EnviroCalc is a spreadsheet-based tool designed to estimate the environmental benefits of purchases of recycled-content and energy efficient products. It combines a wide range of available methodologies and models for assessing the environmental impacts of purchasing into a single tool. One of the advantages of the tool is that all the calculations are based on reporting information that are easily obtained from product suppliers (e.g. product quantities purchased, individual item shipping weights, etc.), making it easy for a purchasing official to obtain credible environmental benefit and cost saving estimates.
