Following the Paper Trail: The Impact of Magazine and Dimensional Lumber Production on Greenhouse Gas Emissions
Canfor, The Home Depot, Stora Enso, NA and Time Inc. commissioned the greenhouse gas life-cycle analysis (LCA) of two magazine chains and a dimensional lumber chain. The Heinz Center for Science, Economics and the Environment, an environmental non- governmental organization, helped the participants identify and address relevant environmental challenges.
The pie chart below represents a study conducted by The John Heniz Center that measure CO 2 -equivalents in the life cycle of two major magazine publications. As indicated by the chart, most of the CO 2 -eq emitted was in the form of mill emissions.

The LCA included all major direct and indirect carbon and GHG emissions from activities including harvest, transportation or wood and other raw materials to the mills, manufacturing, transportation of finished products to end user, recovery and recycling of products, and disposal of waste. The classification of direct and indirect emissions was done using standard protocols (WRI/WBCSD 2001).
