Climate change, a risk multiplier, affects human health in various ways, causing unprecedented health threats by altering the frequency and severity of health problems. By 2030, an additional 250,000 deaths per year are expected due to climate change, with direct health costs projected between US$2-4 billion annually.

Strain on Health Systems

Climate change significantly strains health systems by increasing the demand for health services. Strengthening these systems, enhancing resilience, and boosting capacity are vital to responding to escalating health challenges and maintaining essential services. Countries must invest in adaptation strategies to proactively address climate-related health impacts, develop early warning systems for disease outbreaks, and enhance crisis preparedness through healthcare staff training, health information system expansion, and equipment upgrades.

Direct and Indirect Impacts of Climate Change

Direct impacts include heat-related illnesses and exacerbated chronic conditions due to rising temperatures, heatwaves, and air pollution. Impacts caused by changes in ecosystems involve an increased risk of diseases like malaria or dengue due to changes in temperatures or rain patterns and shifts in agricultural practices that raise threats of food-related illnesses. The climate crisis also increases the probability of major virus-related events like the COVID-19 pandemic. Indirect impacts encompass mental health issues resulting from climate-related hardship and disruptions to food systems that amplify food insecurity.

Healthcare Facilities and Greenhouse Gas Emissions

Healthcare facilities have an opportunity to reduce global greenhouse gas (GHG) emissions significantly. Therefore, facilities can respond to the growing climate emergency by building resilience to extreme weather events and long-term stresses to continue protecting the health of their population and through the reduction and eventual elimination of all environmental contaminants released by their operations.

Strategies for Climate-Resilient Health Systems

Two key strategies to strengthen climate-resilient health systems include securing financial resources and fostering intersectoral collaboration. International funds finance few climate change and health projects, seldom supplemented by national investments. Strengthening intersectoral collaboration at national and local levels is crucial. Investments in early warning systems for vector-borne diseases, infrastructure resilience to extreme weather events, and improved air quality monitoring can enhance climate resilience.

Role of Climate-Resilient and Low-Carbon Healthcare Facilities

In the face of climate change, the role of climate-resilient and low-carbon healthcare facilities becomes paramount. Water scarcity often challenges these facilities, exacerbated by climate change, particularly in developing countries. This impacts the quality of healthcare services:

  • Healthcare Waste Treatment: Improper treatment of healthcare waste puts over half the global population at risk and contributes to GHG emissions and air pollution. On-site wastewater treatment can enhance resilience by removing chemicals that municipal systems cannot handle.
  • Air Pollution and Healthcare Facilities: Ambient air pollution, primarily due to fossil fuel combustion, worsens with climate change, damaging vital organs. Healthcare facilities contribute to this through energy combustion, waste incineration, and procurement of goods using fossil fuels. Implementing cleaner fuels and cooking technologies can reduce air pollution.
  • Sustainable Food Choices in Healthcare: As major food consumers, healthcare facilities have the opportunity to promote health and sustainability through their food choices. Changes such as limiting meat consumption, eliminating fast food, composting food waste, producing food on-site, and hosting farmers' markets for local producers not only promote sustainability but also contribute to community resilience.

Conclusion

In conclusion, the climate crisis presents unprecedented health threats, and proactive measures are needed to mitigate these risks. The role of climate-resilient and low-carbon healthcare facilities is paramount in this endeavour. By implementing sustainable practices and investing in resilience-building measures, healthcare facilities can significantly contribute to mitigating the impacts of climate change and enhancing community health.
