Sustainability’s new ROI: How Organizations Turn Environmental Programs into Margin Protections

Sustainability Banner
Key Takeaways:
  • 493 hospitals reported sustainability data through Practice Greenhealth’s 2025 Environmental Excellence Awards, generating $203 million in aggregate annual savings (up 15% year-over-year) while avoiding 185,000 metric tons of GHG emissions.

  • Hospitals with a formal climate resilience plan jumped from 38% in 2023 to 61% in 2024, even as U.S. hospitals continue to generate more than 5 million tons of waste annually.

  • The regulatory environment has split in two directions: facility-level waste and pharmaceutical compliance rules remain strict and actively enforced, while broader federal decarbonization incentives have been substantially rolled back since January 2025.

  • Sterile processing departments face a persistent technician shortage, with roughly 10,900 openings (average annual openings from growth plus replacement needs) needed annually, against a workforce of just 76,500.

  • Hospital margins remain thin, closing 2025 at roughly 1.3%, even as recent Medicaid and CHIP (Children’s Health Insurance Program) cuts are expected to raise uncompensated care costs and push more rural hospitals toward closure.

  • Pathstone Partners has helped health systems capture more than $4 million in combined annual benefit across waste, linen, shredding, and EVS initiatives, evidence that sustainability and margin protection are no longer competing priorities.

Hospital sustainability has spent three decades moving from a compliance obligation to a core operating priority. What began as a response to environmental and regulatory pressure has evolved into a discipline with real, measurable financial returns, one that hospital leaders increasingly can’t afford to treat as optional. For organizations navigating today’s thin margins, the question is no longer whether to invest in sustainability, but where the returns are largest and fastest to capture.

A Movement Three Decades in the Making

The organized push for hospital sustainability traces back to 1996, when the EPA identified medical waste incineration as the leading U.S. source of dioxins, among the most potent carcinogens known. Health Care Without Harm formed in direct response, a coalition of 28 organizations that helped cut the number of medical waste incinerators from roughly 4,500 in 1996 to fewer than 100 within a decade. A 1998 agreement between the American Hospital Association and the EPA committing hospitals to virtually eliminate mercury waste laid the foundation for Practice Greenhealth, now the sector’s leading sustainability network with more than 1,700 hospital partners. Through the 2000s and 2010s, the conversation broadened from toxic waste to carbon emissions, as hospitals came to account for roughly 8.5% of U.S. greenhouse gas emissions. The financial case has since caught up with the environmental one: research shows every dollar saved on energy carries the same margin impact as $20 in patient revenue, a ratio that is difficult for any CFO to ignore.

Sustainability Timeline
Momentum is Building Across Hospitals Today

Seven in ten healthcare facilities took concrete climate action in 2024, and the percentage of hospitals with a formal climate resilience plan jumped from 38% in 2023 to 61% in 2024. The examples span both non-pediatric and pediatric systems. Providence Health System saved $46 million in 2025 through waste reduction and renewable energy. Seattle Children’s reached carbon neutrality in 2025, cutting emissions 16% since 2022 while lifting its waste diversion rate to 47.4%, and Valley Children’s Healthcare built the largest pediatric renewable energy microgrid in the country, targeting a 50% emissions cut by 2030. Boston Children’s device reprocessing and single-use item repurposing program was significant enough to be published in the American Journal of Surgery in late 2024. Pathstone’s own pediatric client work reflects this same momentum, with active initiatives underway in medical waste management, solid waste handling, and device reprocessing.

Where Pressure is Concentrated

Waste remains the most visible pressure point. U.S. hospitals generate more than 5 million tons of waste each year, roughly 14,000 tons per day, of which 20-25% is plastic, and the global medical waste management market is projected to grow from $19.73 billion in 2024 to $23.88 billion by 2028. Regulatory activity is compounding the cost: 2025 amendments sharpened the legal line between hazardous chemical waste and regulated medical waste, while the EPA and DEA have both stepped up enforcement around disposal and controlled substance handling. In response, hospitals are rethinking waste at the point of care, and the “green operating room” concept, built around better segregation and tighter control of surgical overage, is gaining real traction. Device reprocessing has emerged as a particularly high-impact lever: Ohio State University Wexner Medical Center’s partnership with Stryker Sustainable Solutions generated $1.4 million in savings and diverted 60 tons of waste from landfills.

