The Cancun Agreements, adopted at the 2010 United Nations Climate Change Conference (COP16) in Cancun, Mexico, represented a significant, albeit incremental, step forward in international climate negotiations. A critical component of these agreements was the commitment to provide financial resources to developing countries to support their efforts in mitigating and adapting to climate change. This financial aspect, often referred to as “Cancun Agreement Finance,” encompassed both short-term and long-term pledges, aiming to facilitate a transition to low-emission development pathways and enhance resilience to climate impacts.
A cornerstone of the Cancun Agreement finance framework was the commitment by developed countries to provide “new and additional” resources, approaching $30 billion in “fast-start finance” for the period 2010-2012. This aimed to provide immediate support to developing countries, particularly the most vulnerable, to address their urgent climate change needs. The fast-start finance was intended to be balanced between mitigation and adaptation and was to be transparently reported by developed countries. While the fast-start finance initiative contributed to numerous projects and programs globally, concerns remained regarding the additionality of the funds and the effectiveness of their disbursement.
Beyond the fast-start finance, the Cancun Agreements formalized a long-term goal of mobilizing $100 billion per year by 2020 from a variety of sources, including public and private, bilateral and multilateral, and innovative sources. This commitment was intended to enable developing countries to implement more ambitious mitigation and adaptation actions. The Green Climate Fund (GCF) was established as a key mechanism for channeling a significant portion of this long-term finance. The GCF is designed to support projects and programs that promote low-emission and climate-resilient development in developing countries. The Agreement also stipulated the establishment of a Standing Committee on Finance to assist the COP with respect to the Financial Mechanism of the Convention, improving coherence and coordination in the delivery of climate finance.
Despite the commitments outlined in the Cancun Agreements, challenges persist in the operationalization and fulfillment of the financial pledges. The definition of “new and additional” remains a point of contention, with some developing countries arguing that a significant portion of the finance provided consists of re-labeled Overseas Development Assistance (ODA). Furthermore, the transparency and predictability of climate finance flows continue to be areas of concern. The methodologies for tracking and reporting climate finance vary, making it difficult to accurately assess the extent to which developed countries are meeting their commitments.
The journey to achieving the $100 billion goal proved complex and protracted. While developed countries have increased their climate finance contributions over time, the target was not consistently met by the initial 2020 deadline. Estimates and methodologies also vary, leading to disagreements about the exact amount of finance delivered. Moreover, concerns persist regarding the balance between mitigation and adaptation finance, with adaptation often receiving a smaller share compared to mitigation efforts. Future climate negotiations will need to address these outstanding issues and ensure that climate finance is adequate, predictable, transparent, and accessible to developing countries to effectively tackle the challenges posed by climate change.
