Policy durability is regularly identified as a critical ingredient in society’s response to the wicked policy challenge of climate change. Over the course of the last three decades, many climate and energy policies have been adopted. In fact, in Chapter 1 we noted that climate change probably constitutes one of the most active sub-areas of environmental policy making. However, we also noted another, more ‘inconvenient truth’ about climate governance: that a surprisingly large number of climate policies are not sufficiently durable or effective enough (van Renssen, 2018). Indeed, climate policy is widely regarded as being especially susceptible to weakening and reversal (Rosenbloom et al., 2019: 168), because it generally targets powerful vested interest groups and does not deliver immediate and visible policy benefits to voters.
