Environmental policy of the United States As a result of the environmental movement in the United States, it continued to mature in the 1970s during which several environmental laws were passed, regulating air and water pollution and forming the Environmental Protection Agency (EPA). Partially due to the high costs associated with these regulations, there has been a backlash from business and politically conservative interests, limiting increases to environmental regulatory budgets and slowing efforts to protect the environment. Since the 1970s, despite frequent legislative gridlock, there have been significant achievements in environmental regulation, including increases in air and water quality and, to a lesser degree, control of hazardous waste. Due to increasing scientific consensus on global warming and political pressure from environmental groups, modifications to the United States energy policy and limits on greenhouse gas have been suggested.
Clean Air Act (United States) The 1970 law is sometimes called the "Muskie Act" because of the central role Maine Senator Edmund Muskie played in drafting the bill.[37]
