Air Quality & COVID-19

In the months following our collective action to flatten the curve of COVID-19 cases, the air quality improved around the globe. According to University of Utah research, particulate matter pollution in Salt Lake City was reduced 59% as of May 6.

The collective social distancing practices resulted in reducing our community’s overall emissions – and cleaning up Utah’s notoriously bad air. But the lockdowns were an impermanent (and unfortunate) solution: as more cities reopen, emissions – and COVID-19 cases – are again on the rise.

Although Salt Lake City is maintaining an “orange” status for our COVID-19 response, there has been an uptick in cases across Utah. In a city in which public health is harmed by poor air quality, any virus that affects the respiratory system is cause for concern. However, with the knowledge that stay at home orders temporarily reduced our local air pollution, we can learn more about possible ways of improving air quality in the future.

Let’s take a closer look at the ways air quality and COVID-19 interact – and some ways you can help protect the air and each other.

Electric Vehicle Usage Increasing in Salt Lake City

Transportation accounts for nearly 50% of the pollutants that accumulate during inversions. Reducing emissions from cars is a great way to protect our air. Electrified transportation is a step towards cleaner air, healthier communities, and a stronger economy.

Graphic depicts air pollution statistics on orange clouds. Text reads: 
"Percent pollution reduced by an EV along the Wasatch Front. 57% PM10, 81% PM2.5, 98% SOx, 90% NOx, 99% CO, 99% VOC."
Electric Vehicles can significantly reduce air pollution.

EVs in Salt Lake City

Luckily, more and more Utahns are investing in electric vehicles (EV). Based on the number of unique charging sessions at Salt Lake City Corporation’s 36 Level 2 public EV stations (not including those at the Airport), there has been an exciting uptick in EV use in Salt Lake City.

In 2019, there were 21,371 unique charging sessions (meaning a car charged for longer than 5 minutes) at Salt Lake City public stations, compared to 12,870 in 2018.

Salt Lake City is following the national trend of growing EV use. According to the Edison Electric Institute, there are close to 1.5 million EVs being driven in the U.S. as of December 2019. Utah has seen its share grow to approximately 2% of total vehicles now comprised of electric, plug-in electric, or hybrid vehicles, and we want to continue pushing that number higher.

With EVs becoming more popular, Salt Lake City is working to strengthen the City’s EV infrastructure. In 2018, SLCgreen and Utah Clean Energy created the Electric Transportation Roadmap. Since then, Salt Lake City has installed 36 Level 2 charging stations at sites around the city, plus over a dozen at the Airport. These stations are free to use for 2 to 4 hours depending on the station.

Support Fellow EV Drivers: Don’t Hog the Charging Stations

Salt Lake City is pleased to see that charging sessions have increased significantly since the stations were initially installed. Up until now, Salt Lake City has not had to enforce the charging time limit. However, because more people are using the stations, drivers need to be mindful of their fellow EV users and respect the time limit.

In 2017, 1,500 sessions exceeded the time limit. That number has grown to 4,600 in 2019. While these only represent a small portion of the total charging sessions (80% of sessions were within the limit), it is still an inconvenience for other drivers who may need to fuel up.

Graphic shows graph of how many sessions exceed posted time limit.

Due to the growing demand for charging stations, the time limits will be actively enforced beginning March 9. Please be courteous to your fellow EV drivers and be mindful of the time limit. Drivers who exceed the posted time limit may be ticketed $75.

Vehicle charging usage may be monitored via the ChargePoint cloud system to determine if a vehicle has overstayed the posted parking time limit.

The public may also report potential EV stall overstays to the Compliance main line at 801-535-6628.

Clean Machines

Although electric cars still rely on electricity which is not (yet) wholly derived from renewable resources, they are still cleaner than gas-powered cars. According to the Union of Concerned Scientists, the average gasoline-only car produces 381 grams of CO2e per mile, while the plug-in hybrid produces only 191 grams and a battery EV produces only 123.

Graphic compares average CO2 emissions of gas-powered, plug-in hybrid, and battery electric vehicles. Stats are described in above paragraph.

Ride the Bus, Clear the Air, Take the Survey!

The Clear the Air Challenge is a little more than halfway over. This month, we’ve been inspired to see more of our friends and colleagues carpooling, walking, biking, and taking public transit to get around Salt Lake City.

Transportation emissions cause nearly 50% of the pollutants that become trapped in our airshed during inversions, so finding ways to get out of the car makes a difference!

That also why Salt Lake City continues to invest in programs that make using transit easier and more affordable for residents.

Have you heard of the Frequent Transit Network?

In 2018, the City passed a sales tax and bond initiative called Funding our Future, with the goal of increasing funding to support public safety, street repair, better transit service, and greater housing opportunities.

A robust transit system is the backbone of a thriving community. It also supports the city’s goal of curbing carbon emissions and clearing the air, so we are grateful that Salt Lake City voters supported it!

After significant public outreach, the first phase of the transit expansion began in August 2019.

