DESCRIPTION:'Absolute Zero: meeting the UK’s legal commitment to zero em
 issions in 30 years time.'\nIn her last days in office\, Theresa May chang
 ed the UK’s Climate Change Act in response to thsi years’ social prote
 sts\, from targeting an 80% cut in emissions from 1990 to 2050\, to a 100%
  cut\, or “net zero.”  The key question about how we achieve this lega
 l obligation (which is well-founded according to climate scientists) is wh
 ether we largely aim to develop new technologies that leave our lifestyles
  untouched\, or whether we start by modifying our lifestyle with today’s
  technologies\, knowing that later we’ll be able to benefit from new tec
 hnologies.  To date\, all national and international policy developments h
 ave favoured technology first\, and as a result global emissions are risin
 g and UK emissions are not falling as fast as predicted. Therefore this ta
 lk takes the opposite approach: what does zero emissions look like if we o
 nly use technologies that are mature today? How long will we then have to 
 wait for the restraint required to achieve zero emissions by 2050 is relie
 ved by new technologies - and which of them are most likely?  This talk wa
 lks a tightrope between the arts and the sciences: is climate mitigation f
 undamentally about innovation or is it about social choice?
