A study out of the University of Kentucky provides a base of understanding of carbon footprint terminology and illustrates carbon footprint analyses using data from previous research that modeled nursery and greenhouse crop production systems and their life-cycle impact. Dewayne Ingram, Charles Hall, and Joshua Knight present the science underlying the determination of carbon footprint and the degree to which it is important in minimizing the negative impacts of new product development and assessing the positive or negative cradle-to-grave life-cycle impacts.
