Freight transport has undergone similar changes, increasing in volume and shifting from railways onto the road. In 1953 89 billion tonne kilometres of goods were moved, with rail accounting for 42%, road 36% and water 22%. By 2010 the volume of freight moved had more than doubled to 222 billion tonne kilometres, of which 9% was moved by rail, 19% by water, 5% by pipeline and 68% by road. Despite the growth in tonne kilometres, the environmental external costs of trucks and lorries in the UK have reportedly decreased. Between 1990 and 2000, there has been a move to heavier goods vehicles due to major changes in the haulage industry including a shift in sales to larger articulated vehicles. A larger than average fleet turnover has ensured a swift introduction of new and cleaner vehicles in the UK.
