Energy Efficiency Opportunities (EEO) Program: 2013 Amendments Leighton Contractors is a subsidiary of Leighton Holdings Limited, which is a covered controlling corporation under the federal Government’s Energy Efficiency Opportunities (EEO) Act 2006. In previous years, Leighton Contractors has reported to the public based on financial year reporting periods in order to satisfy EEO requirements. Following amendments to the EEO Regulations in 2013, Leighton Contractors has decided to report on a calendar year basis in order to align with other business publications and changes to our financial reporting period. Going forward, Leighton Contractors will prepare its Public Energy Report based on calendar year reporting, however to ensure full coverage, Table 1.0 of this transitional report will cover the 18 month period from July 2012 to December 2013. Recent amendments also allow for variations in required reporting format, and as such this report has broader coverage than our prior compliance reports and includes case studies of a range of initiatives across the business, regardless of whether these are captured by the EEO Program.

2 Introduction Leighton Contractors Pty Ltd Leighton Contractors is one of Australia’s most recognised, diverse and established industry leaders. We have more than 14,000 people working across Australia, New Zealand, Papua New Guinea and Botswana in Africa. We deliver projects and services to our clients across the mining, energy, utility and power, telecommunications, social infrastructure, property and transport sectors, through our Infrastructure, Mining, Services and Energy Divisions. Increasing pressure on natural resources, coupled with growing community concerns, client drivers and financial incentives, make energy efficiency an obvious focus area for Leighton Contractors. In line with our company value of ‘respect for the community and environment’, we are working to consistently identify and implement opportunities for improved efficiency and environmental performance. We understand that the values and objectives of our clients, contractors and broader supply chain are also shifting towards these goals, creating opportunities for innovation and the achievement of mutually beneficial outcomes. Energy efficiency provides an opportunity to achieve a myriad of business, community and environmental objectives – improving the bottom line of our business operations while reducing energy demand and greenhouse gas emissions.
By integrating efficiencies into our business-as-usual operations, we not only minimise risk but also cultivate opportunities for both ourselves and our supply chain. Our parent company, Leighton Holdings, has been engaged in a wide-ranging business and cultural transformation over this period, with a strategy of ‘Stabilise, Rebase and Grow’ – which focusses on building strong and stable foundations to ensure that future growth is considered, strategic and sustainable. This approach has been embraced within the energy function at Leighton Contractors, with the reporting period spent focussed on building strong, stable and effective foundations for the area moving forward. As noted by Leighton Holdings in their recent Sustainability Report “having an effective and efficient group of Operating Companies will support the transformation of our business and is vital to driving long-term sustainable growth for our shareholders.”

3 Energy management at Leighton Contractors 3.1 Objectives The key objectives of Leighton Contractors Energy Management and Efficiency Program are as follows:
Throughout 2013, we worked closely with the Department of Industry and the Australian Constructors Association (ACA), to determine practical ways to address the difficulties of measuring energy efficiency in the dynamic and variable construction industry.
1. Ensure compliance with all relevant federal energy legislation, including National Greenhouse and Energy Reporting Act From July to December 2013 we identified and reviewed 2007; Energy Efficiency Opportunities Act 2006; and the Clean opportunities for efficiency improvements in our Infrastructure Energy Act 2011. Division, the outcomes of which can be seen in Table 1.0. 2. Develop streamlined processes, tools and knowledge resources for all relevant energy management and efficiency requirements. 3. Work beyond compliance to support and encourage energy and resource efficiency within the Mining Division and office tenancies (not covered by second cycle Leighton Contractors EEO requirements).
Being the first time we had systematically reviewed opportunities within the division, the assessment represents an initial exploration which we will continue to build on over time. We have now identified a suite of applicable efficiency projects which can be reviewed at tender phase for new projects and applied where feasible.
In 2014, Leighton Contractors will be reviewing energy consumption in our Services Division, where we will assess 4. Reduce the energy reporting burden on the business, opportunities for energy efficiency in our tunnel operations across while increasing the accuracy and usability of data through automated data capture, development of performance metrics the country. and effective communication. We will also be working to integrate energy efficiency 5. Engage the organisation through cross functional collaboration considerations into our national procurement processes and agreements, to ensure that our supply chain join us on this to embed energy efficiency across operating areas, with a journey. particular focus on procurement and supply chain. 6. Support the uptake of renewable and alternative energy sources where aligned with our business requirements.
3.2 Progress In 2012/2013, Leighton Contractors focussed on further development of comprehensive and efficient systems, processes and tools for quantifying and reporting on energy consumption and efficiency opportunities across the business. We also developed our Five Year Assessment Plan which outlines timelines and methodologies for assessing 90 percent of our organisations’ energy consumption for efficiency opportunities over a five year period.

