When you’re trying to change the world — in Phaedra C. Pezzullo’s case, by improving the environment — you need more than scholarly publications to create impact. 

It’s why one of her favorite stories involves the fact that her first solo-authored book, , inspired the lyrics to a punk-rock song by the band The Holland Dutch. 

“Something like that reaches people in more profound ways than just talking about policy or politics,” said Pezzullo, CU Boulder communication professor in the College of Media, Communication and Information (CMCI). 

In early 2025, Pezzullo opened . And while an academic lab in a formal university setting may sound out of step for someone whose work galvanizes protesters and inspires musicians, she sees it as an exciting next step in the shifting conversation around sustainability. 

“The lab is already becoming a space where people from a range of disciplines who study sustainability — students, staff, faculty and community partners — can build relationships and consider the role of storytelling in the field,” she said. 

“Something like that reaches people in more profound ways than just talking about policy or politics.”

As with any university lab, creating high-impact learning opportunities for students is key. 

Activist Becomes Academic

Pezzullo’s formative educational experiences inspired her teaching philosophy. While a graduate student at the University of North Carolina at Chapel Hill, she interviewed activists and community members in Warren County — known as the birthplace of the environmental justice movement — where landfill toxins were poisoning the water source serving a predominantly Black community. 

Listening to their voices and adding her own to the cause helped Pezzullo to see how a single story could unlock millions of dollars to clean a landfill. Cleanup work began as she completed her studies. 

“I became hooked on stories,” she said. “When we put storytelling into practice in service of complex problems, like sustainability, we discover why communication is captivating.” 

It’s part of why Pezzullo doesn’t limit her storytelling to scholarly publications. Her public-facing work on sustainability includes a podcast, , where she explores sustainability issues like plastic bag bans, disability justice and environmental treaties with other voices from the field. 

One of these voices was Emy Kane (IntlAf’13), managing director of , an organization that raises awareness about and offers alternatives to problematic plastics through partnerships with brands and engagement with companies, scientists and the global youth movement. 

“When we put storytelling into practice in service of complex problems, like sustainability, we discover why communication is captivating.”

“What inspired me most about Phaedra is her commitment to sharing stories borne from empathy and action,” said Kane. “I’m thrilled to see my alma mater support her platform and research so that the next generation of leaders are equipped with the stories they need to reimagine the systems that run our world.” 

Conversations on the podcast helped inform Pezzullo’s 2023 book, , which won three national book awards. Highlighting success stories, she said, is important to counteract the defeatism and fatalism that typically accompany sustainability stories — and she’s seeing such sentiments rising, even in her classroom. 

Oftentimes, in the wake of a victory, “people point out just how much is still wrong with pollution, with our climate, with the world,” she said. “Success isn’t that there won’t be more disasters — it’s that, with more thoughtful choices, future disasters may be less impactful. And that is a more challenging story to tell.”

Science Demands Better Stories

Amid news of rising temperatures, invasive microplastics and melting glaciers, it might seem frivolous to talk about sustainability in terms of good storytelling. But experts argue that we’ve struggled to make progress on environmental issues because the deeply scientific nature of these problems makes it hard for the general public to relate.

Robert Cox — Pezzullo’s mentor at UNC Chapel Hill, where he remains an emeritus professor — credited his protégé with laying the basis for how understandable stories can change the course on climate. 

“All the work being done to communicate climate science in the public sphere is now being talked about in terms of relatable stories that demonstrate the impact of climate change,” said Cox, a three-time president of the  environmental organization and co-author (with Pezzullo) of a textbook on the discipline. “Those stories resonate far beyond just the pages of an academic article. Phaedra’s work really laid the basis for the importance of narrative, of storytelling, to make complex environmental issues approachable.” 

“Success isn’t that there won’t be more disasters — it’s that, with more thoughtful choices, future disasters may be less impactful. And that is a more challenging story to tell.”

In her lab, Pezzullo is searching for that impact by forging partnerships within CMCI and CU Boulder to bring different kinds of expertise to the challenge of impactful storytelling — something she’s already doing as director of the university’s graduate certificate in environmental justice. She’s lectured at universities across the globe and has collaborated extensively with  on climate change. In the meantime, she and her students build digital “story maps” that illustrate how Colorado communities are affected by environmental and climate injustice.

