Completing the Trip: Establishing a Global Quantified Climate Goal for the Transport Sector
This expert note proposes a global climate target for transport decarbonization and transition away from fossil fuels in the sector. A system approach is needed to transition the sector, and the target captures this pathway through vehicle electrification; prioritization of public transport, rail and active mobility; and scaling up sustainable fuels, particularly for aviation and shipping. A global transport target creates a shared understanding of what the world must do to deliver for the transport sector.

Countries should collectively commit to a quantified goal for transitioning away from fossil fuels in the transport sector. We propose a sectoral target of a shift to 35 percent green fuels and a 25 percent reduction in transport energy consumption (compared to 2022) by 2035. Such a goal encompasses all transport modes and embodies a comprehensive approach that includes a range of technologies, among them electrification, shifts to more sustainable travel such as rail and public transport, and scaling sustainable fuels for aviation and maritime.
At the 28th Conference of the Parties (COP28) in December 2023, the first global stocktake (GST)—sought to track progress toward the Paris Agreement’s goals and inform enhanced climate action—calling for countries to transition away from fossil fuels across all sectors. Further, it asked countries to accelerate emission reductions in road transport through a range of pathways. Although the GST identified some quantified goals, such as tripling renewable energy capacity and doubling the rate of energy efficiency by 2030, it did not establish a quantified transport target. This expert note explores the analysis from the International Energy Agency for developing a global quantified goal for the transport sector. The proposed transport goal stitches together existing sub-sectoral agreements and should be agreed on by countries, particularly by transport and related ministries, to inform climate commitments and Nationally Determined Contributions, or NDCs.
