This refers to the environmental impact of a company’s operations, with a primary focus on climate change issues. The model currently focuses on Scope 1 and Scope 2 data, and does not measure any down-stream or upstream impacts. The model calculates environmental impact as follows:
Environmental Impact i,t
= Environmental Impact of Emissions i,t + Environmental Impact of Water i,t
= (Σ (Emissions Volume e,i,t * EPS Monetary Coefficient e)) + (Water Production & Delivery Cost i,t + Wastewater Treatment Cost i,t)
= (Σ (Emissions Volume e,i,t * EPS Monetary Coefficient e)) + ((Net Water Consumed i,t * AWARE Factor j,t * Water Production and Delivery Unit Cost j) + (Net Water Consumed i,t * Wastewater Treatment Unit Cost j))
Where i refers to the environmental impact of an organisation, in year t.