Pursuing Stories with Confidence

Independent reporter Anthony Albidrez (MJour’24) took a foundational course in environmental justice with Pezzullo to better understand how journalism supports sustainability through storytelling and rigorous news reporting standards. 

Because of his class experiences, Albidrez turned a course project about a stream cleanup in Honolulu, where he lives, into a report detailing how the local unhoused population was blamed for a mess that, when cleaned, amounted to 16 tons of trash being removed from the Makiki Stream. 

“I don’t think a group of homeless people can drag tons of trash into a streambed, but from my research, they were receiving the brunt of the blame,” Albidrez said. “Phaedra’s course helped give me the confidence to go beyond the government numbers and explanations and find the real story.” 

Pezzullo’s ability to encourage that sort of intellectual curiosity is what Cox most appreciates about her impact. Though he’s quick to credit her with pushing the boundaries of their field, Cox most admires how Pezzullo has guided the next generation of thinkers as they seek to advance sustainability through storytelling. 

“So many of her students are pursuing academic, business and nonprofit work in this area, and that speaks to her strength as a mentor,” Cox said. “She is such an unselfish person in terms of contributing her labor to the field of environmental communication — and that’s the kind of champion a story like this needs.”

In 2015, “3D printing” still conjured up images of the absurd, the novel or the futuristic — think custom tabletop game pieces, small replacement parts, decorative novelties and even 3D-printed chocolate. 

But Maggie Grout (Mgmt’21) has never been one to think small. At just 15 years old, three years before she enrolled as a Buff, Grout walked up to her dad and asked a life-changing question: “What if we 3D-printed a school?” 

The answer, in the form of Grout’s nonprofit , would ripple out to impact not only her own future, but the futures of families and communities across the globe. 

Welcome to Bougainvillea 

In 2022, seven years after Grout’s initial idea sparked, Bougainvillea was born — a 700-square foot, 3D-printed school in south central Madagascar and Thinking Huts’ first officially completed project. 

According to  and , sub-Saharan Africa faces the highest education exclusion rates in the world. In Madagascar, the crisis is acute: three-fourths of secondary-age children don’t attend school due to issues like overcrowding and dangerous commutes. One-third won’t complete primary education, and 97 percent of 10-year-olds who finish primary school cannot read simple sentences. 

Thinking Huts hopes to change that. Bougainvillea is small but mighty, holding up to 30 students and serving as a beacon of hope for the local community and proof of Thinking Huts’ potential to address the global education opportunity gap. 

And while the grunt work of planning and preparing spanned the better part of a decade, the execution was swift — using an industrial-scale 3D printer and a cement mixture, an on-site team printed the modular wall components in just 18 hours. These units were designed to fit together seamlessly, forming a puzzle-like assembly to complete the structure. The roof, doors and windows, handcrafted by local artisans and builders, were added on several weeks later. 

Grout recalls: “When I was looking at the walls being printed, I kept thinking, ‘Oh, my gosh, this is crazy. It’s finally happening.’” 

Patience Pays Off

Thinking Huts was forged at the intersection of two different causes: education and sustainability. For Grout, they are intimately connected. 

“We know that in order for us to continue to increase access to education in these communities, we have to have a focus on sustainable building metrics,” said Kristen Harrington, director of development at Thinking Huts. “A lot of organizations focus on speed. But if you’re looking at how to build more holistic communities and better equip families and address the poverty cycle, you have to take the whole picture into account.” 

While this kind of long-term, intersectional problem-solving does not lend itself to the immediate gratification of a “quick fix” — each decision requires careful thought, planning and foresight — Grout said the result is lasting.  

“It’s not an overnight thing,” said Grout. “We’re trying to set up the next few generations to succeed and go further than us, rather than thinking of the short term. It’s a long haul type of journey.” 

A Relational Approach

For Thinking Huts, this kind of holistic approach means focusing on building strong, equitable, sustainable relationships in their partner communities. 

“Relationship building is a slow drip,” Harrington said. “It’s an opportunity for us to really assess what’s going to be able to create sustainability in these structures for generations.”  

