Environmentalists have been pushing for expansion of the National Environmental Policy Act (NEPA) and it appears they may finally be getting their wish. It appears that the Obama Administration may issue an executive order that would add climate change as one of the factors that federal agencies must consider when reviewing projects and policies under NEPA. Adding climate change to NEPA could make it more difficult for some policies and projects to move forward. Businesses have spoken out against incorporating climate change considerations in NEPA analyses, arguing that it could slow down the process and hurt the economy. Environmental groups think differently. Sierra Club chief climate counsel David Bookbinder said, "People will think longer and harder and smarter about what they build when they understand that the environment around them is changing."
