Abstract: The Transport Decarbonisation Index (TDI) is a novel indicator-based diagnostic toolkit designed to help low- and middle-income countries benchmark their surface transport systems’ readiness for sustainability and decarbonisation. The TDI employs 30 indicators, classified into eight dimensions covering sustainable, low-carbon transport. The dimensions were identified using a four-phase approach. Through pilot testing in 12 countries across Sub-Saharan Africa and South Asia, the TDI benchmarks transport performance, enabling policymakers to prioritise actions to reduce emissions and enhance transport sustainability. While the pilot countries scored relatively well based on the defined ranges and thresholds on indicators such as per capita transport greenhouse gas emissions and finance, they performed less well on public transport availability and electrification. The pilot phase revealed significant gaps for African countries in freight transport activity data and highlighted the need for improved data collection. Additionally, several metrics, including equity and informal transport, were not readily available. The TDI can be a valuable tool for benchmarking performance and informing policy decisions by offering a nuanced understanding of key transport dimensions and policy options. Although the TDI provides insights for policymaking, it is not a standalone solution and requires further analysis and stakeholder engagement for effective implementation.
