"Nelson Forests supply chain was analysed from cradle to market using a carbon calculator
developed for Nelson Forests.
The calculator follows life cycle analysis (LCA) principles and methodologies from leading international standards. Results obtained include carbon emission profiles for log and lumber products produced by Nelson Forests, forest operations and their Kaituna Sawmill, delivered to domestic and export customers."

While the data in this report is primarily based upon the Nelson operations, the same types of conclusions can be reached for the industry as a whole.
The research creates a number of questions and equally answers a number of critics. The major findings were as follows -
• It is just as efficient to ship timber products to Australia as it is to truck them from Nelson to Christchurch
• Distribution can account for up to 80 percent of the emissions of lumber from cradle to market
• Generation of heat energy for kilns can account for up to 85 percent of the greenhouse gas emissions for mill operations
• Reductions of 16-25 percent of carbon emissions can be achieved across the log and lumber supply chains. (Source: NZ Wood, 2009)
