| CRC | Carbon Reduction Commitment The Carbon Reduction Commitment (CRC) is an innovative climate change and energy saving scheme for the UK. It will encourage improvements in energy efficiency which can save organisations money. The scheme has been designed to generate a shift in awareness in large organisations especially at senior level, and to drive changes in behaviour and infrastructure. The scheme is also a central part of the UK’s strategy for controlling our carbon dioxide (CO2) emissions. It will tackle CO2 emissions not already covered by Climate Change Agreements and the EU Emissions Trading System. This will help reduce the country’s carbon footprint to deliver the ambitious emissions reduction targets set in the Government’s Climate Change Act. The scheme started in April 2010. | |
