Both public and private sector organisations must make an information disclosure under CRC if they had one or more half hour electricity meter at any time during 2008.

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.

The Carbon Reduction Commitment's 90 percent emissions rule, otherwse known as the 'flexible de minimis' rule, requires all particpants to account for at least 90% of their total carbon footprint emissions. The 90% rule aims to focus attention on the largest, and most cost effective, opportunities to reduce carbon emissions.

The 90% emissions rule can include all energy reported through the Climate Change Agreement, European Union Emissions Trading Scheme, as well as all 'Core Sources' of non-transport energy consumption.

2008 -- the period from January 2008 to December 2008 will be used to identify which non-energy intensive organisations in the UK have consumed more than 6,000 MWh of half hourly metered electricity.

July 2009 - The Environment Agency issued letters to the billing address of all half hourly metered properties toi make them aware of the Carbon Reduction Commitment.
