Manage and measure: Reducing natural gas and waste leads to less GHG emissions

Ascension committed to Race to Zero, the U.S. Department of Health and Human Services Health Sector Climate Pledge, and the Laudato Si Action Platform.

• 2030: Reduce carbon emissions 50%; reduce 50% of nonhazardous waste from all sites.
• 2040: Achieve net zero carbon emissions and zero waste across all sites.

Ascension set its energy efficiency baseline in 2008, then began an environmental stewardship program in 2011. After joining the U.S. Department of Energy’s Better Buildings Challenge in 2012, the goal was met in 2017 with a 23% energy use reduction.

In 2020, Ascension held a strategic planning exercise for the sustainability program. This concluded on Earth Day 2021 with the launch of its environmental impact and sustainability program. The program maximizes environmental impact with activities in three pillars: net zero places, responsible supply chain, and healthy communities.

The program builds upon Ascension’s existing efforts in energy efficiency, waste management, and environmentally preferred purchasing. The healthy communities pillar supports the well-being of patients, associates, and communities served. 

Ascension implemented steps to achieve its carbon reduction goals. By doing so, the system overcame challenges associated with moving from energy efficiency tracking to carbon reporting. Tasks included:

• Adding a sustainability director with carbon reporting experience and an analyst to manage the data. As sustainability directly aligns with Ascension’s mission, the sustainability organization structure and related positions were approved at the executive level, along with funding to fill positions needed to successfully implement external and internal commitments to sustainability. 
• Collecting new data sources across the organization (vehicles, anesthetic gasses, refrigerants).
• Ensuring data was valid, accurate, and comprehensive. 
• Engaging an external consultant to work with the new team and establish a reporting methodology to manage internally.
• Maintaining consistent management of assumptions, such as emissions factors.

Ascension associates play a role in achieving these goals. For example, facility-based green teams help reduce carbon emissions by asking facilities managers if a site is engaged with the steam trap program.

Ascension submitted 2019 Scope 1 and 2 data to Race to Zero via Health Care Climate Challenge’s platform. Ascension will submit 2020 through 2022 data later in 2023. In FY23, the sourcing workgroup assessed GHG emissions of 61 suppliers using Carbon Disclosure Project data. Forty vendors were added to a Scope 3 emissions dashboard.

Ascension is reducing its carbon footprint to improve air quality and counteract the health impacts of climate change affecting those served particularly vulnerable communities. Examples of poor air quality occurred in 2023 from record heat in Texas and wildfire smoke drifting from Canada to Chicago.

Ascension is lowering air pollution in the regions the health system serves to help sustain the health of communities. Examples of progress achieved include:

• Submitted baseline carbon emissions data in 2022 as part of the commitment to Race to Zero. 
• Achieved two FY23 goals: reduced GHG emissions by 5% from an FY20 baseline, and reduced municipal solid waste sent to the landfill by 6% from a FY19 baseline.
• Completed green energy supply agreements in the Midwest.
• Received national awards for 27 sites of care for outstanding sustainability performance in FY23 alone.
• Saved 70,600 MMBTU since FY22 due to Ascension’s steam trap replacement program. Replacing this part results in less natural gas needed to meet heating loads, directly contributing to carbon reduction goals.

Ascension’s environmental impact and sustainability team learned valuable lessons while overcoming carbon reporting challenges, including:

• Ensuring access to and quality of data.
• Calculation methodology and remaining up to date with regulatory changes and innovation.
• Future regulatory impacts from the U.S. Securities and Exchange Commission and the Joint Commission.
• Managing local regulations in Chicago, Austin, Baltimore, and Washington, D.C.
• The need to be flexible in the short term while remaining focused on long-term goals.
