OECC also serves as secretariat for the JPRSI Environmental Infrastructure Overseas Deployment Platform and the Fluorocarbon Initiative, both commissioned by MOEJ. Geographic reach covers 31+ JCM partner countries across Asia, Africa, Central Asia, the Middle East, Caucasus, Eastern Europe, and Latin America. Revenue is not publicly disclosed, there is no commercial pricing model, and the organization does not sell products or services on standard commercial terms.

Core offering

OECC is a Japanese general incorporated association (非営利法人) that facilitates international environmental cooperation between Japanese government agencies, Japanese environmental technology companies, and developing country governments. It provides commissioned project services including JCM (Joint Crediting Mechanism) implementation support, capacity-building training programs, policy advisory for Paris Agreement implementation, technology transfer facilitation, and secretariat operations for environmental cooperation platforms.

Product overview

OECC (一般社団法和洋環境協力センター) is a general incorporated association providing international environmental cooperation services, not a technology product company. The organization operates as a coordination and consulting hub rather than a software platform. Its service portfolio includes JCM (二国間クレジット制度) implementation support as its core offering, complemented by climate finance training programs, OTEC (海洋温度差発電) and green hydrogen technology deployment support, transparency and MRV system building (透明性向上支援), fluorocarbon lifecycle management (フロン対策), mangrove conservation (マングローブ保全), co-benefit air pollution reduction projects (コベネフィット), and biodiversity conservation. Additional services encompass the JCM/Carbon Markets Newsletter (JCM／炭素市場ニュースレター), OECC LETTER email magazine, international training programs (国際研修), Environmental Week event coordination (環境ウィーク), and JPRSI platform secretariat operations. These services function independently rather than as modules within an integrated platform architecture.

Expansion highlights6 records

Direct peers

• SNV (Netherlands Development Organisation): Dutch development non-profit implementing clean energy, climate adaptation, and sustainable agriculture projects across Asia and Africa. Comparable non-profit international project implementation model focused on climate and environmental outcomes in developing countries.
• Climate Technology Centre and Network (CTCN): UNFCCC-affiliated technology cooperation mechanism facilitating climate technology transfer and technical assistance to developing countries. OECC has directly implemented CTCN technical assistance assignments (OTEC pre-FS for Nauru, green hydrogen in Mongolia), giving overlapping technology cooperation mandates.
• Institute for Global Environmental Strategies (IGES): Japan-based non-profit policy research institute focused on climate change, biodiversity, and sustainable development. Co-organizes JCM methodology webinars with OECC and collaborates on Article 6 implementation research, making it the closest Japanese analogue in mandate and geography.
• Carbon Trust: UK-based climate consulting organization providing advisory, certification, and program management for international climate initiatives. Overlaps with OECC's JCM, carbon market, and refrigerant management service lines under a different legal and funding model.
• International Institute for Sustainable Development (IISD): Canadian non-profit policy research organization with deep climate finance, transparency, and environmental policy expertise. Comparable as a non-profit international advisory model serving governments and IGOs on sustainability and Paris Agreement implementation.

Others

• Climate and Clean Air Coalition (CCAC): International coalition focused on reducing short-lived climate pollutants including HFCs. OECC Director Kato serves as Co-Lead of CCAC Cooling Hub, reflecting close collaboration, though CCAC is a coordinating body rather than a direct implementation peer.

Regional players

• Korea Environmental Industry & Technology Institute (KEITI): Korean government-affiliated environmental technology institute supporting Korean environmental technology export and international cooperation programs. Plays an analogous role to OECC within Korea's environmental cooperation framework.

Broad incumbents

• UNDP (United Nations Development Programme): UN agency supporting developing countries on climate, environment, and sustainable development. Operates at larger scale across all sectors; OECC engages UNDP as coordinator of partner country transparency programs (e.g., cooperation via PaSTI and CDM-related activities).
• Japan International Cooperation Agency (JICA): Japanese government agency implementing bilateral ODA across all sectors including environmental projects that OECC supports as commissioned implementer. Broader mandate than OECC but closely overlapping operations, training programs, and partner country footprint.
• GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit): German federal agency implementing bilateral development cooperation programs including extensive climate, environment, and energy portfolios. Functions as the German counterpart to OECC, supporting technology transfer, capacity building, and project facilitation for partner country governments.
