Ratings & Rankings

Measuring UofL's progress in sustainability and how we compare to other institutions.

STARS Charter Participant


The primary tool used by the University of Louisville to measure our progress in sustainability is the STARS (Sustainability Tracking, Assessment & Rating System) framework developed by AASHE (the Association for the Advancement of Sustainability in Higher Education). As a Charter Participant in STARS, UofL was the first school in the region -- and the 10th in the nation -- to achieve a STARS rating; UofL was the first school in Kentucky to achieve a STARS Gold rating; and we have always enjoyed the highest STARS rating in Kentucky. Check out the map of STARS schools.

As part of our Pathway to Platinum strategic Sustainability Plan, UofL seeks to progressively improve our overall STARS rating and our score across all sections of the framework. We have been staying true to that goal since we started on the campus sustainability journey in 2008.

STARS GoldUofL has consistently improved its overall STARS score over the years, with our most recent STARS Gold rating (68.45%) in May of 2022, documenting a 2.21% improvement over our 2019 STARS Gold rating (66.24%). This was the fifth STARS report we submitted since 2011 and we continue to increase our score each time. UofL is proud to have consistently maintained the highest STARS rating of any school in Kentucky, and we rank 4th among our official Benchmark Institutions. UofL has also remained in the top 100 most sustainable schools on the planet! This steady progress in sustainability has kept UofL in a leadership role in environmental, social, and economic stewardship.

“UofL’s unwavering commitment to the health of our planet is another reason to be proud of this institution, but this is not the time to remain idle. We will and we must continue this hard work to ensure a bright future. I am so proud of our faculty, staff and students who are devoted to this issue for the university and in their daily lives.”

STARS Scores for UofL and its Benchmark Institutions 2022As the report makes clear, there is important work before us to not only maintain our standing, but to push ahead towards STARS Platinum (at 85%).

Below are some key recommendations that ought to be considered in our planning going forward. To continue making progress on sustainability, UofL must:

  • Maintain a commitment to sustainability as an explicitly stated core value of the university. Sustainability needs to be reincorporated in our strategic plan with a goal to improve our overall STARS score by at least three points in the next three years, with the longer-term goal of achieving STARS Platinum (85% or more).
  • Fully commit to our revised Climate Action Plan and devote additional resources in order to achieve these new, bolder goals to reduce our carbon emissions.
  • Ensure 100% of employees and on-campus contract workers receive a living wage with the total compensation provided to our lowest paid regular employee meeting or exceeding 200% of the living wage.
  • Make an annual snapshot of the UofL Foundation's entire investment holdings publicly available, including specific funds/companies and proxy voting record.
  • UofL STARS room for improvement as of 2022Ensure that at least 30-60% of the UofL Foundation’s investment pool is sustainably invested in: Sustainable industries (e.g. renewable energy or sustainable forestry), Businesses selected for exemplary sustainability performance, Sustainability investment funds, Community development financial institutions, Socially responsible mutual funds, and Green revolving loan funds.
  • Increase affordability and access by expanding the percentage of: entering students who are low-income or eligible for need-based aid; graduating low-income students or those receiving need-based aid; need met for students who were awarded any need-based aid; and students graduating with no interest-bearing student loan debt or for whom no out-of-pocket tuition is required.
  • P&A STARS Points Available 2022Rejoin the Worker Rights Consortium with a small fraction of the revenues from our trademark licensing to ensure that UofL apparel is not made in sweatshops.
  • Reduce waste and inefficiency in the operation and maintenance of our buildings by hiring a full-time, Certified Energy Manager; by working toward the certification of building space as LEED for Existing Buildings: Operations & Maintenance; or by developing for uncertified spaces an energy management program, a green cleaning policy/program/contract, and/or a water management program.
  • OP STARS Points Available 2022Develop a comprehensive plan to increase the percentage of renewable energy that UofL sources (on and off site) from the current 4.5% toward 80-100% in the next decade.
  • Enhance the sustainability and local impact of our food and beverage purchasing by developing plans to: 1. reduce our total expenditures on conventional animal products; 2. increase food & beverage sourcing which is third-party verified (e.g. organic, fair trade, or Marine Stewardship Council) and/or sourced from local producers within 250 miles of campus.
  • Reduce single-occupancy vehicle trips to campus and the distances traveled by commuters through a comprehensive Transportation Demand Management Plan that not only provides transportation alternatives, but addresses the abundance of subsidized, convenient parking accessed via annual permits and the need for attractive and affordable housing for students and employees to live within three miles of campus.
  • Reduce the total amount of solid waste generated by UofL per capita and hire a full-time Zero Waste Coordinator.
  • Reduce water use per capita, per square foot of building space, and per vegetated acre by up to 30% relative to 2006.
  • Increase the percentage of academic departments and courses that expose students to the concepts, skills, and knowledge necessary to understand and address the interdisciplinary challenges of sustainability - i.e. wise social, economic, and environmental stewardship.