3.2.1 Tools and processes – making it easier
3.2.2 Reporting efficiencies and data improvements
At the end of 2012, Leighton Contractors finalised a business standard for energy compliance, covering energy reporting as well as opportunity identification and tracking.
A primary objective during this reporting period was for Leighton Contractors to dramatically improve the efficiency of its energy reporting processes.
A suite of management system processes have also been developed, with tools and knowledge resources to enable our project teams to easily and efficiently identify, implement, track and report on opportunities across the business. In 2013, Leighton Contractors developed a Marginal Abatement Cost Curve (MACC), which allows us to assess our energy efficiency opportunities in terms of cost per tonne of emissions abatement. This tool will provide us with vital information for selecting win-win energy efficiency opportunities and ensuring effective allocation of funds in this area. In 2014, Leighton Contractors will be tracking all approved efficiency initiatives in an internal opportunity tracking system which will be reported periodically to senior management, tracking both energy and financial outcomes.
Our existing energy reporting system was upgraded and enhanced, allowing us to tie in more effectively with finance, safety and procurement datasets. Changes were made to allow for all direct energy purchase data to be captured centrally at the head office, easing the energy reporting burden across our many sites. These changes mean that 74 percent of Leighton Contractors operational control energy data is now captured centrally. We are now working to further streamline reporting via centralised data capture for fuel and electricity that is supplied by our clients or sub-contractors. To achieve this, work will continue in 2014 to link with asset management systems and streamline subcontractor energy reporting processes.
Data Collection Breakdown Operational Control Jul’13 - Dec’13
These achievements are facilitated by the Energy & Efficiency Management Program, which has been developed to guide energy management at Leighton Contractors until 2016. This document continues to develop and will increasingly look to incorporate longer term goals and objectives.

4 Energy consumption The energy consumption represented below is divided into Scope 1 and Scope 2 greenhouse gas emissions, with Scope 1 relating primarily to on-site fuel combustion and Scope 2 consisting of electricity consumed on-site, yet generated offsite.
As a large contractor and services provider, diesel consumed in mobile plant and equipment constitutes the majority of Leighton Contractors annual energy use. Total reportable energy consumption has continued to fall in 2012 and 2013 (Figure 1), partly due to operational control determinations which have resolved that operational control of the mining sites on which we work rests predominantly with our clients.

Figure 3 includes data from sites where Leighton Contractors is deemed to have operational control, removing facilities where other parties hold the energy compliance requirements for that site. It can be seen that energy consumption has reduced overall since 2012; however electricity consumption within the Services Division remains relatively stable, primarily due to the energy intensive ventilation requirements of our tunnel operations. While Services Division electricity consumption was increasing to mid 2013, the divestment of Metronode and Nextgen assets
during the period resulted in a decrease in the latter half of 2013. Energy consumption within the Energy Division also increased, largely as a result of our work on the Gorgon LNG Jetty and Marine Structures and Gorgon LNG Civils and Underground Works projects. Note that the below data only incorporates facilities where Leighton Contractors has operational control. For the Gorgon projects, this includes a small number of Leighton Contractors mainland facilities, such as storage, fabrication and laydown yards.

