Abstract
Climate action is not advancing quickly enough to prevent catastrophic harm. Understanding why might require looking at existing leadership structures and the inequitable gender representation therein. Critically examining dominant power structures could pave the way toward more comprehensive, innovative, and expedient environmental solutions-and we argue that elevating women's climate leadership is key to safeguarding planetary health. Women have historically been left out of climate science and governance leadership. Women are disproportionately impacted by the health effects of climate change, particularly in Indigenous and low- and middle-income settings. Therefore, our call for women's climate leadership is both an issue of justice and a matter of effectiveness, given evidence that inclusive leadership rooted in gender justice leads to more equitable outcomes. Here, we present evidence for why gender equity in climate leadership matters along with considerations for how to attain it across sectors and stakeholders.
