Utah Climate Week Win: Salt Lake City’s Comprehensive Sustainability Policy Now Includes All-Electric Provisions

What This Means and Why it is Important for our Air Quality and Climate

It’s the Sixth Annual Utah Climate Week and we’re bringing you news and tips from around Salt Lake City.

Today, we wanted to highlight an exciting update made in 2022 to Salt Lake City’s internal Comprehensive Sustainability Policy.

This policy was originally put in place in 2017 to cover a wide range of practices affecting Salt Lake City Corporation’s internal operations, standards, and protocols across seven different policies.

Each policy addresses the rules, regulations, and sustainable practices that must be considered and/or implemented while executing City operations that fall within one of the seven following categories: air quality and climate change, chemical reduction, materials management, petroleum storage tanks, property acquisition or sale, sustainable procurement, and water.

For example, the policy includes things as far-ranging as reducing paper waste and minimizing the use of plastic water bottles, to setting the standard when it comes to how we construct or remodel our municipal buildings.

We are practicing what we preach when it comes to sustainability!

The City’s Comprehensive Sustainability Policy was already significant in requiring that new construction or major renovation projects of City buildings over 10,000 square feet be evaluated for Net Zero Energy and be built to achieve at least LEED Gold. Salt Lake City’s Net Zero Public Safety Building and two Net Zero fire stations (FS 14 and FS 3) were constructed with these high environmental standards.

In 2022, at the urging of Mayor Mendenhall, we took the policy even further to require the evaluation of all-electric provisions for major new construction or renovation.

Getting to Know You: Ground Level Ozone

by SLCgreen intern Emalee Carroll

As Salt Lake City residents we are well acquainted with air pollution, but do we know what’s in it? With the Clear Air Challenge happening over the summer, we at SLCgreen wanted to take some time to provide a rundown on some of the different types of air pollution in Salt Lake City, what you can do about it, and what the city is currently working on and has done to make a difference!

What is Ground Ozone?

As we enter the thick of summer and all the fun outdoor activities that come with it, let’s break down a major summertime pollutant – ground level ozone. Ozone gas is naturally occurring in our atmosphere, helping to protect us from harmful UV radiation. However, ozone is not found naturally at ground level. Rather, the gas is known as a “secondary pollutant” meaning it’s created through a series of reactions between compounds in the air. This process is facilitated by heat and sunlight which is why ozone levels are typically higher in the summer months.

How does Ozone Affect SLC residents?

Like PM 2.5, studies have shown ozone also has adverse impacts on respiratory health. Ozone gas can reach deep into our lungs, damaging cells like a sunburn would, and trapping air in the alveoli. This process can cause coughing, throat irritation, chest pain, and congestion. Additionally, ozone can aggravate respiratory diseases such as asthma, COPD, and chronic bronchitis.

Aside from harming the health of Salt Lake residents, ozone can also negatively impact local ecology. When ground-level ozone enters the membranes of leaves, it reduces the ability of the plant to photosynthesize sunlight, slows growth, and ultimately weakens the organism. In extreme circumstances, this can lead to a loss of trees and other plants, which affects both the quality of life in urban settings, as well as the health of the overall ecosystem and animals that rely on those plants for food.

Getting to Know You: Particulate Matter 2.5

by SLCgreen intern Emalee Carroll

What is Particulate Matter?

One of the most common, and most dangerous, components of air pollution is particulate matter (PM).

Particulate matter can be composed of many different materials such as smoke, dust, soot, or even drops of liquid. Some particulate matter, like smoke, is large and dark enough that we can see it in the air, but others are so small we cannot see it with the naked eye. In an academic setting, particulate matter is often titled according to size and measured in micrometers. For example, a particulate matter that is 10 micrometers is referred to as PM10. Compare that to a very fine grain of sand which is roughly 90 micrometers.

The most common type of particulate matter in Utah’s air pollution is PM2.5. Particulate matter comes from primary and secondary sources.

A primary source of PM2.5 is anything that causes particle pollution directly, such as a wood stove, a forest fire, or a large dust storm or construction site on a windy day. Secondary sources are operations that emit gases which chemically create particulate matter. These are called “precursor emissions.” These can include operations like paint shops and dry cleaning operations. Some sources, like driving cars or power plants emit both direct and indirect PM2.5.

How does PM2.5 affect me?

Aside from making our beautiful valley difficult to see during an inversion, particulate matter also has negative impacts on human health. Because PM2.5 is so small, it can travel deep into our bodies, putting stress on our respiratory and cardiovascular systems. Those who struggle with asthma, chronic obstructive pulmonary disease (COPD), and other chronic respiratory issues can be adversely affected by the effects of PM2.5.

If you’ve ever experienced a flair-up of asthma symptoms during periods of high pollution, this is likely why. Even for individuals who are otherwise healthy, research from BYU found Utahns will have an average of 1.1 to 3.6 years taken off their lifespan due to heavy pollution. Yikes!

