These Regulations concern the scheme providing for a reduced rate of climate change levy (“CCL”) established under Part IV of Schedule 6 to the Finance Act 2000 (c. 17). A facility which receives supplies of energy and which has entered into a climate change agreement (a voluntary agreement between such a facility and the Environment Agency) must meet targets for energy use or emissions which are specified in the agreement during a target period. If it does, it is eligible for a reduced rate of CCL during the certification period which is specified in the agreement in relation to that target period. If a facility does not meet any target for a target period, it may pay a buy-out fee on each tonne of carbon dioxide equivalent by which it falls short of meeting that target, and thus remains eligible for the reduced CCL rate.
