Plans for a third runway at Heathrow Airport were thrown into doubt on Thursday, after a court ruling said that the expansion was unlawful.

Jasmine Whitbread, chief executive of business group London First, told Wake Up to Money that while the ruling was disappointing, it doesn't mean this is the end.

"They have said the future of the third runway can go ahead if it can fit in with the UK's climate policies, so on one hand what we've got here is a government decision on Heathrow with a big parlimentary majority and a decision to go ahead, and on the other hand there, climate policy, and the two just have to be married up," she said.

It might sound hard to reduce emissions if you're building an extra runway to allow more planes to take off and land, but Ms Whitbread thinks this isn't an impossible task.

"The truth is that Heathrow has been at the forefront of working with the aviation industry to get to the next zero emissions by 2015 in line with the Paris accords, so we want the UK to be a leading actor in de-carbonisation," she said.

"Those airlines know they're going to have to change in order to be successful."
