Climate Action Plan Draft Cover
2021 Climate Action Plan

In 2007, The University of North Carolina at Chapel Hill (Carolina) became a charter signatory of the American College and University Presidents’ Climate Commitment. Carolina then worked to develop its climate action plan which was published in 2009. In the original plan, Carolina pledged to be carbon neutral by 2050 and established 15 near-term strategies to reach this goal.

Over the past decade, Carolina has implemented 75% of the near-term strategies in the 2009 climate action plan. These strategies, along with other actions, have resulted in a 40% decrease in greenhouse gas emissions despite a 27% increase in campus square footage and a 9% increase 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 no or limited actions. The responsibility of being a leader in Climate Action has never been greater for Carolina than it is now and this Climate Action Plan is the first step of our renewed commitment to sustainability, together.

It has become apparent that 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, Carolina has moved to a web-based Climate Action Plan that can be updated as our progress and plans evolve.

2009 Climate Action Plan
Carolina’s original climate action plan contained 15 near-term strategies and several mid- to long-term strategies. The status and results of each strategy can be seen in the figure below.

Progress
Since signing The Climate Commitment in 2007, Carolina has completed an exhaustive annual GHG inventory and reduced its GHG emissions by 40% despite significant campus growth. This decrease was achieved with emission reductions in every category except for refrigerants and commuting. Carolina’s emissions since 2007, and a detailed breakdown of Carolina’s 2020 emissions can be seen below.

Since 2007, Carolina’s largest GHG emission reductions have come from:

  • Energy Efficiency – Despite a 27% increase in square footage and a 9% increase in population since ‘07:
    • Campus steam use per square foot has fallen by 49%
    • Campus electricity consumption per square foot has fallen by 24%
  • Stationary Combustion – Carolina reduced its coal use at the cogeneration plant by 52% since 2007
  • Purchased Electricity – Due to efficiency projects and a cleaner grid, emissions have fallen 44% since 2007

In the 2009 climate action plan, a business-as-usual scenario was modeled to predict future emissions with no action. With predicted increases in campus and population sizes, this scenario forecasted emissions rising to almost 800,000 MTCO2e by 2020 and over 900,000 MTCO2e by 2050. However, due to the actions described above and COVID-19 pandemic-related disruptions to campus use, Carolina’s actual 2020 emissions were 54% lower than predicted, and over 2 million metric tons of CO2e emissions have been avoided since 2010.

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

  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.
  2. Carolina will strive to achieve net-zero greenhouse gas emissions by 2040 instead of 2050.

These are aggressive targets that will require the input and support of the campus community to be reached. 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.

collapse Goals

The Path to 2040
To meet the goals listed above, Carolina will have to take many actions over the next 20 years. Some of these actions have been identified, and many more are yet to be realized. The sections below detail Carolina’s project selection criteria and the strategies that are being considered for the next ~5 years.

Project Prioritization
To utilize Carolina’s resources as efficiently as possible, all potential strategies and initiatives are evaluated based on the following criteria. 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.

collapse Project Prioritization

Strategies
Carolina has identified 25 strategies to reduce greenhouse gas emissions. These strategies have the potential to reduce emissions by 79% compared to the 2007 baseline. The high-level strategies can be seen in the diagram below and all strategies are explained in full detail in the following sections.

Energy Strategies

Energy Efficiency

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. Below, the strategies for both using less energy and utilizing renewable and clean energy sources are laid out.

The first step to lowering energy related emissions is to reduce energy use on campus. 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 is constantly working to increase the energy efficiency of both existing buildings and new builds. Thanks to these efforts, Carolina’s energy use intensity, the energy used per square foot, has fallen 37% since FY2003. Carolina is currently working toward Governor Roy Cooper’s Executive Order 80 which calls for a 40% reduction in energy use intensity by 2025.

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, this is being done by increasing 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 which minimizes emissions while generating the necessary steam output, Carolina is using the following strategies to reduce emissions in the short term while planning for a long-term sustainable solution.

Explore Carbon Capture
Description: Regardless of the fuel used, combustion results in carbon dioxide emissions. Carbon capture and storage technologies can be used to mitigate these emissions, regardless of the source.

Status: Carolina is currently researching technologies that provide carbon capture and storage.