Sterile processing departments are under similar strain. A persistent technician shortage, with roughly 76,500 medical equipment preparers employed nationally in 2024, has left three in five hospital leaders naming SPD staffing a substantial barrier to efficiency. That gap is projected to widen. The Bureau of Labor Statistics (BLS) estimates roughly 10,900 openings will be needed each year through 2034, driven by both growth and worker retirements. That means hospitals will need to fill positions equal to more than 14% of the entire workforce every single year just to keep pace. Outsourcing has become one strategic response, and the number of hospitals adopting it is expected to triple in the coming years. New sterilization technology is helping too: vaporized hydrogen peroxide systems are gaining adoption because they can safely process heat-sensitive instruments. Underlying all of this is a patient safety imperative: the CDC estimates that 1 in 31 hospitalized patients acquires a healthcare-associated infection, which keeps pressure on sterile processing departments from easing even as staffing gaps widen.

Financial and Regulatory Headwinds

These operational pressures are compounded by a  broader financial and regulatory squeeze:

  • Median hospital operating margin closed 2025 at roughly 1.3% across more than 1,300 hospitals, with labor still comprising roughly 53% of nonprofit hospitals’ expenses, leaving little room for upfront sustainability capital.
  • The One Big Beautiful Bill Act, signed into law on July 4, 2025, cut roughly $911 billion in federal Medicaid and CHIP spending over ten years, a change analysts expect will raise uncompensated care costs and push more than 300 rural hospitals toward closure.
  • Federal decarbonization incentives have been substantially rolled back since January 2025, with the HHS Health Sector Climate Pledge removed from the HHS website, and a proposal to eliminate the agency’s Decarbonization and Resilience Initiative for hospitals entirely.
  • Facility-level compliance has moved in the opposite direction, growing stricter: the EPA’s Hazardous Waste Pharmaceuticals Rule continued rolling out at the state level through 2025, and DEA enforcement around controlled substance disposal has intensified. 

The hospitals best positioned to navigate this environment are the ones treating sustainability as an operational priority rather thank a philanthropic one, since waste, energy, and efficiency programs are among the few remaining levers tat improve margin without cutting care.

How Pathstone Helps

Pathstone Partners has worked with health systems across the country to capture savings that are often hiding in existing vendor contracts rather than requiring new captial programs. Recent client examples include:

  • Medical waste and EVS: Renegotiating the medical waste contract brought the per-pound rate down from $0.40 to $0.36, delivering roughly $246,000 in hard savings; a separate EVS RFP retained the incumbent cleaning vendor at improved pricing worth $418,000 annually.
  • Shredding and linen/mop program: A shredding RFP delivered nearly $97,000 in cost avoidance, and a shift from a rental to hybrid disposable model for mops and microfibers delivered close to $1.0 million in combined pricing savings and rebates..
  • Cleaning and janitorial services: An RFP across twelve vendors generated roughly $389,000 in hard savings while preserving scope..
  • Solid waste, pest control, and EVS: Similar initiatives brought the total combined benefit across all five engagements to more than $2.5 million annually.

While the pressures facing hospital sustainability programs are real, forward-thinking organizations can differentiate themselves by treating these initiatives as margin strategy rather than a side commitment. Those acting now, often by revisiting existing contracts rather than starting new programs, will be best positioned to protect both care quality and financial sustainability going forward.

IV Fluid Shortage in 2025: Be Prepared with Pathstone

IV Fluid Shortage in 2025
Pathstone Partners’ Strategies for Supporting Hospitals

The recent announcement by the FDA regarding the ongoing shortage of IV fluid containers highlights the significant challenges facing hospitals and healthcare providers. With shortages expected to persist through March 2025, hospitals are grappling with how to meet patient needs amidst constrained supply. At Pathstone Partners, we understand the complexities of such supply chain disruptions and are committed to providing solutions that ensure continuity of care and operational efficiency.

Here’s how Pathstone Partners would help hospitals navigate this critical issue:

Standardization: Exploring Alternative Sourcing Methods

Pathstone’s team would begin by evaluating the hospital’s current sourcing practices. Many hospitals rely on long-standing vendor relationships, but in times of shortages, testing the market can reveal alternative suppliers with available stock.

