Why a Defense Production Act Memo on Refrigerants Is Critical for U.S. Climate Policy
The urgent need for federal action to accelerate the transition to climate-friendly refrigerants and protect essential infrastructure.
Why We Need a Defense Production Act Memo on Refrigerants
Refrigerants are an invisible backbone of modern civilization. From food preservation to medical storage, air conditioning, and data centers, these chemicals underpin essential systems that sustain human health, economic activity, and daily comfort. Yet, many common refrigerants—especially hydrofluorocarbons (HFCs)—are also remarkably potent climate pollutants. With mounting pressures from regulatory agencies, grid reliability threats, and the urgent need to reduce greenhouse gas emissions, there’s a growing consensus that America cannot afford to take a slow, incremental approach to the refrigerant transition. This article explores the necessity for a Defense Production Act (DPA) memo on refrigerants, why federal leadership is vital, and how such action could shape the future of cooling in the United States.
The Critical Role of Refrigerants in Modern Infrastructure
Refrigerants are chemical compounds used in cooling and heating systems that are essential to food safety, healthcare, residential comfort, and technology infrastructure. Their uses include:
- Food Supply: Keeping perishables fresh in homes, supermarkets, and supply chains.
- Health Services: Storing vaccines and medicines at regulated temperatures.
- Climate Control: Providing air conditioning for buildings and vehicles.
- Data Integrity: Cooling critical data centers and technological hubs.
Despite their importance, most legacy refrigerants contribute heavily to global warming, some with thousands of times more warming potential than carbon dioxide. As the climate crisis accelerates, the transition to safer alternatives becomes not just an environmental concern but a matter of national resilience and security.
EPA’s Regulatory Push and the Phaseout of HFCs
The U.S. Environmental Protection Agency (EPA) is spearheading a phasedown of high-global warming potential (GWP) refrigerants under the American Innovation and Manufacturing (AIM) Act of 2020. This regulatory shift is beginning to reshape the market and supply chain for cooling equipment:
- The ban on new equipment using refrigerants with GWP over 150, including R-448A, R-404A, and R-507A, starts in 2025 for stand-alone commercial refrigeration, and extends to remote condensing units and large commercial applications by 2026.
- Restrictions extend to the manufacture, import, sale, distribution, and export of high-GWP RACHP (refrigeration, air conditioning, and heat pump) equipment, with phased deadlines spanning 2025–2028.
- Older facilities reliant on legacy refrigerants may require extensive equipment repair, replacement, or retrofitting to remain compliant.
Although existing products are not currently banned, EPA retains authority for further restrictions via petitions or future rulemaking. This means industry should expect ongoing regulatory tightening and temporal deadlines for compliance.
The ER&R Program: A Federal Framework for Refrigerant Management
The EPA’s landmark Emissions Reduction and Reclamation (ER&R) program aims to set a unified federal baseline for refrigerant management. Its key provisions include:
- Mandatory repair of leaking equipment and installation of automatic leak detection systems on large refrigeration units.
- Requirements for using reclaimed HFC refrigerants in servicing existing equipment.
- Technician training and proper management of HFCs in fire suppression equipment.
- Strict standards limiting the amount of new (“virgin”) HFCs permissible in recycled refrigerants.
What others are reading
If fully implemented, these measures incentivize the recovery and reuse of HFCs, reduce lifecycle emissions, and encourage the adoption of low-GWP alternatives across sectors.
Grid Stress, Extreme Heat, and the Cooling Paradox
As climate change drives more extreme heat events, U.S. demand for air conditioning and refrigeration spikes, putting increased stress on the electric grid. Essential sectors—hospitals, supermarkets, military facilities, and critical infrastructure—cannot afford interruptions in cooling, especially during emergencies:
- More frequent heat waves mean higher risks to public health for vulnerable populations.
- Grid instability during peak heat carries cascading consequences, from spoiled food to life-threatening medical interruptions.
- Older cooling systems, highly dependent on phased-out HFCs, may struggle with reliability or require urgent, costly upgrades to maintain compliance.
Transitioning to climate-safe refrigerants is therefore not just a regulatory challenge but a necessity for keeping the country’s vital infrastructure operating reliably under increasingly chaotic climate conditions.
Why the Defense Production Act?
