Environment by dfsiopmhy6



In our Environmental Report published in
March 2002 we set a series of objectives for
the next phase of our environmental strategy.
During this year we have made good progress
against these objectives.

We set out to:

Measure performance – Across the Group we have
implemented a standardised procedure for collecting
UK environmental data. As a consequence, all depots
and large stations in the UK now collect and report
data which will be used to benchmark as we seek to
set quantified reduction targets. Environmental data
collected includes:
● greenhouse gas emissions – use of fuel and

   energy by our fleet and sites together with
   refrigerant usage;
● water consumption;

● waste generation and disposal;

● incidents and prosecutions; and

● complaints.

Review the benefits of adopting a formalised
environmental management system – During the
year we successfully achieved certification to ISO
14001 at two Maintrain depots: Neville Hill in
Leeds and Soho in Birmingham. We are continuing
to evaluate the benefits of adopting an established
environmental management system as we do not
consider existing frameworks are suitable for all
our businesses.

Assess and provide the necessary training to
facilitate, encourage and empower managers
to implement the strategy – A series of training
courses were undertaken for staff responsible
for environmental matters at all levels in the
organisation. These included briefings to senior
managers in subsidiary companies and two-day
“train the trainer” courses on environmental
management for site managers.

Review objectives and targets for improvements in
our environmental performance – An Environmental
Steering Committee was formed during the
year. This committee has reviewed our Group
environmental policy and approved the objectives
and targets for 2003.

If 850,000 company car drivers did not receive free fuel
and therefore did not travel 6,000 miles a year then CO2
comparable to the total emissions of the city of Newcastle
would be saved each year.

If one million company car drivers used the train for 50% of
their business mileage instead of a single occupancy car
then CO2 comparable to half the annual total from a power
station would be saved.

regularly review fuel efficiency in all our operations.
It is difficult to set absolute targets for reducing
the emissions of greenhouse gases from our diesel


fleet for a range of reasons:
● Modern vehicles meet the latest standards and

    produce collectively lower emissions (of carbon
    monoxide, hydrocarbons, nitrogen oxides and
    particulates) but often at the expense of fuel
● Retro-fitting pollution abatement technology to

    older vehicles reduces the emission of pollutants
    but increases the consumption of fuel.
● The use of low-sulphur fuels improves the quality

    of exhaust emissions directly and also enables
    pollution-abatement technologies to operate
    effectively. Low-sulphur fuels are less efficient.
● New low-floor buses and coaches increase

    accessibility but are heavier than older vehicles,
    which again impacts on fuel efficiency.
● Modern climate control (better heating and

    air conditioning) also decrease fuel efficiency of
    our fleet.
