I'm not sure where on the Friends of the Earth website you can check which candidates have signed up to the pledge, 'though I've found the bit which records how many letters each local candidate has been sent. (I've had six, the Tory has had nine).
Anyway, for the record, I signed up to three out of four of the pledges, and gave the other one half a thumbs up. (That was the one on a 42% cut in emissions by 2020. Ed Miliband has said that signing up to a new agreement would mean increasing our current commitment to cut emissions by 34% by 2020, and it would have been easy for me to go along with the 42%, but I'm just not sure it's deliverable and didn't want to make an empty promise. But in theory, yes, we need to up our targets and be more ambitious).
My most enthusiastic response was, as you might expect, for the "Fix the Food Chain" pledge, about livestock's impact on the environment. I may not be one of the 277 MPs who signed the Early Day Motion on this (because I couldn't, not being a backbencher), but I think I'm still the only MP to have called a debate on the topic in the Commons.
