Nothing less than a systemic transformation of our societies, our economies, and our world will suffice to solve the climate crisis and close the ever-increasing inequality gap. After over 20 years of stunted and ineffective action to reduce climate pollution by governments – particularly in wealthy countries that have failed to meet their legal and moral responsibilities – only urgent and transformative and systemic change that can address the root causes of the crisis and deliver what is needed to keep global temperature rise below 1.5 degrees Celsius, the limit beyond which climate impacts will become potentially catastrophic. The urgency to keep temperatures down is not just about the planet and the environment. It is about people, and our capacity as humanity to secure safe and dignified lives for all. As social movements, environmental non-governmental organizations, trade unions and other civil society organizations with deep roots in communities around the world struggling to cope with the climate crisis, we take hope from the fact that while the scale of the challenge is enormous, people already have solutions and alternatives that work at the scale we need. From decentralized community-owned renewable energy for mitigation, poverty reduction and sustainable development, to agro-ecological methods for adaptation, there already exists a wealth of proven ideas and experience from which to build a global transformation – and it is booming.
