 Smart cities require efficient and emission-free transportation for both people and goods. Studies have focused primarily on passenger transportation, but freight transportation has also seen significant growth during the COVID-19 pandemic. This paper examines how logistics service providers, LSPs, can help facilitate the transition to energy, efficient smart cities. It proposes a new IEEE matrix to classify innovations applied by LSPs in sustainable urban freight SUF. These include urban freight consolidation and or transshipment, consumer as a service provider, CAASP, and choice of transportation modes. The paper also introduces the concept of CAASP, which involves customers taking over some transport operations with the use of smart technologies, thereby reducing energy demand. The paper analyzes smart technologies, internet of things, big data, artificial intelligence, digital twins, that enable energy efficiency by reducing fuel consumption in SUF. Finally, it proposes a new IEEE matrix as an actionable tool for the classification of innovations applied by LSPs in SUF, according to the level of their interconnectivity and energy efficiency.
