Particulate Matter in a Changing World: Grants to Combat the Impacts of Climate Change

By Christina Burchette

There are certain things that are always changing: the weather, fashion trends, and technology (which iPhone are we on again?) are a few that come to mind. I can always count on the fact that these things won’t stay the same for long. But there are other things that I typically expect to remain the same: I expect to get hungry around lunchtime, I expect the bus to come every morning, and I expect to be able to breathe clean air. I don’t even think about the possibility of these things not happening—until something changes.

I definitely don’t think about air quality often or expect it to change. As long as I’m breathing and well, why would I? But in reality, air quality changes every day, and over time it may change a lot depending on how we treat our environment—and we need to be ready for these changes. This is why EPA recently awarded research grants to 12 universities to protect air quality from current and future challenges associated with climate change impacts.

Climate change is affecting air quality by influencing the type and amount of pollutants in the air. One type of pollutant present in our air is particulate matter, or PM. Long-term exposure to PM is linked to various health effects, including heart disease and lung function, and it doesn’t take a high concentration to affect our bodies. The more PM there is in the air, the more likely we are to be affected by health conditions.

With EPA Science to Achieve Results (STAR) grants, university researchers are approaching the future of air quality from multiple angles with a focus on learning more about the PM-climate change relationship. They will study the impacts of increased wildfire activity that generates PM, often called soot, in the Rocky Mountains. They will look at the impacts that climate change and land use change have on the development of dust storms in the West and Southwest; and they will evaluate the best means of energy production in California where air quality is among the worst in the nation to reduce health care costs and lower levels of PM and greenhouse gases.

Over the next few decades, climate change will be the catalyst for various environmental trends, so finding a way to manage the impacts of these trends is essential to protecting our health. The work these grantees do will help to inform air quality managers and others to make sustainable and cost-effective decisions that keep our air quality at healthy levels and protect public health and the environment. That way, future generations will think of good air quality as something we can expect.

Air Quality Awareness: A New Generation of Research

By Dan Costa, Sc.D.

Graphic of clouds and buildings in a silhouette cityscape. It’s Air Quality Awareness Week! This week, EPA is showing how we care about the air by announcing grants to three institutions to create air research centers. We now understand more than ever about the threats of air pollution to environmental and human health, but there is still more to learn. EPA has a history of supporting research and development that complements the work of our own staff scientists to bolster scientific knowledge about the effects of air pollution. EPA uses this knowledge to address many pressing questions and understand connections between our changing environment and human health.

Since 1999, EPA has funded three rounds of research centers through a competitive grant process. The scientific experts at these centers have contributed to a more complete understanding of the persistent air quality challenges that continue to face our nation. The first round of EPA funded air research centers focused on particulate matter and examined the link between particulate matter and cardiovascular disease. In 2005, the next round of centers focused on whether differing health effects could be linked to specific sources of air pollution. By 2010, it was clear that to get an accurate understanding of real life exposures, we needed to examine the health effects of exposure to multiple pollutants at once instead of just one or two at a time. The third round of centers took on this complex challenge. The next step is to delve into questions regarding how the health effects of air pollution may vary in different cities and regions across our country – each with its own unique characteristics and set of pollution sources.

This leads us to today and our exciting announcement–EPA is awarding $30 million through its Science to Achieve Results (STAR) program to fund the establishment of Air, Climate, and Energy (ACE) Research Centers at Yale University, Harvard University and Carnegie Mellon University. These Centers will consider changing energy production methods and local climate, while investigating the effects of global climate change, technology, and societal choices on local air quality and health.

I am eagerly anticipating the many new tools and ideas that will be produced by this next generation of EPA funded air research centers.

EPA “Aim High” Success Stories on Climate and Air Quality

By Administrator Gina McCarthy

The public health case for climate action is compelling beyond words. The interagency Climate and Health Assessment released last month confirms that climate change endangers our health by affecting our food and water sources, the weather we experience, and the air we breathe. And we know that it will exacerbate certain health threats that already exist – while also creating new ones.

As we celebrate the recent signing of the historic Paris Agreement by countries around the world, there’s no better time to reflect on EPA’s many ongoing efforts to fight climate change and protect the air we breathe.

