No, running a bus on methane means that CO2 is emitted from the

I never said it was

No, some ****wit from LT on R4 this week was trying to claim it was.

There is no methane involved. There are no carbon emissions. Only
water. You do not have your facts correct.

But the Usernet pedants will still insist water is an 'emission' - thus
missing the point entirely


But others rightly point out that production of Hydrogen (by BOC for
instance) is a very "dirty" process, thus hitting the nail on the head. All
LT are doing is moving the problem; they are doing nothing for the
environment.

Two points:

1. Hydrogen production is not necessarily a 'very "dirty" process'.
However, at it worst, it is no worse than the production of diesel or
petrol.

2. Once produced, there is no secondary pollution as there would be from
internal combustion engines.

So, pollution is reduced to one source, instead of thousands, where,
potentially, better anti-pollution systems can be used. And London's
streets and low-level atmosphere are no longer subjected to harmful
emissions.

So, by any measure, TfL have reduced harmful emissions.
