Quizplus · Accepted Answer

The EPA (Environmental Protection Agency) has had significant impact through regulations and enforcement of laws related to reducing emissions of greenhouse gases in the United States. The Clean Air Act, for example, has led to regulations on emissions from vehicles and power plants, which has contributed to reducing greenhouse gas emissions. The Kyoto Protocol and Copenhagen Accord are international agreements aimed at reducing global emissions and have had limited impact on the United States, as the country has not ratified the former and withdrew from the latter. The Superfund program, while important for addressing environmental cleanups, does not directly address greenhouse gas emissions.
