    GHG Footprints

    Work led by Landcare Research, supported by Plant and Food Research, AgriLINK New Zealand, and Massey University, produced an indicative sector carbon footprint for ZESPRI ® GREEN, GOLD and ORGANIC Kiwifruit for Zespri International Ltd and the Ministry of Agriculture and Forestry.

    The first ISO-compliant, third-party peer reviewed Life Cycle Assessment (LCA) comparing the most common artificial Christmas tree to the most common real Christmas tree sold in the United States, found that the choice of either tree has a negligible impact on the environment.

    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. A range of on-orchard emissions has been reported for each crop and some scenarios looked at for transport of the crop.

    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 five-year project seeks to build capability among New Zealand manufacturing companies for product-oriented environmental management. LCM Champions in six case study companies are implementing Life Cycle Management, and are being upskilled and mentored through an LCM Training Programme. In addition, a Research Programme is evaluating the enablers and barriers for successful LCM implementation over the first two years of the project. For more information, click here.

    This study uses multi-regional input-output analysis combined with selected bottom-up analyses to estimate the greenhouse gas emissions embodied in New Zealand’s imports and exports. The analysis includes data for 113 countries and regions representing the entire world economy, with increased detail for New Zealand and Australia. Preliminary results indicate that emissions embodied in New Zealand’s imports are much lower than those in its exports. The study concludes in June 2010. For more information click here.

    Category: Transport

    This project uses Life Cycle Assessment methodology to estimate the benchmark energy use and greenhouse gas emissions (GHG) for passenger and freight transport using rail and roads in New Zealand.  In addition stormwater contaminant loading due to runoff from road and rail infrastructure will also be quantified. For more details contact the project leader.

    Category: Energy

    Life-cycle energy and global warming potentials of specific New Zealand wind farms have been assessed for Contact Energy and Trust Power. These assessments included production, transport, maintenance and disposal impacts over the wind farms’ lives. These studies assisted in Environment Court hearings, and with communication of environmental impacts of the wind farms.

    This paper describes the results and methodology used for determining the primary energy, carbon dioxide and greenhouse gas emission factors for New Zealand electricity and fuels.  The analysis is based on using life cycle analysis (LCA) methodology so consequently includes all upstream as well as in-use emissions.  The results have also been compared to the MED published in-use emissions.

    The Exemplar house is a basic two storey design of a house, with a building system typical for New Zealand comprising of three bedrooms and a garage. This model was used as the basis for a study on energy and climate change impacts of a standard house over its life cycle. Materials, heating schedules and climatic setting of the house were modified to examine effects on the life cycle impacts.
