Sustainable development ensures meeting the needs of the present generations without compromising the development opportunities for future generations, e.g. through integrated activities in the field of economic, social and environmental development. This kind of understanding of the sustainable development concept has been disseminated by the report Our Common Future of Brundtland Commission, formally known as the World Commission on Environment and Development. The concept was further developed at the Earth Summit in 1992, which resulted in an adoption of the Agenda 21 document. The next milestone for sustainable development was the United Nations Millennium Declaration which defined the Millennium Development Goals. Their implementation was expected to effectively meet the challenges of the twenty-first century by the target date of 2015. The conclusions of the Earth Summit held in 1992 were renewed in 2002 in Johannesburg, and then at the summit in Rio de Janeiro in 2012, known as Rio +20 (The Future We Want declaration). In 2015 the Millennium Development Goals were replaced by Sustainable Development Goals contained in Transforming our world: the 2030 Agenda for Sustainable Development.
Sustainable development is closely linked to the concept of green economy and such initiatives as Beyond GDP and Stiglitz Report.
