This project describes the methodology used, results, and issues that arose in estimating the carbon footprint of the summerfruit supply chain for Summerfruit NZ. The analysis is based on using life cycle analysis (LCA) methodology so consequently includes all upstream emissions are included.
This project examined the greenhouse gas footprint of lamb produced in NZ and consumed in the UK. It used LCA and covered the full life cycle from cradle to grave (including consumption and waste). It was carried out with the Meat Industry Association and Beef and Lamb NZ and supported by MAF, Landcorp and Ballance.
This project determined, based on Life Cycle Assessment methodology, the total resource use and greenhouse gas emissions (GHG) or carbon footprint of milk solids produced by the Lincoln University Dairy Farm (LUDF). The system boundary is to the farm gate.The LUDF GHG emissions were found to be 11% lower on a production basis than the typical NZ dairy farm at 8,875 kgCO2e/t milksolids.
A literature review determined the default and upper and lower range of greenhouse gas (GHG) emissions (and primary energy) from greenwaste windrow commercial compost production, transport, and field emissions. Being LCA based the system boundary included a credit for avoided landfill CH4 emissions and a debit for forgone landfill carbon sequestration. These variables had the two biggest impacts. The results are being reviewed and so have not yet been made public.
