AH Sustainability Efforts

2026/08/07

At Alexandra Hospital, we believe that caring for our patients and caring for the planet must go hand in hand. That is why we are constantly exploring innovative ways to reduce our environmental footprint while continuing to deliver excellent care to our patients and community. Our patients and community are at the heart of our sustainability efforts. Every staff member, patient, retail tenant, and volunteer plays a vital role. Together, we aim to foster a mindset shift towards more sustainable healthcare, creating a greener future for all and leaving a healthier planet for generations to come.

Alexandra Hospital has been recognized for its commitment to sustainability with the Geneva Sustainability Centre Excellence Award for Hospital Sustainability Acceleration and the Ashikaga–Nikken Excellence Award for Low-Carbon Healthcare by International Hospital Federation (IHF) at World Hospital Congress in Geneva, Switzerland. These awards highlight the hospital's efforts in achieving comprehensive sustainability improvements across operations and clinical settings, including the implementation of low-carbon care practices and energy efficiency upgrades. The hospital's initiatives have been well-received by the international community, showcasing its dedication to creating a greener and healthier future for patients and the planet.

A Green Hospital

From the wards of our Main Building to the offices in Cocoon and the green spaces across our campus, sustainability is woven into every corner of Alexandra Hospital. The map below showcases our sustainability journey across the campus, spanning the Main Building, the Cocoon, and the wider campus grounds.

Alexandra Hospital's sustainability governance is aligned to the NUHS Green Taskforce and Joint Commission Internation Global Health Impact (GHI) Chapter, spanning two levels from cluster strategy to hospital action.

Alexandra Hospital’s Go Green Group

The Sustainability Committee, led by the Chief Operating Officer, brings together Facilities, Support Operations, and Job Group Leads to drive sustainability efforts across all hospital functions. Here is how our focus areas translate into action on the ground:

Energy Efficiency
Reducing energy use across our campus
We continuously improve energy efficiency across the hospital through LED lighting upgrades and Heating Ventilation and Air Conditioning optimisation. As part of the NUHS Green Taskforce, we are working towards a 10% reduction in emissions from purchased energy against our FY2018–FY2020 baseline. Our new Integrated General Hospital is designed to meet Building and Construction Authority Green Mark Super Low Energy standards, contributing to the cluster-wide goal of having at least 50% of buildings meet SLE certification.
Waste and Recycling
Cutting waste and advancing circular economy
AH is working towards a 60% reduction in waste from our FY2020 baseline. We actively reduce clinical and operational waste through device reprocessing programmes, targeted recycling initiatives, and a green procurement policy that prioritises environmentally responsible suppliers. These efforts are underpinned by our commitment to reuse, reduce and recycle across clinical and non-clinical operations.
Green Procurement
Embedding environmental criteria into procurement
Through the NUHS Green Procurement Taskforce, AH aims to reduce supply chain emissions by 30%. We apply an enhanced price-quality-environment evaluation framework that embeds environmental criteria into purchasing decisions, ensuring sustainability considerations are weighed alongside cost and quality when procuring goods and services.
Staff Engagement

Empowering every staff member to go green
Sustainability is everyone's responsibility at AH. We engage our staff through a range of learning and experiential activities, including corporate events and community outreach such as environmental field trips and visits to sustainability facilities. These activities help build awareness and foster a shared commitment to greener practices.

Our Job Group Leads across all departments also drive green action from the ground up, supported by the HEAL (Healthcare Emissions Action Lab) simulation — a hands-on learning experience that brings sustainability decisions in healthcare to life.

Sustainable Care

Integrating sustainability into how we care
Sustainability is woven into the way we deliver care. In our wards and internal events catering, we have introduced lower-carbon menu options and removed red meat, reducing the carbon footprint of food served across the hospital.

In our operating theatres, we have phased out desflurane and nitrous oxide, potent greenhouse gases as part of the NUHS cluster commitment to eliminate their use entirely. We also continuously review other clinical pathways to reduce our environmental footprint without compromising patient outcomes.

Built Environment & Biodiversity
Building greener, cooler spaces for our community
Our campus greenery programme aims to increase the green plot ratio to 5, expanding biodiversity and reducing ambient temperatures for patients, staff, and visitors. Through thoughtful landscaping and biophilic design, we are working towards a campus that supports both human and ecological wellbeing, now and our future Integrated General Hospital.
