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.
