Opportunity
Facility decarbonization presents a range of opportunities and benefits to hospitals in addition to meeting regulatory obligations. Energy efficiency increases both patient safety and care quality¹. Advanced control technologies contribute to leaner operations, reduced utility consumption, and lower operating costs. Resilience measures provide critical life safety backup in emergency situations. Viewed in this light, decarbonization mandates represent more than just compliance obligations, they represent real opportunities to improve your facility’s infrastructure, as well as institute new operational best practices for the benefit of your patients, employees, stakeholders, and community. There are genuine financial opportunities to be seized has well. According to the EPA, every dollar in revenue that a nonprofit hospital saves on energy is equivalent to generating $20 in new revenues. For-profit hospitals can raise their earnings a penny per share by reducing energy costs just 5 percent.²

Why It's Important to Act Now
Greenhouse gases (GHGs) and the climate change that results from their release pose an imminent threat to the health and well-being of our communities, our state, and the global environment.
Hospitals and other healthcare-related buildings are currently responsible for 8.5% of all carbon emissions in the US, and 4.4% of all carbon emissions worldwide³. They are the second largest consumer of energy per unit of floor area, second only to food services4. Hospital HVAC and water heating systems are the primary contributors to their facility emission profiles5.
Hospitals must begin to upgrade their systems with solutions that reduce emissions and conserve energy, while still retaining the operational reliability and resiliency that is crucial to high quality of care and optimal patient outcomes.

“Decarbonization” Means Different Things to Different Industries & Market Sectors
In the building industry, decarbonization refers to two different types of carbon emissions. The first type is “operational carbon” which refers to the GHGs that are emitted as a result of the the day-to-day operation of the facility. The second type is so-called “embodied carbon” which refers to the GHGs emitted during the production of the construction materials that make up the buildings themselves (concrete, steel, insulation). At this time, the guide will only concern itself with reducing the first type of carbon — operational carbon. However, additional resources on embodied carbon can be found here and will be incorporated at a later date.
The Environmental Protection Agency (EPA) classifies carbon emissions somewhat differently. GHG emissions that emanate from the facility as a result of the burning or consumption of fossil fuels are what the EPA calls “Scope 1” emissions. GHG emissions that result from the consumption of fossil fuels by off-site utilities are known as “Scope 2”. Emissions related to equipment or materials that are received from suppliers, or that arise from other aspects of your hospital’s value chain are known as “Scope 3”.
This guide concerns itself only with Scope 1 and Scope 2 emissions, the two types of emissions that a facility manager can directly control, either through on-site changes to hospital facilities or energy conservation measures (though Scope 3 emissions of remain a concern).

Confronted with a Task of Such Scale & Magnitude,
It Can Be Easy to Feel Overwhelmed.
The best way to start the process of resilient decarbonization is by taking the first few steps forward. At your facility, those first steps might be simple, common-sense energy-saving tactics like upgraded light fixtures or higher-efficiency equipment.
Get a few of these quick-and-easy wins behind you, and what seemed impossible suddenly feels achievable. Remember: you don’t have to have all the answers right away. The most important thing you can do right now is get started.
