I agree that we should be taking action to mitigate climate change.1 Switching to a plant-based diet, which can save up to 0.8 tonnes of CO2 per year, is certainly one of these interventions. But this is not an easy change for everybody to make, and we need to be prepared to lead by example, making our own lifestyle changes alongside those we expect of patients. For example, I do not think we should give up so easily when it comes to cutting down our own emissions from airplane flights: 1 hour of flying is equivalent to around 0.25 tonnes of CO2 per passenger (www.carbonindependent.org/22.html). Although medics are fortunate enough to have opportunities to attend international conferences, this does not entitle us to write off the option of cutting down on flying to reduce our carbon emissions. There are other options to consider, for example, broadcasting conferences over the internet or holding conferences in places that are easily accessible by rail or other more sustainable forms of transport.
We also need to take care about how to broach the subject of lifestyle change. As with any health promotion message involving lifestyle change, there is a fine line between encouraging and empowering patients and making them feel overwhelmed with an impossible task. An environmentally friendly diet may be easy for some to achieve but very difficult for others if they have limited financial resources or other psychosocial stressors taking up their attention and time. We need to use our best consultation skills and assess the possibility of lifestyle change within each individual’s life situation. Discussing more manageable possibilities, for example, having a meatless day as suggested in Storz’s article, could be an essential step.1
