International Cooperation

EPA Collaboration with Japan

Acting Administrator Andrew Wheeler meets with Japan Environment Minister Masaharu Nakagawa at the G7 Environmental Ministers Meeting, September 18, 2018.

EPA has a long history of cooperation with Japan.  A government-wide agreement between the United States and Japan to cooperate on environmental protection has been in place since 1975. Through this agreement, the two governments exchange expertise; implement cooperative projects; and share information and data on research activities, policies, regulatory practices.

EPA and the Ministry of the Environment of Japan collaborate on decontamination and environmental management, mercury monitoring and implementation of the Minamata Convention on Mercury, and regional air quality.

Bilateral Meeting at G7 Environmental Ministers Meeting

On September 18, 2018, Acting Administrator Andrew Wheeler met with the Japan Minister of the Environment while attending the G7 Environmental Ministers Meeting in Halifax, Canada. The leaders discussed intent to develop a framework of measures to address marine litter in Southeast Asia, regional air quality including Japan having recently started contributing data to AirNow-International, the importance of continued cooperation on mercury and implementation of the Minamata Convention, partnering on environmental education through the Global Environmental Education Partnership (GEEP), and reducing carbon emissions. Themes for Japan’s hosting of a G20 Energy and Environment Ministerial meeting in Japan in 2019 were also discussed.

Japan Begins Sharing Data through Air-Now International 

The Ministry of the Environment began sharing Japanese air quality data within the AirNow-International system. The global AirNow-International community provides real-time air quality information to citizens, informing the public about the quality of the air they breathe.

Reduce Exposure to Toxic Chemicals: 

Decontamination and recovery: EPA co-chairs the Decommissioning and Environmental Management Working Group under the U.S.-Japan Bilateral Commission on Nuclear Decontamination.  This Commission was established after the Fukushima Daiichi nuclear disaster in 2011 to coordinate collaboration and assistance in recovering from nuclear incidents.  

Through this mechanism, the United States is both assisting Japan and increasing domestic security and preparedness. In recent years, EPA has shared technical expertise with Japan on lessons learned from environmental remediation, examining data analysis, effectiveness evaluation, technologies for volume reduction, and how to share results with the international community.  

Mercury management: Japan participates in the EPA-supported Asia Pacific Mercury Monitoring Network Exit to promote a network of monitoring and sharing data on mercury in the atmosphere in the Asia Pacific region. In September 2018, in conjunction with the 8th meeting of the Network, Japanese experts delivered an Atmospheric Mercury Sampling Workshop and donated six ambient monitoring toolkits to participating countries.

The U.S. and Japan play leadership roles in the UNEP Global Mercury Partnership. Through this, we are pursuing opportunities to collaborate with countries using mercury processes. Through a joint chlor-alkali mission to Uruguay in March 2018, officials discussed converting chlor-alkali and caustic soda production to use to non-mercury processes.

Promoting Environmental Education

EPA and the Ministry of the Environment of Japan promote quality environmental education and empowerment of youth through the Global Environmental Education Partnership and other bilateral and international platforms for sharing information and resources on environmental education.
