Abstract: The methods and systems described herein encourage reductions in the production of pollutant gases by converting the individual's local efforts into a demonstration of the individual's global impact. The systems and methods enable an individual to establish a network of associated individuals. The efforts of the individuals within the network are then associated in a way that enables the individuals to see the results of their own efforts and the results of others they have influenced. Individuals in the network may be associated in a hierarchical-type structure, similar to a family-tree type structure, and some or all of the carbon savings of descendants may be attributed to the parent, grandparent, etc. Any of a variety of computational methods may be applied to reward an individual for efforts to encourage others to reduce the production of pollutant gases.
