US in focus

I feel that most of my reports have been about European issues from an European perspective. Today I want to spend some lines on the US development.

US essentially face the same challenge as Europe.The transport sector has increased the emissions of green house gases more than other sectors and is therefore in focus. For large and dens cities in particular, person transports by bus constitute an alternative to cars.

Even if buses already offer the most energy efficient and environmental friendly alternative, further effort is spent on improvement. There are three technology areas that can be realised in the immediate future to improve the efficiency further:

-Energy hybrid buses with break energy recuperation, where the US by no doubt is the leading market. Nova Bus, a Volvo Bus company, offers today a hybrid bus with good fuel saving figures.

-Bus infrastructure for capacity buses, with separate lanes, priority at traffic lights, advanced information system for passenger information and traffic control.

-Sustainable fuels that are compatible with existing fuel infrastructure and engine technologies

US is the worlds largest consumer of biofuels. As for all new fuels an intensive work is conducted to analyse and approve new standards.

BBC recently reported that US hopes that the worlds major economies will conclude a leaders declaration in the G8 summit in July.

From the environment and for buses this is an unreserved positive development that is expected to increase the pace of change even further.
