Maryland and Delaware have experienced the effects of climate change; it has become clear that libraries are critical to community resilience. Climate action can be overwhelming and sometimes debilitating when the solutions seem out of your control. In this session, leaders from the award-winning Sustainable Libraries Certification Program from the Sustainable Libraries Initiative will demonstrate how the program can bring about organizational transformation. They will provide examples from different library settings where leaders used replicable steps to conserve natural resources and ecosystems, that also help with social and economic development of their local communities.
