Passing up on a clean- air hero

Re “Progressive activists block Nichols’ path to EPA,” Dec. 18

While we support environmental justice goals, as air pollution researchers with a century of experience between us, we are dismayed at the singleissue attacks on Mary Nichols’ distinguished record that prevented her selection as head of the U. S. Environmental Protection Agency.

Under her leadership as chair of the state’s Air Resources Board, California is the global leader in effective air pollution and climate change policies. Smog has decreased dramatically under Nichols’ leadership, resulting in countless lives saved and improved health, with special benefits to socioeconomically disadvantaged populations and communities of color in inland areas.

The Trump administration tried to thwart vehicle mileage standards to reduce carbon dioxide emissions implemented on Nichols’ watch. In response, she negotiated with automobile manufacturers to support the standards, providing to many people climate, air quality and health benefits.

We could cite numerous other policy and technology advancements overseen by Nichols, policies that have been emulated both nationally and internationally. All of us owe her a great debt of gratitude for her impactful and unprecedented achievements over five decades of public service.
