Contextual parameters represent non-technological values that influence the sustainability of technologies, especially at the deployment stage. These parameters are intended to capture the specific circumstances in which the technology would be deployed. They reflect the local and regional nature of primary stressors to humans and the environment, accounting for economic (e.g., tax rates, unit costs), environmental (e.g., ambient temperatures), social (e.g., household size), political (e.g., regulations), and other conditions in which the system exists. As one example, outcomes associated with energy-intensive technologies may be especially sensitive to the characteristics of the local electricity grid, which can vary widely across and within countries.
