This week, the largest-of-its kind study was published in JAMA and reveals that long term exposure to air pollution can have the same effect on human lungs as smoking a pack of cigarettes each day. The study was conducted between 2000–2018 and included 5780 participants in 6 US metropolitan regions followed up for a median of 10 years. The results were striking, as there is a statistically significant association between concentrations of air pollutants like ground-level ozone and black carbon and greater increases in emphysema.
The Study: As CNN explained, “The patients were all healthy when they started the study, and researchers controlled for factors that could compromise lung health, including age and whether the person was a smoker or was regularly exposed to secondhand smoke. The strongest association between a pollutant and emphysema was seen with exposure to ozone, which was the only pollutant associated with an additional decline in lung function.”
Troubling Sign: Ground-level ozone is particularly nasty and is on the rise. As EcoWatch reported, “While most air pollutants have declined thanks in large part to the Clean Air Act, ground-level ozone has actually increased. Ozone is colorless and forms when pollutants from fossil fuels interact with sunlight. Pollution from cars, power plants, refineries and chemical plants all contribute to smog, and it is on track to get worse.”
Why This Matters: Transitioning to a clean energy economy is about a lot more than just reducing greenhouse gas emissions, it’s a matter of public health. Air pollution from fossil fuels is shortening lifespans by causing chronic illness. So the next time you hear a lawmaker claim that it’s unrealistic to transition away from fossil fuels, just know that this isn’t a choice but rather an imperative to ensure that needless lives aren’t lost because we refused to act. This is a solvable problem, we just need the political will to do so.

By Ashira Morris, ODP Staff Writer Decreasing air pollution increases people’s life expectancy by an average of 2.2 years, according to a new study. Researchers from the University of Chicago found that by bringing pollution across the globe down to the World Health Organization’s guidelines, a collective 17 billion years could be added to the planet’s population’s […]
