Retrofit poverty: Socioeconomic spatial disparities iretrofit subsidies uptake

Framed in the concept of distributional justice, retrofit poverty may be understood as the inequality of opportunity to improve the energy performance of the home. Retrofitting existing homes may have substantial carbon-mitigation and cost-saving potential. Retrofit subsidies may increase energy improvement activities, raise awareness and lever market offers. However, there is concern about inequitable outcomes. This quantitative study used publicly available data sets to explore the socioeconomic and spatial distribution of the outputs of a market-based, white certificate programme for residential energy-efficiency improvements in the state of Victoria, Australia, between 2009 and 2017. Certificates signified avoided carbon emissions as a proxy for energy cost savings. Regression analyses combined data of certificate generation with socioeconomic indices, dwelling numbers and tenure characteristics at the postcode level. Areas with lower economic resources and higher shares of rented dwellings were statistically significantly associated with lower certificate generation intensity. As low-income households and renters feature highly in metrics of energy stress, the uneven distribution of benefits suggests that a utilitarian distributive subsidy approach may be regressive and (re)produce energy inequalities. A better understanding of the contexts, compositions and mechanisms that characterise retrofits is needed to develop socially equalising and effective policy tools. Web Portal Ubiquity Press.
