Global temperature regulation, by the green house effect, is well documented and clearly understood. However, only relatively recently have the consequences of anthropogenic atmospheric emissions, such as the release of CO2, become apparent. For many businesses, an increasingly common corporate responsibility strategy is to invest in the capacity to sequester atmospheric CO2, typically through replanting woodlands. The process of photosynthesis derives sugars from CO2 and sunlight, so “captures” atmospheric CO2. Research has shown that PrimoMAXX (Trinexapac-ethyl, a late gibberellin (GA1) biosynthesis inhibitor) has a number of beneficial effects for the maintenance of amenity turf including the reduction of turf growth for extended periods of time (Ervin and Koski, 1998; Ervin and Koski. 2001a; McCann and Huang, 2007). This reduction in growth has associated reductions in the costs of maintenance due to less mowing, irrigation and fertilizer being required (Ervin and Koski. 2001b). This study used the CranTurfC model (Bartlett and James, 2010) to calculate the carbon footprint and associated financial costs of maintaining turfgrass using PrimoMAXX. We aimed to determine, if the carbon footprint of sports surfaces is reduced through the application of plant growth regulators.
