We have study after study showing the harms of traffic related air pollution and its health and economic toll. We also have studies showing hope with sensible public policy and investments in clean air. I have covered some of that here at AirHealthOurHealth, for example my conversation with Professor Adar on diesel policy on school buses as well as the ROI of the Clean Air Act. What would happen if we really doubled down to move towards zero emission vehicles?
The American Lung Association has commissioned a study looking at just that called the “Road to Clean Air.” The analysis tries to answer the question, based on what we currently know of the health effects of PM2.5, ozone, NOx and more, including the upstream and downstream impacts from electricity source to tailpipe emissions, how much health and money would we save in the next few decades with a transition to electric vehicles? The study examines what would happen if new purchases of light and heavy duty vehicles in a spectrum of ten different categories were fully electric by either 2030 or 2050. Again, this is new purchases, not necessarily scrapping all the cars that are currently out there. AKA, what I might call a more realistic scenario. It also includes a more rapid transition for passenger vehicles, which already exist with very good technology, as well as a longer horizon for heavy duty trucks, which are more of a challenge.
I talk to Will Barrett on the podcast about how the study was done and its results. He has led the ALA’s work on clean air and climate change policy in California focusing on vehicle emission standards, smart growth and clean energy and fuels policies. He has also served as a public health representative on advisory panels, including the California Air Resources Board and the California Energy Commission. We discuss the two separate benefits of climate change mitigation and decreasing particulate matter, which the analysis breaks down.
People can look at the study results on the ALA’s website and also download particular analysis for their area of the country. Here is a breakdown for the Pacific NW from the public facing document, and links to the full technical report are in the references for today’s post.
I honestly think this is a conservative analysis because there are so many elements of the health costs of breathing particulate matter that we have yet to quantify. For example, in the current COVID19 pandemic, we are increasingly learning about the potential interaction of air pollution worsening transmission and severity of the virus. As someone in Oregon watching cases rise again around a month or so after our heavy smoke filled air, I think this is very plausible.
When your job is like mine, and every day you have to see people who are sick and dying from diseases caused or worsened by combustion of everything from tobacco to diesel, it is a real challenge to stay hopeful. It is particularly hard when there is a failure of collective action- nobody wants to take responsibility for the particulate matter they emit in their personal lives or their businesses. We think the costs should be borne by everyone else as a “cost of doing business.” And that is true to some extent- after all, we need food and medication delivered. But we should all have a say in how much pollution we are willing to tolerate and what we want our different tax dollars and incentives to fund. We also want to ensure we are incentivizing businesses and people that find ways to not pollute the air for profit or pleasure. For me, I want my community to invest in clean air so we save more lives and health. I see the faces of all my patients, and it is a strong motivator. Other countries, like Norway, have used incentives to have electric vehicles now comprise over 60% of their new cars sold, and electric vehicles are cheaper for working families over the long-term, another win-win for health and the economy. I hope this analysis helps people who have not met my patients, or have not (yet) met me as a lung doctor, understand another way that investing in clean air is a smart investment for our communities, our children, and our own wealth.
TLDR= Don't Light Things on Fire and Breathe them into your Lungs
What Can You Do?
1- Speak up about the health of clean air- you can sign the ALA’s petition to your local Governor to focus on healthy air here. Write a letter to the editor.
2- Ask your representatives at all levels of government, including your state legislature to incentivize electric vehicles. Ask your state, town or county to only purchase electric vehicles- frequently a municipality has bulk purchasing power and can invest in infrastructure that makes electrification more possible for individuals and businesses.
3- Donate to the ALA here- show support from the Air Health Our Health community!
4- Are you considering purchasing a new car soon? Choose electric! Or a plug-in hybrid with a decent range if you’re not ready to go full electric. Consumer Reports estimates a typical EV owner can save $800-$1000 on fuel costs especially if they charge at home, and lifetime savings of $4,600 on vehicle maintenance, oil changes, etc.
