Over 500 leaders from around the world signed an open letter calling for the equitable representation of men and women at COP27, the 2022 UN Climate Conference in Egypt. This follows the low representation of women at prior climate conferences, with them making up only 37 percent of delegates and only receiving 29 percent of the speaking time. This article follows several of the leaders who supported the petition, including Farhana Yamin, an environmental lawyer who has been involved in international climate negotiations since 1991, and Bianca Pitt, the founder of the She Changes Climate Initiative. The article also highlights the contributions of young women and advocates from the Global South.
