In 2020, the University announced its goal to be carbon neutral by 2040. This goal is 10 years earlier than the previous one, set in the original 2009 Climate Action Plan. (Jon Gardiner/UNC-Chapel Hill)

 

History

In 2007, The University of North Carolina at Chapel Hill became a charter signatory of the American College and University Presidents’ Climate Commitment. In 2009, Carolina published its first Climate Action Plan. 

The 2009 Climate Action Plan established 15 near-term strategies for carbon neutrality. Carolina has implemented 75% of these strategies, resulting in a significant decrease in greenhouse gas emissions, despite increasea in campus square footage and in the campus population.

In 2019, both the Intergovernmental Panel on Climate Change and the U.S. Federal Government issued reports emphasizing the need for immediate climate action and the potential consequences of not taking action. The responsibility of being a leader in climate action has never been greater for Carolina than it is now. The 2021 Climate Action Plan represents the first step of our renewed commitment to sustainability, together. This plan accelerates the carbon neutrality goal by ten years and includes new strategies to reach this goal.

A static report released every 5-10 years is not the most effective way to plan for carbon neutrality. Because the technologies, ideas, and resources available to Carolina can change quickly, the Climate Action Plan should be able to as well. For these reasons, Carolin has created this web-based Climate Action Plan that can be updated as our progress and plans evolve.

Report Highlights

To see updates on emission reduction projects, see Appendix A and the Greenhouse Gas Inventory Report.

  • Carbon neutrality goal: 2040
  • Progress: 37% GHG emissions reduction since 2007 baseline year.
  • Energy efficiency: Progress on emissions made despite a 21% increase in square footage and 18% increase in population,
  • Campus steam use: Per square foot, 41% decrease.
  • Campus electricity consumption: Per square foot, 25% decrease.
  • Stationary combustion: Carolina reduced its coal use at the cogeneration plant by 67%.
  • Purchased Electricity: 48% decrease due to efficiency projects and a cleaner grid.

Inventory

Since 2007, Carolina has completed an exhaustive GHG inventory annually. The graphic above depicts the results of the annual inventory. Since the 2007 baseline year, the University continues to reduce its GHG emissions, despite significant campus growth.

For a detailed trend report, visit our SIMAP emissions reporting page.

 

Goals

Because of the urgent and immediate need for climate action, Carolina has set new, more ambitious greenhouse gas goals.

  1. Carolina aspires to comply with Governor Roy Cooper’s Executive Order 80 which calls for a 40% statewide reduction of greenhouse gas emissions by 2025 and Executive Order 246 which calls for a 50% statewide reduction by 2030.
  2. Carolina will strive to achieve net-zero greenhouse gas emissions by 2040, instead of 2050.

To reach these aggressive targets, the University needs the input and support of its campus community. Carolina is committed to transparency in our progress, successes, and limitations. By challenging circumstances that may preclude projects or change priorities, Carolina will maintain openness as progress towards these goals continues.

 

Net Zero by 2040

Net-zero emissions refers to the balance of human activities that contribute to carbon emissions and processes that remove that carbon from the atmosphere. To accomplish this, emissions coming from vehicles and energy generation can be limited. In addition, new technologies can be implemented to remove carbon from the atmosphere. 

 

The Path to 2040: Project Prioritization

To meet the goals listed above, Carolina must take many actions over the next 20 years. Some actions have been identified, and many more are yet to be realized.

To utilize Carolina’s resources efficiently, over the next ~5 years, projects, strategies and initiatives will be evaluated on the critieria below. These criteria are not weighted and considerations of current budgets, needs and priorities will factor into final decisions.

Lowers Greenhouse Gas Emissions: While projects of all sizes will be considered, Carolina will prioritize projects that have the potential for large greenhouse gas reductions. As these projects are completed or ruled out, smaller projects will be elevated.

Co-Benefits: Projects with environmental, social, and equity benefits will be prioritized.

Technically Feasible: Regardless of the impact and benefits, projects must be technically feasible to be considered. While Carolina strives to be innovative in its approach, technologies must be at least semi-proven.

Financially Feasible: Carolina seeks to meet carbon neutrality in the most cost-effective way. The net present value of each project is compared to the emission reduction potential to get a NPV/MTCO2e figure. This figure is used to compare the financial viability of each project. Projects with positive net present values will be prioritized. The capital cost (relative to the emission reduction) will also be considered.

Practically Feasible: A project’s practical feasibility is determined by factors such as climate, geography, infrastructure, etc.