9 Energy Report 2013 Leighton Contractors
4.1 Energy metrics – measuring efficiency in dynamic and variable industries Leighton Contractors has been capturing energy and greenhouse gas emissions data for a number of years, however there have been many challenges in converting this data into a meaningful representation of efficiency. The ability to form a strong baseline is integral when setting strategic objectives and targets. Much of the work that we perform is in industries where short term, variable projects are the norm and consistency in energy profile is very rare. These characteristics make absolute baselines impractical for our lines of business, where work on a given site may last only 12-18 months and vary dramatically from one month to the next. These variances are typically reflective of the project phase and scope (demolition, construction, commissioning etc), without being indicative of the efficiency of the project operations. In this context, Leighton Contractors has been working hard to develop efficiency metrics which are meaningful and representative in such variable industries.
This work has been progressed via consultation with the industry and regulators. It is evident, however, that there is still work to be done in order to find meaningful indicators which can practicably be recorded and reported across our many sites. During this reporting period, we have developed high level intensity metrics based on the business’ annual revenue and man-hour data, which establish a useful foundation for further work in this area.
4.2
Normalised performance data
The below graph (Figure 5) shows energy consumption relative to company revenue from January 2011 to December 2013. This identifies the Mining and Services Divisions as the more energy intensive lines of business relative to turnover. For the Services Division, this is due primarily to tunnel operations and maintenance projects. Prior to the divestment of Metronode and Nextgen, data centres within the Telecommunications area were also responsible for higher energy intensity within that division. Mining Division has continued to decrease in regards to its reportable energy intensity, primarily due to progressive clarification of operational control determinations which have identified that these operations fall outside of Leighton Contractors reportable corporate energy profile.

Figure 6 looks at energy consumption relative to man-hours (million hours worked) to track energy intensity across the business relative to human resourcing inputs. These metrics show a relative consistency over time and suggest that such measures are suitable for tracking at a divisional level moving forward, as a representation of energy intensity.
Leighton Contractors will continue to work towards more detailed, activity level indicators, with the aim of identifying metrics which achieve the required granularity, while also being suitable for company-wide tracking and reporting.

5 2013 EEO Program energy assessments During the reporting period, Leighton Contractors undertook the first energy assessments of the second cycle of the Energy Efficiency Opportunities Program. These assessments were focussed on energy consumption within the company’s Infrastructure Division and a range of feasible opportunities were identified. The assessments aimed to focus on elements of our work which remain relatively consistent across the division and can be applied to a wide range of projects. Through this process, Leighton Contractors was able to identify potential energy savings of over 60 000 Gigajoules almost 70 000 tonnes of greenhouse gas emissions. These initiatives
represent significant opportunities for Leighton Contractors and efforts in 2014 will focus on assessing site specific applicability for future projects; assisting in project implementation and tracking efficiency outcomes. The below table outlines the energy saving opportunities identified as part of the EEO assessment process in 2013. As per EEO Program specifications, this data only includes projects where Leighton Contractors is deemed to have operational control and covers initiatives aimed at reducing direct on-site energy consumption only. Opportunities identified to reduce embodied energy or emissions in the supply chain or broader project lifecycle have not been included.

