The early action metrics form 100% of the league table assessment criteria during the first year of the carbon reduction commitments scheme, and a significant percentage of the second and third years. In order to acheive the Early Action Metrics, most CRC participants will need to implement Automatic Meter Reading equipment and obtain the Carbon Trust Standard (CTS)*, or equivalent.

*In addition to the Carbon Trust Standard, participants can use any equivalent energy management scheme. However, as of May 2010, the Carbon Trust Standard is the only scheme that is currently approved by the CRC.
