The National Safety Council approximates the entire losses owing to traffic accidents in 2011 was about $250 billion. There were somewhere in the region of 3 trillion vehicle miles, and 1.7 people per vehicle, so all this protection cost of cars comes to 4.6 cents a passenger mile (as it turns out is more than twice more normal approximations). By means of this 4.6 cent number, a rail line that shifts 780,000 drivers produces an additional $9 million a year of passage safety advantage.

A standard estimation is that cars produce 5 cents of blockage damage for each one vehicle mile of travel. From the same basis, let us factor in another 3 cents per vehicle mile to cover up neighborhood pollution, fuel dependence problems and road maintenance. This works out to another $9 million worth of benefits from decreasing the amount of drivers by 780,000 (the carbon impacts of High Speed 2).

Merging reduced carbon emissions, concentrated congestion and decreased traffic mortality offers an further $22 million worth of paybacks per annum from the rail line, which raises the $100 million advantage minus in service costs figure to $127 million, which is still much less than the $700 million anticipated cost per annum of constructing and sustaining the road and rail network. The ecological and mortality benefits of rail are genuine, but the enormity of the community benefits from swapping modes seems is rather small compared to the price of the organization (Department for Transport. 2009).

The Campaign for Better Transport press release intended for Greengauge 21's "The Carbon Impacts of High Speed 2" testimony confirmed that HS2 could bring superior carbon reductions by "sensible harmonizing policy measures and by employing full use of the capability that HS2 will discharge on the present railway" (GreenGauge21, 2011).

It may be important to look at the 'vital factors' for 'superior carbon reductions' declared by CBT.

Critical factor 1: The electrical energy employed to

At the national stage, the quantity of greenhouse gases from transport would be dependent on the full amount of quantity of transport created in the economy, not just the precise emissions per kilometer. HS2 is a method proposed to augment longer distance travel; on HS2 Ltd.'s approximation, one- fifth of all traffic would be latest journeys. How is that attuned with an intention of dropping carbon emissions?
The report also avoided the subject of non-greenhouse gas pollutants, and the environment of the electricity producing capacity employed to run HS2. If HS2 energy were produced in nuclear plants that might not be carbon-free and there might be non-carbon contaminants (such as nuclear byproducts, which necessitate treatment and long-term storeroom).

Critical factor 2: innovative development is focused around the stations plied by HS2, fostering use of public transport, on foot and cycling

It is hard to see how centering growth around HS2 stations would have much outcome at the countrywide level. In the present edition of HS2 Ltd.'s Y network, there are just nine stations, plying just four cities directly.
