Ultra-Low Temperature (ULT) freezers, also known as -70- and -80-degree freezers, use immense energy. The Ultra-Low Temperature Freezer Program, established in 2015, aims to reduce the number of inefficient, under-utilized and abandoned freezers and to incentivize the purchase of highly efficient ULT freezers. Funded by the Energy Reduction Fund (ERF) in Facilities & Real Estate Services (FRES), this program provides incentives through a rebate for freezer recycling and purchasing new, highly efficient freezers. Applicants can also qualify for freezer recycling and new freezer purchasing with the replacement rebate. The Ultra-Low Temperature Freezer Program has provided more than 300 rebates.

Program Structure

This program is only applicable to ULT freezers; ordinary refrigerators and freezers are not eligible for this program. Eligible freezers must be installed in/recycled from university-owned and/or operated properties. UPHS and university satellite locations are not eligible for this program. Rebates only apply to freezers with an efficiency within the program's specified range. Energy efficiency is based on the ENERGY STAR ULT Freezers Test Method. The graduated rebate amounts are based on energy efficiency and ERF criterion, each School and/or Center must fund at least 20% of the efficiency measure.

Rebate Types:

  1. Freezer Recycling Rebate: This rebate provides $500 for decommissioning and recycling a ULT freezer. The freezer owner is responsible for the removal and disposal of the freezer’s contents. Proof of recycling is required to receive this rebate, including a certificate of recycling and vendor receipt. The selected recycler must be certified under the Responsible Recycling ("R2") Standard for Electronics Recyclers OR the e-Stewards Standard for Responsible Recycling and Reuse of Electronic Equipment ("e-Stewards®"). University-preferred vendors include:
  2. Freezer Replacement Rebate: This rebate provides $1,500-$3,000 towards replacing inefficient ULT freezers with a new highly efficient ULT freezer. This rebate combines the components of the Freezer Recycling Rebate and New Freezer Purchase Rebate. Proof of purchase of a new freezer and recycling of an inefficient freezer is required to receive this rebate, including a certificate of recycling and vendor receipts. The selected recycler must be certified under the Responsible Recycling ("R2") Standard for Electronics Recyclers OR the e-Stewards Standard for Responsible Recycling and Reuse of Electronic Equipment ("e-Stewards®"). See the chart below for rebate rates.
  3. New Freezer Purchase Rebate: This rebate provides $1,000-$2,500 towards purchasing a new highly efficient ULT freezer. While we encourage the replacement of existing inefficient freezers over new, avoidable purchases, additional new freezers may be necessary and can qualify for a rebate if an energy-efficient model is selected. Proof of purchase is required to receive this rebate, including a vendor receipt.

Our Plan

Students gathered in a circle on the lawn in spring under a flowering tree on Penn campus

100% carbon-neutral by 2042

Penn's Climate & Sustainability Action Plan (CSAP) is our roadmap to a cleaner future. 

Outlining the steps forward to achieve our University’s ambitious environmental sustainability goals, CSAP challenges the ingenuity and commitment of Penn. One such goal, a 100% carbon-neutral campus by 2042, is audacious yet achievable through the many programs and initiatives championed by Penn Sustainability.

The CSAP would not be possible without the unwavering commitment of our faculty, students, and staff in solving environmental issues. Every five years a new update to the original Climate Action Plan (circa 2009) is released. And, benchmarks and expectations grow with every new plan released.

Climate & Sustainability Action Plan 4.0

The fourth iteration of Penn’s Climate and Sustainability Action Plan (CSAP) marks a milestone in our evolution as one of the world’s premier teaching and research institutions for sustainability. Building on our legacy, CSAP 4.0 reflects Penn’s continued commitment to advancing environmental scholarship, fostering innovative policies, and adopting best practices to enhance campus efficiency and reduce emissions.

CSAP 4.0 integrates sustainability and climate-conscious design across Penn’s campus, operations, and management, while expanding goals for teaching and scholarship in climate, the environment, and sustainability. It builds on the successes of earlier plans—CSAP 1.0 (2009), 2.0 (2014), and 3.0 (2019)—to address the rapidly changing environmental landscape.

Key Features of CSAP 4.0

CSAP 4.0 Cover
  • Alignment with the University of Pennsylvania Health System’s inaugural sustainability plan.
  • Inclusion of civic engagement sustainability goals.
  • Expansion of scope beyond the West Philadelphia academic campus to encompass:
    • University of Pennsylvania Health System
    • Morris Arboretum
    • New Bolton Center
    • Penn-owned real estate properties

This comprehensive plan sets ambitious 2024-2029 goals, blending measurable targets such as carbon emissions reductions with the development of new initiatives to drive progress over the next five years.

Teaching & Research

Complex challenges such as climate change and loss of biodiversity require collaborative solutions. The Environmental Innovations Initiative is dedicated to leveraging the considerable academic strengths of the University of Pennsylvania to meaningfully impact the critical environmental challenges of our time and foster impact-oriented connections between disciplines. Launched in 2020 and housed in the Office of the Provost, the Initiative is built around a vision of informing the transition to a more resilient society and fostering harmony with nature. 

Through its inclusive and dynamic programming, seed funding, and interactive tools, it has facilitated collaboration across disciplines, formed strategic alliances with external partners, and elevated the visibility of Penn’s assets. The Initiative and Penn Sustainability collaborate to support the academic components of the Climate and Sustainability Action Plan, promote environmental literacy and action through campus-wide events like Earth Week and Climate Week, and ensure sustainability throughout both the operations and the scholarship of the University’s schools and centers.

Academic Climate Commitments

In 2022, each of Penn’s 12 Schools launched its own academic climate commitment. Tailored to the disciplines of the schools, these statements showcase pathways to integrate sustainability into any professional pathway. As a facet of this, the Environmental Innovations Initiative has curated a growing list of selecting degrees, concentrations, and certificates related to sustainability.

“During pre-orientation, I took part in PennGreen. We went on camping trips, visited sustainable businesses in Philadelphia, and met with professors and people from the Penn Sustainability Office. It was a great experience, and I am now a leader for the Eco-Reps group.”
