Nothing you can do really. If you feel as though your MP is not representing you then all you can do is vote for a different MP in the next election. If you feel very strongly about issues such as the environment then I suggest the Green Party. My personal opinion is that Conservative are only going 'green' because of the ongoing issue of global warming and so is a brilliant publicity stunt for their new, young and dynamic leader. (The last sentence should be read with sarcasm).
