Emergency Physician, Yellowknife

Dr Courtney Howard is an Emergency Physician in Yellowknife, in Canada’s subarctic and board president of the Canadian Association of Physicians for the Environment. Motivated by work on a Médecins Sans Frontières (Doctors Without Borders) pediatric malnutrition project in Djibouti, and by climate-related health impacts on her Northern patient population, she spends approximately half of her time working at the intersection of climate change and health.

In the pursuit of improved planetary health Dr Howard has researched the respiratory and wellness impacts of Yellowknife’s extreme wildfire season of 2014 and led the first randomized controlled trial comparing tampons to reusable menstrual cups. 

Dr Howard has been involved in policy and advocacy work on coal phase-out, active transport, plant-rich diets, integrating health impact assessments into environmental assessments, carbon pricing, and the health impacts of fracking. She led the successful campaign to have the Canadian Medical Association divest its reserves of fossil fuels and for MD-Financial to create fossil-fuel-free equity and bond funds for Canadian physicians to invest in, and is very involved in assisting medical learners in Canada and internationally to see climate change and health included in their curricula.

Dr Howard is on the steering committee of the Planetary Health Alliance,  represents CAPE on the board of the Global Climate and Health Alliance, is the Co-Chair for North America of the WONCA working group on the environment, and sits on the boards of the Canadian Medical Association, Health in Harmony, and her local environmental NGO, Ecology North.
