On the day after the Opposition Day Debate on the expansion of Heathrow, Theresa Villiers and Greg Clark took part in a live webchat on the environment and climate change.
They answered questions submitted via Twitter, email and live messaging on topics such as the introduction of a smart grid, how to make train travel more affordable, Conservative opposition to the third runway at Heathrow, and the potential for electric cars.
The event was hosted by Dr Keith Allott, Head of Climate Change at WWF – and you can watch it back below.
Greg served as Director of Policy for the Conservative Party under three successive Leaders before being elected to Parliament in 2005.