6 Highlights – energy savings In addition to the above assessments and our focus on system and process establishment, a range of direct and indirect energy saving initiatives have been undertaken across the business. Below is a snapshot of some of the great work occurring throughout our business during the reporting period. Note: These case studies are business-wide and are not restricted to compliance initiatives under the EEO program. For transparency, where a site or business unit does not fall within Leighton Contractors operational control under the EEO Act, this has been identified with an ‘*’.
in 2013, it has been recognised as a national leader in sustainable construction. The project team aimed to identify and integrate efficiencies through the project life-cycle. Initiatives ranged from efficient haul road design, to on-site re-use of materials, innovative engineering and design, solar powered weather and repeater stations, through to GreenPower procurement and energy efficient site facilities.
Laverton Plant Yard, Victoria With energy assessments undertaken by the Infrastructure Division in Victoria in late 2013, the team has already acted to pursue opportunities for Solar PV and LED lighting upgrades at the Laverton Plant Yard, resulting in annual savings of 60 tonnes of greenhouse gas emissions per annum. This includes annual production of over 28 000 kWh of solar power, and efficiency improvements of over 23 000 kWh per annum. Feasibility assessments are now underway across Leighton Contractors to identify further opportunities for implementation across our longterm facilities.
Kempsey Bypass Alliance, New South Wales United Nations Association of Australia Sustainability Award Due to its size and scope, the Kempsey Bypass Alliance project was one of Leighton Contractors largest energy consuming construction projects during the reporting period. As winner of the United Nations Association of Australia’s Sustainability Award
Efficiency considerations in haul road design, for example, alleviated the need for heavy plant to brake and stop to give way to other large vehicles at crossing points, improving productivity and reducing carbon emissions. Where suitable, crossing and haul roads were also levelled or reduced in grade to reduce plant acceleration and reduce emissions and noise pollution. These design changes alone were responsible for abatement of approximately 3400 tonnes of CO2-e during the construction phase. Re-use of 180 000 cubic metres of excavated material on the project was responsible for achieving significant emissions abatement through the avoidance of unnecessary haulage offsite. While the material was previously considered unsuitable in meeting specifications, ongoing consultation and engineering efforts meant that on-site re-use was ultimately achieved by the team, minimising both landfill and haulage impacts, as well as reducing project costs. This initiative also led to the modification of earthwork specifications, opening the way for such initiatives to occur more readily on future projects. The project’s office energy efficiency initiatives are also estimated to have reduced electricity consumption by approximately 12 percent during the construction phase.
13 Energy Report 2013 Leighton Contractors
Mining Division – Metals* The adoption of vertical tyre transport commenced as a pilot project in the Pilbara from mid 2013. Rather than the traditional horizontal tyre transport methods, vertical transport not only increases safety (by eliminating the over width safety concern for oncoming motorists), but dramatically reduces energy consumption. This is due to the fact that rather than requiring three prime movers and three escort vehicles, vertical tyre transport requires only one prime mover. Given the 2800 kilometre round trip from Perth to the site, this initiative alone is estimated to have reduced diesel consumption by approximately 230 000 litres in 2013.
Initiatives implemented on the project included the use of biodiesel generators on site, GreenPower procurement, engineering and design improvements and the re-use of over 4000 cubic metres of spoil. Scope 3 emissions were reduced through selection of materials with lower embodied energy, for example, an average recycled content of 85 percent for steel reinforcing bar and 66 percent for reinforcing rod. Lifecycle emissions were further reduced thanks to a recycling rate of 98.59 percent for the project.
Regional Rail Link Package E* – Deer Park to West Werribee Junction (Baulderstone Leighton Joint Venture) At the Regional Rail Link Package E project, biodiesel was again used for site generators, abating almost 60 tonnes of greenhouse gas emissions and avoiding 141 000 litres of regular diesel consumption. Green office programs aimed to influence employee behaviour and energy efficient appliances were selected for site facilities, as well as solar panels on site weather stations. These minor adjustments are actions which are being adopted across many Leighton Contractors sites and help to reinforce the culture changes required to foster large scale engineering and equipment efficiency improvements.
