Raised prices for petrol and diesel are an important part of the government's environmental strategy.

The haulage companies have also not opposed a transition to more environmentally friendly fuels, but many find it difficult to keep up with the pace of the change.

- Since fuel is a major item in all hauliers' finances, these costs must be passed on to customers.

The hauliers cannot bear the environmental responsibility themselves, he says.
