Worldwide, efforts to mitigate climate change through reduction of greenhouse gas emissions are falling short of what is needed to meet ambitious international goals such as the Paris Agreement.1 Research estimating the health effects of mitigation (HEM) indicates that climate change mitigation activities could have substantial health co-benefits that partially or completely offset the economic costs of mitigation. Yet few HEM findings have been incorporated into cost estimates of mitigation activities, making the activities appear unacceptably expensive to policymakers.2 The authors of a recent commentary in Environmental Health Perspectives present guidelines for conducting and reporting HEM studies so that the results are comparable and responsive to stakeholder priorities and that health benefits are thus more often considered in cost estimates.3