As part of our “Aim High” effort to highlight success stories from across the agency, I asked EPA staff to share examples of their work to protect public health by taking action on climate and air quality. Here are some highlights:

Child with pinwheel and blue sky in the background.Asthma Awareness Month: Asthma affects nearly 23 million Americans and disproportionally impacts low-income and minority communities. In the U.S., the direct medical costs of asthma and indirect costs, such as missed school and work days, amount to over $50 billion a year. Every May, EPA leads a National Asthma Awareness Campaign to increase public awareness about asthma risks, strengthen partnerships with community-based asthma organizations, and recognize exceptional asthma programs that are making a difference. Every year, this effort reaches 9,000 groups and individuals and provides them with the information and motivation to take action.

Group photo of employees from EPA and the Ghana Environmental Protection Agency .U.S EPA Africa Megacity Partnership: EPA’s environmental program in sub-Saharan Africa is focused on addressing the region’s growing urban and industrial pollution issues, including air quality and indoor air from cookstoves. The World Health Organization estimates that exposure to smoke from cooking causes 4.3 million premature deaths per year. EPA and the Ghana Environmental Protection Agency are working together under the Africa Megacities Partnership to develop an integrated air quality action plan for Accra. As a result of this partnership, Ghana EPA has already made significant progress using air quality monitoring and analysis and is serving as a model for other African cities with limited data, that want to take action.

Group of people by reservoir impacted by drought.Climate Change and Water Utilities: Between 1980 and 2015, the United States was impacted by more than 20 major droughts, each costing over one billion dollars. EPA staff in the Office of Water developed an easy-to-use guide to assist small- to medium-sized water utilities with responding to drought. The Drought Response and Recovery Guide for Water Utilities, release last month, includes best practices, implementation examples and customizable worksheets that help states and communities set short-term/emergency action plans, while also building long-term resilience to drought. EPA staff also developed an interactive drought case study map that tells the story of how seven diverse small- to medium-sized utilities in California, Texas, Georgia, New Mexico, Kansas, and Oklahoma were challenged by drought impacts and were able to successfully respond to and recover from drought.

Screenshot of EPA Region 1 Valley Indication Tool.Outreach on Risks from Wood Smoke: Exposure to particle pollution from wood smoke has been linked to a number of adverse health effects. Valleys in New England, where terrain and meteorology contribute to poor dispersion of pollutants, are especially vulnerable during winter air inversions. EPA Region 1 used publically available study results, databases and in-house Geographic Information System resources to develop “The Valley Identification Tool” that identifies populated valleys throughout New England that are at risk for wood-smoke pollution. Using this tool, EPA and state air quality managers and staff can better plan air-quality monitoring, outreach, and mitigation.

Biogas facilityBiogas to Energy: Water Resource Recovery Facilities (WRRFs) help recover water, nutrients, and energy from wastewater. EPA Region 9 is working with WRRFs to boost energy production through the addition of non-traditional organic wastes ranging from municipally collected food scraps to the byproducts of food processing facilities and agricultural production. As a result of these efforts, some of these facilities are becoming “energy positive,” producing enough energy to power the facility and transferring excess energy into the electricity grid for use by others. EPA, in collaboration with universities and industry, is also working to collect and share information on co-digestion practices and biogas management technologies. This work helps improve understanding of the air quality impacts of biogas-to-energy technologies and helps state and local governments, regulators, and developers identify cleaner, geographically-appropriate and cost-effective biogas management options.

This Spring, Show How You Care About the Air

By Jenny Noonan

What do our kids need to know about air quality? How can we teach them about the links between health and air pollution?  With a pre-kindergartener and a 3rd grader at home, my husband and I are always looking for ways to engage them about the fragility and resilience of the natural world. My job at EPA helps me do that and Asthma Awareness Month and Air Quality Awareness Week (May 2-6, 2016) give me a focus each spring.

This year’s Air Quality Awareness Week theme, Show How You Care About the Air, is a great opportunity to take to social media to share the importance of clean air to my family and yours.

