In April of 2024, Incheon Metropolitan City established a comprehensive plan to attain carbon neutrality by 2045. The City plans to phase out coal-fired power plants, which account for 49% of total GHG emissions, by 2044. To fill the gap, Incheon has strengthened energy transition strategies, focusing on new renewable energies such as solar and wind power and hydrogen energy. It has been pursuing decarbonization in the areas of transportation, building and industry. Additionally, hydrogen-based infrastructure has been built to reduce carbon emissions. Furthermore, nature-based carbon absorption strategies are implemented, including expansion of urban green spaces and marine halophyte habitats.
