Decision pathways for road freight decarbonization
研究了公路货运系统脱碳的决策路径，通过五场研讨会识别障碍、推动因素和关键决策，发现多数问题涉及社会技术、政治和决策治理，而非单纯技术经济因素。
The road freight system is complex, with many system dependencies. These dependencies mean that individual actors are often unable to take radical decarbonization action alone, and system-level decisions are required. Decision dependencies mean decision pathways are needed specifying key decisions and decision sequencing. Five decision pathway workshops were held with mixed groups of industry actors, policymakers and experts. Decarbonization barriers, enablers and decisions were identified and dependencies between these specified. A new software tool “Pathplotter” was used to facilitate pathway definition and analysis, and workshop commentary was qualitatively analyzed using NVivo. It was found that it is possible for mixed actor groups to define decision pathways, and requirements to operationalize this approach are identified. While techno-economic factors remain important, most barriers, enablers and required decisions are found to be socio-technical, political or related to decision governance. This reinforces the need for more research into these understudied transition aspects.
