A busway scheme to cut congestion and carbon emissions has received the funding necessary to start construction.The Department for Transport has approved £78 million, or 90 per cent of the total funds needed, for the Luton Dunstable Busway.Designed to encourage people to get on public transport and use their cars less, the 12 kilometre busway will connect Houghton Regis, Dunstable and Luton.It will be run by the Bedfordshire County Council and Luton and will serve areas of growing housing and employment.Counsellor Roy Davis, Luton Borough Council's cabinet member for regeneration, said: "By giving people the option of travelling to work or going to the shops without the hassle of endless traffic jams or the expense of high fuel prices, we can make our roads safer and our environment cleaner."The busway has consistently proven to be the most cost-effective option on the table and this decision takes us a step closer to completion. Now we can get to work on building and delivering it."Getting people to leave their cars behind will help reduce the carbon emissions due to road transport, which in 2006 amounted to 120 million tonnes, or 22 per cent of the total emissions.
