Calculation

This calculation uses version 56bd02c of Brighter Planet's residence carbon model.

Calculations are performed adaptively, so methodology will vary depending on residence characteristics. Impact values, listed below, are based on a number of input factors, which in turn are based on others, and so forth. In each case, the methodology used in the calculation is specified, and, wherever possible, the source code of the method is displayed.