Anyone can view finalized STARS reports from individual schools online without creating an AASHE Account. There are some additional, very useful features within the STARS Dashboard for doing research into STARS reports (particularly the Content Display function which allows you to filter down to specific credits and/or particular types of schools, etc.) that you can only access with an AASHE Account, which is available to all UofL employees and students through our institutional AASHE membership. (It’s also worth noting that with such an account you can also access all of the great materials, reports, discussion groups, etc. available in AASHE’s Resource Center). Here's how:

Step 1: If you do not have an AASHE Account, UofL students and employees may create one here (simply using your @louisville.edu email address).

Step 2: To access the full range of features on the STARS Dashboard, log-in using your email address and password associated with your AASHE Account. If you have lost or forgotten your AASHE password, you may re-set it here.

  • In Spring 2015, Purposeful Networks (formerly known as myActions) recognized University of Louisville with a Gold Level Student Actions Award. UofL was one of only seven gold-level schools out of 125 recognized nationwide. This recognition was the result of considerable effort on the part of UofL students to take and log a wide variety of sustainability actions on campus, from eating local to turning off lights to volunteering in the community. In Fall 2014, UofL received a nationally recognized sustainability award from myActions.org for “green and compassionate student actions.” The Student Actions Award recognized undergraduate schools for student leadership and progress, as well as the impact of green and healthy activities. See: UofL recognized as “green and compassionate” (The Louisville Cardinal, March 30, 2015)

Other Sustainability Rankings

UofL has also been honored in other rankings of environmental, social, and economic performance which speak to our commitment to sustainability, such as:

  • Zero Waste:
    The Post-Landfill Action Network (PLAN) has twice ranked UofL in their annual list of Top 10 Zero Waste Campuses. In October 2022, PLAN ranked UofL #8 and, in 2021, UofL ranked #7 in PLAN’s first annual list of Top 10 Zero Waste Campuses in the U.S. The rankings were earned as a result of conducting a comprehensive Zero Waste Atlas Assessment in 2020 that was designed to help campuses assess and streamline campus systems for materials management. The Post-Landfill Action Network (PLAN) gave UofL an overall Zero Waste score of 58.2% (864.5 out of a total possible 1600.5 points). This compares very favorably to the other campuses PLAN works with, which average between 40-50%. For Scope 1 surplus property and hard-to-recycle materials, UofL scored a 63.4% (427.75 + 24 additional credits out of a total possible 712 points). For Scope 2 food waste and single-use materials, UofL scored a 53.9% (437 +42.25 additional credits out of a total possible 888.5 points). This assessment laid the groundwork for the development of UofL's first Zero Waste Plan in 2021. Read the full PLAN Atlas Report here.
  • Diversity & Inclusion:

    In 2022, for the ninth year, UofL was named a recipient of the Higher Education Excellence in Diversity (HEED) Award from INSIGHT Into Diversity magazine, the oldest and largest diversity-focused publication in higher education. UofL also earned recognition for the fourth year in a row as a Health Professions HEED Award winner. The Cardinals have proven leadership as a three-time Diversity Champion, a distinction given to institutions scoring in the top tier of all HEED Award winners. Diversity Champions set the standard for thousands of other campus communities striving for diversity and inclusion. Read More.


University of Louisville is quite proud of its achievements regarding sustainability and with good reason! The university is whole-heartedly embracing the role of environmental steward. An ACUPCC signatory since 2008, UofL is committed to reducing its greenhouse gas emissions and, having already cut emissions 22 percent, plans to achieve climate neutrality by 2050. All new construction and/or building renovations are executed in accordance with Kentucky’s High Performance Building Standards using the LEED Green Building Program. The university currently boasts four LEED Gold facilities including the new geothermal Student Rec Center and four LEED Silver buildings including the newly renovated School of Dentistry. UofL is also happily exploring renewable energy. For example, Sackett Hall features a dual-axis tracking solar array (the only one of its kind in the state). This provides both electricity and hot water for the building and is 30 percent more efficient than fixed solar panels. Additionally, students and faculty are actively involved in converting Dining Services’ waste into resources for the campus. Food waste is collected, composted, and turned into fertilizer for campus gardens. Waste cooking oil is converted into biodiesel to power campus shuttles. Outside of these actions and policies, the university also hosts a number of events to encourage the Louisville community to get involved. For example, this past year UofL residents competed in Bluegrass Unplugged. This annual contest pits University of Louisville students against students from surrounding Kentucky colleges to see who can reduce electricity usage in residence halls the most. And many students eagerly attend monthly EcoReps workshops and the Sustainability Scholars Roundtable, a brown bag seminar series highlighting interdisciplinary sustainability research happening at UofL
