Method for reducing the carbon footprint of a community by implementation of a water filter project comprises assessment of the viability of a filter system to determine the acceptability of said filter system for implementation in a community as substitute for the sterilization of water by boiling. Filter systems are transported to a community, for example a developing country where water is sterilized by boiling on a routine basis due to the presence of waterborne illnesses. The filter systems are then installed and operated. The volume of water produced by the filtering system is then monitored and usage data is generated and communicated to a database. The volume of carbon credits associated with the usage data is calculated. Information is communicated to a consumer of carbon credits. Funds are then transferred from said consumer to a person or persons, i.e. the project proponent, providing and installing said filter system.
