The NDC ASPECTS project will provide inputs to the Global Stocktake under the Paris Agreement (PA) and support the potential revision of existing Nationally Determined Contributions (NDCs) of the PA’s parties, as well as development of new NDCs for the post 2030 period. The project will particularly focus on four sectoral systems that are highly relevant in terms of the greenhouse gas emissions they produce yet have thus far made only limited progress in decarbonization. To advance these transformations will require to understand and leverage the Eigenlogic of those systems and take into account specific transformation challenges. These sectors are transport & mobility (land-based transport and international aviation & shipping), emission intensive industries, buildings, and agriculture, forestry & land-use, including their supply by and interaction with the energy conversion sector. <br/>For each of those sectors we will undertake „Sectoral Conversation“ to co-create evidence-based narratives with sectoral experts and stakeholders drawing on the consortium’s extensive networks. These narratives can then be translated into global pathways informing the Global Stocktake as well as national pathways for strategically selected countries for each of the four sectors. As an input to the Sectoral Conversations we will systematically assess transformation challenges and opportunities (economic, technological, political/institutional, capacity and awareness), including taking into account experiences with the implementation of the first round of NDCs as well as model-based quantitative analyses. Additionally, we will identify ways and means to improve international governance to enable and facilitate sectoral transformations.
