Other measures are asking doctors to schedule virtual appointments whenever possible and prescribe alternatives to metered-dose inhalers, which emit greenhouse gases called hydrofluorocarbons (HFCs) into the atmosphere.
Another advisory urges intensive care unit staff not to use gloves when proper hand washing would suffice.
How can hospitals reduce emissions?
Some hospitals offer more plant-based diets because raising animals for food, especially cattle, uses a lot of land and has a large carbon footprint.
Richmond General Hospital's Planetary Health food program offers plant-based meals and “climate-conscious proteins” such as steelhead trout and turkey.
Dr. Annie Lalande, who is completing her surgical training while earning a doctorate in environment and sustainability at the University of British Columbia, says the goal is to reduce greenhouse gas emissions associated with food production.
A similar six-month trial diet recently concluded at Vancouver General Hospital included dishes such as coconut chicken curry, soy sauce-based sulu joes, and Korean-style gochujang bowls made with beans.