In order to create this sense of longevity, Thinking Huts spends time building trust with community leaders and students, taking their needs and skills into account and assessing how to collaborate with local workers, builders, artisans and technicians. For Bougainvillea, this meant partnering with area manufacturers in the construction process, handing off 3D operational skills that can be applied to future construction projects.

Grout said this relationship-first ethos has roots in her years at CU Boulder, where she said the people she met were the most impactful, including her mentorship with Mike Leeds (�󾱲�’74).&�Բ�����;

“I think even now I’m realizing how critical it is to have a network of people around you,” she said. “The relationships I developed are the biggest things that I took away from school.”

CEO with a Story

Grout said her passion for educational opportunities has been a lifelong journey. Born and abandoned in a rural village in China, she was adopted by American parents at 18 months old and grew up in the U.S. 

“I think I’ve already always been more aware of how people’s lives are different from mine,” said Grout. “I had big visions from a young age, just knowing my life could have followed a very different path. That’s what drew me more to understanding the importance of education.”

The result is a work ethic and leadership style that Harrington said extends beyond her years and has garnered international attention from major media outlets like Forbes and Good Morning America. In fall 2024, Grout was featured as one of 

“Maggie has this true grit and determination,” said Harrington. “She doesn’t want any child to feel like they don’t have the access that she had because she was adopted. So now she can bring opportunity to children in the pockets of the world that often don’t see innovation.”

Honeycomb on the Horizon

For Grout and her team of 10, Bougainvillea is just the beginning. Next up is the Honeycomb Campus. Named for its design of adjoining hexagonal bases, this multi-building project will serve three remote villages on the west coast of Madagascar. The project is set to include solar power and Wi-Fi access and will impact more than 200 students ages four to 16, starting in summer 2025. 

When asked about her approach to the future and how she’d encourage other innovators in philanthropy and sustainability, Grout emphasized a sense of hope. 

“I know that what we do now will have a major impact later on,” she said. “I am trying to aspire for a legacy of change, even if it takes time.”

Imagine strolling down a sidewalk made from algae or building a wall with the help of microbes grown in a bioreactor. 

This extraordinary image may sound futuristic, but the technology is already here, thanks to Prometheus Materials, a sustainability-focused CU Boulder spinout giving concrete blocks a makeover with the help of environmentally-friendly bio-cement-making bacteria, algae and microbes. 

CU Boulder civil, environmental and architectural engineering professor Wil Srubar founded the Longmont-based company in 2021 with CEO Loren Burnett and a cross-disciplinary team of CU Boulder collaborators, including civil, environmental and architectural engineering associate professors Mija Hubler and Sherri Cook and the late Jeff Cameron, formerly of biochemistry. 

The impetus for the research group formed several years earlier around a call for proposals from the  (DARPA), the  (DoD) focused on developing new technologies for the military. 

“It sounded impossible, a bit like a Frankenstein objective of bringing building materials to life.” 

“Our charge from the DoD was to grow a material that had both biological and structural function,” said Srubar. “It sounded impossible, a bit like a Frankenstein objective of bringing building materials to life.” 

But the challenge was right for Srubar, who leads , where researchers aim to create construction materials that are in harmony with the natural world.

“We had been thinking about these concepts for some time,” he said. “But this was the first government investment in this particular area that really catalyzed an entirely new field.”

After two years of “spinning their wheels,” said Srubar, the team had a breakthrough in the lab when they made the first sample of engineered living materials that fulfilled DARPA’s requirements. Srubar said this success required looking back — way back — to life on Earth before humans. They were inspired by formations called stromatolites, stony structures built by microscopic photosynthesizing organisms known as cyanobacteria, which are among the oldest living lifeforms on the planet.

“We know nature has built really strong, tough materials,” said Srubar.

By studying the composition of coral and seashells, for example, the team figured out how to make lab-grown versions of the natural phenomena.

“You apply principles of biomimicry, you bring that process into the lab and beautiful things can happen,” he said.

Now Prometheus Materials, named for the legendary Greek god who introduced fire and other technologies to humans, is making sustainable building materials with a process that combines microalgae with other natural components to form zero-carbon bio-cement and bio-concrete with the major goal of reducing carbon emissions in the construction industry.

