Seminar on City-to-City Collaboration for Zero Carbon Society 2026

Cities are responsible for approximately 70% of global greenhouse gas emissions and energy consumption. As such, in order to achieve the Paris Agreement 1.5-degree target, it is vital that cities accelerate the transition to a decarbonised society, and address urban issues in an integrated manner. IGES, together with MOEJ, has been implementing the "City-to-City Collaboration Program for Zero Carbon Society (C3P)" since 2013, based on the belief that knowledge sharing and technical cooperation through city-to-city partnerships are effective measures to support such transition.

This seminar brought together international stakeholders, including C3P stakeholders and others who are working on local decarbonisation. The discussions aimed to build momentum for local decarbonisation and inspire a decarbonisation domino effect both domestically and internationally. Additionally, advanced examples of collaborative projects designed to create synergies with regional revitalisation initiatives in the host prefecture of Ehime were also presented.

In addition to this public seminar, private peer learning sessions on regional decarbonisation and on-site visits to decarbonisation initiatives were organised for 2025 C3P members.
