1 Consistent calculation of multiple system models and improved integration of regionalized data Emilia Moreno Ruiz, Bo Weidema, Gregor Wernet CILCA 2013, Mendoza (Argentina)

2 The assets of v3 Data Providers Easier integration of your data in the database Easier maintenance Prepared for Regionalisation End Users Flexibility of choice: allocation, system expansion Automatic assembly of regionalised supply chains slide 2

3 The structure that makes this possible 1. Distinction between Activity and Product 2. Independent unlinked multi-output Unit Processes 3. Markets are also Unit Processes 4. Linking through the markets (geography) 5. Different algorythms for linking the activities into System Models slide 3

4 1. Distinction between Activity and Product An ecoinvent activity dataset represents a unit process of a human activity and its exchanges with the environment and with other human activities. slide 4

5 2. Independent unlinked multioutput Unit Processes slide 5

6 3. Markets are also Unit Processes Market activities represent the consumption mix of a product in a given geographical localisation. slide 6

7 4. Linking transforming datasets through the markets Linking happens through the markets, based on their geographical localisation. Unit Processes slide 7

15 5. Different algorythms for linking Different System Models ecoinvent v3 default System Model All activities supply the market (average suppliers). By-products are allocated. ecoinvent v3 consequential System Model Unconstrained (marginal) suppliers. By-products are treated by substitution (system expansion). slide 15

Different algorythms for linking Different System Models I1 I2 I3 Multi output transforming activity A B(by-product) Allocation relative to A (different allocation properties) Substitution relative to A I1* I2* I3* *A/(A+B) Single output transforming activity A I1 I2 I3 -B Single output transforming activity A slide 17
