Many targets call for “universal access” (e.g. to infrastructure) or “zero” deprivation (e.g. extreme poverty, hunger). For each such target, the technical communities and member states will need to define the precise quantitative standard for their commitment to “universal access” or “zero” deprivation. In most cases these standards will indeed be 100 percent or 0 percent, respectively, but there may be areas where it is technically impossible to achieve 100 percent access or 0 percent deprivation. In such cases countries should aim to get as close as possible to 100 percent or 0 percent, respectively.