For 10 years, we have sought out state and local partnerships to raise awareness about the connections between air quality and health. We’re highlighting events sponsored by our partners on our website. Show How You Care About the Air is a coordinated theme with a special focus each day of the week, including:

Monday, May 2                 Highlighting State and Local Events

Tuesday, May 3                 Asthma and Air Quality (World Asthma Day)

Wednesday, May 4            Air Quality Around the World

Thursday, May 5               Air Quality Trends

Friday, May 6                    Citizen Science

As part of Asthma Awareness Month, we will be sponsoring two Twitter chats to increase awareness. The first will discuss topics such as the environmental triggers of asthma – both indoors and out – and how you can develop a personal asthma plan to help manage these triggers. You can follow along or participate in this chat, co-sponsored with the Centers for Disease Control and Prevention (CDC) on May 3, from 2-3 pm by following #AsthmaChat, or leave a question below.

We will also be hosting a Twitter chat with CDC on air quality issues on May 5, from 1-2 pm. This chat will talk about topics like the impacts of air pollution on human health, and how you can use air quality tools to reduce your exposure to pollution. Join the conversation at #AirQualityChat, or leave a question below.

Finally, everyone has an opportunity to take a selfie or other photo showing how you care about the air during Air Quality Awareness Week 2016 and share it on the AirNow Facebook page.

Cockroaches in the School Kitchen

By Marcia Anderson

Cockroaches can be major pests in restaurants, hospitals, warehouses, offices and buildings with food-handling areas. Cockroaches are known to carry human pathogens, such as Salmonella and E. coli, which can result in human diseases, such as food poisoning or diarrhea.cockroaches on the floor

This message came from the state of Maine’s Department of Agriculture, Conservation and Forestry. Really, it could come from nearly any state, any country or any continent. Cockroaches are one of the most common animals on earth.

Late last summer, I visited a school in the Northeast that was overrun with cockroaches. A custodian led us to classrooms, restrooms, storage areas and, finally, the cafeteria and kitchen. Most of it was cleaned during summer break. But when we entered the cafeteria, we found the floor littered with debris – food wrappers, papers, plastic drink bottles, and food.

We flicked on the lights and the floor moved. Thousands of cockroaches were scurrying from the light. We did a dance to avoid the mass of moving bodies.

Custodians had been directed to clean the building from the top down and the kitchen and cafeteria were on the ground floor. They were told not to clean the kitchen – that was up to kitchen staff. As the end of the year approaches, this results could be instructive for this year’s summer cleaners.

The kitchen staff had only a few days at the end of the school year to clean. Countertops, stovetops and sinks appeared clean, but ovens were caked with grease, as were pipes coming from the stoves, and floors under appliances.

Amer Cockroach  Clemson Univ  USDA Coop ex  Bugwood  1233111Large indoor cockroach populations are a leading cause of allergies, asthma and other bronchial disorders. In fact, cockroaches are one of the main triggers for asthma attacks for children in inner cities..

The presence of cockroaches is an indication that food, moisture and save havens for the roaches are present. Conditions in this school kitchen allowed the cockroach population to explode.

We advised the school to reduce the cockroach infestation by incorporating Integrated Pest Management practices. EPA recommends all schools manage pests using this approach.

Cockroach control is best accomplished through prevention, exclusion, sanitation and monitoring. Not only would these measures help prevent an infestation, they would reduce cockroach-related allergens.

Because of the severity of the infestation, we recommended the school get professional advice and service.

Here are some IPM-based actions your school can take to help reduce and prevent cockroaches and other pests. These tips can also work in your home if you have a problem with unwanted insects.

Sanitation. Eliminate sources of food and moisture, as well as hiding places for pests. Every day, sweep and mop areas that could attract cockroaches. Empty trash containers frequently, and line them with plastic bags. Kitchen appliances and areas around appliances should also be kept clean.

Exclusion. Cockroaches easily move through plumbing and electrical connections. Gaps around plumbing, electrical outlets, and switch plates should be sealed. Kitchen staff should scan grocery items for evidence of cockroaches before putting items away. Remove cardboard as cockroaches love to dine on the glue that holds boxes together.

Eliminate Water Sources. The single most important factor in determining cockroach survival is the availability of water. German cockroaches live less than two weeks without water.

Eliminate Harborage. By nature, cockroaches prefer dark, warm cracks and crevices. Any small gap or hole (1/16” or larger) that leads to a void is a prime cockroach living area. These cracks and crevices should be sealed.

Following these simple steps in your school will result in fewer pest problems.

EPA offers information about cockroaches and asthma along with a Citizen’s Guide to Pest Control and Pesticide Safety. We also recommend exploring the EPA-sponsored Asthma Community Network website and visiting our school IPM website.