  • Review existing vendor agreements for flexibility.
  • Obtain quotes from multiple vendors to identify potential alternatives.
  • Navigate contractual constraints and provide guidance if exclusivity clauses are present.
  • By diversifying supply options, hospitals can mitigate the risk of disruptions tied to a single vendor.
Utilization: Reducing Waste and Maximizing Resources

Another critical step is to analyze current IV fluid utilization processes to identify opportunities to minimize waste. For example, unused IV fluids removed from stockrooms and later discarded represent preventable losses.

  • Conduct a process review to identify waste points.
  • Develop staff education programs to optimize IV fluid use.
  • Introduce protocols for more efficient stock rotation and usage tracking.
  • These measures not only conserve valuable supplies but also foster a culture of resource mindfulness among staff.
Strategic Alliances: Partnering with Nearby Health Systems

In times of scarcity, collaboration is key. Pathstone would assist hospitals in exploring partnerships with nearby health systems to share resources and secure more favorable vendor agreements.

  • Identify geographically close health systems open to collaboration.
  • Facilitate the creation of mutual aid agreements to share IV supplies when needed.
  • Explore joint contracts with vendors, leveraging combined purchasing volumes to negotiate better terms.
  • This approach fosters resilience and resource-sharing across the healthcare ecosystem.

Optimizing Clinical Equivalencies for Bone and Biologics

Health Care Financial Consultant Clinical Supplies
Through collaboration with physicians and the supply chain team, Pathstone achieved an estimated ~$630K in annual savings.

A ~700 bed hospital in the Southern U.S. was facing financial challenges and tasked Pathstone’s clinical purchased supplies consultants with examining areas of spend that had opportunity to drive benefit. Clinical supplies is typically one of the largest and broadest areas of spend, with items ranging from pennies to thousands of dollars.

For higher cost supplies, there is often opportunity to achieve high savings (e.g., .25% – 50%) through converting to a lower-cost product at another supplier. Bone and biologic items (e.g., allografts, tendons) typically cost in the $1,000s and were identified as having high potential for savings. However, the more complex the supply, the more challenging it may be to convince physicians of clinical equivalency.

To begin, Pathstone wanted to isolate spend on bone and biologic items. The team limited scope to tissues, surgical meshes, and allografts and issued pricing proposals to several suppliers asking them to provide matching products with pricing when applicable. In many cases, suppliers were proposing 50%+ in savings.

The next, and more complex, step was to perform research on product specifications and outcomes to determine clinical equivalency. Pathstone leveraged a clinical research tool that provides a bevy of information with the intent of supporting product and supplier selection.

While the team wanted to supply physicians with all relevant data points, it was important to develop a concise comparative analysis given their busy schedules. The team had the opportunity to present the opportunities to the Chief Medical Officer and the Head of Orthopedics. Pathstone developed a relatively standardized summary view for each of fifteen conversion opportunities, with more supporting data in an appendix to pull from when necessary.

The two physicians were supportive of the potential conversions but needed to hold conversations with end users that have more product specific expertise. At times, physicians can have strong preferences towards specific products for non-clinical reasons (e.g., supplier relationship). Thankfully, there was little concern with Pathstone’s proposed conversions, and any hesitations were addressed with further research.

While physician conversations occurred, the team worked with the supply chain and contracts team to ensure that current contractual arrangements would allow for conversions. Hospitals typically have a web of local contracts and GPO arrangements with high variability of terms, spend requirements, rebates, etc. For GPO contracts, hospitals often have a tiered rebate schedule in which the more the client purchases, the higher effective discount they receive. For suppliers in which the client transitioned away from, Pathstone needed to confirm that potential price increases did not outweigh savings opportunities from converting to a new supplier.

Through collaboration with physicians and the supply chain team, Pathstone achieved an estimated ~$630K in annual savings on ~$1.8M in annual spend. For suppliers in which Pathstone moved significant spend away from, there were negligible rebate implications. Moreover, the team helped the client establish a clear process for future high-cost clinical product conversions, such as orthopedic products. Some conversion opportunities were filed away for a Phase 2 that will be reevaluated after a year.
