System and method for settling monetary and quota-allocated dual currency transactions

Abstract

A system and method for settling monetary and quota-allocated dual currency transactions may be used to reduce Co2 emissions. Each purchasable item (product or service) in the system may have a monetary price and a Carbon price whose value corresponds to a number of Kg of Co2 emitted by the manufacture/sale/use of the purchasable item. The system and method individualizes the reduction of Co2 emissions and allows each consumer to choose purchasable items in part based on the Carbon price.

What is claimed is: 
     
         1 . A system, comprising:
 a computer system having a processor and a plurality of instructions executed by the processor that is configured to:
 display a purchasable item to a purchaser, the purchasable item having a monetary price and a carbon price, the carbon price having a value corresponding to amount of greenhouse gases emitted during a manufacturing and use of the purchasable item; 
 receive a transaction in which the purchaser chooses to purchase the purchasable item; 
 debit, in response to the received transaction, the monetary price of the purchasable item from an account of the purchaser; and 
 debit, in response to the received transaction, the carbon price of the purchasable item from a carbon account of the purchaser linked to the account of the purchaser, wherein the carbon account receives a yearly allocation of carbon credits. 
   
     
     
         2 . The system of  claim 1 , wherein the processor is further configured to determine, in response to the received transaction, that the purchaser does not have a number of carbon credits in the carbon account of the purchaser to cover the carbon price of the purchasable item, purchase, on a carbon exchange connected to the computer system, the number of carbon credits to cover the carbon price of the purchasable item and debit, for the purchased carbon credits, the account of the purchaser. 
     
     
         3 . The system of  claim 1 , wherein the account of the purchaser is cash and wherein the processor is further configured to present the monetary price and a monetary price of the carbons to the purchaser for the purchasable item and charge, in response to the received transaction, the monetary price of the purchasable item and the monetary price of the carbons to the purchaser. 
     
     
         4 . The system of  claim 1 , wherein the processor is further configured to determine a monetary surcharge for the purchasable item for the purchaser at a particular consumption level. 
     
     
         5 . The system of  claim 4 , wherein the processor is further configured to add an additional monetary surcharge to the carbon price of the purchasable item for the purchaser when the purchaser is at a higher consumption level. 
     
     
         6 . The system of  claim 2 , wherein the processor is further configured to sell, on the carbon exchange, a number of unused carbons by an individual and receive a monetary price for each unused carbon. 
     
     
         7 . The system of  claim 1 , wherein the purchasable item is a product or a service. 
     
     
         8 . The system of  claim 1 , wherein the processor is further configured to determine that the carbon account of the purchaser is not associated to the account of the purchaser and charge, in response to the received transaction, the monetary price of the purchasable item and the monetary price of the carbons to the purchaser. 
     
     
         9 . The system of  claim 1 , wherein the account of the user is linked to a card and wherein the processor is further configured to receive debit information for the card from a point of sale device. 
     
     
         10 . A method comprising: displaying a purchasable item to a purchaser, the purchasable item having a monetary price and a carbon price, the carbon price having a value corresponding to amount of greenhouse gases emitted during a manufacturing and use of the purchasable item; receiving, at a computer system, a transaction in which the purchaser chooses to purchase the purchasable item; debiting, by the computer system in response to the received transaction, the monetary price of the purchasable item from an account of the purchaser; and debiting, by the computer system in response to the received transaction, the carbon price of the purchasable item from a carbon account of the purchaser linked to the account of the purchaser, wherein the carbon account receives a yearly allocation of carbon credits. 
     
     
         11 . The method of  claim 10  further comprising determining, by the computer system in response to the received transaction, that the purchaser does not have a number of carbon credits in the carbon account of the purchaser to cover the carbon price of the purchasable item, purchasing, on a carbon exchange connected to the computer system, the number of carbon credits to cover the carbon price of the purchasable item and debiting, for the purchased carbon credits, the account of the purchaser. 
     
     
         12 . The method of  claim 10 , wherein the account of the purchaser is cash and further comprising presenting the monetary price and a monetary price of the carbons to the purchaser for the purchasable item and charging, in response to the received transaction, the monetary price of the purchasable item and the monetary price of the carbons to the purchaser. 
     
     
         13 . The method of  10  further comprising determining a monetary surcharge for the purchasable item for the purchaser at a particular consumption level. 
     
     
         14 . The method of  claim 13 , wherein determining the monetary surcharge further comprises adding an additional surcharge to the purchasable item for the purchaser when the purchaser is at a higher consumption level. 
     
     
         15 . The method of  claim 11  further comprising selling, on the carbon exchange, a number of unused carbons by an individual and receiving a monetary price for each unused carbon. 
     
     
         16 . The method of  claim 10 , wherein the purchasable item is a product or a service. 
     
     
         17 . The method of  claim 10  further comprising determining that the carbon account of the purchaser is not associated to the account of the purchaser and charging, in response to the received transaction, the monetary price of the purchasable item and the monetary price of the carbons to the purchaser. 
     
     
         18 . The method of  claim 10 , wherein the account of the user is linked to a card and further comprising receiving debit information for the card from a point of sale device.
