Climate Change Agreement (UK)

When the Climate Change Levy was introduced in the United Kingdom, the position of energy-intensive industries was considered, given their energy usage, the requirements of the Integrated Pollution Prevention and Control regime and their exposure to international competition. As a result, a 65% discount from the levy was allowed for those sectors that agreed targets for improving their energy efficiency or reducing carbon emissions.
