Agri-Food Sector, 1-4 Oct 2012
Table 1. Overview of emission sources within the covered system boundaries
Greenhouse
Name
Feed mixtures and
material for bedding of
stables (own production)
730
gasses Description
CO2 and N2O Diesel is taken into account within energy consumption.
Production and transport of fertilisers, pesticides en lime.
Impact of fertilisers and the use of lime (direct and indirect) and the
impact of crop residues are taken into account according to the
IPCC method (Tier 2 calculation).
CO2 and N2O Farming, transport, processing en land conversion is taken into
account in de covered emission factors.
CH4 The IPCC method is applied (Tier 2 calculation).
Feed mixtures (purchased)
Animal (stomachintestine
fermentation)
Manure storage and
disposal
CH4 and N2O The IPCC method is applied (Tier 2 calculation).
Manure application CH4 and N2O Allocation between animal (40%) and vegetable production system
(not used for own feed
mixtures)
(60%) on the basis of nitrogen uptake by plants.
Energy and water consumption
1
CO2, CH4 and
N2O
Energy consumption (electricity; diesel; red diesel; gas)
Water consumption (tap and ground water)
Transport of goods CO2, CH4 and Assumptions are being made for the goods entering and leaving the
N2O farm.
Processing materials CO2, refrigerant
Use of cleansing products and refrigerants
1: water is not a source of emission; however the use of energy for processing and transporting tap water is
taken into account.
Table 2.Overview of the applied allocation method
Process Products Allocation method
Farming of crops Products for human consumption (like flower);
Products for animal consumption (like wheat starch)
Other products (like straw)
