Modelling degrowth policies is essential to explore possible pathways to achieve wellbeing for all within planetary boundaries. Whilst the targets of simulation models might be similar across countries, the implementation of the resulting policies in different contexts raises fundamental questions around justice. For instance, while models may emphasise efficiency or environmental metrics, community stakeholders may prioritise local cultural heritage, different housing tenures and aspirations, or might face context-specific obstacles and trade-offs (e.g., between reducing housing size and increase in rent).
In our work, we apply a Swiss housing transition model to the context of the UK. The model focuses on housing sufficiency, shared spaces, wellbeing, and strategies to reverse urban sprawl. We subsequently compare results across key metrics, including land and built space use, empty homes, final energy consumption, greenhouse gas emissions, and biodiversity impacts. Based on these results, we move beyond the proposed metrics to reflect on the extent to which justice is addressed, both in the model and in proposed policy implementation, across countries. Raised questions include, for instance, differences in socio-economic structures (for example, the level of centralisation in governance), housing policies (for example, the role of cooperatives), and cultural norms.
The presentation will invite a discussion on a possible justice-centred degrowth framework that connects theoretical modeling indicators with actionable policy considerations - addressing barriers such as community dynamics, emotional ties to homes, and economic challenges of relocation, as well as exploring participatory governance tools such as citizen assemblies. Eventually, we hope that our session will help engage in a global dialogue on justice in sustainable housing.
