The total road freight volume of toxic substances in the UK is forecasted to decline from 104.9 million tonne kilometers in 2024 to 102.78 million tonne kilometers by 2028. This reflects a steady annual decrease. The year-on-year variation shows a consistent decline, with an approximate annual decrease of around 0.49%. In 2023, this figure stood somewhat higher, indicating a downward trend over the forecast period.

Key future trends to watch include:

Enhanced regulations around the transport of toxic substances, potentially driving further reductions in freight volume.
Shifts in production and consumption patterns that may impact the need for hazardous material transport.
Technological advancements in alternative materials or transport methods that can alter volume needs.
