Medical news service Audiomedica have just released a 10:10-themed edition of their regular podcast, featuring 10:10 health coordinator Tim Nicholson.

Signing up the old-fashioned way

Here at 10:10 we're definitely partial to a good milestone, but this has got to be my favourite so far. On Monday we found out that  10:10 has shot past the 100,000 signups mark, thanks to a lady named Sandra Antonovic. 

At this point you're probably wondering a) who this Sandra person is and b) why the counter on the website seems to be stuck on 85,000 or so. Bear with me – this gets a bit strange.

From lightweight wine bottles to leaner website code, we've seen lots of imaginative 10:10 actions recently. Often, however, the biggest savings can come from tackling the basics.

Take Penryn College down in Cornwall, for example. By combining a student-led switch off campaign with improved lighting, heating and IT, the've managed to cut their energy usage by 16% this year. Run the numbers and this gives you a yearly cost saving of more than £50,000. Simple but effective.

What do you do when the low-hanging environmental fruit has already been picked and you’re still hunting for more reductions? Chris Oswick, Facilities Director at Colliers International faced exactly this dilemma:

There’s lots to be said about climate change. But more importantly, there’s lots to be done.

It could be a line from a 10:10 press release, couldn't it? In fact, it's the philosophy behind conservation charity BTCV's carbon army – a practical, hands-on response to the challenge of reducing emissions.

Series: six months in

We've spent the last few weeks badgering 10:10 businesses and organisations for info on how they've been cutting their carbon, so it's only fair that we spill the beans on our own 10:10 progress. Here goes...

Those crafty folk at the Guardian have done it again. A long-time backer of the campaign, the paper marked our six month anniversary with a special edition of the G2 supplement and an avalanche of new coverage on the website.

I was really glad to see these stories focus on the concrete actions people and organisation have taken to reduce their emissions. Signing up is great, but 10:10 is ultimately about doing, and the imagination and ambition 10:10ers have shown in making their carbon cuts is really inspiring.

It's happening.

After months of campaigning and lobbying MPs, we can finally confirm that there will be a bill in Parliament backing Lighter Later – our campaign to advance the clocks by one hour for lighter evenings.

Castle Point MP Rebecca Harris' bill would force the government to implement the time change if a full review of the evidence confirms the benefits.
