For the last 20 years, unions in the U.S. and internationally have generally accepted the dominant discourse on climate policy, one that is grounded in assumptions that private markets will lead the “green transition,” reduce emissions, and stabilize the climate over the longer term. Indeed, unions began attending the climate negotiations convened by the UN in the early 1990s, a time when the “triumph of the market” went unchallenged and the climate debate was awash with neoliberal ideas. Unions therefore focused on articulating the need for “Just Transition” policies.
