Beyond the role that government policy plays in advancing climate change education in public school systems, education networks play a critical role in supportingScaling and scalingEco-Schools (Foundation for Environmental Education, FEE)global scaling"- such efforts, particularly in an increasingly digitized and globally connected world. While government-supported, systems-wide reform depends on policy coherencePolicy coherence, support, and capacity which will be discussed Chap. 7 , much progress in climate education currently sits outside of formal government mandates. An example of this are the school-based cases that will be discussed in Chap. 5 , of which many are private school initiatives, and many among the rest reflect grassroot initiatives, unrelated to government mandates. The ‘World’s Best Schools Prizes’ that recognize such exemplary practices are a private initiative of the non governmental organizationT4Education T4EducationExemplary schoolsoften linked to networks and awards (e.g., T4Education). In this chapter, we examine initiatives where teachers experiment, learn from one another, and develop the professional capacity to build climate literacy among students which result from non-governmental initiatives. We will examine efforts of civil society involving networks of teachers and schools, some of them working within nations, and others across nations.
