This resource explains the concept of climate justice, the idea that equity and human rights must be central to climate action. It outlines how the causes and consequences of climate change are unequally distributed across countries, communities, and generations, highlighting the disproportionate impacts on women, Indigenous Peoples, people with disabilities, and those in low-income or highly vulnerable regions. The resource also explores obstacles to achieving climate justice, such as limited participation, unequal access to resources, and risks faced by environmental defenders, while showcasing global examples of progress supported by UNDP and other actors.