This is so important because making concrete — the most ubiquitous human-made building material on earth — generates massive amounts of CO2 and contributes significantly to climate change. Global cement manufacturing produces 11 million tons of CO2 every day (roughly equivalent to emissions from all the cars in the world), or about 8% of the world’s total CO2 emissions, according to the U.S. Geological Survey. And, according to the U.S. Department of Energy, demand for cement in the U.S. alone is expected to double by 2050.

As the company realizes its transformative role in the construction industry, it has raised $8 million in private funding in the past year and was awarded a role in a $10 million grant from the  (DOE) that will fund collaboration between a trio of national labs. Within this partnership, Prometheus will join other institutions in the field to establish methods for measuring, reporting and verifying CO2 removal and sequestration in cement and concrete materials. 

Environmental Stewardship

Prometheus is just one example of CU Boulder’s strong network of researchers bringing innovations out of labs and into companies that have real-world impact — the university is a national leader and spinout powerhouse, launching 35 companies in fiscal year 2024 and over 100 since 2016, according to Bryn Rees, associate vice chancellor for innovation and partnerships. Since 2000, the university has launched 44 sustainability-focused spinouts, including a dozen new companies in just the past few years, said Rees, who leads Venture Partners at CU Boulder, the university’s commercialization arm for the campus.

According to Rees and Srubar, several factors combine to make CU Boulder so effective at generating these kinds of companies: research expertise, commercialization resources, market need and an eagerness to improve our world.

“There’s such a history of environmental stewardship here at the University of Colorado, and in Boulder specifically, and that’s very much a part of our institutional fabric,” said Srubar. “We do sustainability research really well and it’s one, if not the pillar, of our education and research mission at the university.”

Rees agreed: “It’s a function of our research prowess in that area. There are many highly talented researchers who care deeply about the climate crisis, and so that’s where they’ve oriented their research.”

Those innovations could be used in lots of different ways, but Rees shared, “The innovators are saying, ‘We want to apply these technologies to really important problems.’”

For Srubar and others, the drive to make the world a better place is strong.

“It all begins with a vision and a belief that, first, the world is not static; it can become whatever you dream,” he said. “Understanding that you have the power and the potential to affect change is what really fueled me and our team.”

Rees also sees market need as critical to driving sustainability-focused ventures.

“There is an abundance of funding opportunities and demand from the market to have these types of solutions,” he said. “You’ve got the push from what CU Boulder is really good at, and you’ve got the pull from a true need for these types of solutions across different industries.”

“You’ve got the push from what CU Boulder is really good at, and you’ve got the pull from a true need for these types of solutions across different industries.”

Driving Meaningful Change

Another company with CU Boulder beginnings is the well-established, Boulder-based , founded in 2017 by Greg Rieker, chief technology officer and CU Boulder associate professor of mechanical engineering, with colleagues Caroline Alden (�ʳ�ٳұ�DZ�’13),&�Բ�����;Sean Coburn (PhDChem’14) and Robert Wright, former CU Boulder senior researcher.

LongPath harnesses quantum technology to detect fugitive methane emissions from oil and gas operations, innovation that benefits industry and investors — and the planet. The company’s breakthroughs in laser technology and quantum sensing, rooted in CU Boulder’s, created a leak detection system to do what previous approaches could not: continuously detect invisible-to-the-eye natural gas escaping from pipes on-site at oil and gas facilities.

Finding and patching those leaks is a triple win — in industry cost savings (from $820 to $980 million per year), and improved air quality and public health. LongPath’s technology can identify natural gas leaks that sicken and displace thousands of people each year and cut greenhouse gas emissions, particularly methane.

Today, LongPath’s Active Emissions Overwatch System is live at oil and gas operations in several states, covering hundreds of thousands of acres. Rieker and his team see the impacts of those systems growing each day, and he estimates that each system saves between 40 and 80 million cubic feet of methane annually.

“Every time we deploy a new system, it really is impactful,” he said, adding the team still celebrates every large leak located. “We’ll nail a big one for a customer, and that’s exciting.”

Similar to Srubar, LongPath’s founders were motivated by protecting the environment.

“Many academics measure impact in terms of papers published or citation rates. I always wanted the impact of my work to be more palpable,” said Rieker. “In 2024, LongPath stopped more than 6 billion cubic feet of methane emissions and counting. That’s impact, and that’s why we launched.”

