This study by the University of California, Berkeley, commissioned by Pacific Environment, examines Japan’s innovative approach to decarbonizing maritime ports. “An analysis of Japan’s Carbon Neutral Port initiative and Yokohama Port and Harbor Decarbonization Plan,” takes an in-depth look at Japan’s Carbon Neutral Port (CNP) certification framework and the City of Yokohama’s port decarbonization initiatives. The CNP certification, established by Japan’s Ministry of Land, Infrastructure, Transport and Tourism in 2025, sets benchmarks for Japanese maritime terminals to reduce GHG emissions and improve air quality in port communities.
The study comes as momentum builds for decarbonization of the international shipping industry, despite recent delays at the International Maritime Organization (IMO). In a period of regulatory uncertainty and rapid technological change, the report underscores the importance of ensuring that certification systems and infrastructure plans continue to evolve in step with emerging fuel pathways, electrification needs, and international policy developments. It also offers recommendations to strengthen Japan’s port decarbonization efforts even further.
