A conceptual framework outlining factors affecting the acceptance of earth as a sustainable building material in the United Kingdom

Despite the fact that contemporary earth construction may open up new avenues to cutting down CO₂ emissions, a review of literature reveals that there is sparse research to date identifying reasons behind why there may be resistance to earth construction as a sustainable construction material in the United Kingdom. The aim of this paper is to formulate a conceptual framework that facilitates a clearer understanding of factors affecting the acceptance of earth as a sustainable material in the UK. To achieve this aim, this study adopted a research methodological framework comprising of an extensive review of literature, the Delphi technique, and in-depth interviews. The conceptual framework provides insight into factors related to the UK context specifically including a lack of technological innovation, resources, well-established supply chain networks, training facilities in universities and building codes. These issues may be addressed through the promotion of earthen architecture as a method of cutting CO₂ emissions and introducing earth construction modules in relevant degree programs.
