Hospitals, whether nestled in bustling cities or quiet towns, serve as vital sanctuaries of hope and healing. Yet, with the mounting pressures of climate change impacting global ecosystems, the healthcare sector is increasingly called upon to expand its mission: to heal not only individuals but also the planet. In a recent discussion with Emily Carter, a pioneering sustainability officer in digital health systems, I gleaned valuable insight into how leading healthcare providers can exemplify environmental stewardship on a global scale.

Emily’s foray into healthcare sustainability was quite unorthodox. “I was working in tech,” she recalled, “but it became apparent to me that digital solutions could significantly reduce healthcare’s environmental footprint.” Her fervour for sustainability, coupled with her expertise in digital technologies, has propelled her on a mission to transform hospital operations. “Hospitals account for a substantial portion of global emissions—approximately 4.4 percent,” Emily explained. She articulated the dual challenge hospitals face: maintaining high-quality care while mitigating their environmental impact. This challenge, however, is ripe with opportunities for innovation and leadership.
A particularly inspiring example Emily shared was the progress at Vanderbilt University Medical Center (VUMC) in Nashville. Known for its vibrant music scene, Nashville is now gaining recognition for sustainable healthcare practices. VUMC’s strategic energy management programme has achieved a 25 percent reduction in energy consumption, setting a global benchmark for hospitals. “They’ve adopted intelligent building systems that modify heating, cooling, and lighting based on real-time requirements,” Emily noted. “This approach is smart, efficient, and significantly reduces waste.”
Similarly, in Israel, hospitals such as Sheba Medical Center are making headway in using digital health to lessen environmental impacts. “Israel’s telemedicine initiatives have reduced patient travel by 40 percent,” Emily highlighted. “This not only cuts carbon emissions but also improves healthcare accessibility. It exemplifies how technology can serve both people and the planet.” These initiatives illustrate the power of digital health technologies in advancing sustainable practices within the healthcare sector.
Turning to the United Kingdom, Emily expressed heightened enthusiasm. “The NHS’s commitment to becoming the world’s first net-zero health system by 2045 is groundbreaking,” she enthused. “They’re leading with renewable energy installations and constructing low-carbon hospital buildings.” The NHS’s efforts demonstrate the substantial influence large-scale health systems can wield by prioritising sustainable infrastructure and operations. However, the true distinction of these institutions as role models lies in their comprehensive approach to sustainability. “It’s not just about reducing emissions,” Emily asserted. “It’s about reimagining healthcare delivery from the ground up. Every aspect, from procurement processes that prioritise sustainable suppliers to telehealth solutions minimising the need for physical infrastructure, is being reassessed through the sustainability lens.”
Emily also emphasised the pivotal role of digital health solutions in this transformation. “Digital health isn’t merely a trend—it’s a necessity,” she stated. “It reduces the dependency on physical resources and emissions while enhancing patient outcomes.” The integration of artificial intelligence and big data analytics is paving the way for more targeted and efficient healthcare, ultimately reducing waste and unnecessary treatments. Nonetheless, Emily candidly acknowledged the challenges ahead. “Equitable access to digital health is essential,” she emphasised. “We must ensure that rural and underserved communities aren’t neglected in this transition.” Moreover, she pointed out the environmental impact of digital technologies themselves, such as energy consumption and e-waste, which must be managed to ensure a genuinely sustainable approach.
As COP29 in Baku approaches, Emily is hopeful that the achievements in Nashville, Israel, and the UK will galvanise global action. “We need to establish global standards for sustainable health practices,” she urged. “Investments in green infrastructure and knowledge-sharing are vital to support emerging countries in this mission.” Emily’s reflections underscore the broader significance of this work. “The climate crisis is a health crisis,” she said, echoing Dr Tedros Adhanom Ghebreyesus’s sentiments. “By prioritising sustainability, health systems can protect both the planet and its people. It’s a responsibility we must all embrace.”
In exploring the intertwined pathways of healthcare and climate action, Emily’s insights offer a compelling vision for a healthier, more sustainable future. Her work, along with that of countless others in the field, highlights the potential for hospitals and digital health systems to not only save lives but also safeguard the planet for future generations.
