To limit global temperature increases to ‘well below 2 ºC’, it is necessary that current national commitments to reduce emissions are increased, and these commitments are implemented. The identification of local development benefits from climate change mitigation is a possible motivating factor to achieve this. However, there is a lack of practical examples of how climate change mitigation and development priorities can be integrated in national planning processes, particularly in low- and middle-income countries. This work considers two questions i) What are the factors that have to be considered when developing a plan integrating GHG reductions with local development goals?; and ii) How do you structure a process to reach a consensus about the plan itself?. It does this by conceptualising the integration of climate mitigation and development benefits as a policy intervention. As a case study, a national planning process that integrated climate change mitigation with improvements to air quality and human health in Nigeria is conceptualised, ex-post, as an intervention theory model. The key factors identified include the importance of tailoring the planning process to the national context of how development priorities are identified and then used in the allocation of national budgets. In particular, assessments undertaken within the planning process, of emission reductions, and development of implementation pathways provided necessary information on how climate mitigation actions contribute to national development priorities. Additionally, the importance of structuring these assessments within a planning processes that also engaged key stakeholders to allow the information produced by the assessments to be informed, and acted upon, by those responsible for mitigation in each key sector is also highlighted. Finally, approaches for the use of intervention theory as a conceptual framework to design a planning process, ex-ante, are discussed, to further optimise the integration of development priorities into climate change planning.

为了将全球温度升高限制在“远低于 2 ºC”，有必要增加当前的国家减排承诺，并落实这些承诺。确定当地发展从减缓气候变化中获益是实现这一目标的一个可能的推动因素。然而，缺乏关于如何将减缓气候变化和发展优先事项纳入国家规划进程的实际例子，特别是在低收入和中等收入国家。这项工作考虑了两个问题i) 在制定将温室气体减排与当地发展目标相结合的计划时，必须考虑哪些因素？和ii) 你如何构建一个过程来就计划本身达成共识？. 它通过将气候减缓和发展效益的整合概念化为政策干预来实现这一点。作为案例研究，在尼日利亚将减缓气候变化与改善空气质量和人类健康相结合的国家规划过程被概念化，事后，作为干预理论模型。确定的关键因素包括根据国家背景调整规划过程的重要性，即如何确定发展优先事项，然后将其用于分配国家预算。特别是，在规划过程中进行的减排评估和实施途径的制定提供了关于气候减缓行动如何促进国家发展优先事项的必要信息。此外，还强调了在规划过程中构建这些评估的重要性，该过程还让关键利益相关者参与进来，以使评估产生的信息能够被每个关键部门的缓解负责人告知并采取行动。最后，事前讨论，以进一步优化将发展优先事项纳入气候变化规划。
