The Carbon Trust Standard essentially requires an organisation to calculate its carbon footprint (including transport), demonstrate absolute or relative reduction in carbon emissions by more than 2.5 percent per year, and demonstrate good carbon management.

As of January 2009, the required standards for automatic meter reading equipment have not yet been published. However, during summer 2008 the government published draft consultation on the Carbon Reduction Commitment and it is considered that the standards published in that document will not change with regards to Automatic Meter Reading equipment.
