AFL-CIO, along with other labor groups are opposed to the New Green Deal proposed by Senator Ed Markey and Representative Alexandra Ocasio Cortez. In their letter to Markey and AOC, the union agrees that there needs to be change in order to address climate change, but the Green New Deal lacks specific solutions that address the job security of union members. They strongly feel that the reforms can cause “immediate harm,” and will not accept the proposal. Despite their sentiments on the issue, they are willing to discuss the issue in depth and seek a compromisable solution.
