“…For example, whilst the Green Deal, introduced in 2013, used a market-led approach to stimulate the private sector to design and deliver retrofit options , it failed to attract private investors or households in large numbers (Bergman & Foxon, 2020;Mallaburn & Eyre, 2014;Rosenow & Eyre, 2016). Analyses of the failures of previous initiatives suggest the following factors need to be considered in future policy approaches: first, greater integration of expertise from multiple sectors and disciplines is needed (Rosenow & Eyre, 2016;Sibilla & Kurul, 2020); second, the behaviours and motivations of a wide range of actors need to be better understood and addressed (Bobrova et al, 2021;Gram-Hanssen, 2014;Murtagh et al, 2020); and third, there are likely to be unintended consequences of policies intended to improve energy efficiency of the housing stock (Davies & Oreszczyn, 2012;Shrubsole et al, 2014), including the possibility of creating or widening social injustices (Sovacool, Lipson, et al, 2019;Sovacool, Martiskainen, et al, 2019).…”
