Patent ID: 8543585

Claim:
A method of providing a carbon footprint comparison, the method comprising: accessing first profile attributes and a first carbon footprint of a first user, each of the first profile attributes defining a mode of living of the first user that cause emissions of greenhouse gases; accessing a carbon footprint and profile attributes of additional users, each of the profile attributes defining a mode of living of each of the additional users that cause emissions of greenhouse gases; determining that the first user and each of the additional users are a match based on identifying a number of matching profile attributes from the first profile attributes and the profile attributes of each of the additional users; determining a match strength value for the first user and each of the additional users, the determining of the match strength value comprising: accessing a list of predefined strength values and a set of available profile attributes corresponding to each of the predefined strength values; counting the identified matching profile attributes included in the set of available profile attributes; and comparing the count to the list of predefined strength values; determining that the match strength value for the first user and each of the additional users is identical; calculating an average group carbon footprint corresponding to a group of users with the match strength value based on the carbon footprint of each of the additional users; and presenting a comparison of the first carbon footprint with the calculated group carbon footprint corresponding to the group of users with the match strength value.
