Health systems must modify their procedures and reduce their carbon emissions in order to address the climate crisis' effects on human health. For these institutions to change, health services and policy (HSPR) is necessary. We describe an effort by HSPR trainees from throughout Canada to develop ideas for changing health systems to be more ecologically responsible. We describe how HSPR must integrate environmental sustainability. We propose that this process must include a justice-based framework and that HSPR curricula, conduct, and content must take into account both human and environmental health [1]. Furthermore, financing sources and awarding bodies will be used to support these endeavours. We then provide trainees with suggestions for moving forward so that environmental sustainability is ingrained in HSPR.