Mayor Mendenhall expands Air Quality Action Program for all City employees

PRESS RELEASE: June 30, 2022

As part of her commitment to improving air quality, Salt Lake City Mayor Erin Mendenhall has expanded a program urging eligible employees citywide to telework and take other actions to reduce air pollution on mandatory air quality action days, as forecast by the Utah Division of Air Quality (DAQ).

“Driving is still the number one source of pollution during both the summer and winter months when air quality is at its worst, so this is one of the most important behavioral changes we can make,” said Mayor Mendenhall. “I encourage other employers across the Wasatch Front to join us in implementing a similar program with their workforces and commend those who already do this.”

The Mayor launched the Air Quality Action Program this past winter to a smaller group of employees. With the initial pilot proving successful, beginning July 1, all City employees will now receive automatic emails when the Division of Air Quality forecasts a “mandatory action day,” meaning the concentration of air pollutants measured in Salt Lake County are predicted to reach or exceed levels of air pollution that are unhealthy for sensitive groups.

The City’s Sustainability Department designed the program notifications and communications, while the Information Management Services Department created a custom script and email that automatically pulls the forecast from DAQ’s website and notifies employees. The City’s program is similar to one the State of Utah also implements.

SLC Ranks 8th in EPA’s Top Mid-sized Cities for ENERGY STAR buildings

Salt Lake City is known for many things- hosting the 2002 Winter Olympics, being the subject of several TV shows and films over the years (including an episode in the newest Stranger Things season), and poor air quality to name a few. However, we can also add ranking 8^th in the EPA’s Top Mid-sized Cities with the most ENERGY STAR certified buildings in the previous year, to that list!

https://www.energystar.gov/buildings/about_us/newsroom/top_cities

What makes ENERGY STAR buildings so special? They’re more efficient than their peers!

Over 75% more efficient than similar buildings nationwide, in fact. Due to their efficiency, these buildings use an average of 35% less energy than typical buildings. Nearly 39,000 diverse buildings have earned the ENERGY STAR since 1999, ranging from the Empire State Building to an elementary school in the mountains of Alaska. Together, these buildings have saved more than $5 billion on energy bills and prevented nearly 22 million metric tons of greenhouse gas emissions—equal to the annual emissions of more than 2.7 million homes.

Salt Lake City boasts 26 ENERGY STAR certified buildings which prevented 31,500 metric tons of CO2 from being emitted last year! (That’s more than Utah’s other ENERGY STAR claim to fame, Provo, who placed second this year with 75 buildings. ;-p )

**Unico Properties** received the Salt Lake City Elevate Buildings Energy Management Award in 2019 in recognition for their work upgrading the HVAC and damper systems in the **250 Tower** following a Rocky Mountain Power wattsmart Business audit.

Connect SLC and Sustainability

Did you know that Salt Lake City is working on a new transportation master plan? Master plans are a great way to engage with your city and help make it a place YOU want to live in!

The last transportation master plan for Salt Lake City was published in 1996, over twenty years ago. In 2021, the Salt Lake City Transportation Division began Connect SLC, an extensive process to collect data, engage the public, and eventually create a new plan that better meets the needs of the city’s current residents.

Currently, the city is in Phase 2 of their civic engagement process and you can weigh in!

Phase 1 consisted of collecting values: air quality and the environment, reliability, safety, affordability, and equitable access to opportunity. With these values in mind, Phase 2 consists of expressing possible policy recommendations that the city could take and getting even more feedback from residents and user-groups!

What does this have to do with sustainability?

Everything! How we commute around the city has a major impact on the air we breathe, as well as other physical health concerns. Increasing access to safe routes for alternative transit increases the likelihood of people using it. This means fewer cars on the road, leading to lower emissions, and better air quality.

Additionally, improving accessibility to public transit makes choosing public transit more convenient, also increasing the likelihood of usage! This decreases the reliance on single-occupancy vehicles which in turn decreases emissions per person.

Data provided by the US Department of Transportation, Federal Highway Administration

The Salt Lake City Transportation Department has created an interactive website featuring policy recommendations for each value and an opportunities to provide feedback and comments.

Take this easy opportunity to provide feedback for your city!

It’s Bike Month!

At SLCgreen, we love biking for many reasons! Not only is choosing to commute with a bike better for human health, it’s also super beneficial to the environment (which also relates to our health).

This week, celebrate Bike Month by joining us on Mayor’s Bike to Work Day!

When: Wednesday, April 17th at 7:30am

Starts: Allen Park

Ends: City & County Building

Why do we love bikes?

Moving into the summer months it’s important to remember that air quality is still an issue. As we commute around the city, to work, festivals, and/or the farmer’s market, biking provides an environmentally friendly alternative to single occupancy vehicles. In the summer, pollution from cars, industry, and a multitude of chemical products, combined with high temperatures and bright sunshine, lead to harmful ozone levels.

Choosing to ride a bike is a great way to personally reduce your impact on climate change and help reduce air pollution!

The 2022 Lawnmower Exchange is Almost Here!