Excitement: It is important to get the campus community excited about efforts to reduce greenhouse gas emissions. Projects that are highly visible and draw attention to the effort are more attractive.

Living Learning Lab Impact: Due to Carolina’s mission as an institution of higher learning, projects that allow students, faculty, and staff to explore, research and learn are prioritized.

 

Strategies

Carolina has identified 23 strategies to reduce greenhouse gas emissions. These strategies could reduce emissions by 79% compared to the 2007 baseline.

Figure 2. This graph illustrates the potential impact of each broad strategy to reduce emissions. It shows high-level strategies for reducing greenhouse gas emissions.

 

Energy Strategies

Due to the size of campus, the amount of intensive research being conducted, and the steam needs of labs and UNC Hospitals, Carolina uses a lot of energy every year. Some of this energy comes from onsite sources such as the cogeneration facility, and some is purchased from Duke Energy. While both Carolina and Duke Energy are working to lower the greenhouse gas emissions associated with energy production, much of the energy used still comes from fossil fuels and releases greenhouse gases. Each year, the energy used in buildings on campus directly and indirectly contributes to roughly 70-75% of Carolina’s greenhouse gas emissions. Reducing emissions from campus energy use can be done in two general ways: reducing energy use and using cleaner energy.

Energy Efficiency

Reducing energy use on campus is the first step to decreasing energy-related emissions. By reducing energy use in buildings, Carolina lowers the associated greenhouse gas emissions while creating financial savings and possibly improving occupant comfort.

Carolina’s Energy Management team constantly works to increase the energy efficiency of existing buildings and new builds.

 

Energy Efficiency Strategies
Continue energy conservation measures program.
Continue building optimization program.
Update building design guidelines.

Stationary Combustion

Not only does Carolina have a high demand for steam, the supply must be extremely reliable to keep the hospital running and maintain sensitive research. The repercussions of campus energy outages can be immense, including loss of life or lifesaving research. To meet the campus steam demand, and maintain extremely high levels of reliability and resilience, Carolina needs to have multiple fuel options and be able to store fuel on site. Unfortunately, this means that Carolina currently uses fossil fuels to create steam.

Carolina is working to move the cogeneration facility away from coal as quickly as is technically and financially feasible. Currently, the University has increased natural gas use. While transitioning to natural gas is significantly lowering campus emissions, Carolina is still researching better long-term solutions. Until an alternative fuel source is found to minimize emissions while also generating the necessary steam output, Carolina utilizes the following strategies to reduce emissions in the short term while planning for a long-term sustainable solution.

 

Stationary Combustion Strategies
Eliminate coal use.
Explore next generation fuels.
Update building design guidelines.

Purchased Electricity

Carolina’s cogeneration facility produces roughly 15-20% of the University’s annual electricity use. Remaining electricity purchased from Duke Energy typically accounts for 20-25% of Carolina’s annual GHG emissions. There are three additional ways Carolina can continue to reduce purchased electricity emissions: onsite renewable generation, renewable energy purchases and Renewable Energy Certificate (REC) purchasing.

 

Purchased Electricity Strategies
Increase on-campus renewable energy.
Procure renewable energy.
Purchase Renewable Energy Certificates (RECs).

 

Transportation Strategies

Commuting

Commuting is one of the few upward-trending emission categories, with the exception of 2020 and 2021. This increase is largely due to more employees and students driving alone to campus, rather than using more efficient transportation. Reducing commuting emissions relies heavily on influencing individuals to make sustainable commuting decisions.

 

Commuting Strategies
Encourage/aid Chapel Hill Transit transition to electric buses.
Increase engagement in Commuter Alternative Program.
Study parking pass structure.

Air Travel

Being a global research university means domestic and international air travel. Carolina’s faculty, staff and students fly over 80 million miles annually for research, conferences and studies. Though this travel is often essential in making Carolina a leader in research, it is normally responsible for 10% of Carolina’s GHG emissions.

 

Air Travel Strategies
Explore green air travel program.
Explore voluntary or mandatory carbon offsets.

Fleet

Carolina’s fleet, which consists of around 900 vehicles, produced roughly half a percent of Carolina’s total emissions in 2021. Since 2007, fleet emissions fell 23%, primarily due to decreased fuel consumption and increased use of alternative fuels B20 and E85. The University is currently pursuing the strategies below to further reduce emissions.

 

Fleet Strategies
Optimize vehicle choice.
Increase use of biofuels.
Expand use of vehicle telematics.