The Defense Production Act (DPA) gives the federal government power to prioritize and direct industrial production for national defense and emergencies. Invoking DPA for refrigerants would:
- Accelerate industry conversion by prioritizing manufacturing of equipment compatible with safe refrigerants.
- Expand domestic capacity for recovery, reclamation, and recycling of legacy refrigerants to prevent supply chain shocks.
- Coordinate federal procurement to ensure all government-managed facilities become models for best practices in refrigerant management.
This approach recognizes the transition as a matter of both climate safety and national infrastructure security.
How a DPA Memo Could Accelerate Change
By issuing a DPA memo, the federal government could:
- Mobilize U.S. manufacturing to produce low-GWP refrigerants and compatible equipment at scale.
- Prioritize rapid upgrades for military bases, hospitals, disaster-relief facilities, and other key assets with aging systems.
- Support workforce training and certification for the booming service sector needed to phase in new technologies.
- Reduce U.S. dependence on foreign supply chains vulnerable to geopolitical instability or economic shocks.
Federal action could also send strong market signals to accelerate innovation, attract investment, and ensure the cooling sector becomes a pillar of climate resilience rather than a source of super pollutant emissions.
Barriers to Rapid Refrigerant Transition
Despite the urgency, several roadblocks hinder progress on refrigerant transition:
- Fragmented Standards: U.S. regulations historically lack a unified national approach, with significant variations in state laws and local codes.
- Supply Chain Lags: Ramp-up of manufacturing low-GWP equipment and refrigerants often falls behind demand; legacy systems face compatibility issues.
- Cost and Training: Retrofitting or replacing large-scale systems entails high upfront costs, especially for small businesses, and workforce skills must be updated.
- Lack of Awareness: Many operators are unaware of looming deadlines for compliance or underprepared for regulatory changes.
Federal leadership—especially via the DPA—could address these systemic gaps, solve market failures, and ensure a coordinated effort to protect critical infrastructure and public welfare.
Potential Impact on American Manufacturing and Innovation
The refrigerant transition is not only a climate and infrastructure challenge but a major opportunity for American industry:
- Domestic production of low-GWP refrigerants and compatible technologies can create good-paying jobs and position the U.S. as a leader in global cooling innovation.
- Federal funding, such as recent grants from the Inflation Reduction Act, is already supporting advances in HFC reclamation and new cooling technologies.
- Industry partnerships—connecting manufacturers, maintenance providers, and environmental advocates—can accelerate the scaling of sustainable practices.
- Effective refrigerant management sets an example for robust climate action globally, reinforcing U.S. leadership in international climate agreements like the Montreal Protocol and Kigali Amendment.
Why Rapid Action Matters For Public Health and the Environment
Delaying the refrigerant transition not only increases the risk of environmental harm but perpetuates health inequities:
- As extreme heat worsens, access to safe cooling becomes a life-saving necessity for millions, especially children, the elderly, and medically vulnerable.
- Supermarkets, schools, and healthcare facilities must upgrade now to both comply with regulations and protect public safety.
- The sooner super-pollutant HFCs are phased out, the faster the U.S. can reduce climate emissions, clean up air quality, and build resilience in communities.
Frequently Asked Questions (FAQs)
What are hydrofluorocarbons (HFCs) and why are they harmful?
HFCs are synthetic chemicals widely used in cooling systems. Although non-ozone depleting, they have high global warming potentials (GWP), some thousands of times more potent than CO2, making them significant contributors to climate change.
What does the EPA’s AIM Act mean for businesses?
The AIM Act tries to phase down the production, import, and use of high-GWP refrigerants. Starting in 2025-2026, many older refrigerants will be banned in new equipment; facilities must upgrade or retrofit systems to remain compliant.
Will existing equipment using older refrigerants need to be replaced?
Existing equipment can continue to operate, but any new installations or major upgrades will need to use compliant low-GWP refrigerants. Frequent repairs and proactive upgrades will become increasingly necessary as rules tighten.
What is the Defense Production Act and how could it help?
The Defense Production Act lets the government fast-track and prioritize industrial activities deemed essential to national security or emergency response. Applying it to refrigerant transition could coordinate supply chains, manufacturing, and workforce training for rapid sector-wide change.
How does refrigerant management support climate goals?
Smarter management—repairing leaks, reclaiming used chemicals, and using low-GWP alternatives—drastically reduces emissions, curbs demand for new super-pollutant refrigerants, and sets the stage for cleaner global cooling standards.
