“…Contrary to most sustainability concepts, the basic idea here is to avoid defining sustainable development along 'classic' economic, ecological, and social lines. Instead, the IHSC begins with the constitutive elements of the sustainability overall concept, derived from key documents such as the Brundtland Report, the Rio Declaration, and Agenda 21: (a) the postulate of inter-and intragenerational justice, (b) the global perspective, and (c) the anthropocentric view [19][20][21][22], that are translated into three general goals: to secure human existence, maintain society's productive potential, and preserve society's options for development and action. These goals are further concretized by a set of sustainability rules, such as the satisfaction of basic needs, equal access to education and information, the ability to provide for oneself, the sustainable use of renewable and nonrenewable resources, an adequate development of human and knowledge capital, maintenance of social resources, or the preservation of cultural heritage and cultural diversity.…”
