The adoption of the Paris Agreement in December 2015 moved the world a step closer to avoiding dangerous climate change. The aggregated individual intended nationally determined contributions (INDCs) are not yet sufficient to be consistent with the long-term goals of the agreement of 'holding the increase in global average temperature to well below 28C' and 'pursuing efforts' towards 1.58C. However, the Paris Agreement gives hope that this inconsistency can be resolved. We find that many of the contributions are conservative and in some cases may be overachieved. We also find that the preparation of the INDCs has advanced national climate policy-making, notably in developing countries. Moreover, provisions in the Paris Agreement require countries to regularly review, update and strengthen these actions. In addition, the significant number of non-state actions launched in recent years is not yet adequately captured in the INDCs. Finally, we discuss decarbonization, which has happened faster in some sectors than expected, giving hope that such a transition can also be accomplished in other sectors. Taken together, there is reason to be optimistic that eventually national action to reduce emissions will be more consistent with the agreed global temperature limits. Policy relevanceThe next step for the global response to climate change is not only implementation, but also strengthening, of the Paris Agreement. To this end, national governments must formulate and implement policies to meet their INDC pledges, and at the same time consider how to raise their level of ambition. For many developing countries, implementation and tougher targets will require financial, technological and other forms of support. The findings of this article are highly relevant for both national governments and support organizations in helping them to set their implementation priorities. Its findings also put existing INDCs in the context of the Paris Agreement's global goals, indicating the extent to which current national commitments need to be strengthened, and possible ways in which this could be done.

The transformational potential of Nationally Appropriate Mitigation Actions in Tanzania: assessing the concept's cultural legitimacy among stakeholders in the solar energy sector While energy-sector emissions remain the biggest source of climate change, many least-developed countries still invest in fossil-fuel development paths. These countries generally have high levels of fossil-fuel technology lock-in and low capacities to change, making the shift to sustainable energy difficult. Tanzania, a telling example, is projected to triple fossil-fuel power production in the next decade. This article assesses the potential to use internationally supported Nationally Appropriate Mitigation Actions (NAMAs) to develop solar energy in Tanzania and contribute to transformational change of the electricity supply system. By assessing the cultural legitimacy of NAMAs among key stakeholders in the solar energy sector, we analyse the conditions for successful uptake of the concept in (1) national political thought and institutional frameworks and (2) the solar energy niche. Interview data are analysed from a multi-level perspective on transition, focusing on its cultural dimension. Several framings undermining legitimacy are articulated, such as attaching low-actor credibility to responsible agencies and the concept's poor fit with political priorities. Actors that discern opportunities for NAMAs could, however, draw on a framing of high commensurability between experienced social needs and opportunities to use NAMAs to address them through climate-compatible development. This legitimises NAMAs and could challenge opposing framings.

Nearly all the world's governments have prepared and submitted their Nationally Determined Contributions (NDCs), setting out their climate pledges under the 2015 Paris Agreement. These NDCs are to be regularly updated, and many countries are expected to submit a new NDC in 2020. While several studies have assessed the content and potential impacts of the NDCs, this article focusses on the preparatory process and asks the question: under what conditions can countries be expected to develop NDCs that are sufficiently ambitious to contribute to fulfilling the Paris Agreement goals? For some countries, in particular developing nations and emerging economies, the process of preparing and implementing NDCs presents challenges in terms of political support; financial, human and technical resources; and analytical capabilities. With a view to improving future NDCs, this article provides insights from the first round of NDCs. Using results from four surveys carried out in 2015, 2017 and 2018 targeting government representatives and other stakeholders from primarily developing countries and emerging economies, the article finds that the NDC preparation process contributed positively to national climate policy processes. For example, it raised political awareness and preparedness for preparing and implementing climate policies across various ministries and agencies. It also prompted institutional innovation and more coordination between various policy areas. However, more can be done to enhance analytical capacity in order for countries to make commitments based on robust analysis and data.Key policy insights . In many countries, the preparation of the NDCs positively contributed to national climate policy processes by raising awareness and catalysing institutional change. . The NDC process improved political buy-in across government and nongovernment stakeholders thereby laying the foundation for future higher NDC and climate policy ambition. . A better understanding of broader impacts and the involvement of affected stakeholders in a targeted way could be conducive to reaching the goals defined in the Paris Agreement and support realistic, yet ambitious target setting. Conversely, process-related problems may lead to implementation problems. . More analytical, financial and technical resources are needed to implement the first round of NDCs and support countries in preparing future NDC cycles. ARTICLE HISTORY

To meet global climate policy goals, societies need to transform at scales unprecedented since the industrial revolution. In context of the 1992 UN Framework Convention on Climate Change, developing countries are asked to contribute to greenhouse gas control objectives by proposing so-called Nationally Appropriate Mitigation Actions (NAMAs).Although the concept provides developing countries with complete flexibility to design NAMAs, a majority of proposals seek international support. This paper improves our understanding of the matching of NAMA design and international support by exploring (miss-)alignment between support providers' and NAMA developers' prioritization for NAMAs. The article assesses survey responses from support providers in light of records of NAMAs. We conclude that there is a mismatch between support providers' primary emphasis on systems for measuring emissions reductions and the lack of such provisions in existing NAMA proposals. Furthermore, sector preferences may create structural biases in NAMA support.
