NON-FOOD OPTIONS at FARM LEVEL Greenhouse Gas Accounting for Non-Food Options (A web-based approach of LCA modelling) Hannes Peter Schwaiger JOANNEUM RESEARCH Forschungsgesellschaft mbH 23 rd April 2008
ENFA - European Non-Food Agriculture, Final Meeting, April Overview Defined fuel chains WP Objectives Web based tool Some examples / results Methodology: LCA, GHG emissions
ENFA - European Non-Food Agriculture, Final Meeting, April WP 32 Objectives To identify 3 bio-chains for which LCA models are created (e.g. pellets, biodiesel, wood chips form SR systems) Produce a computer model for the selected chains Conversion of the model into a web-based file (asp files) Post the model on the internet as an user friendly interface
ENFA - European Non-Food Agriculture, Final Meeting, April According to ISO „Life Cycle Assessment“ Standard Methodology of IEA Bioenergy Task 38 „Greenhouse Gas Balances of Biomass and Bioenergy systems“ Recommendations of COST Action E9 „LCA of Forestry and Forest Products“ LCA- Methodology
ENFA - European Non-Food Agriculture, Final Meeting, April Global Warming Potential, Functional Unit Greenhouse effect: GHGs in CO 2 -equivalents (CO 2, CH 4, N 2 O, CF 4 ) Equivalent factors: CO 2 1 CH 4 23 N 2 O 296 All results refer to the functional unit of: g CO 2 equivalents / km

ENFA - European Non-Food Agriculture, Final Meeting, April ENFA – web-based approach All results are calculated using GEMIS and transferred to a database (MySQL) located on a server here at JR Database (MySQL) can be updated via web-interface The “Model” shows the results of GEMIS runs, the user defines the chains via drop-down lists in a “top down approach” Updating and extension with other datasets, fuels etc. is possible Possibility of changing input parameters in the “Model” to bring own data, but only for: Data which influence the results linearly and allow an easy recalculation
