In 2023, the national transport of empty road freight in the UK stood at a certain level (not specified in the provided data). Forecasts indicate a progressive decline over the next five years, starting from 1.18 billion vehicle-kilometers in 2024 and reaching 1.03 billion vehicle-kilometers by 2028. The year-on-year percentage variations show a continuous decrease, indicating a consistent downward trend.

Future trends to watch for:

Increased adoption of technology to optimize load planning and reduce the occurrence of empty runs.
Evolving regulations and policies aimed at minimizing environmental impact, which may further influence transport strategies.
Potential shifts in consumer behavior and logistics operations that could either mitigate or exacerbate the current trends.
