In essence, sustainable development is a process of change in which the use of resources, the flow of investment, the direction of technical innovation and the design of institutions are geared to increasing the ability of all people, now and in the future, to satisfy their needs and achieve their goals in life" (Brundtland Report 1987 Chapter 2 Paragraph 15).
"A strategy for sustainable development [...] must take economic and ecological criteria into account in its decision-making processes. Ultimately, they are part of the activities of lived reality. This requires changes in attitudes, objectives and organizational structures at all levels". (Brundtland Report 1987 Chapter 2 Paragraph 72)
In 2015, the Brundtland understanding of sustainable development was translated into the 17 UN Sustainability Development Goals (SDGs) with their 169 sub-goals and 230 indicators. All social groups and all nations are called upon to work together to make their implementation a success.
