The analysis allows for the possibility that the maximum weight of lorries in the UK would be raised to 60 tonnes by 2050. and their maximum length to 25m.
However, the research paper says that in calculating its scenarios, no account was taken of the "infrastructural changes" needed to accommodate LHV fleets.
LHV pioneer Dick Denby is quick to stress his Eco-Link 25.25m trailer overcomes this problem. He says: "This could be important for some types, but Eco-Link was designed to move freely on any road where today's trucks can move."
The research paper also states that there is little data available on the cubic volume of freight moved by road; average payload on laden trips is normally measured solely in terms of weight.
Denby says this skews the statistics
because it can assume a trailer full crisps is running virtually empty.
"Both the railways and governments h measured all freight statistics by we alone and have not found a way to ref modern traffic," he continues. "However, biggest potential gain in emissions is the 'high cube' sector. Disappointin nervous ministers are slow to pluck the courage to even do trials.'
