Ambient particulate matter air pollution (PM) is one of the top ten causes of illness and death in the world. While PM pollution is worse in many developing countries, it remains a problem in the United States as well. Many people in the US may not be aware of the magnitude of the problem because the levels of pollution that present a health risk include concentrations that are usually not readily visible.

Report: When the Trump Administration Sidelines Science, Underserved Communities Face the Worst Consequences
October 30, 2019 8:49 AM EDT
As a public health researcher and a woman of color, I am acutely aware that in the United States some people live in communities which are afforded more science-based protections, allowing them to breath cleaner air, drink cleaner water, eat more nutritious food, and work at safer workplaces. And some people live in communities which are not afforded these protections. Read more >

Today marks the opening of a 45-day public comment period on a proposal (“Advanced Clean Trucks”) that would require truck manufacturers to sell electric vehicles in California. The proposal is modeled after the state’s policy requiring carmakers to sell electric vehicles in the state, a major reason California has a disproportionate number of the country’s electric passenger vehicles. The standard would apply to Class 2b-8 trucks, which range from large pickup trucks to delivery trucks and semi trucks.
Air Pollution from Cars, Trucks, and Buses in the US: Everyone is Exposed, But the Burdens are not Equally Shared

Air pollution has significant impacts to public health and the cars, trucks, and buses on America’s roads contribute to this problem. While we are all exposed to this pollution, there are significant differences in the average exposure to this air pollution by different racial groups in the U.S. and exposure also varies greatly depending on where in the U.S. you live.

California is a national leader in the transition to clean electricity, but integrating all that renewable energy onto the grid is no easy feat. Critics of renewables have long claimed that adding variable renewables (such as wind and solar) to the grid would force fossil-fueled power plants to operate less efficiently, leading to an increase in air pollution emissions. And as states start to integrate more renewables, those claims have come back.
But is this argument true? Do renewables really lead to increased air pollution?
