Patent ID: 8504306

Claim:
A method for evaluating greenhouse gas (GHG) emissions by an entity comprising: a. receiving a transmission from the entity conveying the entity's usage of resources for past times; b. receiving another transmission from the entity conveying one or more strategies proposed by the entity for reducing future GHG emissions, each strategy having a start time and each strategy relating to the entity's expected usage of the resources for future times; c. deriving, using a programmed processing system, past GHG emissions by the entity from information received in step a, a baseline level of future GHG emissions by the entity from the past GHG emissions assuming no strategies for reducing future GHG emissions are implemented, and estimated future GHG emissions by the entity for implementing each of the one or more strategies from information received in step b; d. converting, using the programmed processing system, the past GHG emissions, the baseline level of future GHG emissions, and the estimated future GHG emissions into a chart for viewing by the entity, the chart comprising: a horizontal axis indicating past times and future times; a vertical axis indicating amounts of GHG emissions; a first portion bounded by the horizontal axis and the vertical axis identifying the past GHG emissions along the horizontal axis; and a second portion bounded by the horizontal axis and the vertical axis identifying the estimated future GHG emissions along the horizontal axis, the second portion indicating: the baseline level of future GHG emissions; reductions of the baseline level of future GHG emissions due to implementation of each strategy identified in step b, wherein the one or more strategies are presented as lines of future GHG emissions below the baseline level of future GHG emissions in an order based on their start times, a first line is a first reduction of future GHG emissions from the baseline level of future GHG emissions, and each subsequent line is a subsequent reduction of future GHG emissions from the preceding line; and e. transmitting the chart to allow evaluation of the effect of each strategy on the estimated future GHG emissions.
