CAG's New Climate Change Committee

The Canadian Association of Gastroenterology (CAG) recognizes the impact of climate change on public and digestive health. The formation of the Climate Change Committee positions the CAG as a frontrunner in digestive health and medical advocacy for environmental sustainability in Canada.

By raising awareness and advocating for policies to mitigate climate change's impact, the committee addresses the intersection of environmental shifts and digestive health. With growing evidence linking pollution and climate change to digestive diseases, the committee underscores the urgent need for action to protect public health and our planet.

Climate Change Committee

Rapid environmental changes driven by climate change, pollution, and biodiversity loss are impacting digestive health.

  • Heat extremes can cause intestinal and hepatic dysfunction.
  • Extreme weather is associated with flooding and enteric infections; and affects the delivery of care through infrastructure loss.
  • Air, water, and soil pollution from chemicals and plastics increases the risk of intestinal diseases such as eosinophilic esophagitis, MAFLD, digestive tract cancers, inflammatory bowel disease, and functional bowel disease.
  • Access to adequate amounts of food of high nutritional content, and to clean water is under threat.
  • Urban migration and migration between countries poses challenges for digestive care.

CMA Statement on the Climate Crisis




The Canadian Medical Association (CMA) released a statement regarding the ongoing climate crisis.

Dr. Kathleen Ross, President of the CMA, states "In the past few months, we have seen the serious health effects of wildfires and severe flooding across Canada. At the Canadian Medical Association, we know that communicating the health impacts of the climate crisis is key to driving change. Slow action is akin to no action."

In partnership with the CMA, the Lancet produced a report with targeted recommendations for Canada including divesting from and phasing out fossil fuels, increasing cross-jurisdictional coordination of extreme weather event emergency management and supporting healthy, sustainable food systems.

The CMA’s ongoing advocacy to address the health impacts of climate change involves creating a net-zero emissions health system by 2050.
