• The scale of the climate change challenge

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

Average UK emissions per person per year
currently 10 tonnes CO2 equivalent needs to be
reduced to 2 tonnes CO2 equivalent

• 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
produced 45 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

• 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 More information
to homeowners and housing associations
