The UK glass manufacturing sector has successfully completed its second Climate Change Agreement Milestone Year with an improvement in efficiency of 11% in terms of MWh/tonne glass-packed from its base year position. This compares against the "Milestone 2" target of 6%. In 2001, the UK glass sector voluntarily entered a 'Climate Change Agreement' (CCA) with the government. In return for taking on & meeting challenging energy efficiency targets, members of the agreement receive 80% relief from the CCL, an energy consumption based tax introduced to promote energy savings in industry & commerce. Under the CCA, targets are held for 2002, 2004, 2006, 2008 & 2010, representing an approximate saving of 13% across the life of the agreement against the glass sector's 1999 base year performance.
