This report provides a strategic and analytical examination of transport decarbonisation across APEC economies, with a focus on electric vehicles (EVs) and fuel cell vehicles (FCVs). It emphasises that there is no single transition pathway, as outcomes depend on diverse domestic conditions such as infrastructure readiness, governance capacity, energy systems, and market structures. The report introduces an informed decision-making framework that highlights uncertainty, trade-offs, and the importance of timing and sequencing. It identifies key system pressures, including supply-chain risks, grid constraints, and urban limitations, and presents scenario-based approaches to support flexible policy choices. Rather than prescribing solutions, the report proposes an options-based approach to preserve adaptability, support regional learning, and enable economies to align short-term priorities with long-term sustainability goals.