Driving to show we care

By Gina Snyder

Last summer, I had the opportunity to drive an extended range electric car. This is a vehicle that drives only on the battery until all the charge has been used up, then it uses a gasoline engine and hybrid technology for excellent mileage. But the really interesting thing about this car was the extensive feedback on my driving “performance.”

ElectricCar P1040099

A spinning green globe on the dashboard let me know when I began to accelerate out of the efficient range. Not only that, but on this 90-degree day, when I used air conditioning, the climate conditioning display also showed how much power was going to keep the cabin space cool. It turned out that using the eco-air conditioning used 21 percent of the engine’s power on cooling the cabin, but pushing the ‘comfort’ button drove it all the way up to 35 percent of the engine’s power! That just goes to show how much energy it takes to run air conditioning.

I don’t continuously focus on doing everything possible to conserve fuel when I drive, but I do like to drive with fuel efficiency in mind. The best tip I’ve ever found was to drive a car like you would ride a bike. It helps if you think about spending energy as wisely in your car as you do when you ride.

Here are some examples:

  • Ensure your tires are properly inflated and vehicle is in good mechanical condition – this reduces rolling and mechanical resistance. Proper tire pressure is safer, extends tire life, and can provide up to 3 percent benefit per tankful of fuel.
  • Smart braking means that you coast to stops. Go easy on the gas pedal just like you don’t pedal madly towards stop signs and then jam on the binders on your bike.
  • “Driving with load” on hills saves energy. You don’t usually power up hills trying to maintain your previous cruising speed on your bike, do you?
  • Reduce speed. It’s easier for cyclists, who are highly attuned to the relationship between aerodynamic drag and the energy consumed to travel at high speed.
  • Don’t idle your car unnecessarily. You don’t sit and spin your bike pedals while waiting for someone, nor do you ‘warm up your bike’ in the driveway, do you?

Being attuned to your performance as an efficiency-conscious driver will result in a style that mirrors the smooth and steady progress you make on a bicycle. We can all be smooth operators this summer. Go easy on the brake and gas pedals when you approach traffic lights and stop signs. Stopping and accelerating gradually not only gives you a smoother ride, it saves gas—and that’s good for the air and good for you!

Olive Oil and Fish Oil: Possible Protectors against Air Pollution

By Rose Keane

My grandmother is 97, and last year she chopped down an orange tree in her backyard with an axe. Recently I asked her how she was still able to live and move around so independently, and she says to me in her thick Austrian accent, “I take fish oil tablets – they’re very good.” Many people have said that fish oil will improve your health, but when you ask them they have no idea how or why. EPA scientist Dr. Samantha J. Snow is working to answer some questions about what fish oil may do by investigating the potential link between fish oil and how the body handles air pollution exposure.

Dr. Snow looks at a slide

EPA scientist Dr. Samantha J. Snow

Snow is receiving the Women in Toxicology’s Postdoctoral Achievement Award, presented by the Society of Toxicology (SOT), at the annual meeting held in New Orleans this week. Her recent research uses animal models to look at how these oils in the diet might change how the body handles exposure to ozone, a common outdoor air pollutant. A large body of scientific research has shown that the lungs and heart can be affected by air pollution. Scientists like Snow are studying whether ozone pollutants in the air are damaging other organ systems and even how our bodies use and regulate energy, also known as our metabolism. Snow and her colleagues are trying to find out whether adding fish oil to a diet can help people like my grandmother ward off the damaging effects of air pollution.

What the team discovered so far is that fish oil and olive oil could potentially protect muscles in the body from breaking down due to air pollution exposure. That might explain how my Oma was able to tackle that tree! The preliminary findings also suggest that fish oil could protect against higher levels of cholesterol caused by air pollution. However, olive oil was linked to a decreased ability to regulate glucose levels in the blood after ozone exposure.

Dr. Snow using a microscopeThese results could have very interesting implications for health research in the future, and could help scientists better identify how changing our diets might actually help protect our bodies from the harmful effects of air pollution. Scientists will also be better equipped to understand how the different systems in the body react differently to exposure.

In addition to her research, Snow has been very active in leadership roles in organizations such as the Society of Toxicology Postdoctoral Assembly and the Rho Tau chapter of Graduate Women in Science.