Three east-west UTA bus routes were enhanced to provide more transit, for more people, with more convenience and reliability.

What does “Frequent Transit Network” mean?

Very simply, it means buses that run every 15 minutes during peak times, with early-morning, later-night, and Sunday service. That means you can rely on these lines to get you where you need to go, on your schedule.

Critically, these lines also offer key east-west connectivity, which is an enhancement to the Salt Lake City transportation network. These routes are the 2, 9, and 21 routes.

Join the Clear the Air Challenge 2020

Are you ready for a new challenge? How about one that will help you save money, burn calories, and improve our air quality? Salt Lake City employees are already on board and want to invite you to join the 2020 Clear the Air Challenge. During the month of February, keep our air clear of pollutants by limiting your driving!

You can aim to reduce your “driving-alone” trips every day in February, or pick a goal that’s manageable for you. It all helps!

If you don’t have a team and want to challenge yourself, please join the Clear the Air Challenge SLCgreen Team!

What is the Clear the Air Challenge?

Since 2009, Utahns have been participating in the month-long Clear the Air Challenge. During February, when air quality in Utah is historically bad, participants track their trips with the goal of avoiding single-occupancy vehicle travel and reducing air pollution. Participants carpool, bike, walk, telecommute, trip chain, take public transit, drive electric vehicles, and ride electric bikes or scooters– all to help clear the air!

In 2019, participants in the Clear the Air Challenge eliminated 84,421 single-occupancy vehicle trips. This saved 1,244,624 miles of traveling and $0.4 Million! Together, all these efforts reduced 359.8 tons of CO2!

This year, the Clear the Air Challenge needs everyone’s help to reach the goal of eliminating 100,000 single-occupant trips.  

Clear the Air to Protect Our Health

Winters in Utah can be beautiful, but when inversion starts, polluted air gets caught in our valleys. PM 2.5 and other pollutants threaten our health the well-being of our communities.

On bad air days, our activity is limited. Moreover, children, older adults, and people with heart diseases or respiratory problems are at a higher risk for suffering from poorer health due to bad air. Poor air quality is associated with a range of negative impacts including pregnancy losspremature deathchild asthma, and increased cases of pneumonia.

In Salt Lake City, nearly 50% of air pollution comes from cars, trucks, and other vehicles. That’s why the Clear the Air Challenge is more important than ever.

We love it when the air is clear!

What We’re Doing

Salt Lake City Corporation employees are already signing up to do their part to Clear the Air this year (see our previous Challenge roundup).

Each participating department has its own team. Salt Lake City employees live all over the Wasatch Front. Many of us take public transit to work every day. Others carpool or bike. For the month of February, we’re doing all we can to cut back on our single occupancy car rides!

Salt Lake City departments compete with each other for the coveted Clear the Air Challenge “Mayor’s Cup” and “SLCgreen Team Spirit” award.
.

Thanks to the recent public transit expansions, the robust network of bike paths for the sunny days, as well as the Clear the Air Challenge app’s handy carpool guide, the Clear the Air Challenge will make February an exciting and competitive month!

We've Got the December Bad Air Blues

The view from the SLCgreen office on Dec. 4, 2019.

With a week of air that has been some of the worst in the country, it’s no wonder we’re all feeling frustrated. Salt Lake City’s current air quality is unhealthy for sensitive groups and requires mandatory action of limited driving and no wood burning. For most of us, Salt Lake City’s notoriously bad air is a nuisance and health concern, limiting our activities and turning our skyline grey. Moreover, pollutants like PM 2.5 are dangerous, especially for older residents, children, pregnant women, and people with respiratory and cardiovascular conditions. Air quality is a public health concern, as well as an economic one.

It may come as a surprise that although transportation currently contributes nearly half of the emissions causing Salt Lake City’s bad air, buildings are catching up. Indeed, houses and buildings currently contribute roughly 38% of emissions, and industry point sources produce the other 13%. As emissions standards on cars are becoming more strict, managing emissions from houses and buildings is a growing priority.

PM 2.5 is the primary winter concern in Salt Lake City’s airshed. The particulate matter poses serious health risks and gets trapped in the Salt Lake valley during inversion. Most of the PM 2.5 is a direct result of precursor emissions from tailpipes, smokestacks, and chemicals that mix to form PM 2.5 in the atmosphere.

When you look outside, it may feel like there’s no good news. However, per capita pollution in Utah is decreasing. Salt Lake City is taking steps to help clean the air and protect our public health and environment. Find out how you can keep our airshed (and lungs!) clean and healthy.

What is SLC doing?

Reducing combustion and emissions are a key step towards cleaning the air.

Salt Lake City has many air quality initiatives in place that are helping clean the air. Among these include the continued expansion of EV infrastructure, expanding cleaner vehicles in our fleet, and implementing our energy benchmarking ordinance for nearly 1,000 commercial buildings. Additionally, the HIVE pass provides residents with access to UTA’s public transit system at a reduced cost.