“Many academics measure impact in terms of papers published or citation rates. I always wanted the impact of my work to be more palpable.”

Recently, the company received landmark financial backing from the DOE for a loan of up to $189 million to accelerate the scale-up of the company’s monitoring systems.

Another game-changing company making significant strides in sustainability is Louisville-based , founded in 2011, based on technology developed by CU Boulder mechanical engineering professor Se-Hee Lee and professor emeritus of mechanical engineering Conrad Stoldt (����’94).

Similar to Srubar and Prometheus Materials, Stoldt and Lee answered a call from DARPA. Their challenge was to double the energy density of a rechargeable battery.

“The metrics they wanted to reach were unheard of,” said Stoldt, but he and Lee accepted the challenge anyway. “We saw it as an opportunity… and we sat down and determined that, at least on paper, the only rechargeable battery technology that could meet the specs for the program was a solid-state battery.”

Lee and Stoldt partnered with Douglas Campbell, a small business and early-stage product developer, and chief technology officer Joshua Buettner-Garrett to start Solid Power. Along with then-mentor Dave Jansen, the team negotiated a commercialization agreement with Venture Partners (known then as the CU Technology Transfer Office), making the company an exclusive licensee to the university’s intellectual property.

What began as an idea Stoldt said was “bootstrapped” in CU Boulder labs, Solid Power is now an industry-leading developer of next-generation all-solid-state battery technology. As their name suggests, solid-state batteries (SSBs) differ from conventional batteries in that the electrolyte powering them is a solid material instead of a gel or liquid. That gives SSBs many advantages over lithium-ion batteries now widely used in electronics, toys, appliances and — critically — electric vehicles.

Solid Power’s design bests lithium-ion cells on safety, cost, durability and battery life — attributes long sought by consumers and automakers. Their technology swaps the flammable liquid in lithium-ion cells with a solid, sulfide-based electrolyte that is safer and more stable across a broad temperature range. Solid Power’s cells also easily outpace the conductivity and energy density of today’s best rechargeable batteries. The result is a smaller, lighter cell that is cheaper and has a longer-lasting charge.

Solid Power, which went public in 2021, employs many Forever Buffs and boasts major partnership deals with BMW and Ford, along with a new 75,000-square-foot manufacturing facility in Thornton.

Their continued innovation was recognized with a recent $5.6 million DOE grant to continue developing its nickel- and cobalt-free cell, and, late last year, the company began award negotiations for up to $50 million in DOE funding. With this project, Solid Power intends to launch the world’s first continuous manufacturing process, allowing the company to produce its critical electrolyte material more quickly and at a lower cost.

From Lab to Marketplace

With the burgeoning success of Prometheus and others, Srubar hopes to inspire other researchers to make the leap to the marketplace. To that end, he was recently named Deming associate dean for innovation and entrepreneurship, a new role in the College of Engineering and Applied Science focused on building bridges between labs and the marketplace.

“This is something I’m so passionate about — shining a light for those inspired and driven by a vision to see change in the world and to follow that pathway of commercialization,” Srubar said. “I think CU Boulder’s reputation will continue to grow in this space, and I’m excited to be a part of it.”

In 2023, Eddy Connors (Bus’21) and Luke Siegert (FilmSt’22) went from college roommates and fraternity brothers to startup co-founders when they launched , a marketplace for surplus food. The app aims to reduce food waste by offering “perfectly good unsold food” from local businesses at a significant discount. Since its inception, Goodie Bag has expanded nationally to over 200 partnering shops, including OZO Coffee, Charleston Bagels and Blend Juice Bar. Connors, who serves as CEO, talks about the company here. 

You came up with Goodie Bag during a CU entrepreneurship course. How did it come about? 

From the get-go, we wanted to muster up an idea that would both make positive social change and generate profit. There was an opportunity to prevent good food from going to waste by connecting it to people at lower prices. That business idea ended up winning the “Startup Summer” pitch competition.

How did you and Luke go from college roommates to business partners?

As roommates, we would always talk about different business ideas, different industries that needed to be shaken up. We both knew there was so much opportunity to create better outcomes for people and our planet, and that excited us.

What were some of the biggest challenges you faced in scaling the business?

