The document summarizes Agenda 21, a non-binding action plan adopted by the UN in 1992 related to sustainable development. It includes 40 chapters organized into 4 sections covering social and economic issues, conservation, strengthening major groups, and implementation. The goal is to help the environment and was agreed at the 1992 Earth Summit. It calls for governments, UN agencies, and other groups to take action globally, nationally and locally toward sustainable development. While progress has been uneven, the UN has reaffirmed commitment to Agenda 21 over subsequent years.
