The efforts of local governments are essential to achieving the Sustainable Development Goals (SDGs). To support these initiatives, an online platform providing SDG-related information was developed. The platform offers two main functions: searching for and sharing information. Users can search for plans, progress, and exemplary cases related to the SDGs across 1,788 local governments, while local governments can voluntarily share their own exemplary cases. Since its launch in 2018, the platform has been utilized by approximately 400 local governments, facilitating widespread information sharing.
