<pp> 71 Appendix 7 Our Office-Based Environmental Performance We continued our focus on improving operational sustainability through our environmental management system (EMS). We measured resource use and set annual targets, and in 2012 to 13 continued to maintain ISO 14001 certification for our EMS. Performance results compared to last year were mixed, with electricity use, potable water use and vehicle emissions increasing, and paper use decreasing. during 2012 to 13, the Urban Workshop blackwater treatment facility was not operational, resulting in an increase in potable water use. An increase in vehicle emissions was predominantly due to an increase in kilometres travelled, which reflects our greater regional focus. Figures based on activity per employee were also affected by current staff numbers (103 FTE) compared to the previous year (128 FTE). In 2012 to 13, emissions from staff commuting to and from work were included. The inclusion of these data led to an increase of nearly 27% in the organisation's total GHG emissions.
