Excerpt from the Introduction: Frontline communities—those who are disproportionately impacted by climate risks and the consequences of climate change—tend to face systemic social, political, and economic barriers that create and exacerbate vulnerable conditions. The members of the CLIMAS team, therefore, are committed to ensuring that our work includes these communities and that our research supports their efforts to reduce their climate risks and increase their long-term resilience. In order to follow through on this commitment we recognize that we must carefully confront a set of ethical issues and challenges that arise from doing research that relies on directly engaging with a spectrum of perspectives, knowledges, experiences, and histories. Therefore we have developed five ethical principles to guide our engaged research: transparency, representation, autonomy, reciprocity, and respect for diverse knowledges.³ For each of the principles we provide a brief description, a set of questions to help us align our work with the principle, and a set of potential actions to implement the principle in practice. Following our articulation of the five ethical principles we then describe how we strive to be change agents for making institutional progress to reduce barriers to the types of engaged research approaches we collectively believe are critical to having substantive impact on complex problems like climate change.
