We live in a world characterized by discontinuities, where thresholds for abrupt and irreversible change are omnipresent, both in economic and ecological dynamics. Such thresholds, often referred to as tipping points, trigger nonlinear responses on the part of individuals or ecosystems.Climate change is a prominent example of the pervasiveness of tipping points, since they appear both in the strategic decision to embark in costly mitigation (Heal and Kunreuther, 2012) and in the Earth's climate system (Lenton et al., 2008).In this chapter we will focus on "behavioral tipping points", to distinguish them from the ecological ones. As it will become apparent, though, the two are closely linked, since planetary boundaries define "the safe operating space for humanity with respect to the Earth system and are associated with the planet's biophysical subsystems or processes" (Rockström et al., 2009). Hence, to discuss strategies one has to account for the underlying physical processes and how they are perceived (Tavoni and Levin, 2014).Whether a country or a subnational actor (a city, an NGO or a firm) decides to invest in a clean technology, or more broadly in actions aimed at reducing greenhouse gas emissions,
