The Handbook of Multi-Level Climate Actions emphasizes the need for significant climate action by every capable person on the planet at multiple levels of human experience and society. This includes individuals/households, formal and informal groups, organizations/communities, from local to global, and all levels of businesses, governments, and nonprofit organizations. It highlights the many ways that our species can meet the climate crisis and how entities at every level of human experience are, could be, and should be developing and implementing climate solutions, including those advancing energy efficiency, renewable energy utilization, and nature’s ability to sequester carbon. Nearly two dozen knowledgeable, caring, and active authors, representing both academics and practitioners, from multiple countries and disciplines, have risen to the challenge of attempting to motivate as many people as possible to take whatever actions they can as urgently as possible, to ensure that future generations of both humans and non-humans on this planet will have a sustainable climate that meets their on-going needs. This Handbook is an important work for scholars and practitioners working in the realm of environmental and climate issues, sustainability and CSR. It provides a comprehensive exploration of the current global situation, while also inspiring immediate action and forward thinking.
