RE100 stands for 'Renewable Energy 100%' and is a voluntary campaign by multinational companies to produce 100% of electricity from renewable energy sources such as solar and wind power by 2050. This campaign was first presented in 2014 by The Climate Group, a global non-profit organization, and the Carbon Disclosure Project (CDP), a global environmental management certification agency. RE100 is not a mandatory agreement by governments or international organizations, but about 350 companies around the world voluntarily participate. As of 2022, four major Hyundai Motor Group companies, Hyundai Motor Company, Kia Motors, Hyundai Mobis, and Hyundai WIA, have joined the RE100 initiative. As a result, the four Hyundai Motor Group companies will promote a collaboration system to respond to RE100, direct renewable energy production, power transaction contracts, and green premium power purchases at the global business sites where they have jointly entered.
