What is an LA 21?

At an international level, the Agenda 21 is a plan promoted by the United Nations for sustainable development in the 21^st century, approved by 173 governments at the Earth Summit held in Río de Janeiro in 1992.

The so-called Local Agenda 21s originated as a direct result of the Río Summit and, in Europe, they gained momentum after the well-known Aalborg Charter, signed in the Danish city of Aalborg in 1994 during the European Conference on Sustainable Towns and Cities. In the charter, the local entities give their commitment to preparing and implementing Local Agenda 21s, in order to promote sustainability at a local level.

Since then, the Local Agenda 21s have become a planning benchmark for achieving the sustainable development objectives stated at Río and Aalborg. The aim of the LA 21s is to promote measures directed at achieving a clean, just, habitable, fertile and humane world.
