Carbon as a currency− Evolving client requirements − Increasing interest in carbon foot printing − Supply chain reporting − Low carbon solutions− Driving force behind green business − Quantifiable − Linked to financial benefit − Tradable− CRC / Greenhouse Gas Reporting Regulations
Skanska Achievements− CRC is worth around £200,000 to Skanska UK− Developed a bespoke reporting system to address CRC legislation− Since 2008 our total emissions have dropped by 7.5%− Green Car policy and vehicle tracking on commercial fleet represent bulk of this 7.5% reduction − 60% of staff car fleet now 130gCO2 or below − Average emission from Skanska vehicle down from 9.9TCO2 per year to 8.53TCO2 per year− Since 2005 CO2 emissions at head office reduced by 18% and continuing to drop