 

Education and Research Strategies

As an institution of higher learning, simply reducing greenhouse gas emissions is not good enough. Carolina has a responsibility to educate and engage its community members to ensure that climate action occurs both on and off campus. With almost 30,000 students, and over 12,000 employees, this is a huge task, and equally large opportunity. Meeting Carolina’s sustainability goals will be much easier and impactful with full campus engagement.

 

 

Education and Research Strategies
Create peer-to-peer sustainability program.
Increase engagement in New Student Orientation, Week of Welcome, and other events throughout the year.
Launch Green Office Certification program.

 

Other Strategies

Greenhouse gases are sometimes used as part of operations including in switchgear and as refrigerants. In the case of switchgear, newer technology is available that doesn’t require the use of greenhouse gases for insulation. For refrigerants, climate-friendly alternatives may be available depending on the equipment being used. Carolina will continue to substitute when feasible.

 

 

Other Strategies
Replace SF6 switches with solid-state dielectric switches.
Replace refrigerants with climate-friendly alternatives.

 

Sustainable Together

The challenge of reducing greenhouse gas emissions to reach carbon neutrality and meet our climate goals requires collaboration across all levels of Carolina. With ambitious plans for climate action also comes the need for funding. While most of the strategies and ideas outlined in this Climate Action Plan rely on decisions made at the institutional level, individual behaviors adopted by the Carolina community will be the key to realizing our ambitions.

As opportunities to connect and collaborate on individual behavior change continue to develop, Sustainable Carolina will facilitate these efforts. For ideas on the actions you can take to reduce emissions and create a more sustainable campus, please visit Sustainable Carolina’s Resources web page. This web page also includes a feedback form where you can send your idea for emissions reduction strategies to us.

By learning about the quantified emissions impacts of everyday choices, communicating greenhouse gas messaging to peers, and staying aware of new tools that shrink greenhouse gas footprints, the Carolina community moves toward our new ambitious climate goals together.

Commercial MailReduce the amount of junk mail or undeliverable mail sent to campus.In 2016, Carolina adopted a Waste-Free Mail Program to reduce junk and undeliverable mail.Ongoing
Chiller Efficiency UpgradesThree projects to replace or upgrade chillers to more efficient models.Many chiller efficiency projects have been completed. Emissions from chilled water operations fell 56% (‘09 to ‘21).Complete
Heat-Recovery ChillersCapture heat from chiller condensing unit for HVAC use, rather than venting.Heat recovery chillers have been installed, assisting in the 59% decrease in chilled water emissions.Complete
Behavioral InitiativesOutreach and training to encourage occupants in energy savings.Carolina continuously engages the community through several different outreach programs.Ongoing
Energy Conservation Measures (ECMs)Improve energy efficiency in existing buildings using Energy Conservation Measures.Due to the completion of many energy efficiency projects, Carolina’s energy use intensity fell 37% since 2003.Ongoing
Green BuildingAdhere to NC Senate Bill 668 energy efficiency requirements (30% below ASHRAE standards).Ongoing improvements in building energy efficiency and retrofit projects have decreased EUIs across campus.Ongoing
Vehicle FleetIncrease fuel efficiency of campus fleet based on CAFÉ standards.Due to mileage reduction, use of efficient vehicles, and increased biofuel use, fleet emissions fell 30% (‘09 to ‘21).Ongoing
CompostingExtend composting to additional campus dining facilities and residence halls.By expanding to more food service sites, compost collection increased 62% from 2009 to 2019.Ongoing
Landfill GasCapture and combust landfill methane.System was installed in 2012. As of July 2021, the system had achieved ~330,000 MTCO2e in emission reductions.Ongoing
Business TravelTeleconferencing facilities and technologies have improved, and air miles decreased 15% between 2009 and 2019. Air miles reduced significantly during the pandemic, as well.Improve teleconferencing facilities to decrease air travel.Unknown results
20% Coal SubstituteReplace 20% of coal with torrefied wood.This strategy was adopted under certain assumptions about torrefied wood and wood pellet technologies that failed to materialize. Wood pellets were tested in 2010 and 2011. Carolina is currently researching other biofuels, electric boilers, and carbon capture technologies to lower emissions.Incomplete
Commuter TravelAvoid parking construction and increase public transportation (light rail).This strategy hinged on the completion of the Durham-Orange Light Rail Transit project, which has been indefinitely suspended. More commuters drove to campus in 2019 than in 2009, but emissions remained flat due to commuters living closer to campus and using more efficient vehicles. A Bus Rapid Transit project is currently under development.Incomplete
