Carbon Footprint Analysis For Awa

摘要

In line with taking leadership within the corporate sustainability field, AWA has conducted an analysis on their carbon footprint with the help of Dr Michael du Plessis of Greenice.rnA carbon footprint is the total amount of carbon dioxide and other greenhouse gases (like methane, sulphur dioxide etc) emitted over the full life cycle of a product or service. Greenhouse gas emissions are tracked along the full life cycle of the product or service from where raw materials are sourced (mined or grown) through to consumption and eventual disposal.rnThe model used to calculate AWA's carbon footprint was developed by the Centre of Integrated Sustainability Analysis (ISA) at the University of Sydney and uses Input - Output analysis, a Nobel Prize winning macroeconomic theory. The model uses an organisation's expenditure and revenue data alongside onsite energy consumption from fuel, gas etc to calculate a total carbon footprint that includes supply chain impacts. Simply put, the ISA model works out the amount of CO_2-equivalent "embodied" in the $ value of the purchases plus CO_2-equivalent emissions that come from burning of fuels onsite.
