Sustainable, Cost-Effective Refrigerant Management

In the race to decarbonize buildings, energy efficiency and electrification dominate the conversation. Behind the scenes is a powerful and often underestimated contributor to climate change: refrigerants. Used in heating, ventilation, and air conditioning (HVAC) and refrigeration systems, refrigerants, especially hydrofluorocarbons (HFCs) like R-410A, can have global warming potentials (GWPs) thousands of times higher than carbon dioxide. Despite their outsized impact, we are seeing that refrigerant emissions are frequently left out of lifecycle assessments and sustainability strategies. As regulations tighten and frameworks evolve, refrigerant management is emerging as a critical frontier in climate action. Henderson partners with organizations to take a comprehensive approach, from developing leak detection and reporting protocols to creating refrigerant transition plans, conducting lifecycle assessments, and designing leak prevention strategies that future-proof and de-risk assets.

Why Refrigerant Management Deserves Strategic Attention

Refrigerants contribute to greenhouse gas emissions in three key ways:

1. Fugitive emissions during installation, servicing, and operation.
2. End-of-life losses when systems are decommissioned.
3. Efficiency degradation from leaks, which increases energy use and Scope 2 emissions.

For example, R-410A has a GWP of 2088 (IPCC AR4), meaning that one kilogram leaked is equivalent to emitting 2,088 kg of CO₂. Over a system’s life, even small leaks can result in significant climate impact. Leaks also reduce system efficiency, which increases energy consumption and drives up operating costs. This creates a dual impact: contributing to direct carbon emissions from refrigerant loss and increasing operational emissions through higher energy use, costing the environment and your pocketbook more.

Regulatory Pressure Is Mounting

The American Innovation and Manufacturing (AIM) Act is reshaping refrigerant policy, with a phased approach that will impact every stage of the refrigerant lifecycle:

• 2025: All new HVAC&R systems must use refrigerants with a GWP of 700 or lower, effectively phasing out R-410A.
• 2026: Systems with ≥15 lbs of refrigerant charge must comply with leak rate thresholds, mandatory inspections, and timely repairs. Systems with ≥1,500 lbs will require automatic leak detection.
• 2028: End-of-life refrigerant tracking and reporting will become mandatory.
• 2029: Reclaimed refrigerants must meet EPA purity standards before resale or reuse.

In parallel, EPA Section 608 of the Clean Air Act continues to regulate refrigerant handling, recovery, and reclamation. Key provisions include:

• Technician Certification: Only EPA-certified technicians may service or dispose of equipment containing ozone-depleting or non-exempt substitute refrigerants.
• Prohibition on Venting: Intentional release of refrigerants during maintenance or disposal is prohibited.
• Recovery and Disposal: Refrigerants must be properly recovered using certified equipment.
• Reclamation Standards: Used refrigerants must meet industry purity standards.
• Recordkeeping and Reporting: Owners/operators must maintain detailed records of refrigerant additions, removals, leak inspections, and verification tests.

Together, these regulations represent a transformative shift toward greater accountability, transparency, and climate-conscious refrigerant management.

The Financial Case for Better Refrigerant Practices

Refrigerant loss isn’t just an environmental issue but a financial one:

• Lost refrigerant leads to higher operating costs and more frequent servicing.
• The average cost to refill R-410A is approximately $60 per pound, and prices may rise as phase-outs progress.
• Poor recovery practices can result in compliance penalties and reputational risk.

Refrigerant mismanagement can erode both sustainability goals and bottom lines. Henderson leverages proven frameworks to align operational efficiency with decarbonization priorities.

Elevating Refrigerant Strategy

Refrigerant management is no longer optional. As frameworks evolve and regulations tighten, the ability to quantify, track and mitigate fugitive emissions will become a core competency in sustainability consulting. Our approach helps you reach your operational and sustainability goals in a few key ways:

• Develop a Leak Detection and Reporting Protocol
  • Implement routine inspections and automated monitoring systems.
  • Establish clear procedures for documenting and responding to leaks.
• Establish Refrigerant Inventory Tracking
  • Maintain a centralized log of refrigerant types, quantities, and equipment locations.
  • Track additions, removals, and losses over time to support emissions reporting.
• Transition to Low-GWP Refrigerants
  • Evaluate current refrigerants and identify alternatives with lower GWPs.
  • Prioritize retrofits or replacements during scheduled maintenance or upgrades.
• Conduct Refrigerant Lifecycle Assessments
  • Evaluate refrigerant-related emissions across installation, operation, and end-of-life stages.
  • Use framework comparisons (e.g., LEED vs. EPA) to inform more accurate carbon accounting.
• Design for Leak Prevention
  • Advocate for factory-sealed and tested systems to reduce on-site leakage risk.
  • Include refrigerant impact as criterion in equipment RFPs and vendor evaluation.

By proactively addressing refrigerant leakage, organizations can significantly reduce both carbon from refrigerant loss and operational emissions from increased energy efficiency. These actions not only support decarbonization goals but also improve system performance, reduce maintenance and operating costs, and future-proof assets. Bringing refrigerants to the forefront of sustainable planning, we unlock a critical opportunity to drive meaningful progress toward decarbonization, and we’re with you every step of the way. We’re committed to achieving net zero carbon on all projects by 2040, leading sustainable and regenerative design for a healthier, cleaner, and more energy efficient future.
