The scale of the climate change challenge…

Average UK emissions per person per year currently10 tonnes CO2 equivalentneeds to be reduced to 2 tonnes CO2 equivalent

•80% emissions reduction in the UK by 2050•34% per cent emissions reduction by 2020 •All new buildings to be zero carbon by 2020

Tackling the issue at home

Housing accounted for around 30% of all the UK's carbon dioxide emissions in 2004 (40 million tonnes of carbon)

13% of all rubbish produced45% of all public water

Space heating - 60.51% Water heating - 25.23% Appliances and lighting - 13.15% Cooking - 2.74%

Zero carbon new homes by 2016

Tackling the issue at home – new build

25% improvement in the energy/carbon performance in 2010 (vs. 2006)

44% improvement in 2013

Zero carbon requirement in 2016

= Code Levels 3, 4 and 6

Tackling the issue at home – retrofitting existing stock

Up to 7 million British households to benefit from eco upgrades by 2020

Up to 65,000 jobs in the green home industry To insulate 6 million homes by the end of 2011 To have insulated all practical lofts and cavity walls by 2015

PAYS scheme

New set of standards for workmanship and products to protect consumers
