■ Background

Cities are responsible for approximately 70% of global greenhouse gas emissions and energy consumption. As such, in order to achieve the Paris Agreement’s 1.5-degree target, it is vital that cities accelerate the transition to a decarbonized society, and address various urban issues such as environmental pollution and circular economy in an integrated manner. MOE Japan has been implementing the "City-to-City Collaboration Program for Zero Carbon Society (C3P)," based on the belief that knowledge sharing and technical cooperation through city-to-city partnerships are effective measures to support such a transition. Since its establishment in FY2013, 67 cities and regions in 14 countries mainly in Asia and 25 municipalities in Japan have participated in this program.

This seminar will bring together C3P stakeholders and others from Japan and abroad who are working on local decarbonization, with an aim to further facilitate overseas expansion of excellent Japanese decarbonization and environmental technologies.
