Beyond good intentions, to urgent action: Former UNFCCC leaders take stock of thirty years of international climate change negotiations

The authors, who have all held senior positions in the United Nations Framework Convention on Climate Change (UNFCCC) secretariat, take critical stock of what has been achieved since the negotiations were launched 30 years ago in December 1990. The assessment is made against seven functions or roles of multilateral processes (e.g. developing international law, setting goals, and supporting developing countries), and based on clear-eyed expectations of what multilateralism can and cannot do in a world of sovereign states and powerful economic interests. The authors point to some important successes, but also serious shortcomings, particularly in terms of failure of governments to deliver on agreed goals, and inadequate action and coordination within the UN system. The authors conclude that continuing at the pace of the last 30 years is unthinkable.Key policy insights The international climate change negotiations have successfully delivered three landmark treaties, providing the basis for a coherent international response to the climate crisis, but their impact is constrained by the realities of the multilateral system.Particular successes include the climate treaties’ goals – especially the UNFCCC’s ultimate objective and Paris Agreement’s temperature rise thresholds and ‘global net zero’ target – systems for data sharing and transparency and growing engagement of stakeholders.The principal shortcoming is failure by governments to fully implement treaty obligations, exacerbated by the still inadequate response of the business community. The rate of global emission growth over the 30-year period testifies to this failure, with the levels of support to developing countries also falling short of what is required.The principal role of the multilateral climate change negotiations must now be to promote full implementation of agreed commitments and ensuing national actions. Maximum use should be made of every mandated deadline. International agreement on clear and precise targets for 2030 and 2050 will be important, but only if accompanied by strong and specific policies.‘Business as usual’ in climate change negotiations will mean failure to avoid dangerous climate change. Fuller engagement by leaders is crucial to ensuring an all-of-government approach. The UNFCCC process should address its unwieldiness and act in line with the urgency of the issue.
