ABSTRACT
In architecture, and by extension, in 0 km conservation, materials can be manufactured, commercialised and sold in their area of production. 0 km conservation makes use of genuinely local material over global materials which often have no certificate of origin and whose composition is not clearly defined, simultaneously making savings in the product transport process and the pollution that this produces. In addition, as stated by David Morris (2007), buying and producing locally enables accountability, while distance disables accountability. This involves the defence of construction and local production, boosting the direct sale of these products from the small producer to the consumer or local builders and favouring the consumption of local materials and products in risk of dying out.