In the beginning, our biggest challenge was figuring out the technology of our app since Luke and I were not engineers ourselves. We also faced some team challenges that required difficult conversations early and often as we took the company from a school project to a full-time business. Team is everything.

With over 200 partner shops and 45,000 meals saved from going to waste, what are your next big goals for Goodie Bag?

Our greatest goal is to ensure no good food goes to waste. That’s the vision that guides us. As for what’s next, we want to increase our presence in existing markets by partnering with more shops in cities like Denver, Boulder and Fort Collins.

Reflecting on your journey from CU student to CEO, what advice would you give current students interested in launching their own businesses?

Do it! In all seriousness though, just remember that inaction is always the wrong answer. Know that you’re going to have failures along the way, but as long as you’re able to learn and adapt, it’ll be a worthwhile experience.

What do you want people to understand about sustainability?

Sustainability is the most pressing issue facing humankind in the 21st century. We need to ensure that human life continues on the planet in a manner that gives everyone the opportunity for a life worth living. There is a misconception that sustainability is a STEM (science, technology, engineering and math) issue — that it’s a problem for scientists and engineers to solve. But sustainability is a human challenge. Our failure or success will affect each of us, and we must work together across disciplines to implement solutions.

CU Boulder will soon welcome its first vice chancellor for sustainability. How will this position influence future campus efforts?

I am thrilled that we’ve hired Andrew Mayock, chief sustainability officer for the federal government since 2021, as our inaugural vice chancellor for sustainability. I’ve charged Andrew with advancing CU Boulder’s reputation for bringing climate solutions to life. As the “face of sustainability” for our campus, he will take an inclusive and interdisciplinary approach to build on our legacy and make CU Boulder a household name for sustainability impact across Colorado, the United States and around the globe. I know he is eager to get started!

How can alumni and friends of CU Boulder get involved in sustainability efforts? 

We’re always looking for partners who are willing to share their insights, time and financial support to advance CU Boulder’s vision and support our incredible sustainability-focused research and teaching. You also can be an ambassador for CU Boulder in your own communities — tell your friends, neighbors and prospective students about what we’re doing in sustainability! Explore how you can minimize your carbon footprint and address issues of concern in your own cities. If you are an employer, you can also engage with CU Boulder on implementing climate action strategies in your company or workplace.

In five or 10 years, what evidence will show that CU Boulder has advanced in sustainability?

As a campus, we will pursue some “quick wins,” while also working on priorities that take more time and effort. I want to see CU Boulder lead the charge in making Colorado the most sustainable state in the nation. In the coming years, we’ll aim to advance both climate education and the implementation of solutions across the United States and beyond, transforming the way higher education drives sustainability.

When it comes to getting to class at CU Boulder, “not having a car” would be a tough sell for tardiness — the university prefers students not to have one at all. 

“We have a whole toolbox of programs to prevent students from needing to bring a car to campus,” said Brandon Smith, CU Boulder assistant director of sustainable transportation. 

Most of these offerings are free. All students receive  (RTD) bus passes and also have access to the university’s electric Buff Buses, , CU NightRide, bike repairs on campus and summer bike storage. A CU ski bus even offers students trips to several ski resorts for $25 round trip.

And Buffs take advantage. In an average week, Buff Buses log about 30,000 boardings, 90% of which are students. In 2023, students rode RTD more than a million times. From January 2023 to November 2024, students took more than 1.3 million trips on BCycle bikes. 

The payoffs for sustainable transportation are big. 

“More than 60,000 commuters travel into Boulder per day, and 80% of these are single occupancy vehicles,” said Smith. “However, less than 12% of students drive solo to campus. Imagine what Boulder and campus parking, traffic and air quality would be like if we didn’t have programs that got most students out of single-occupancy cars.”

The first officially celebrated “Earth Day” on April 22, 1970, marked the start of another green legacy: the CU Environmental Center.

A novel concept at the time, the center was founded by environmentally conscious students and acted as an on-campus organization for students to gather, develop and lead projects relevant to environmental issues. Since its inception, the “E-Center,” as it’s commonly known, has led sustainability initiatives, launched programs and partnered with green campus operations such as CU’s renewable energy campaign. 

Financed by student fees since 1973, CU Boulder’s E-Center remains the largest student-led environmental center in the nation in terms of funding and employee support. Its innovative creation more than 50 years ago has inspired many other schools to model their student sustainability programs after CU’s.

