The integration of climate policy concerns in other policy areas where decisions are taken that determine greenhouse gas emissions is a prerequisite for effectively mitigating climate change. There are particularly strong interlinkages between energy and climate policy as the major part of greenhouse gas emissions is related to energy supply and use. We compile a set of five output‐focused indicators for assessing climate policy integration (political commitment, functional overlap, policy instruments, weighting, and time perspective). We then apply the criteria for an appraisal of climate policy integration in European Union (EU) energy policy during the last decade; that is, we focus on climate policy integration from a horizontal perspective. The focus of our research lies on the comparison of the Renewable Energy and the Energy Efficiency Directives of the Energy Union Package with their predecessors. Our results show that climate change mitigation is a key objective in these documents. The energy policy objectives are generally synergetic with climate policy. The Energy Union Package makes progress in some areas like the more stringent EU targets for renewable energy and energy efficiency or the more stringent sustainability criteria for biofuels. However, some conflicting issues arise. The shift from national to an overall EU renewables target and the change towards more market‐oriented support schemes might together with the elimination of preferential grid access for renewable electricity entail negative impacts on renewable investment and on achieving emission reductions. It remains to be seen whether the adaptations in EU energy policy will lead to the required acceleration of the energy transition.

欧盟的能源效率和可再生能源政策中是否存在气候政策整合？是的，不，也许

将气候政策关注点整合到其他决定温室气体排放的决策领域是有效缓解气候变化的前提。能源与气候政策之间存在特别紧密的联系，因为温室气体排放的主要部分与能源供应和使用有关。我们编制了一套以产出为中心的五个指标，用于评估气候政策的整合（政治承诺，职能重叠，政策手段，权重和时间观点）。然后，我们将标准用于评估过去十年中欧盟（EU）能源政策中的气候政策整合；也就是说，我们从横向的角度关注气候政策的整合。我们的研究重点是将可再生能源和能源联盟一揽子计划的能效指令与其之前的产品进行比较。我们的结果表明，缓解气候变化是这些文件的主要目标。能源政策目标通常与气候政策具有协同作用。能源联盟一揽子计划在某些领域取得了进展，例如欧盟对可再生能源和能源效率的目标更加严格，或者对生物燃料的可持续性标准更加严格。但是，会出现一些矛盾的问题。从国家可再生能源目标转向总体欧盟可再生能源目标，以及转向更加以市场为导向的支持计划，这可能与取消可再生能源电力的优惠电网准入制度一起，对可再生能源投资和实现减排产生负面影响。