Salt Lake City built the nation’s first Net Zero energy Public Safety Building.
In 2018, Salt Lake City converted five parking enforcement vehicles to all-electric Chevy Bolts. As of Oct. 2019, the Salt Lake City fleet has over 135 hybrids, 32 all-electric vehicles, 72 compressed natural gas heavy duty vehicles, and 117 clean diesel heavy duty vehicles.

Clearing the air is easier than ever

Winter is coming. And along with it, inversion season. As temperature and pressure changes trap pollutants in the Salt Lake Valley, it is an important time to recommit to reducing our impact.

Air pollution in general is extremely costly in terms of public health and our economy. In the U.S., we spend $131 billion in air quality-related damages each year. The costs to our well-being are enormous. Bad air is linked to asthma, pneumonia, pregnancy loss, and premature death.

Luckily, expansions to our public transportation infrastructure are making it even easier to leave your car at home and help clear the air.

Public Transit Expansions

One way to avoid driving is to make use of public transit.

In July, Salt Lake City and the Utah Transit Authority expanded services on three essential routes, the 2, 9, and 21 bus. The expansions are critical steps towards improving air quality because they allow more riders to take advantage of the public system.

The bus route expansions are among several enhancements made possible through the Funding our Futures income (comprised of a sales tax increase, passed by the City Council, and a bond, approved by Salt Lake City voters, in 2018.)

The results are already starting to come in!

Check out our new electric vehicle page

We’re excited to announce a new electric vehicle page on slc.gov!

Electric vehicles can improve our health and our economy. That’s why electrification of our transportation system is an important focus of SLCgreen’s activities. EVs are one of the most important tools for cleaning our air, improving the health of our citizens, strengthening our economy, and reducing our carbon footprint.

Market projections show that electric vehicles sales are increasing, and will soon take over as the standard form of single-passenger travel in the U.S.

In Salt Lake City, we hope to be ahead of the curve for electric vehicle adoption, as we know how much it benefits the health of our citizens and strengthens our economy.

With support from the City Council and Mayor Biskupski, we have installed a number of SLC Corporation owned and operated charging stations throughout the city. We are also committed to cleaning up our energy grid, making EVs an even cleaner option!

We are working hard to provide comprehensive and accessible information for SLC residents on electric transportation. You may have heard our interns talking about EVs at community events, and we write about EVs on our blog a lot! However, we felt it was time to provide a one-stop-shop for EV information.

Enter slcgreen.com/ev.

Check out www.slcgreen.com/ev to see all the great information we put together on electric vehicles.

On this page, you will find our Electric Transportation Roadmap, how EVs help the environment, charging information, links to our partner organizations, and more.  We hope all our readers will understand why swift EV adoption is an important part of our initiatives after visiting our webpage.

Please don’t hesitate to reach out to our office with questions, concerns, or comments about electrified transportation in Salt Lake City. You can find us at slcgreen@slcgov.com.

EVs are a key part of our commitment to a healthier, cleaner, and more equitable city.

Paying for Poor Air: The Cost of Regional Air Pollution

By SLCgreen intern Kelbe Goupil

Air quality, air quality, air quality…will we ever stop talking about it? Until our air is consistently clean and no longer putting our health and economy at risk, probably not.

Bad air day in Salt Lake City

Talking about air pollution is important to us here at SLCgreen, not only because of how harmful it is to our health but also because of how expensive it is.

Let’s face it: bad air is damaging our economy. And not just in Utah. Air pollution in the U.S. costs the nation at least $131 billion in damages annually, including higher healthcare costs. Globally, the cost of pollution-related death, sickness, and welfare is $4.6 trillion per year, which is about 6.2% of the global economy.

Let’s talk about why that is and what can be done about it.

World Environment Day: What We Can Do to Combat Indoor and Outdoor Air Pollution

by SLCgreen intern Linda Derhak

World Environment Day 2019

Since 1974, June 5th has been a day for global action to protect the environment. Celebrated in over 100 countries, the UN’s World Environment Day raises awareness on urgent issues such as plastic pollution, sustainable consumption, wildlife crime, and climate change. The day empowers people around the world to create change as individuals and communities. This year’s host country, China, is bringing attention to a pressing global crisis: air pollution.

Global air pollution is worsening. According to the UN, 9 out of 10 people breathe in polluted air and it causes 7 million premature deaths a year. China is leading a charge against air pollution, and countries world-wide are helping make sure people have access to clean air.

Here in Utah, we have our own struggles with air quality — mainly with seasonal issues such as PM2.5 pollution in the winter and ozone pollution in the summer. Across the Beehive State, air pollution leads to increased illness. Salt Lake City and other communities statewide are working to improve air quality and the State’s Department of Air Quality has led many efforts over the years to reduce pollution.

But more is needed.

In honor of #WorldEnviornmentDay and the goal to #BeatAirPollution, here are some easy ways we can all be part of the effort to improve indoor and outdoor air quality.
