This methodological report proposes a framework to track global progress toward the 2035 targets established in the Ministerial Declaration “Towards Resilient and Low-Emissions Transport Systems for People, Development and the Planet”, namely, a 25% reduction in transport energy demand and a shift of at least one-third of energy use to sustainable biofuels and renewables. It addresses key measurement challenges, including differences between primary, final, and useful energy accounting, and the critical role of electrification in achieving the targets. The report is intended for policymakers, researchers, and technical experts tasked with monitoring transport energy consumption and tracking progress under this global effort. Readers will gain a practical, science-based methodology that can inform international accountability and climate monitoring processes, using the IEA World Energy Balances as the core data source.
