Carbon footprint of flowering trees

Summary:
Researchers determined economic costs of component horticultural systems while conducting a life cycle assessment of field-grown 'Forest Pansy'. They also measured the sensitivity of related costs and potential benefits associated with short-run changes in cultural practices in production systems. The study yielded data that provide consumers with information about the economic and environmental benefits of trees in landscapes, and inform growers' cultural practices.

Why is it important to understand a tree's carbon footprint? The authors of a new study say this vital information can help consumers appreciate the true benefits of planting trees in landscapes, and can also help differentiate horticultural products in the marketplace. According to researchers Charles R. Hall and Dewayne Ingram, authors of a study in the May 2014 issue of HortScience, a plant's carbon footprint is an "impact indicator of primary interest" to growers and consumers because it quantifies the global warming potential of the product.

The carbon footprint of plants and trees, a measure of all greenhouse gases emitted in a product's life cycle, is expressed in units of tons (or kilograms) of carbon dioxide equivalents (CO2e). "Knowing the carbon footprint of production and distribution components of field-grown trees will help nursery managers understand the environmental costs associated with their respective systems and evaluate potential system modifications to reduce greenhouse gas emissions," Ingram and Hall noted. They added that product differentiation is an increasingly important business strategy for burgeoning green industry businesses, and promoting products that offer environmental benefits can be one way to differentiate horticultural products in a competitive marketplace.

The researchers designed a study to capture the economic costs of component horticultural systems while conducting a "life cycle assessment" of the flowering tree 'Forest Pansy' (Cercis canadensis L.) The study incorporated partial budgeting modeling procedures to measure the sensitivity of related costs and potential benefits associated with short-run changes in cultural practices such as transport distance, postharvest activities, fertilization rates, and plant mortality.

Analyses showed that total farm-to-gate-gate variable costs (the seedling, liner, and field production phases combined) was $37.74 per marketable tree; $9.90 for labor, $21.11 for materials, and $6.73 for equipment use, respectively. However, postharvest costs such as transportation, transplanting, take-down, and disposal costs added another $33.78 in labor costs and $27.08 in equipment costs, yielding a total cost from seedling to end-of-life of $98.60. Of the total variable cost, $43.68 was attributed to labor, $21.11 was spent on materials, and $33.81 on equipment use during the life cycle of each marketable tree.

Hall and Ingram say that the study shows life cycle assessment is an effective tool for helping nursery growers understand the inputs, outputs, and impacts of systems producing field-grown trees. "Our findings validate those of previous studies that found that input costs of production processes (machinery, water, fertilizers, pesticides, and energy) are a significant portion of the nursery variable operation costs. Thus, a more efficient use of these environmentally sensitive inputs cannot only reduce production costs for the nursery, but reduce their environmental risks or impacts as well."
