A dynamic multi-stakeholder climate change social movement for climate action has formed that includes progressive institutional investors, business, civil society as well as with educators, students, youth and existing movements, such as the women’s, trade union, social justice, Indigenous and consumer protection movements. This bottom-up climate change social movement has played a critical role in building new partnerships and coalitions to create the political will for the Paris Climate Change Agreement and UN Sustainable Development Goals Agreement. This movement is now playing a critical role to provide bottom-up pressure on investors, businesses and governments to ensure the Paris Agreement and UN Sustainable Development Goals are prioritised and implemented. The chapter overviews the latest developments of this movement, and thereby provides an inspiring overview of how you and your business, organisation, government, or community group can partner and join existing cross-sectoral networks to share knowledge, and collectively take action to achieve the scale and speed of greenhouse gas emission reductions required.
