Policy4Rebuild – Reduction of embodied greenhouse gas emissions in building construction

Renovating existing buildings is a great way to reduce grey greenhouse gas emissions (GHGEs). However, despite net-zero targets, replacement new construction is often preferred to renovation. There is therefore a need for political and planning instruments (policies) that lead to a reduction in grey GHG by targeting the potential for savings in grey GHG through conversion instead of replacement construction. In a situation analysis, the reasons for preferring new construction to conversion are prepared in a stakeholder-specific manner using desk research and case studies. Based on this, various policy options are analyzed in terms of their impact mechanisms and feasibility, and policy packages are drafted. The situation and policy analysis is supported by a quantitative survey of affected stakeholders. The findings result in an impact- and implementation-oriented policy design and a policy brief for Swiss cities and cantons.
