Climate Change

According to the World Health Organization, climate change is the “single biggest health threat facing humanity.”1 It affects cardiovascular health globally due to air pollution and extreme heat.

In Canada, air pollution is responsible for over 15,000 premature deaths annually2 and half of those are related to ischemic heart disease and stroke.3 Air pollution accounts for ~20% of cardiovascular disease deaths globally.4, 5 Extreme heat is the second major climate change-related factor that directly impacts cardiovascular health.6

Climate change working group

In 2021, the CCS formed a Climate Change Working Group who develops and steers our work in this space. The working group’s objectives are to:

  • Raise awareness about the effects of climate change and mitigation strategies;
  • Promote and adopt individual and collective climate actions, including climate actions as a professional Society; and
  • Advocate for policy change in support of climate action and cardiovascular health.
