refereed paper carbon footprint water NOVEMBER 2012 75 The adopted strategy trajectory includes 16 abatement opportunities (Table 1). It also includes a mix of different types of abatement opportunities (Table 2). The community abatement program opportunities account for over 39% of the overall abatement potential. This is a reflection of the relatively large emission profile of the community compared to Council operations. The GHG capture and destruction category (34%) is dominated by the opportunity to increase the capture and destruction of methane gas from the Council landfill. The demand management and energy efficiency opportunities (19%) generally had a lower levelised cost of abatement. The renewable energy opportunities included solar hot water systems and cogeneration using biogas from the wastewater treatment plant. Conclusions The Climate Change Mitigation Strategy, endorsed by Gosford City Council, includes: • Council adopting a carbon reduction target of 20% at 2025 (based on 2010 levels), with funding to be allocated to the mitigation projects as part of future Integrated Planning and Reporting processes; • Council developing a Carbon Management Response Plan (CMRP) to assist the implementation of the above target; • Council undertaking further investigations into abatement opportunities identified as having potential to generate positive financial returns. The Climate Change Mitigation Strategy project demonstrates that significant emissions reduction is achievable at Gosford City Council and if implemented will deliver sustainable (financial, social and environmental) value to Council and the community.