Snow’s presentation, entitled ‘Coconut, Fish and Olive Oil- Rich Diets Modify Ozone Induced Metabolic Effects,’ is one of many by EPA scientists at the largest toxicology meeting in the U.S. For a complete list of all EPA researchers presenting at this year’s SOT event, visit us at https://epa.gov/research/sot.

Kid Scientists Shine at White House Event

By Amanda Kaufman

Kaufman SoSTEm

Amanda Kaufman at the SoSTEM event.

President Obama’s last State of the Union address on January 12th called for giving everyone a fair shot at opportunity, including offering every student the “hands-on computer science and math classes that make them job-ready on day one.” The United States government, including EPA, is supporting this call by encouraging the next generation of scientists and engineers. There IS hope—and I experienced firsthand that hope with a group of young students at the White House just last week.

On January 13th, my colleague Joel Creswell and I demonstrated some of EPA’s emerging air sensor technologies research at a post-State of the Union event at the White House called the State of Science, Technology, Engineering, and Math Address (SoSTEM). SoSTEM brought in students from all over—the Bronx, Baltimore, DC, and more—to showcase innovative science and technology to excite the imaginations of the students and encourage them to follow their dreams and passions no matter how insurmountable they may seem. Over 150 students from 5th through 12th grade attended the event.

I was lucky enough to spend several hours with these kids while I exhibited a variety of portable, lower-cost citizen science air monitors. They also got to build their own air pollution sensors using LED lights, microprocessors, electrical circuitry, and particulate matter (PM) sensors using kits designed by EPA research engineer Gayle Hagler. These energetic students had lots of questions about the sensors and air pollution in general, and I was amazed by how much they already knew about both topics or just figured out as we played with the various devices.

This event also featured presentations by NASA, the Smithsonian National Air and Space Museum, the National Institutes of Health, and some words of wisdom and encouragement from White House Office of Science and Technology Policy Director John Holdren and U.S. Chief Technology Officer Megan Smith, as well as several others.

The day ended with a live question-and-answer video chat session with scientists working at the South Pole. The students lined up eagerly to ask questions about what it’s like to live at the South Pole and what kinds of challenges they face in such a harsh environment.

Throughout the day, I was constantly impressed by the vision and enthusiasm exhibited by each of the young people, which inspired me to think of what future discoveries they would bring. All this “controlled chaos of enthusiasm” was accompanied by inquiring student reporters making their rounds with thoughtful questions. It was great to see these kids link what they were seeing to school subjects, making the connection between the microprocessors used in the air sensors and those being used in their computer science or robotics classes.

With support from President Obama and others, these kids are a shining example of our future. The common message given to students throughout the day was to stick with their dreams, to never give up, and to never stop dreaming. Quoting John Holdren, “The spirit of discovery is in our DNA…You [the students] are at the core of President Obama’s vision for the future.”

EPA’s Rigorous Auto Oversight Will Get Even Stronger

By Christopher Grundler, Director, Office of Transportation and Air Quality

Last month, Volkswagen admitted to EPA and the California Air Resources Board that the company employed a sophisticated device to cheat U.S. emissions standards in certain diesel cars, including the Audi A3, Beetle, Golf, Jetta, and Passat. We take this matter very seriously. It’s not only a violation of the Clean Air Act, it threatens public health and the credibility of the industry.

Our goal is to complete a comprehensive investigation and to take the appropriate steps to ensure that this never happens again. We are now testing for defeat devices and other compliance issues for model year 2015 and 2016 light-duty diesel vehicles from all manufacturers. On September 25, we notified all auto manufacturers that our testing will include additional evaluations designed to detect potential defeat devices.

We employ a rigorous, multi-layer process to test and certify new vehicle models before they can be sold, and for testing vehicles that are in production and on the road. But technologies evolve and circumstances change, and we’re constantly looking at ways to improve our compliance and oversight programs. Over the past 45 years, our oversight and testing program has developed new tools and new techniques to adapt to technology advances so we can deliver on the agency’s mission.

In the late 1990’s, the heavy-duty industry deployed defeat devices in a large number of trucks, resulting in a settlement valued at over $1 billion. We’ve done extensive on-road testing audits for compliance with the newly implemented greenhouse gas emissions standards. This effort resulted in an enforcement action and ultimately a record-setting settlement with Hyundai/Kia, and significant fuel economy adjustments by Ford and other vehicle manufacturers.

