Towards Zero Net Emissions for the NAGA Region (TZNE) outlines a new approach to regional cooperation to achieve significant reductions in greenhouse gas emissions across northern metropolitan Melbourne. This strategic blueprint outlines a comprehensive set of strategies and actions spanning key sectors in the region. By harnessing the combined capabilities of its members, and their connection with local communities, the TZNE plan demonstrates how members of the Northern Alliance for Greenhouse Action (NAGA) can effect greater change than any one member could achieve alone.
Since its inception in 2002 NAGA has been at the forefront of a regional approach to reduction of greenhouse gas emissions. NAGA began operating as an informal network to share information, coordinate community emission reduction activities and cooperate on the research and development of innovative corporate emissions projects. The members of NAGA are the Cities of Banyule, Darebin, Hume, Manningham, Melbourne, Moreland, Whittlesea, Yarra, Nillumbik Shire Council and the Moreland Energy Foundation Limited (MEFL). Approximately 25 per cent of the population of Melbourne lives in the NAGA Region. The geographic extent of the NAGA region in relation to the greater Melbourne metropolitan area and the recommended urban growth boundary is provided in Figure 1.

The goal of NAGA is to achieve significant greenhouse reduction by delivering effective programs and leveraging council, community and business action. With continued growth in the level of anthropogenic greenhouse gas emissions in both Victoria and Australia, there is general consensus around the need for NAGA to rapidly scale up its approach and effort to reduce emissions and transition to a low carbon future.
TZNE responds to this urgent need by providing for the first time in Australia a comprehensive and evidence-based regional strategic direction for reducing greenhouse gas emissions to 2020 and providing the framework by which zero net emissions can be realised. implementation of TZNE will provide a significant contribution to driving emissions reduction within Australia, and will drive innovation and research in relation to technological, governance and policy approaches to mitigation. As such it is expected to provide a template by which regional action can be implemented, both within Victoria and across Australia. For NAGA as an organisation, implementation will create a new era of collaboration and ensure it remains a leader in regional approaches to emissions reduction.
The focus of TZNE is based on the 2005/2006 and projected 2020 emissions profile of each NAGA municipality and the region as a whole. This understanding of the emissions profile has been overlaid with an assessment of current best practice at an international, national and regional level and tested through a series of industry workshops. The resulting direction reflects an approach that is currently feasible, relevant and central to the role of NAGA as an agent of change.
TZNE provides a pathway for action with multiple strategies reflecting key emission sectors within the region. For each strategy a series of sub-strategies are defined for the initial three years and then outlined for 2012-2015 and 2015-2020. Each sub-strategy specifies the pathway to reduction, delivery mechanism, implementation steps, potential barriers, modelled reduction in greenhouse gas emissions by 2020 and NAGA member or members proposed to lead its implementation over the initial three year period. The final component of the mitigation approach details an approach to offsetting residual emissions.
The identification of lead NAGA members has been designed to build on the existing approach to collaborate within the NAGA membership, provide a clear role for members and deliver benefits to all with the most efficient investment of funding and time. A key benefit is the economies of scale that can be achieved through scaling up action to enable regional delivery.
TZNE also provides an overview of the contribution the Federal and State governments can provide to achieving zero net emissions within the NAGA region. indicative costs and the NAGA governance structure have been considered. There is an expectation that the strategy will require updating in 3 years, given rapid changes in community expectations, technology, policy, administrative and governance approaches to mitigation.

The NAGA region represents a diverse range of urban forms from inner city to rural fringe and this is reflected in the regional emissions profile, with no one sector dominating. The largest contributors to regional emissions are the industrial, commercial and residential sectors. private vehicle use provides the fourth largest contribution to emissions within the NAGA region. Figure 2 illustrates the relative contribution of each sector to emissions across the region and the predicted change to 2020 under a business as usual scenario. over this period there is expected to be a relative decline in the contribution to emissions from the manufacturing sector and an increase from the residential and commercial sectors, reflecting the changing nature of employment and continued population and residential growth within the NAGA region.
The total greenhouse gas emissions of the NAGA region for 2005/2006 were 21,051 kilotonnes of carbon dioxide equivalents (kt Co2-e) and this is projected to grow by 18.8 per cent to 25,012 kt Co2-e in 2020 without the implementation of TZNE. Growth in emissions is primarily attributed to the growth in the number of households and population predicted over the period from 2005/2006 to 2020.

