What organization created an international standard in 1992?

The organization that created an international standard in 1992 is the United Nations. In that year, the United Nations held the Earth Summit in Rio de Janeiro, Brazil, which led to several significant international agreements concerning environmental sustainability. One of the most notable outcomes was the establishment of the Agenda 21, a comprehensive plan of action for sustainable development globally. This marked an important moment in international policy, as it set the framework for encouraging nations to develop environmentally responsible policies and practices, focusing on key issues such as climate change, biodiversity, and sustainable resource management. These efforts align with the UN's mission of fostering international cooperation to tackle global challenges.
