10:10

The 10:10 climate change campaign is the brainchild of Franny Armstrong (Director of 'The Age of Stupid' film) and was launched today in partnership with The Guardian. Ted Cullinan is one of many well-known individuals and organisations from the arts, sport, tv, politics, etc., to have joined the campaign. Ted joined them this afternoon for the official launch in the Tate Modern Turbine Hall.

The project aims to bring every sector of British society to work together to achieve a 10% cut in the UK's carbon emissions in 2010. Scientists now agree that global emissions must peak within the next five to ten years and then begin to fall. 10:10 believes that in order to give ourselves a chance, we need to act now. By cutting emissions by 10%, it provides an immediate action that is achievable for everyone. This is a brilliant first step towards the 85% cuts by 2050.

Ted designed and built his own passive-solar house in Camden in 1964, and this has recently been listed Grade II*. But buildings are currently responsible for 40% of UK emissions, so there is a lot for us architects to be doing. Our practice has been monitoring its footprint for just under two years and although originally aiming for a 5% reduction in utilities usage, we are now well on target for a 20% reduction, comparing 2009 against 2008 consumption.

On his return to the office Ted said of the inauguration that it was "brilliantly organised chaos".
