‘Some lessons and barriers’

‘Beyond Zero carbon Housing’ Symposium 24th Oct 2012 at University of Nottingham

• Behaviour first (Halve the demand….)• UK only responds to regulation (or a fiscal incentive?)• Moving from the individual to the collective• Knowledge transfer needs a revolution• but it’s the existing stock that’s the real problem• but it’s the existing stock that’s the real problem

Halve the demand,double the efficiency,halve the carbon in the

supply……supply……

OPM Review of Low Carbon Communities for DECC 7/12:

• demonstrated the huge potential of community groups

• included a range of organisations from well established to new • included a range of organisations from well established to new

who needed a model to follow

• Sharing knowledge is good but trips to London and DECC’s e-

portal poor (cf CABE shared learning programmes)

• schools are key to spreading the word especially into minority

ethnic communities

‘The single most important message is

the way it (the Transition Town) brings

people together in a community…’

years ago (thanks to David Birkbeck)

• 80% of the homes we will be living in in 2050 already exist

• Climate Change Act 2011 – 34% reduction by 2020 + 80% by 2050

• Our homes are responsible for 40% carbon (and other) emissions

• So how will you reduce your footprint by 80%?
