In 2023, the total road freight volume of substance emitting flammable gases with water in Germany was 3.87 thousand units. Forecasts indicate a steady decline from 2024 to 2028, with values dropping from 3.65 to 2.78 thousand units, marking a cumulative percentage decrease indicative of structural changes or efficiency advancements. The average annual decline over five years, or the compound annual growth rate (CAGR), reflects an ongoing downtrend likely amplified by regulatory or market shifts.

Future trends to watch:

Adoption of stricter environmental regulations impacting road freight volumes.
Influence of alternative transportation modes or technologies reducing traditional road freight demand.
Potential economic factors influencing demand for flammable gases that might shift volume trends.
