It is, therefore, recommended that functional regulations and plans that favour land and housing affordability, energy consumption, the reduction of carbon dioxide emissions and the overall increase in productivity values through economies of scale and agglomeration be adopted. To scale up the measurement of this indicator, there is a need to provide capacity-building to NSOs and to make accessible the appropriate technology. This should include local authorities that are responsible for the preparation of urban plans, regulatory mechanisms and land control, and the need they have to prepare evidence-based plans and policies. Several Expert Group Meetings (EGMs) have been held to promote the harmonization of the different elements of the methodologies and input data.