The emissions profile for the NAGA region provided a basis on which strategies to mitigate emissions were developed. industrial, commercial, residential and transport were the sectors identified as generating the largest emissions contribution. A fifth strategy, decarbonising the energy supply, was also identified to reduce the carbon intensity of electricity supply to all sectors.
Within each of these strategy areas, specific actions or sub-strategies were developed through a two stage process. A paper was produced highlighting international, national and local approaches to mitigating emissions within each sector, considering both technological as well as governance and administrative structures. The paper was then used to provide context to a series of NAGA and industry sector workshops to refine the sub-strategies. The workshop sessions considered the ease of implementation, potential emission reductions and applicability in terms of governance, geography, and regional and individual member emissions profiles.
Each sub-strategy is described in terms of the rationale and supporting emission profile for its recommended initiative, the mechanism for delivery, next measures to be undertaken and potential barriers to implementation. A lead NAGA member or members has been proposed to build on existing expertise, achieve greater benefit through distributing and sharing responsibility and ensuring accountability. The modelled emissions reduction for each sub-strategy has also been determined. This contributes to an overall emissions reduction associated with implementation of each strategy.

reSidential StrateGy Residential sector emissions in the NAGA region in 2005/2006 were 17.1 per cent of total emissions. Due to the projected increase in population within the NAGA region to 2020, the overall proportion of emissions from this sector is anticipated to increase to 19.5 per cent, or 4,893 kt Co2-e. The approach to mitigating emissions within the residential sector is provided in Table 3 and is modelled to provide an annual reduction of 1,317 kt Co2-e of emissions by 2020.
decarboniSinG enerGy Supply A significant portion of Victoria’s energy is supplied through brown coal, the most greenhouse gas intense form of energy generation. in addition up to 3.5% of energy is lost to the network through the generation of heat during transmission from remote locations and subsequent distribution to urban areas. While demand reduction and efficiency measures can reduce the need for energy, underlying pressures from population and subsequent increases in housing stock and commercial and industrial facilities will, to a degree, nullify the effect of these measures without a strategy that addresses the need to decarbonise the energy supply. Table 4 outlines the approach to decarbonising the energy supply within the NAGA region. When implemented, it is expected to contribute to a reduction of 1,579 kt Co2-e per annum by 2020.
tranSport StrateGy The transport sector was calculated as comprising 20.9 per cent of emissions for the NAGA region, representing 4,420 kt Co2-e for 2005/2006 and increasing to 5,231 kt Co2-e by 2020. Within the transport sector, private vehicle use provides the largest contribution to emissions. implementation of the sub-strategies contained in Table 5 is predicted to reduce annual emissions by 158 kt Co2-e by 2020.

Each of the five mitigation strategies provides a contribution to emissions reduction and represents a balance between our current understanding of what can be practically achieved by 2020, the need for significant emissions reduction and the capability of NAGA members to progress mitigation actions.
Through the implementation of each strategy it is predicted that an annual emissions reduction of 6,086 kt Co2-e, or 24.3 per cent, can be achieved by 2020. The proportion of emissions reduction in comparison with a business-as-usual scenario is provided in Figure 3.

federal, State and indiVidual council contribution TZNE represents a regional approach to greenhouse gas reduction. it demonstrates what can be achieved to move towards zero net emissions by 2020 through leadership, advocacy and driving innovation. A range of issues that will influence the future emissions profile of the NAGA region, including a reduction target under an emissions trading scheme, the density and energy efficiency of new development, and public transport provision, rest with other levels of Government. They, in turn are influenced by the demands and pressures placed on them by business and the community.
To achieve zero net emissions there will need to be alignment and concerted effort in regards to policies and actions by the Federal and State Governments, individual Local Governments’ mitigation strategies and the contribution of businesses and individuals. These multiple contributions are required to achieve significantly greater reductions demanded by the climate science. TZNE represents a realistic step in the process.
offSet StrateGy The final element is to offset the residual emissions, whereby emission reductions are carried out by a third-party. Within the existing Federal Government policy context of a proposed Carbon pollution Reduction Scheme (CpRS), the strategy outlines the three options for NAGA members to offset emissions, namely:
purchase of international offsets �Establishment of biosequestration �purchasing units from within the CpRS. �
To finance the offset program it is proposed that NAGA establish an offset fund to assist member Councils and community members to reach a zero net position. A centralised fund will reduce transaction costs and ensure the purchase of high quality offsets.
The proportion of emissions to be offset will be dependent on the contribution of Federal and State policies on emissions reduction.

10 Towards Zero Net Emissions for the NAGA Region: Executive Summary 2009
TZNE presents a new approach to collaboration at a regional level. Based on analysis of local and regional emissions profiles, it provides a comprehensive pathway to achieve greenhouse gas reductions in northern metropolitan Melbourne. TZNE outlines the enabling role that local governments can play in driving change, made stronger by combining efforts and leveraging their connection to local communities.
A summary of the applicability of each strategy and the supporting sub-strategies to each NAGA municipality is provided in Table 6. The full TZNE report (accessible from www.naga.org.au) provides detailed actions and timeframes for each of the strategic areas and defined sub-strategies and in doing so provides clear direction for NAGA members to 2020.
TZNE will guide a new era of collaborative action for NAGA and will provide a significant contribution to driving emissions reduction within Australia.
