In response to environmental challenges, policymakers and other actors draw from a basket of well-worn tools, unfortunately yielding a suite of unintended consequences and larger systemic effects that counteract global sustainability. In this talk, I will introduce the notion of relational values (preferences, principles and virtues about human relationships involving nature), and show how these values can guide the implementation of these sustainability tools and their better integration in 'smart mixes' to leverage the structural and societal changes needed for sustainability.