Salt Lake City residents can pre-register now to swap out their polluting lawnmowers for an electric upgrade

The State of Utah’s Lawnmower Exchange is back, and Salt Lake City will once again be participating!

In case you didn’t hear about last year’s lawnmower exchange, the program consists of residents exchanging their gas-powered mower for a (max: $299) coupon for an electric mower.

You might be wondering: Why lawnmowers? Lawnmowers are a significant source of air pollution. In terms of emissions, running a gas-powered lawn mower puts out the equivalent criteria pollution to driving a car 64 miles, according to the Division of Air Quality.

Switching to an electric mower is much cleaner. They’re easier to maintain and quieter to operate too!

Launching and funding this program every year is one of Mayor Mendenhall’s goals.

Last year, we provided funding for the exchange of 509 mowers, removing 4.02 tons of pollution from the airshed each and every year.

This year, our goal is to swap out 1,000 gas-guzzling mowers for clean electric options.

The 2022 Lawnmower Exchange

Switching to an electric lawn mower is a small way that you can make a big impact on our air quality.

Program highlights:

This year, the program is a coupon-based program ($299) for the online purchase of an electric mower of your choice through the vendors Home Depot or Redback.
FIRST, enter the lottery through our Salt Lake City resident pre-registration form NOW, or by signing up on the State’s website beginning at noon on April 4.
The State will notify you via email on Wednesday, April 6 if you have been randomly selected to participate.
SECOND: If you were selected, recycle your mower by taking it to a metal recycler OR by scheduling a pickup through Call 2 Haul.
After your mower has been recycled, you will receive a recycling verification number. Enter it on this site to unlock your coupon code.
THIRD: ORDER ONLINE: Once you select a vendor (Home Depot or Redback), you cannot change your mind and pick a different vendor! Input the coupon code at checkout.
You will have through April 17 to place your online order. Coupons will be invalid after that point.
$299 coupons will not work on an electric mower retailing less than $299.

For more information, visit slc.gov/sustainability/lawnmower/.

If you are not a Salt Lake City Resident, sign up at lawnmower.utah.gov on April 4th at 12pm.

Thank you for helping improve air quality!

Mayor Mendenhall Releases 2021 Report Card; Outlines Achievements and Priorities in her 2022 State of the City Address

Last week, Mayor Mendenhall released her 2021 Report Card, showing how the City fared on achieving the goals she laid out in January 2021.

We encourage you to check it out– particularly the “Air and Energy” page which details many of the projects we have worked on.

Then this week, Mayor Erin Mendenhall delivered her third State of the City address.

In addition to acknowledging the challenges of 2021 with the COVID-19 pandemic, homelessness, and affordable housing, the Mayor detailed significant progress on air quality and environmental initiatives.

She praised the determination residents and business owners have shown throughout the pandemic and other challenges the City has faced. “The City has shown tremendous resilience and grit; and incredible grace in trying to help others through this time,” she said.

With environmental achievements, the Mayor described historic progress:

From transitioning the City to net-100 renewable energy to expanding free public transit and planting trees, Salt Lake City is making significant efforts to improve the City’s air quality.

“These are the kind of steps I dreamed of as an air-quality advocate — our city is taking unprecedented control of its energy future,” Mayor Mendenhall said. “Every tree we plant, every mower we swap out, every public-transit ride, every energy-efficient upgrade and every net-zero building that goes up – combined with the 100 percent renewable energy that will soon flow into our city – we are making history together.”

That progress has come through four key approaches: removing pollution, investing in better data, reducing the volume of emissions created, and working to deliver 100 percent renewable energy to the entire city by 2030.

Here are a few highlights as they relate to sustainability from her speech:

Going All Outlet: How to Electrify Your Home

by SLCgreen Clean Energy Intern Monica O’Malley

As we celebrate the 5^th Annual Utah Climate Week, it is a great time to take stock of the ways we can act on climate at home. In our last post, we talked about the importance of energy efficiency. The cheapest and most “renewable” energy is the energy we don’t waste.

After you’ve made energy efficiency improvements to your home, it’s time to look at the type of fuel you’re using to power it!

Perhaps you have solar on your roof or a subscription to Blue Sky. Or maybe you’re supporting Salt Lake City’s efforts to move all of our community to net-100% renewable electricity!

As our electricity sources get cleaner, moving towards partially or fully electrifying your home is one of the many ways you can use to reduce your carbon footprint, as well as reduce local air pollution. When we advocate for building electrification, we mean switching to using all-electric appliances and heating/cooling systems in your home.

Building electrification can be accomplished at any stage — whether you are updating an old or broken appliance, renovating your space, building a new home, or just looking for ways to live more sustainably.

Benefitting the Environment

It may come as a surprise, but choosing energy efficient electric appliances and scaling-back the use of natural gas, heating oil and other fossil fuels will significantly reduce your household’s greenhouse gas emissions.

You might be thinking: But if my electric grid is powered primarily by fossil fuels, how will switching out my gas appliances for electric lower my carbon footprint? The short answer is energy efficiency and a grid transitioning to renewable sources.
