Over the past several years, many biopharma laboratories have made measurable progress in sustainability by upgrading to more energy-efficient equipment and expanding recycling programs. But improving sustainability doesn’t end with these changes. For labs focused on temperature-controlled workflows, refrigerant chemicals are another important driver of emissions that receives less attention but can have an equal impact.
Many cooling systems used throughout research and development rely on fluorinated gases, also known as F-gases. F-gases are man-made greenhouse gases with high global warming potential (GWP). For reference, hydrofluorocarbons (HFCs), a type of F-gas commonly used as refrigerants, can carry GWPs hundreds to thousands of times greater than CO₂.
As the European Union, the United States, and other policy frameworks accelerate efforts to eliminate many F-gas refrigerants, any lab’s refrigerant strategy is becoming inseparable from procurement decisions, compliance posture, and operational health.
Operational considerations to support sustainability in labs
Research environments rely on tightly controlled conditions to protect cells, biologics, and other temperature-sensitive materials across workflows. Equipment can include ultralow temperature freezers, biomedical refrigerators, centrifuges, and recirculating chillers, each with distinct operating and performance requirements.
Small leaks from any cooling system, whether from routine service, gradual degradation, or unexpected failures, can cause environmental harm while also increasing the maintenance burden and risk of disruption. Labs must be able to reduce refrigerant climate impact without compromising temperature stability, uptime, or sample integrity.
Many labs operate mixed equipment fleets, often across multiple vendors and equipment generations. That diversity can complicate the transition to lower-GWP refrigerants for a couple of reasons.
One reason is that refrigerant needs vary by equipment category and usage frequency, meaning that some equipment is at greater risk of leaks or issues. Another is that swapping in lower-GWP technologies may not be a 1:1 replacement for legacy equipment, requiring evaluation of operating conditions, facility constraints, and workflow impacts.
Sustainability targets must therefore be balanced against budgets, installation logistics, validation timelines, and service readiness. In many cases, suppliers must be able to support distribution, inventory planning, and compliant handling for the specific refrigerant type.
The role of supplier partnerships
Choosing the right supplier is a critical step in any lab’s sustainability journey. As the range of low-GWP refrigerant alternatives continues to grow, suppliers can help labs navigate these options by offering transparency around refrigerant types, maintenance requirements, and long-term service needs.
Suppliers who have already validated low-GWP solutions for specialized biopharma applications and are committed to delivering high-performance technology without compromising sustainability progress can help labs transition more seamlessly to more sustainable options.
Technical support is also important, as equipment using newer refrigerants may require different maintenance and specialized knowledge.
Ultimately, the labs most likely to meet their sustainability targets are those that treat their supplier relationships as true partnerships, working collaboratively to ensure that product development stays ahead of regulatory changes and that cooling solutions remain both compliant and effective over time.
Future-proof your lab’s sustainability strategy
Thinking beyond current compliance requirements is becoming a necessity for biopharma labs. Regulatory frameworks targeting HFCs are already taking shape globally, and labs that don’t consider future phasedown plans risk costly equipment overhauls that can slow research timelines. Investing now in cooling solutions that exceed current standards can help labs maneuver future regulatory shifts with far less disruption.
Because lab cooling equipment often stays in service for years, procurement decisions made today will still be in effect when the next wave of regulations arrives. Building sustainability criteria into equipment selection from the outset reduces the need for repeated upgrades and keeps workflows running without unnecessary interruption.
Refrigerants sit at the intersection of scientific precision and environmental responsibility, and their role in biopharma labs deserves strategic attention. Labs that take a proactive approach by evaluating low-GWP alternatives, partnering with sustainability-minded suppliers, and making procurement decisions with future regulations in mind will be well-positioned to protect sample integrity, honor sustainability commitments, and maintain compliance as the regulatory landscape continues to evolve.
