In late March 2019, several corporate giants and their nonprofit partners launched the Renewable Energy Buyers Alliance. REBA is a trade organization that will help companies take advantage of new ways to purchase clean energy and new deal structures that allow them to directly support clean power projects. Corporate America has a major role to play, because commercial and industrial power users are the leading cause of energy-related greenhouse gas emissions in the US., said Miranda Ballentine, REBA's founding CEO. The organization's tech companies such as Google and Facebook are working with utility companies to meet corporate sustainability goals, while retailers such as Walmart and Johnson & Johnson are "now encouraging or requiring suppliers and vendor partners to come along on this clean energy journey with them," according to Rob Threlkeld, GM's global manager for renewable energy.