“The E-Center is governed by students, funded by students and powered by students,” said Marianne Moulton Martin, E-Center associate director. “Many of our current programs would not have been realized without student leadership and initiatives.” 

Driven by passionate Buffs, the center offers a variety of programs that aid sustainability efforts, including a composting program (started in 2004), a campus pollinator garden (installed in 2014) and the Sustainable Buffs program — which invites students to explore how they can live, connect and lead sustainably. The center’s current priorities include developing sustainability leaders, identifying solutions to environmental issues that can be implemented beyond campus, helping CU Boulder reach zero waste and zero emissions, and promoting Buff pride through positive environmental impact. 

From the recycling program created in 1976 to the first CU Bike Station in 2004, the E-Center has a green legacy that generations of Buffs have carried forward — with its student employees at the helm. In addition to the programs and services the center carries out, its student employees help engage their peers in meaningful conversations about everything from climate justice to environmentally friendly practices in labs. 

“As a key partner in sustainability on campus, the E-Center aims to support every student who wants to create a positive change in their community,” said student employee Megan McLemore (IntlAf’26). “So we also act as a liaison, helping students join or start projects they are passionate about, and connecting them with the larger community of Sustainable Buffs here at CU Boulder.” 

“The E-Center is governed by students, funded by students and powered by students.”

When a CU Buffaloes football player gets injured, coach Deion Sanders enlists a team of professionals to ensure a swift recovery. That’s what professor James Brody does with students at the College of Music’s Musicians’ Wellness Program (MWP).

that 90% of professional musicians experience playing-related pain or injuries due to misuse or overuse, and 80% of college-aged musicians report stress, anxiety or depression tied to their craft.

In response, Brody founded the MWP in 2003 to help students prevent and recover from injuries, sustain peak performance and maintain robust mental health throughout their careers.

“It became glaringly obvious this was a necessity when students came to me with injuries 20 years ago,” said Brody. “I was committed to finding ways to make a difference.”

The MWP was among the first of its kind, predating the National Association of Schools of Music’s 2005 mandate requiring music programs to address wellness. Since its inception, Brody and the MWP have expanded services and recently shared their work at three international conferences.

The program teaches performance psychology and exercise techniques for breathing, hearing and vocal health. It also includes on-staff therapist Matthew Tomatz, who provides therapy sessions to support students’ emotional well-being, including managing performance anxiety.

After 47 years of teaching, Brody will retire as director of the MWP on July 31, leaving behind a legacy that will continue to positively influence the health of College of Music students, faculty and staff — and wellness aspirants across the globe.

“The fact that we’ve already helped so many to continue to do what they love is truly gratifying,” he said.

With a search for a new director underway, Brody hopes the program will receive expanded funding to introduce initiatives like a certificate in musicians’ health, onsite physical therapists and medical professionals and hearing protection devices for students. But one thing’s for sure: Brody’s revolutionary vision ensures the program’s lasting impact on future generations of musicians.

Azza Kamal wears many hats — besides teaching sustainable planning and urban design in CU Boulder’s Environmental Design (ENVD) department, she is an urbanist, policy researcher, and licensed architect in Egypt with a passion for building better and just cities. Her work tackles some of the toughest challenges in urban planning — housing instability, affordability and equitable development — while incorporating cutting-edge geotechnology and a commitment to social and environmental sustainability. 

What is sustainable planning and urban design?

Many factors affect sustainability — walkability, resource allocation, population density and the relationship with cars and the transit system. Sustainable planning examines how these factors intersect and addresses policy gaps that impact how and where people live, how they move around the city and the cost for all of this.

What is the link between social and environmental justice and sustainability?

Sustainability without social equity is a problem for everyone. It drives up costs — when we design and build beautiful, green-certified buildings, they often become unaffordable for large portions of the population. This exclusion can increase our carbon footprint, even as we aim to reduce it. Balancing housing affordability with sustainability is complex. We need to ensure we’re not just adding asphalt and concrete but creating livable, environmentally sound spaces that meet the needs of both people and the planet.

What’s an example of these consequences?

