Not Without Us follows seven grassroots activists from around the world to the 21st U.N. Climate Talks in Paris. The effects of climate change on their lives reveal what's at stake if a strong agreement to limit carbon emissions is not reached. Yet, the landmark Paris Accords, signed by 195 nations, is non-binding and fails to mention the main cause of global climate change: fossil fuels. Not Without Us connects the dots between the inability of the U.N. process to address climate change and Big Oil's control over governments, between the economic inequality and the oncoming climate disaster, and between a fossil fuel driven economy and the 1% who control it. Not Without Us demonstrates the importance of grassroots groups to empower mass movements to create systemic change.
