Next week, thousands of participants from governments, the private sector, non governmental organizations, and other stakeholders will gather in Brazil at a United Nations (UN) summit to secure political and economic commitments for sustainable development and to address new and emerging challenges. These objectives recall the 1992 UN Conference on Environment and Development, also held in Rio de Janeiro. Although political progress toward these goals has stagnated, in the intervening 20 years science and technology have moved on.
The US submission on elements of the post-2015 agreement is a good basis for further deliberation by countries, as it is exhaustive with only some elements needing to be debated for a global consensus.
