Yes, I know I promised to file a blog on eco-towns a fortnight ago. However, I have to confess I was tempted into moonlighting it away to the Telegraph, who are running a series of stories on what they are calling ‘Gordon’s poll tax’. So, for an update on the impressive number of campaigns that have emerged to oppose the fifteen shortlisted eco-town sites, you’ll have to read my [...]

My favourite word today is ‘emblazoned’. That’s what adverts for cars will have to be from now on - emblazoned with details of fuel consumption and CO2 emissions, thanks to a sudden change in advertising rules by the government.

The 4x4 campaign has been working on this for about a year now, but the endgame was surprisingly easy, with the Department for Transport changing its guidelines for advertising [...]

After all the election excitement, I’ve been enjoying some glorious (if skint) ‘resting’ time over the past few weeks, getting some fresh air in the Lake District and having long lunches with everyone I’ve not seen in months.

Last week, I went to a preview screening of a new film about climate change called ‘The Age of Stupid’. Part sci-fi, part impressive documentary, this is a much more interesting [...]

So, the election in London is over, we’ve lost a great Mayor, gained an uncertain future and kept our two Green Assembly Members in the face of an almighty squeeze. After a week of catching up on sleep, meeting the babies my friends produced during the campaign and – importantly – reacquainting myself with the local pub, it’s time to reflect.

Although as predicted I am not Mayor, the Greens [...]

Okay, I’m going to be painfully honest and admit I have a very slim chance of becoming Mayor of London after the ballots are counted on 2 May. I’m being asked why I’m standing a lot at the moment, and the truth is it’s not because I think I’m actually going to be Mayor.

But, I do believe in giving voters a full choice of candidates in every election, [...]

The Guardian scored a bit of a coup this week, with three candidates for Mayor – including me - getting out their laptops over the weekend to take part in what can only be described as a stonking row on the Comment is Free website. It all started when Ken Livingstone published a piece pointing out the uncanny similarities between Boris Johnson and Brian Paddick in the [...]

Today I announced my recommendation for a "Sian 1, Ken 2" vote for Mayor of London this year, and here I want to explain why.

I’ll start by making it clear that Ken Livingstone is not my first choice for Mayor of London. I am my first choice for Mayor of London - more than anything London needs a real Green Mayor. But voters in this election do have two [...]

Last Monday I helped to launch the Fair Pay Network, a new coalition of anti-poverty and workers’ rights campaigners, of which I am now a proud patron.

At the launch in Westminster were fellow patron John Cruddas MP and the chair of the Fair Pay Network, Karen Buck MP, as well as representatives from network members NUS, Unite, UNISON, the Fawcett Society, and Oxfam. Not forgetting campaigners from [...]

It was always going to cause a stir. The new emissions-based Congestion Charge (the 'CO2 Charge') was confirmed by Ken Livingstone at a press conference at City Hall last week. I was there to witness him signing the order to bring in the new scheme, which means that, from 27 October, the most polluting band G cars (emitting more than 225 grams of carbon dioxide per kilometre) will pay £25 [...]

Conference in Reading is remarkably quiet compared with recent Green Party get-togethers, or perhaps it just seems that way after leaving behind the excitement of the London election. The campaign is snowballing now, and the first full hustings took place on Thursday, hosted by the Green Alliance. You can watch the videos and judge for yourself how we all did on Friction.tv.

Away in Reading, we've been enjoying [...]
