Elizabeth Arend and Sonia Lowman examine four funds—climate funds and non-climate funds—to draw out lessons for gender integration in global finance mechanisms. As the international community mobilizes in response to global climatic changes, climate funds must ensure the equitable and effective allocation of funds for the world’s most vulnerable populations. Women and girls, disproportionately vulnerable to negative climate change impacts in developing countries, have largely been excluded from climate change finance policies and programmes. They must not only be included in adaptive and mitigative activities, but also recognized as agents of change who are essential to the success of climate change interventions.
