Comparison of Three Production Scenarios for Buxus microphylla var. japonica ‘Green Beauty’ Marketed in a No. 3 Container on the West Coast Using Life Cycle Assessment
Ingram, D.L., Knight, J. (University of Kentucky), Hall, C.R. (Texas A&M)
The impact of west coast production scenarios for boxwood marketed in a #3 container on carbon footprint (CF; kilograms of carbon dioxide equivalents (kg CO2e)) and variable costs at the nursery gate for Scenario A (propagation to #1 to #3 container) was 2.198 kg CO2e with variable costs of $4.043. Scenario B (propagation to field to #3 container) was a CF of 1.717 kg CO2e with variable costs of $2.880 and take a year longer in production than the other two models. The CF of Scenario C (propagation to #1 to #2 to #3 containers) would be 3.364 kg CO2e with variable costs of $5.733. Containers, transplants/transplanting, irrigation, and fertilization accounted for the greatest portion of CF and variable costs in each scenario.

Carbon Footprint and Variable Costs of Production Components for a Container-grown Evergreen Shrub Using Life Cycle Assessment: An East Coast U.S. Model
Ingram, D.L. (University of Kentucky), Hall, C.R. (Texas A&M University), Knight, J. (University of Kentucky)
Production components of an evergreen shrub (Ilex crenata) grown in a #3 container in an east coast U.S. nursery are analyzed for their costs and contributions to carbon footprint (CF), including product impact in the landscape throughout its life. The propagation-to-landscape CF for an individual plant was 2.337 kg CO2e with variable costs from cutting-to-gate of $3.224. After accounting for carbon sequestered in the landscape by the plant, the plant’s CF drops to -1.445 kg CO2e. Major contributors to CF and costs are discussed. This information can communicate economic and environmental value of green industry products to the consuming public.

Comparison of Carbon Footprint and Variable Costs of Selected Nursery Production Systems for a 5-cm-caliper Red Maple
Ingram, D.L. (University of Kentucky) and Hall, C.R. (Texas A&M University)
The objective of this study was to examine the differences in global warming potential (GWP) and variable cost structure of a 5-cm-caliper red maple tree grown using two alternative production methods including a field [balled and burlapped (BNB)] production system and a containerized, pot-in-pot (PIP) production system. Findings indicate that the total system GWP and variable cost for the PIP tree system is -671.42 kg of carbon dioxide equivalent (CO2e) and $250.76, respectively, meaning that the tree sequesters much more carbon during its life than is emitted during its entire life cycle. In the BNB system, the GWP of the tree is -666.15 kg CO2e during its life cycle at a total variable cost of $236.13.