When there isn’t enough affordable housing near transit hubs and jobs, low- and moderate-income individuals often have to live farther from their workplaces. This leads to long, costly commutes, which can consume 60% or more of some households’ income while also increasing emissions. Everyone should have access to high-quality, healthy, walkable communities designed with strong environmental policies.

What is the solution?

Developers must be aware of community needs, supported by policies that ensure underserved populations benefit from sustainable, high-quality development. Both affordability and sustainability should be lenses for every project we build and every policy we create at the city and state levels. Otherwise, we risk solving one issue while exacerbating another. It’s complicated to advocate for these policies, but educating students to become thoughtful planners is essential. This is how we can move things in the right direction.

What major changes have you witnessed in urban planning?

For years, local governments have approached urban planning in silos — different departments working independently without much connection. But in the last 10 to 15 years, as we’ve seen more tangible impacts of climate change, cities have begun to adopt a more connected approach. Departments of sustainability are looking at the built environment from a holistic,  performance-centered approach: how developments are shaped, how people move to jobs, schools, goods and service areas and how infrastructure interacts with sustainability goals. This perspective is crucial if we’re going to design resilient cities for the future.

What does your day to day look like at CU?

My primary role is teaching and research, but I’m also part of an interdisciplinary team addressing housing affordability in the Mountain West. When I arrived at CU Boulder in January 2024, we received a seed grant to model affordability forecasts for Boulder County. We’re analyzing data to understand what areas are affordable, how the housing market is behaving and the characteristics of households in different areas. This research supports future policies that promote equity in housing access.

What other policy gaps are you addressing in Boulder and across Colorado?

Colorado has made strides in emissions reform, particularly through policies tied to some typologies of affordable housing like ADU [Accessory Dwelling Units] and minimum parking requirements. But the state hasn’t yet measured how impactful these changes are and whether they suffice growing demand for low-cost housing or whether they meet the target emission reduction. That’s the next step — quantifying their effects. This spring, I’m working with students to study developments around transit hubs. We’ll analyze how reducing parking requirements impacts density, increases non-car commuting and reduces CO2 emissions.

What drives you to make an impact?

Justice for everyone. Developing according to the status quo might be easier and faster, and often more profitable, but it eventually harms us all. We must approach development with social and environmental justice in mind, ensuring that those who need affordable housing don’t fall through the cracks. High-quality, affordable housing should be the norm, not the exception. That’s far more important than flashy, high-end buildings.

What brought you to CU Boulder?

Colorado is known for its high quality of life, and the Environmental Design program is multidisciplinary, focusing on social and environmental justice. It’s one of the best programs for educating students on these critical issues. CU also attracts a high percentage of out-of-state students, giving it a broader impact. I see this as a privilege — I get to mentor students who will carry these lessons back to their communities and make meaningful changes wherever they practice.

How does technology fit into your work?

Technology is a powerful tool for planners. For example, we can use virtual and augmented reality to engage communities in urban design projects. When people see realistic models of proposed changes, they’re more likely to support them. This type of community engagement fosters trust and collaboration, helping us create solutions that reflect real needs and concerns.

Is there anything else you’d like to add?

Although my work seems complex and high-level, it’s rooted in connectedness — every decision we make impacts what we build, how we build and whom we build for. If we don’t consider these connections, we risk falling short of our goals. Teaching this can be challenging because it does not rely on linear thinking, as it involves so many intersecting factors, but I’m optimistic that multidisciplinary collaboration will equip the next generation with the skills and perspectives to make a real and lasting difference.

Close your eyes and think about sustainability. What images and colors come to mind? Perhaps you see green, outdoorsy images of the natural environment. But as we work toward a greener future, we’ll also see metal and concrete — brown and gray — people and labs, bricks and batteries, communication and ideas. 

Sustainability is critical for the future of communities and the broader world, and its efforts are driven by entrepreneurs, scientists and creative thinkers.

CU’s focus on sustainability also zooms in on the individual. It asks: What does it take for people to thrive as they pursue their passions? A multi-layered approach must be thoughtful, methodical, collaborative.

Inside this issue, you’ll find the stories about advancing sustainability in areas that include renewable concrete, 3D printing and more holistic practices for musicians. And there are a few treats, including a personal essay about the Dark Horse and a story about CU’s No. 1 superfan: Peggy Coppom (A&S ex’46).

Happy reading!
