As part of CU Boulder’s ongoing commitment to addressing climate change and reducing environmental impact, the campus launched several transformative sustainability projects over the course of the year. These initiatives not only serve as practical steps toward a more sustainable campus but also often align directly with the goals outlined in the Climate Action Plan (CAP), which was finalized in April. They will help increase energy efficiency, reduce carbon emissions and position the university as a leader in sustainability.

Here’s a look at five major sustainability projects introduced this year and how they will help achieve CU Boulder’s long-term environmental goals.

The addition of 4 electric Buff Buses

In a move to reduce transportation-related emissions, CU Boulder won grants to purchase four new electric buses. These buses are fully electric, replacing older diesel-powered vehicles and reducing greenhouse gas emissions associated with campus transportation.

Chancellor Justin Schwartz shared, “Transportation is one of the largest contributors to our campus’s carbon footprint. By switching to electric buses, we are not only reducing emissions but also providing a cleaner, quieter and more efficient transportation option for our students, staff, faculty and visitors.”

Building efficiency projects

Improving energy efficiency in campus buildings has been a critical priority, and this year CU Boulder undertook a large-scale building efficiency project. This initiative involved retrofitting 18 buildings with energy-efficient lighting, optimizing HVAC control systems, upgrading components in the heating system and modifying water fixtures for efficiency. The upgrades will reduce energy consumption by up to 11%.

“We’re committed to transforming our physical infrastructure into more sustainable spaces,” Vice Chancellor for Infrastructure and Resilience Chris Ewing said. “This project not only reduces energy use but also makes our campus more comfortable for students and staff, with the added benefit of lowering operational costs in the long run.”

Geothermal grants

Thanks to two significant geothermal grants through the Colorado Energy Office, CU Boulder is studying whether geothermal energy is feasible for the campus. If successful, this renewable energy solution would help reduce reliance on fossil fuels for heating and cooling, providing a more sustainable alternative that aligns with the CAP’s goal of achieving carbon neutrality by no later than 2050.

Schwartz noted, “The geothermal project represents a major step toward reducing our carbon footprint and showcases the university’s dedication to investing in long-term sustainable energy solutions. By harnessing the earth’s natural energy, we are setting a strong example for future generations of students.”

Hiring a new vice chancellor for sustainability

To further strengthen the campus’s commitment to sustainability, Schwartz announced the search for a new vice chancellor for sustainability this year. This strategic move ensures that sustainability is integrated into every facet of campus life and that sustainability goals are met in an effective, measurable way. The vice chancellor will focus on enhancing CU Boulder’s global reputation and impact as a transformative leader in sustainability.

“Our new vice chancellor for sustainability will play a key role in advancing our climate action efforts,” said Schwartz. “With this leadership in place, we will be better positioned to reach our sustainability targets and keep sustainability at the forefront of our institutional priorities.”

On-campus solar array and virtual net metering program

CU Boulder has made strides in expanding solar energy capabilities through two projects. A new solar array will be built on East Campus, which is  a 1.1 megawatt (MW) ground-mounted solar array on a 2-acre site east of parking Lot 560.

In addition, the campus has enrolled in a virtual net metering solar program, which harnesses power generated off campus and, after entering the local grid, applies it to our campus portfolio to cost effectively reduce our Scope 2 carbon emissions. In partnership with Pivot Energy, the agreement involves the development of a 5 MW off-site solar array in Weld County.

The combination of on-site and off-site solar power will play a major role in the campus reduction of carbon emissions.

Looking forward: A greener future

With these projects now underway, CU Boulder is working to meet the ambitious greenhouse gas reduction goals outlined in the CAP and making further investments to accelerate that progress. As Schwartz explained, “These initiatives represent just the beginning of a comprehensive approach to environmental stewardship. Our sustainability efforts are not only about achieving measurable results but also about instilling a mindset of sustainability among our students, faculty and staff.”

The collective impact of these projects will be felt across campus, from the reduction in greenhouse gas emissions to the development of a more resilient, energy-efficient infrastructure.

Schwartz envisions CU Boulder taking a leadership position for the state, nation and globe in advancing climate actions—as well as rising in global university rankings, which recently placed CU Boulder No. 11 in the U.S. and No. 61 in the world for sustainability. He noted he is encouraged by the enthusiasm across campus for focusing on sustainability, including the possibility of additional educational opportunities for students.

“Together, we are building a future where sustainability is at the heart of everything we do—ensuring our campus not only meets the challenges of climate change but leads the way toward a more sustainable, environmentally responsible world,” Schwartz said. “As we look ahead to the coming years, our focus will remain on continuing to innovate, collaborate and drive change, keeping sustainability at the core of our mission and working together to create a more sustainable future for all.”