TBD TBD

Purchased Electricity

Carolina’s cogeneration facility produces roughly 15-20% of the electricity used annually by the University. The remaining electricity is purchased from Duke Energy which typically accounts for 20-25% of Carolina’s annual GHG emissions. Other than energy efficiency, which was mentioned above, there are four ways Carolina can continue to reduce purchased electricity emissions: onsite renewable generation, renewable energy purchases, Renewable Energy Certificate (REC) purchasing, and virtual power purchase agreements. Each mechanism, and its associated benefits and drawbacks is explained below.

Purchased Electricity Emission Reduction Strategies
Strategy Total Emission Reduction Potential (%) Cost of Emission Reduction ($/MTCO2e)
Increase On-Campus Renewable Energy
Description: Carolina will continue to install rooftop solar PV on campus through additions to new and existing buildings. The pace of these installations will depend on funding and planned renovations and new builds. A 2019 study by Energy Services identified 38 campus rooftops that fit preliminary site requirements for solar PV. If solar systems were installed on all identified locations, roughly 5MW of capacity could be added. This would cover roughly 2% of Carolina’s annual electricity use.

Status: Carolina currently has solar PV on three buildings, totaling 43.8 kW. Several additional rooftop installations are in the planning process, and a 376kW ground-mounted solar project is scheduled for completion at a satellite campus in 2021.

Procure Renewable Energy
Description: In North Carolina, third party sales of electricity are prohibited, meaning Carolina must purchase all electricity from Duke Energy. Duke Energy currently has three programs for renewable energy purchasing. Unfortunately, none of these programs work well for Carolina in their current forms. Carolina is currently analyzing potential ways to make these programs work or create new programs that would allow Carolina to procure renewable energy.

Status: Ongoing

21% TBD
Purchase Renewable Energy Certificates
Description: If Carolina were unable to procure renewable energy through Duke Energy, renewable energy certificates could be purchased. Renewable energy certificates will only be used if Carolina cannot purchase renewable electricity.

Status: Renewable energy certificates have been researched but not purchased to date.

Transportation Strategies

Commuting

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

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, the individual behaviors that all members of the UNC community adopt will be the key to realizing our ambitions.

Opportunities to connect and collaborate on individual behavior change will continue to develop now and into the future, and Sustainable Carolina is committed to facilitating them through an open process. For ideas on the actions you can take to reduce emissions and create a more sustainable campus and an opportunity to leave your own idea for emissions reduction, please visit the “What Can I Do?” web page and leave a note through the feedback form.

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

Acknowledgments

Developing this climate action plan required a campus-wide collaboration. Thank you for all of the help in developing this. The following groups provided data or insights that helped form this plan: Carolina Dining Services, Energy Management, Energy Services & Sustainability, Fleet Services, Office of Waste Reduction and Recycling, Study Abroad, The Town of Chapel Hill, Transportation and Parking, and Travel Services.

Feedback and Updates

This Climate Action Plan is a living document. We originally released it in draft form to start the discussion with all members of our community in ways we can improve it. A modified stakeholder engagement strategy was used due to pandemic-related challenges. This strategy included a feedback form to capture ideas, suggestions, questions, and concerns that closed on June 15, 2021. Since many individuals had similar questions, we grouped the feedback by themes and are sharing it in the table below. As progress is made towards our carbon neutrality goal, we will continue to update the plan.

