21 NordLCA Background Green house gases GHG (CO2e) Reduction of climate impact is highly prioritized Existing tools stand well alone but would gain of cross-linking Nordic countries have similar conditions

22 Done so far State of the art Workshop Road map Next steps Combine with LCC and BIM Seminar Helsinki 12 September A guidline on LCA - FORE - MELI - One Click LCA - EFFEKT climate module - Veg LCA - Gen. data road and rail - Klimatkalkyl - Geokalkyl - EKA

23 System boundaries

24 Standards

25 CO2, costs, time in 3D The City Rail Loop s link

26 Emission calculation and cost control based on data model

27 MIRIAM - ett nätverk Vejdirektoratet, VTI, Rijkswaterstaat, BRRC, UC Davis, IFSTTAR, AIT, ZAG, FEHRL, Trafikverket Cooee pavement x % reduction of GHG 27

28 Pavement characteristics rolling resistance energy losses 28

29 Methods Environmental factors: - temperature - tyre pressure - snow, ice, water Socioeconomic analysis RRC = MPD + X IRI Good enough? (Ulf Sandberg, VTI) 29

30 Transformativ Infrastructure a competition in innovation concepts How to build the Öresund bridge with zero emissions of GHG? 30 Åsa Lindgren, STA

31 The two team project I. The Challenge Change in paradigms II. New materials and Design and Nature as an innovator III. Cutting edge techniques and Urban transformation IV. Behind the zero emissions New possibilities for man and nature V. (Not decided but probably an international touch) The winner is presented during this summer. A pre-jury and a top-jury (CEO s, directors) 31

32 Not just a choice of materials. Upgrading of materials, reuse and recycle Sustainability perspective! Which life cycle? Procurement Digitalization Planning 32
