Introduction by Jacquetta Lee, Director of the Practitioner Doctorate Programme in Sustainability, U. Surrey

Stefan Pauliuk is post-doctoral fellow, Industrial Ecology Programme, NTNU

[Stefan Pauliuk]

Need to transform

  • What do we need to scale up, moving from unsustainable to more sustainable?

Adopt a transformation approach, but need to model a different scale

  • Combining three approachs is called prospective (forward-looking) assessment of transformation strategies

DI_20150708 030913 ISIE plenary StefanPauliuk SystemsApproach

Prospective modeling adds modeling principles rather than specific methods

Trace back to Dan Muller [Department of Energy and Process Engineering, NTNU]

  • Trace concrete and timber

Then Hatayama, Daigo, Matsuno, Adachi (2010)

Updated to Milford, Pauliuk, 2014

  • Scale up model to global scale, find mitigation potential

Similar work by Liu, Band and Muller 2012 on aluminum, can go down to alloy

  • Lovik Moderesi and Muller 2014

Eishkaki and Graedel 2013 JCP, looking at critical materials, may find some supply constraints

Busch, Steinberger Dawson 2014: conflict between low carbon and circular economy

Northey, Mohr, Mudd 2014 RCT:  How could existing copper resources be mined in the future

I/O-based techniques back to Leontieff and Duchin 1986 Future Impact of Automation

  • De Konging Huppes Tukker 2015

Supply curve approach:  Nakamura, Kondo, Kagawa 2014 MaTrace

LCA:  Hertwich, Gibon, Bouman 2015 PNAS:  Take energy supply from scenarios and improvements, what is the impact in future?

Prospective modelling in IE builds on MFA I/O and attributional LCA

  • Differentiate between LCA and prospective modeling
  • Expectations high, so believe the direction could be scenario analysis to model transformation of society’s metabolism is suitable

Two scopes:  with IE, and beyond

  • Assess bundles of mitigation and adaptation strategies
  • Trend:  convergence of methods, more consistent data, better reproducibility of results

DI_20150708 032048 ISIE plenary StefanPauliuk connect

Connect to other fields?

  • IE is considered small, need to link to energy system models, climate models, prospective economic models, land use and coverage models
  • Integrated assessment modelling
