The "GREEN Hospitals Act" aims to enhance the climate resilience and sustainability of medical facilities across the United States. It proposes substantial funding through amendments to the Public Health Service Act, authorizing $100 billion for fiscal year 2026 to support construction and modernization projects. These projects are designed to increase capacity for essential healthcare and update facilities to withstand climate disasters and public health crises. Priority for these grants will be given to projects that incorporate resilience measures such as onsite distributed generation for energy independence during outages, high-efficiency HVAC systems for air quality and temperature management, and green infrastructure like wetlands and drainage ponds to protect against flooding and wildfires. The bill also supports upgrades to protect access routes to medical facilities and the long-term maintenance of decarbonization infrastructure. Furthermore, the Act establishes a separate $5 billion Planning and Evaluation Grant Program to help eligible entities develop comprehensive "sustainability and resiliency plans." These planning grants, capped at $500,000 each, will fund activities like feasibility studies, climate-risk assessments, and community outreach. A significant focus is placed on ensuring that at least 50 percent of these planning grant funds benefit environmental justice communities. Applications for both construction and planning grants must include assurances regarding fair labor practices, specifically adherence to Davis-Bacon Act prevailing wages and either a collective bargaining agreement or a policy protecting employees' rights under the National Labor Relations Act. The Secretary of Health and Human Services will prioritize facilities serving Medicare and Medicaid beneficiaries, uninsured patients, and those located in or serving populations disproportionately affected by environmental burdens and climate change.
