(1) Background and issues

    The transport sector represents today 23% of all energy-related global emissions and curbing these sectoral emissions is essential to implement global pathways consistent with the “well below 2C” climate goal of the Paris Agreement. The analysis of sectoral transformations implied by current NDCs shows that the transport sector is one of those where the ambition is particularly insufficient in the light of the requirements of md-century Paris-compatible transformations.

    Ambitious reductions of transport emissions require an alignment of national plans, global sectoral roadmaps and strategies of the private sector. Emission cuts will come from an in-depth assessment of country-specific technological, social and economic drivers of mobility and emissions.

    Sectoral roadmaps, investigating the potential evolution of these drivers in a collective low-emission context, should serve as a guide to the evolution of the boundary conditions of the national analysis at a global sectoral level. And extensive engagement with stakeholders and experts of the sector, notably companies active in the sector, is a key necessary condition for the definition of relevant and implementable emissions objectives and associated strategies.

    (2) Objectives

    This project aims at applying the methodological principles developed in the DDPP to the analysis of decarbonization pathways in the transport sector. Key methodological principles shared with the broader DDPP approach include: country-scale analysis grounded on the specificities of national circumstances, long-term analysis with a 2050 horizon to inform short-term decisions, transparency and granularity of the assumptions and results to enable knowledge sharing and facilitate conversation with different groups of stakeholders.
     
    Applied to the transport sector, this project aims to develop analyses of the decarbonization of the sector encompassing all levers of transformations. Beyond the conventional focus on technological improvements, this means developing a systemic analysis of all determinants of transformations of the transport sector, including the evolutions of behaviors, lifestyles, infrastructures and spatial organization.
     
    The analysis will aim to reveal the concrete consequences of these transformations on key indicators characterizing mobility patterns like modal shares, time spent, distance and budget dedicated to this activity. These studies are built to support engagement with sectoral experts and decisionmakers on the levers that are actionable for policy actions towards transport emissions reductions in their local context.
     

    (3) Transport Decarbonization Toolbox

    Since COP23 in Bonn and the Movin'On Summit 2018 in Montreal, DDP-Transport is working in cooperation with 4 other key international initiatives to inform policymakers on specific aspects related to the sustainable transformation of the transport sector:
    • Decarbonising Transport initiative led by ITF-OECD
    • Science Based Targets led by WWF, WRI, CDP and UNGC,
    • Sustainable Urban Mobility led by WBCSD
    • Global Macro Roadmap for Transport Decarbonization led by PPMC
    • Deep Decarbonization Pathways led by IDDRI

    These initiatives provide tools within the Transport Decarbonization Toolbox to support:

    • implementation and provide relevant inputs to develop short-term climate action plans for transport, increase the transport climate ambition for countries, cities and companies and inform the revision of Nationally Determined Contributions (NDCs);
    • multi-stakeholder dialogues between Countries, Cities, Companies and Citizens to enhance the future ambition.
