State of the Nationally Determined Contributions: Enhancing Adaptation Ambition

1. Introduction

Nationally determined contributions (NDCs) are an integral part of the Paris Agreement and communicate voluntary actions by countries to mitigate and adapt to the effects of climate change. Though the NDCs focus on domestic mitigation measures, the Paris Agreement created an opportunity for countries to include adaptation in their NDCs as an important contribution to global action on climate change. Parties to the Paris Agreement commit to a five-year NDC enhancement cycle (Article 4.9), with the expectation that they can adjust their NDCs at any time to enhance the level of ambition (Article 4.11). The 26th Conference of the Parties (COP26) in Glasgow urged Parties that had not yet communicated new or updated NDCs in advance of COP27 to revisit and strengthen the 2030 targets by the end of 2022 and develop a work program on ambition and implementation. The COP also requested that the United Nations Framework Convention on Climate Change (UNFCCC) secretariat prepare an annual NDC synthesis report.

This paper assesses whether and how adaptation ambition increased between the first and updated submissions for 86 countries that had updated their NDCs by end of June 2021. The updated NDCs represent the second round of NDC submissions from the analyzed countries and comprise both updated first and second NDCs submitted to the UNFCCC. Nine of these 86 countries had also submitted their national adaptation plans (NAPs), which were also analyzed. Given the June cutoff date, this paper does not include an assessment of all submitted first or updated NDCs; however, a more complete data set of adaptation information from all updated NDCs is available online in the Climate Watch NDC data platform by the World Resources Institute (WRI).

This paper seeks to contribute to other analyses of NDCs, most of which have focused on countries’ mitigation targets. Examples of such analyses have focused on a subset of NDCs (Patel et al. 2020) or on issues such as gender (CARE 2020b; IUCN 2021), have analyzed implementation and support requests (NDC Partnership 2020b), or have considered adaptation as an element of a more comprehensive analysis with adaptation and mitigation elements (NDC Partnership and Vivid Economics 2021). The UNFCCC has produced a summary report of all NDCs, which has an adaptation section (UNFCCC 2021a), and other analyses of adaptation ambition in the NDCs are forthcoming (Patwardhan et al. forthcoming).

To assess enhanced ambition of the adaptation components of NDCs, the authors created an analytical framework based on existing WRI work, including Adapt Now, the flagship report of the Global Commission on Adaptation (Bapna et al. 2019), other WRI research on enhancing NDCs (Fransen et al. 2019), and on transformative adaptation (Carter et al. 2021). The framework enables assessment of whether and how adaptation ambition was enhanced in the latest round of NDC submissions, how adaptation actions map across key action areas, and how losses and damages from climate change are reflected in the NDCs as well as instances of transformative adaptation. The findings of the paper reflect broad trends in adaptation rather than a country-specific analysis of the NDCs.

Assessing Adaptation Ambition in NDCs

Climate change impacts are felt forcefully around the world, and new reports (e.g., IPCC 2021) indicate that these impacts will only intensify; thus, adaptation becomes a clearer and more urgent requirement for countries. Raising ambition on adaptation and reflecting this in NDCs, which can both represent the summation of existing strategies and form the basis for subsequent national plans and processes, indicates how seriously countries are taking the adaptation imperative (NDC Partnership and Vivid Economics 2021; Patwardhan et al. forthcoming).

Increasing ambition in adaptation implies that a country is doing more to adapt, such as by increasing investments, improving protection against climate impacts, widening the scope and coverage of adaptation actions, and improving adaptation implementation and delivery. This improves countries’ adaptive capacities and reduces negative impacts on people living in the country, particularly the most vulnerable. Adaptation ambition is necessary to protect the most vulnerable, who have contributed the least to causing climate change, and to clarify the adaptation needs to the international community.

Based on a literature review, consultations with peers, and an initial review of NDC documents, the authors identified nine elements that form the basis of the framework used to analyze increased adaptation ambition in the NDCs. Details on the development of this methodological approach can be found in Appendix A. The elements are as follows:

  • Are there increasing efforts to ensure ownership of the NDC document? Are political engagements and consultations more extensive during its development?
  • Does the adaptation component of the NDC clarify how it aligns with other international, national, subnational, and sectoral adaptation efforts?
  • Does the NDC use the latest information on climate change impacts, risks, and vulnerabilities? Does it make use of information such as the latest national communications or studies conducted to develop other adaptation plans, such as the NAP?
  • Do the prioritized adaptation actions cover critical systems, such as food and nutrition security, water, and nature-based solutions?
  • Do the prioritized adaptation actions include targets, indicators, baselines, and costs to ensure they are ready for implementation?
  • Does the NDC identify how adaptation actions will be monitored and evaluated and how progress of their implementation will be tracked?
  • Are there increased commitments to equity and inclusion as indicated by references to the integration of gender, inclusion of indigenous voices, and of local knowledge?
  • Are issues related to losses and damages from climate change impacts and their links to the adaptation component of the NDC well articulated?
  • Is there evidence of thinking related to transformative adaptation actions, with a focus on changing underlying systems to increase resilience?

Assessing increases in adaptation ambition, however, is not straightforward; adaptation is context specific and intertwined with the country’s development trajectory. It is dependent on, among other things, the nature of climate hazards, national and subnational institutions, social norms, capacities and constraints, and the availability of financing. Adaptation also lacks standard metrics for assessing success or increases in ambition, although efforts are being made, including through the Sharm el-Sheikh work program on the Global Goal on Adaptation (UNFCCC 2021c).

Section 2 of this paper describes the framework the authors used for this assessment. The findings, in Section 3 and synthesized in Section 4, highlight the broad trends in each of these categories that contribute to assessing ambition. These findings underpin the reflections in Section 5 that are identified for three different audiences: country governments, bilateral and multilateral donors, and the UNFCCC.
