The Green Health Care Program (https://greenhealthcare.ca) offers resources for implementing sustainable practices in healthcare settings.

b. Climate-Informed Medical Training

Medical education should incorporate climate science and its health impacts to prepare future healthcare professionals for climate-related challenges. This includes training on recognizing and managing climate-related health conditions, understanding environmental determinants of health, and developing communication skills to discuss climate risks with patients. Schools can partner with organizations like Health Care Without Harm (https://noharm.org) to integrate climate change education into their curricula.

c. Emergency Preparedness and Response

As climate change increases the frequency and severity of natural disasters, healthcare providers must be prepared to respond effectively. This involves developing emergency preparedness plans that include climate-related scenarios, conducting regular disaster response drills, and coordinating with local emergency services. Providers should also advocate for public health infrastructure improvements to withstand extreme weather events.

4. Personal Actions for Healthcare Providers

Healthcare providers can also take personal actions to mitigate climate change and its health effects. Leading by example not only contributes to global efforts but also enhances credibility when advocating for broader systemic changes.

a. Reducing Carbon Footprint

Healthcare professionals can reduce their carbon footprint by adopting sustainable practices in their daily lives, such as using public transportation, reducing meat consumption, and minimizing energy use. Additionally, they can offset their carbon emissions by supporting reforestation projects or investing in renewable energy.

b. Sustainable Prescribing Practices

Prescribing practices can also impact the environment. Healthcare providers should consider the environmental footprint of pharmaceuticals, such as those with high manufacturing emissions or those that contribute to environmental contamination. Educating patients on proper medication disposal can also reduce pharmaceutical waste and pollution.

c. Lifestyle Counseling

Promoting sustainable lifestyle changes among patients can have dual benefits for personal health and the environment. Encouraging active transportation, such as walking or cycling, not only reduces carbon emissions but also promotes cardiovascular health. Similarly, advocating for plant-based diets can reduce greenhouse gas emissions and improve overall health outcomes.

5. Research and Innovation in Climate-Health Solutions
