History

Historical Context

The Clean Air Act Amendments of 1990 aimed to reduce air pollution by enforcing stricter regulations, including a cap-and-trade system for sulfur dioxide emissions. Despite these efforts, compliance monitoring remains challenging, as evidenced by Marathon Petroleum's $46 million in tax exemptions. This situation reflects ongoing debates about the effectiveness of financial incentives for pollution control and their implications for environmental policy and accountability.
