Renewable Energy Institute operates Renewable Energy Users Network (RE-Users) since 2018 to promote and accelerate renewable energy procurement among corporations in Japan. Core members of the network are the corporate green team; people from environmental management and energy procurement departments. Members receive information on latest global and domestic renewable trends in the form of monthly newsletters. Information exchange meetings are regularly held allowing members to be connected and share best pracitices by leading corporations as well as being informed on new laws and regulations related to energy procurement.
A wide range of companies from different sectors have joined RE-Users and the Institute not only works together with these organizations to drive renewable deployment, but also identifies barriers and proposes solutions by communicating closely with energy users, NGOs and the government.