Our testing and oversight includes both in-lab testing using dynamometers and on-road testing in real-world conditions. Both are necessary as part of an active robust program. This provides a multi-layered oversight approach focused on:

  • Testing both pre-production prototypes and production vehicles on the dynamometer, which provides accurate, reliable and repeatable measurements that can be used to compare against the standard, and across vehicle types;
  • On-road testing using portable emissions monitors (PEMs) that measure emissions during real world driving situations. In recent years, on-road PEMs testing has been focused on heavy duty diesel vehicles, which account for roughly 40 percent of the NOx pollution from on-road sources.  (By comparison light duty diesel cars account for about 0.1 percent of NOx pollution from on-road sources.)
  • Laboratory audits ensuring that manufacturer, contract, and other agency test labs conform to testing protocols and data quality standards, so that the data EPA gets from these sources (including the data manufacturers provide to EPA) meet standards and that results can be compared among labs; and
  • Holding manufacturers accountable for their actions through rigorous enforcement of the Clean Air Act, which provides a strong deterrence against cheating and helps maintain a level playing field for the vast majority of automakers that play by the rules.

Air quality monitors across the country tell a clear and compelling story: U.S. air quality has dramatically improved as a result of implementing our programs as vehicle miles and the economy have grown significantly. Since EPA’s founding, we’ve cut our nation’s air pollution 70% all while the economy has tripled. A strong oversight and compliance program is critical to ensure that the clean air standards that EPA sets for vehicles to protect public health actually deliver the emissions promised to the American people.  We will learn from this Volkswagen case, and will adapt and improve — as we have before — to ensure we deliver on the Agency’s mission.

Refining Environmental Justice

By Matt Tejada

Before joining EPA, I spent more than five years in Houston working to protect the health of the many low-income and minority communities along the Texas Gulf Coast who share their neighborhoods with oil refineries. I cannot think of a single fenceline community from my work that does not have numerous health and environmental challenges facing local residents. And while toxic emissions from refineries are not responsible for all of those challenges, the risk from refinery pollution is an ever-present part of living in these places.

A new rule we’re releasing today helps reduce these dangerous emissions – a major victory for environmental justice but more importantly for the communities living and working along the fencelines of refineries.

The rule will reduce visible smoking flare emissions and accidental releases. For the first time in a nationwide rule, it will provide important emissions information to the public and neighboring communities by requiring refineries to actually monitor emissions at key sources within their facilities and around their fencelines. The rule also increases controls for storage tanks and cokers, parts of refineries that many folks rarely think about because they have just become part of their neighborhood background. The pollution reduced from these two types of units is very significant.

The final “Refinery Rule” – as many EJ stakeholders likely know it by – will reduce 5,200 tons per year of toxic air pollutants, along with 50,000 tons per year of volatile organic compounds. That is thousands of tons of pollution that will not be coming out of our nation’s refineries every single year. The emission reductions from this final rule will lower the cancer risk from refineries for 1.4 million people. That’s not just good for the communities that live in and around refineries — it’s outstanding. And, not just for the communities, but for the folks who work inside the refineries, as well as stakeholders in the broader community whose regional air quality would otherwise be impacted by some of these pollutants.

This rule means a lot to me personally after all the time I spent in those communities in my home state of Texas. It’s one of the biggest steps we’ve taken to protect environmental justice communities under Administrator McCarthy’s leadership. But it’s not the only one – we’ve also worked to create a Clean Power Plan that protects the needs of the most vulnerable Americans, changed the way we prioritize environmental justice in our rulemaking, created EJSCREEN to help communities learn about their environmental risks, and – just this week – released new Worker Protection Standards that keep farmworkers and their families safer from over-exposure to pesticides.

As someone who has worked on the community side of these issues, I know the importance of listening to stakeholders and communities who provide valuable input as we develop rules. The final rule incorporates community feedback and has been strengthened from proposal stage to final, accounting for important concerns expressed by the very people living on the fenceline who we are trying to protect.

Our work to increase that protection is far from done, but this final Refinery Rule is a major step forward in controlling pollution from refineries to protect the health and well-being of those who live near them and it leaves the door open to continue to introduce technology as it advances and offers even greater protection. Because here at EPA we don’t see environmental justice as something to be achieved in one action – but as something we are committed to continually advancing in everything we do.
