Carbon Financing

Groundbreaking Refrigerant Carbon Credit™ Pilot Program Rewards Grocers for Climate-Friendly Refrigerant Choices

North American Sustainable Refrigeration Council Pilot Program announced the issuance and retirement of carbon credits on behalf of grocers

LAKE FOREST, ILLINOIS: Therm, North America’s leading refrigerant carbon offset developer, today announced the successful sale and retirement of its issuance of Refrigerant Carbon Credits™ from the North American Sustainable Refrigeration Council Pilot Program. Carbon financing allows grocery retailers and other foodservice providers to switch to climate-friendly refrigerants at lower capital costs by selling the credits created by the projects through the voluntary carbon market. These projects’ Refrigerant Carbon Credits sold at a significant premium to the current rate of similar credits. Projects included refrigeration rack replacements to CO2 as well as micro-distributed and stand-alone cases.

The credits were issued by the American Carbon Registry and purchased and retired by longtime voluntary carbon market experts Climate Impact Partners on behalf of an established market participant.

“Climate-friendly refrigerants are the number one way that we can prevent further climate damage,” said Fritz Troller, CEO and co-founder of Therm. “The increasing price of carbon credits, and the undisputed permanence of RCCs, put them at a market premium, and help our retail grocer customers and food distributors by providing meaningful financial incentives.”

The credits were developed for five mid-sized grocery locations in California for customers Grocery Outlet and Raley’s, two members of the North American Sustainable Refrigeration Council. They chose to install climate-friendly refrigeration systems and forgo the use of traditional synthetic refrigerants—short-lived climate pollutants that are thousands of times worse for the environment than carbon dioxide. The impact of these traditional refrigerants is so large that, in 2017, refrigerant management was identified by Project Drawdown as the number one solution to combat climate change.

“We have many clients throughout the world who are looking for innovative new approaches to reducing emissions reaching ambitious climate goals,” said Saskia Feast, Managing Director of Global Client Solutions at Climate Impact Partners. “We are delighted to have partnered with Therm, NASRC, Grocery Outlet, and Raley’s in order to demonstrate how this type of credit can make a real impact right now.”

Cooling and refrigeration system upgrades are typically associated with high capital costs, limiting viable options to reduce climate-polluting refrigerants. Refrigerant Carbon Credits function as a type of rebate for stores, enabling them to lower the capital required to make the change.

“The success of our Pilot Program is a vote of confidence from the carbon market,” said Danielle Wright, Executive Director of the North American Sustainable Refrigeration Council. “We are seeing more and more grocers of this size who are interested in switching to climate-friendly refrigerants but can’t find the capital. This creative structure opens the door for even the smallest stores to finance their refrigerant upgrades.”

Therm works with grocers and foodservice providers of all sizes to implement climate-friendly cooling and refrigeration upgrades through Refrigerant Carbon Projects. Learn more at therm.cool. Watch their presentation on carbon financing at NASRC’s 2022 Sustainable Refrigeration Summit here.

NASRC Releases 2021 Annual Report

Naturally Better Together
Announcing NASRC's 2021 Annual Report


NASRC is proud to release our 2021 Annual Report, Naturally Better Together, which summarizes our collective progress to eliminate the barriers to natural refrigerants in supermarkets. 2021 was filled with global uncertainty, but together with our members and partners, we made unprecedented progress to:

  • Offset first costs of natural refrigerant technologies

  • Increase natural refrigerant technology options

  • Ensure service workforce readiness

  • Increase awareness and support for the transition away from HFCs

We hope you take a moment to celebrate our shared accomplishments towards building a naturally better future for supermarket refrigeration. None of this would be possible without your support.

NASRC's Top 10 Accomplishments In 2021

2021 presented the industry with new challenges, but that didn't stop our members from stepping up to accelerate our mission more than ever before!
Here's a snapshot of our top 10 collective accomplishments from 2021:

Check out our top 10 collective accomplishments in 2021!


1.Sustainable Refrigeration Summit

Hosted the first-ever Sustainable Refrigeration Summit to bring together over 900 supermarket refrigeration stakeholders, government agencies, and policymakers to address the challenges to achieving zero emissions in supermarket refrigeration.

2. Funding Support for Natural Refrigerants

Developed new sources of funding for natural refrigerants: Authored a federal tax credit proposal that is currently in circulation, secured a buyer for our carbon financing pilot, and advanced progress to solidify refrigerant GWP as a metric for utility incentives.

3. Modular Solutions for Existing Facilities

Accelerated technology solutions to enable the modular transition of existing stores to natural refrigerants. Published a report characterizing retailer demand for natural refrigerant-based condensing units to bring more products to the US market. Accelerated the approval of a higher R290 charge limit to increase available self-contained solutions.

4. Workforce Development

Drafted a CO2 curriculum for trade schools & community colleges with ESCO Group, industry stakeholders, and HVACR schools to help build a future workforce that is well-versed in natural refrigerants. Kicked off a workforce development plan to grow the technician workforce.

5. State Incentive Programs

Secured $880,000 in incentives for 12 natural refrigerant projects in California and coordinated the grant deliverables. Mobilized our members and partners to support additional program funding. Worked with other states to share lessons learned and outline future incentive programs.

6. Retailer Leak Reduction Initiative

Formed a Retailer Best Practices Committee to facilitate a retailer-driven leak reduction initiative. Retailers drafted equipment specifications to proactively reduce refrigerant leaks over the lifespan of a system.

7. Pilot Projects & Research Studies

Initiated new field studies and pilot projects on advanced refrigeration technologies to better understand energy performance and other ongoing costs of natural refrigerant solutions. Contributed to the design of a comprehensive M&V study as part of the CARB FRIP grant program.
