AIUI as part of the planning consent for T5 BAA have obligations to ensure
that specific proportions of people employed at the airport (not just BAA
employees) and of airline passengers access the airport by public
transport.

I reviewed the planning permission (SoS decision) and S.106 undertaking for
T5 some time ago. From memory, their obligation is to implement a Green
Travel Plan, approved by LB Hillingdon. From memory, as with most GTPs,
there are targets set for journeys to be undertaken by a particular mode.

Just because there are targets, that does not mean that there are penalties
for failing to meet those targets! But in this case, unlike some other
instances, I do not think there was one particular aspect, or the whole
operation that could not be undertaken if the targets were not met. If I'm
bored, I'll go back and have a look at the decision letter/legal agreement
one day. May well be blogged by one of the Heathrow NIMBY websites; I've
not looked.
