Global Green and Healthy Hospitals (GGHH) released its 2025 highlights, detailing a year of strong momentum, geographic expansion, and the transition from climate ambition to decarbonization.
In 2025, the GGHH network grew to over 2,300 members across 88 countries, marking a 14% increase in new memberships. As the world’s largest global community of institutions working toward environmental health approaches its 15th anniversary, this growth signals a meaningful shift: sustainability is no longer an "extra"—it is becoming core to how health institutions operate.
"We prepare to enter GGHH’s 15th year with immense gratitude and admiration for our members' commitment and impact. This is coupled with enthusiasm and excitement for where we will go together as we open up the next chapter of our journey", says Nick Thorp, Senior Network Director. "The momentum we see isn't just about numbers; it’s about a deepening of commitment and ambition that is driving real-world solutions for sustainable, climate-resilient health care."
A network in action
The report highlights a pivotal move from ambition to implementation. One in four GGHH members has made commitments to the Health Care Climate Challenge, and the Race to Zero for Healthcare also expanded into new territories and communities, welcoming in 2025 participants from Ghana, Kenya, Oman, Nicaragua, and Uruguay.
Collaboration remains a cornerstone of this progress. Through the Community of Action for the Reduction of Emissions (C.A.R.E.), members in Europe, Latin America and the Caribbean, and the Pacific gained the practical, locally relevant skills needed to reduce emissions while fostering peer-to-peer learning.
Perhaps the most striking takeaway from the report is that the "sustainable hospital of the future" already exists— built piece by piece across the GGHH network. From Colombia to Malaysia, members are innovating and implementing the components of a sustainable, climate-resilient facility system that protects both human and environmental health.
This global blueprint is being realized through strategic shifts to renewable energy, breakthroughs in medical device circularity and sustainable procurement, the adoption of reusable textiles, and reductions in single-use plastics and waste.
By advancing these solutions, GGHH members are collectively proving that sustainable, climate-resilient health care is not only possible but also better equipped to meet today’s and tomorrow’s challenges.
Looking ahead
The progress showcased in this year’s report reflects more than scale. It serves as a barometer indicating the growing strength of a global community transforming health care for both people and the planet.
As GGHH prepares for its 15th anniversary, the 2025 report serves as a springboard for deeper engagement. With the network primed to address the intersecting crises of climate change and plastic pollution, the focus for 2026 and beyond is clear: stronger action, greater impact, and collective transformation.
