For seven years he developed programme content and educational collateral for the Canadian government’s Energy Innovators Initiative (NRCan) from within a health care framework as the Energy Efficiency Coordinator for the Canadian College of Health Services. Throughout that time, Kent created sector-specific initiatives related to environmental sustainability including National Health Care Energy Efficiency Awareness Week, Energy Perspectives, the sector’s first energy management newspaper, A Resource Guide for Energy Efficiency Awareness Champions, the CCHSE/OEE National Energy Management Award, and coordinated and assisted in the design, deployment and analysis of the first national research study to assess energy efficiency practices and awareness levels in the Canadian health services sector.

Samantha Putoš – Sustainable Health Care Programs

SamanthaSamantha Putoš is a recent graduate of a Master of Science and the newest addition to the team. Motivated by a growing concern for the wastefulness of scientific research, she co-authored an article entitled “Neglecting the Null: the pitfalls of under reporting negative results in preclinical research,” implicating poor reporting practices as one of the major sources of waste in translational medicine. After graduating she took a year off to complete a farming apprenticeship in Peachland, British Columbia and fulfill a long-standing ambition to travel the world. An avid SCUBA diver and hiker, her travels exposed her to many of the detrimental effects climate change and poor waste management are having on the Earth’s natural environments. Upon returning she was determined to refocus her career to combine both her interests in healthcare and sustainability.

Samantha is particularly interested in the relationship between small-scale agriculture and mediating greenhouse gas emissions and waste production. One of her goals is to see hospitals invest more in locally grown food and increase the nutritional quality of their meals. In her spare time she has a hard time sitting still and can be found cycling, running, swimming, rock climbing, playing squash, or attempting to make healthier versions of conventionally unhealthy treats.