Questions and Answers
Q: Why doesn't the plan include measures to reduce water use or waste production?
A: Efforts pertaining to water, waste, and other sustainability issues are ongoing even though these topics are not necessarily mentioned in this plan. They are part of the broader strategy-forming process within Sustainable Carolina and the Carolina Sustainability Council.
Q: How has the pandemic affected emissions on campus?
A: The COVID-19 pandemic has brought an ongoing set of operational challenges that will have lasting impacts on how we function as an institution and as individuals. The emissions impacts of adjusted operations such as telework are still being analyzed as data is collected. Fewer people on campus will likely lower building energy use, waste production, and emissions from commuting.
Q: How will the University support more electric vehicles on campus?
A: UNC-Chapel Hill is exploring ways to increase electric vehicle adoption among campus users and the university-operated fleet. This effort includes installing more electric charging stations around campus. Additionally, as the development of electric vehicles continues and more types become available on the market, the feasibility of replacing existing vehicles at the end of their useful life will be considered.
Q: How can the University support Chapel Hill Transit in reducing emissions?
A: While UNC-Chapel Hill does not operate the Chapel Hill Transit system, it does provide $7 million annually for its operation. Three electric buses are currently on order, one of which was paid for by the student-run Renewable Energy Special Projects Committee (RESPC).
Q: How will carbon offsets be leveraged for carbon neutrality?
A: Carbon offsets will be considered to lessen the impact of irremovable emissions. These include air travel for study abroad programs, research needs, and athletic events as well as commuting. The current strategy is to reduce emissions as much as possible, then offset remaining emissions.
Q: Can the University install an anaerobic digester to transform food waste into fuel?
A: UNC considered installing an anaerobic digester to create fuel from food waste. This system could eliminate some methane emissions for the university. The technology was determined to be infeasible based on cost, size constraints, and logistics.
Q: Why aren't affordable housing efforts outlined in the plan since shortened commutes create emissions benefits?
A: While this is a timely concern, the ability to deliver nearby, affordable housing is not within the scope of UNC operations. Affordable housing initiatives necessitate the involvement and funding from multiple stakeholders primarily local municipalities and developers.
Q: Does UNC offer incentives for zero-emission commuting?
A: The existing Commuter Alternatives Program at UNC serves as an ongoing incentive for lowering commuting emissions. Further information can be found here.
Q: Can UNC implement vendor selection criteria to encourage sustainable purchases?
A: Many sustainable purchasing guidelines are currently implemented within the procurement systems at UNC. An example includes the prioritization of recycled paper suppliers which contributes to decreased emissions resulting from paper purchases.
Q: How will UNC leverage institutional research to reduce emissions?
A: A framework for expanding sustainability research is outlined as an objective within the CAP.
Q: How is Carolina Dining Services (CDS) supporting individuals who want more sustainable food options?
A: In collaboration with the student group Vegans for Peace, CDS developed a menu with a wide variety of vegan-friendly proteins, vegan pizza with Daiya cheese, and Meat”Less” Mondays during which 15% less meat is offered.
Q: Is the University able to purchase electricity sourced from renewables?
A: Current North Carolina regulations prohibit a customer from purchasing electricity from unregulated third-party providers, such as those commonly associated with solar installations of various scales. Not being able to enter a power purchase agreement with third parties poses a barrier to obtaining competitively-priced renewable energy in accordance with our charter to deliver services to the public of North Carolina at the lowest cost to taxpayers. The policy landscape is ever-evolving, and we are committed to continuously monitoring and evaluating our options. A current policy option that is explored in the CAP is the Green Source Advantage program offered by Duke Energy, which is intended to allow specific customers in North Carolina the ability to purchase renewably-generated electricity through Duke Energy directly. This strategy is being actively investigated, and many schools in the UNC system are assessing the cost and contractual terms. For local installations, UNC-Chapel Hill currently has a renewable energy project in progress at the former Horace Williams Airport, a combination of a solar array with a storage battery that will be used primarily for research and education. Solar arrays are already in place atop the Student Union and the North Carolina Botanical Garden. The feasibility of expanding rooftop solar installations on campus has been assessed by Sustainable Carolina. We found that maximizing rooftop solar, while acknowledging constraints such as structural and historical limitations, could satisfy up to 5% of campus electric demand.
Q: Why does the cogeneration plant combust fossil fuels?
A: UNC-Chapel Hill uses steam to sterilize medical instruments, generate electricity, heat buildings, and control humidity. Since steam is a local product and cannot be purchased from a utility the way that electricity can, UNC utilizes boilers to generate steam and a district energy system to distribute the steam to campus customers. The boilers currently operate with a mix of natural gas and coal with a higher percentage of natural gas each year in an effort to use less coal. Since natural gas emits fewer GHGs than coal, natural gas is viewed as a short-term solution. There is a continuous effort to research and test alternative fuels that provide the resilience required to operate a large campus and multiple hospitals. Any solution needs to meet the feasibility criteria detailed in the Climate Action Plan.
