The removal of lead from gasoline resulted in a significant reduction in emissions of lead into the environment, and the estimate of a 94% reduction is widely supported by scientific research and data. The use of leaded gasoline was a major source of atmospheric lead pollution, which posed serious health risks, particularly to children, including developmental issues and neurotoxicity.

After the transition to unleaded gasoline, emissions of lead dropped substantially, leading to improved air quality and public health outcomes. The majority of the decline can be attributed to the decreased use of leaded gasoline, which was phased out primarily during the 1980s and early 1990s as part of a concerted effort to mitigate health risks associated with lead exposure. This removal ultimately led to cleaner air and significant public health benefits, highlighting the efficacy of regulatory measures aimed at reducing harmful emissions.
