Developed under the High Volume Transport (HVT) programme funded by UK International Development through the Foreign, Commonwealth & Development Office (FCDO), the Transport Decarbonisation Index (TDI) initiative. This Methodology Report provides a comprehensive framework to assess and guide transport decarbonisation efforts, specifically tailored for low- and middle-income countries (LMICs) in Sub-Saharan Africa and South Asia.
The report offers detailed methodological insights into how the TDI evaluates a country’s readiness to achieve net-zero emissions in surface transport, empowering policymakers with clear, data-driven tools to guide sustainable transport transitions.
Key messages:
- A robust, transparent, and dynamic methodological framework is essential for accurately assessing transport decarbonisation readiness, allowing for iterative refinement based on stakeholder feedback and emerging best practices.
- The TDI’s multi-dimensional approach—covering passenger mobility, freight systems, vehicle emissions, governance, finance, and energy—enables comprehensive assessments that pinpoint targeted interventions.
- Practical, non-prescriptive policy recommendations derived from TDI scores provide actionable guidance tailored to specific national contexts, facilitating evidence-based decision-making.
- Strategies to address common data gaps—such as the use of proxy indicators, collaborative data collection, and regional databases—are crucial for maintaining accuracy and comparability across countries.
- Open access to the TDI spreadsheet toolkit allows policymakers and practitioners to independently conduct assessments, thereby fostering transparency, collaboration, and informed policy formulation.
