Healing the Planet, Healing Ourselves: Climate-Conscious Healthcare (Part 1)

In 2025, the healthcare sector faces a paradox: while it exists to heal, it also contributes significantly to environmental harm. If global healthcare were a country, it would be the fifth-largest carbon emitter. From energy-hungry equipment to single-use plastics, the sector’s footprint is growing—and so is its responsibility.

But here’s the good news: hospitals, clinics, doctors, and biomedical engineers are uniquely positioned to lead climate action. Not just because they understand health—but because they understand urgency.

The Hidden Link: Fossil Fuels and Healthcare

Most healthcare facilities don’t burn fossil fuels directly. But they rely on them indirectly—through electricity, transport, manufacturing, and supply chains.  

• MRI machines, for example, consume massive energy, often powered by coal-based grids.
• Ambulances and medical transport run on diesel.
• Pharmaceuticals and medical devices are produced in energy-intensive factories.
• Air conditioning and sterilization systems run 24/7 in hospitals.

Every diagnosis, every procedure, every pill has a carbon cost.

Creative Measures for Hospitals and Clinics

Let’s explore some innovative, practical strategies that healthcare leaders can adopt:

1. Green Energy Transitions

Hospitals can shift to solar or hybrid energy systems, especially in regions with high sunlight.

Example: A rural hospital in Maharashtra installed rooftop solar panels for its ICU and lab. It reduced grid dependency by 40% and saved ₹1.2 lakh annually.

2. Smart HVAC Systems

Heating, ventilation, and air conditioning (HVAC) systems are major energy drains. Smart systems adjust temperature based on occupancy and time of day.

Example: A Bengaluru clinic installed motion-sensor air conditioning in consultation rooms. Energy use dropped by 30%.

3. Eco-Friendly Procurement

Choose suppliers who use sustainable packaging, low-emission transport, and ethical sourcing.

Example: A diagnostic center in Jaipur switched to a vendor offering reusable sample containers. Waste generation fell by 60%.

4. Waste Segregation and Recycling

Biomedical waste is a hazard—but not all waste is biomedical. Proper segregation allows recycling of paper, plastics, and metals.

Example: A multispecialty hospital in Delhi trained staff to separate recyclable waste. Within six months, 3 tons of material were diverted from landfills.

5. Green Building Design

New facilities should be designed with natural lighting, passive cooling, and rainwater harvesting.

Example: A cancer care center in Kerala built its new wing with terracotta cooling tiles and skylights. It reduced energy bills and improved patient comfort.

Role of Doctors and Biomedical Engineers

Doctors and engineers can be climate advocates in their own domains:

• Doctors can prescribe digital consultations when possible, reducing travel emissions.
• Biomedical engineers can design energy-efficient devices and promote repair over replacement.
• Surgeons can opt for reusable surgical kits where safe and feasible.
• Radiologists can schedule imaging to optimize machine usage and reduce idle time.

Example: A radiology team in Chennai created a shared imaging calendar across departments. It reduced machine downtime and saved 15% on energy.

A Culture of Climate-Conscious Care

Climate action in healthcare isn’t just about infrastructure—it’s about mindset. Leaders must embed sustainability into mission statements, training modules, and daily routines.

Example: A hospital in Ahmedabad added “environmental stewardship” to its core values. Staff began suggesting green ideas, from composting to carpooling.
