"... the number of environmental justice activists is growing and getting louder. Of course, this means some growing pains for the environmental movement at large. Most recently, a number of Californian environmental justice groups launched a campaign against carbon emissions cap-and-trade programs, over concerns that such programs would impact negatively the communities that are already disadvantaged. Many established environmental groups are not against cap-and-trade programs, as these carbon reduction programs are most politically feasible than carbon fees.
Still, the environmental movement's already showing a willingness to pay closer attention to environmental justice concerns. The Sierra Club, for example, released a statement concurring with some of what the environmental justice groups said: "We share many of the concerns of the EJ groups regarding pollution trading, like possible hot spots, loopholes and windfall profits."
Of course there are other points of view.
