Brighton, UK, low-carbon treats
10:10 has coordinated events, from the large and iconic to small practical actions, across the globe. I'll be keeping track of some of them through the day today.

Wow, there is less than two weeks to go before 10:10:10 and there is so much going on all around the world. Here's an update on some of the things going on in the name of 10:10 Global over the past week. Deep breath....
The Daily Express and the Lighter Later crusade
When the Prime Minister speaks on an issue it carries weight, but the response to his speech yesterday on tourism and clock change has been phenomenal. Mr. Cameron has promised he and the government would consider the aims of Lighter Later - to realign UK clocks to better suit daylight hours - but first we have to show him that the people of the UK want change.

Lighter Later is now firmly on the radar of David Cameron. The prime minister today said it is up to us to tell him we want more sunshine in our evenings and promised he and his government "certainly will look at it".

Flash forward six months and 10:10 is now quartered in what what I can only describe as the best looking office in the city. So how did that happen?
10:10's Lighter Later campaign held a day of high-profile activity on Monday, the summer solstice, including a specially organised conference for MPs, peers and policy makers in Portcullis House, Westminster.

Today is the summer solstice – the longest day of the year. And for 10:10 it’s the day we take our Lighter Later campaign to the next level.
Roll over the image above to see how the Lighter Later campaign’s proposal – to move the clocks forward by one hour would help us make better use of the available daylight this summer. This timekeeping regime is known as Single Double Summer Time or SDST. Yes, we find that name confusing too!
Schools up and down the country have been doing some amazing work as part of their 10:10 commitment. Recently the Guardian profiled some great work by Argyle primary school. Not to be outdone, a year 9 class (with one year 10 interloper) from Barking Abbey School in Barking, East London, have put the finishing touches on what I can only describe as an incredible video telling us all to "Just Cut It".
