The Earth Summit in Rio de Janeiro, officially known as the United Nations Conference on Environment and Development (UNCED) held in 1992, led to the establishment of the United Nations Framework Convention on Climate Change (UNFCCC). One of its outcomes was the agreement to record a benchmark of global greenhouse gas (GHG) emissions at the 1990 level, which was a significant step towards addressing climate change by providing a reference point for measuring future emissions reductions.
