In France, the building sector (residential and commercial) represented 16% of carbon emissions in 2015 (use-phase). The building sector therefore has a major role to play in the carbon transition by acting on all available levers: sufficiency, efficiency, decarbonised energy and carbon sinks. How much can the sector contribute to the overall goal of carbon neutrality by 2050? The article presents findings from Transition(s) 2050, a set of scenarios developed for the whole economy by ADEME, the French Environmental Transition Agency. It focuses on sufficiency: which role can it play in the decarbonation of the building sector, both in the use-phase and beyond? What would enabling conditions be?
Sufficiency can contribute to achieve further energy savings compared to “efficiency-only” scenarios in areas such as domestic electrical appliances or space cooling, hence easing the wider decarbonation effort. Furthermore, sufficiency has systemic implications beyond the use-phase. It contributes to decreasing energy consumption in the industrial sector, as building less has direct impact on the demand for construction material. It also has impact on other resources such as land. Land take and building waste are significantly lower in the most sufficient scenarios. However, implementing sufficiency requires profound changes both in policies for the building sector and the way these policies are designed.
