The carbon reduction commitment (CRC) will be exempt from organisations that have more than 25% of their energy and emissions covered by a climate change agreement (CCA). However, these organisations will still be required to register under the CRC in order to set out their legal position.

During the initial stages of registration for the carbon reduction commitment, organisations that are subject to a CCA should still report all half hourly to figures for 2008 in order to be assessed for exemption. Where exemption applies to part of an organisation, the remainder will still be liable to report under the carbon reduction commitment if the total remaining half hourly metered electricity consumption was over 6000 MWh during 2008.