Offices Regional Rail Link Packages, Victoria Regional Rail Link Package F - West Werribee Junction (Leighton Downer Joint Venture) This project embedded sustainability considerations throughout the project lifecycle, from energy and carbon to water, waste, materials and social impacts. In total, 22 targets were set to track and manage performance in these areas across the construction phase. At project completion, the team exceeded its energy and carbon targets, reducing construction emissions by over 22 percent relative to the reference design benchmark. These savings resulted in abatement of 2653 tonnes of CO2-e emissions. Energy performance was improved by almost 21 percent below the benchmark design, equating to 6803 GJ of direct fuel and electricity savings, and 26 016 GJ of embodied energy saved throughout the project.
Improving efficiency across the board Across the country, Leighton Contractors is working to bring together its businesses in each region under one roof, strengthening our capacity for teamwork and creating a strong and unified brand presence for our supply chain.
14 Energy Report 2013 Leighton Contractors
With ‘respect for the community and environment’ as one of Leighton Contractors’ core company values, the importance of constructing headquarters with strong environmental performance credentials was clear. The new Leighton Contractors Workplace Standards establish an objective of 5 Star Green Star Office Design and Interiors Ratings, as well as 5 Star NABERS operational energy ratings for all new workplaces. Taking the lead of Leighton Contractors’ Brisbane HQ Building, which achieved a 6 Star Green Star Office As-Built v2 Rating, 2013 saw the Perth HQ achieve a 5 Star Green Star Office Design V3 rating, with the upcoming Sydney and Melbourne offices both targeting 5 Star Green Star Office V3 (Design and As-Built) Ratings, as well as targeting 5 Star Green Star Office Interiors V1.1.
To this end, we are working to utilise the Le3 equations as a key measure in improving our mining efficiency.
City East Alliance, Western Australia Australia’s first rating under the Infrastructure Sustainability (IS) Rating Tool In 2013, the City East Alliance Project was awarded the first IS Rating in Australia due to efforts in conserving energy and water, using recycled materials and leaving positive community legacy.
To further embed Leighton Contractors commitment to energy efficiency in the workplace, a national office efficiency program is under development to ensure that all regional headquarters are actively managing their energy consumption, identifying efficiency opportunities and setting performance targets. The program incorporates national involvement in the Government’s CitySwitch tenancy energy management program and will require each regional office to obtain NABERS Energy Ratings to assess operational energy performance. These initiatives, ratings and programs combine to create a strong national approach to energy efficiency and environmental performance in Leighton Contractors’ offices. Looking forward, efforts will expand to temporary site offices in order to achieve full coverage across the business.
Plant Department The Leighton Contractors Plant Department has continued to identify, measure and implement energy efficiency opportunities throughout their operations during the reporting period. In 2013, the team were able to extend oil life intervals of selected plant by increasing sump sizes, eliminating 250 hour services and installing long life filters. Another initiative involved varying final drive oil viscosity in order to test the theory that thinner oil would reduce friction and improve efficiency. Unfortunately, measurement of outcomes in the trial versus control periods was masked by unavoidable changes to the haul gradient on the trial site, meaning that further investigation is required. Overall, however, the team has concluded that effective and efficient mine planning remains the most significant opportunity for energy savings across our mining operations.
The team utilised recycled asphalt pavements to reduce embodied energy as well as reducing landfill requirements and minimising demand for virgin material. The project also utilised Warm Mix Asphalt, helping to dramatically reduce the energy required for aggregate and bitumen heating. Warm Mix Asphalt allows asphalt production to take place at temperatures up to 30ºc lower than traditional products, reducing the overall energy demand. This was the first time that the product had been trialled to this extent in Western Australia. The project further reduced embodied energy in materials by using approximately 160 000 tonnes of comingled recycled concrete – the largest use of this material on a Main Roads WA project to date. IS Accredited Professional training has now been undertaken by more than 20 Leighton Contractors employees Australia-wide.

M80 Ring Road, Victoria
ChargePoints with their mobile devices, or via a ChargePoint card. Through the network, ChargePoint also notifies drivers and station managers of charging status and faults. During the reporting period, ChargePoint provided over 120 MWh of accredited GreenPower to electric vehicles around the country, making a tangible contribution to the development of cleaner, more efficient transport and infrastructure solutions across Australia.
Leighton Contractors’ M80 Ring Road Upgrade project team has put solar panels to their most innovative use along a 500m stretch of the newly widened freeway. The power produced is fed into the Victorian electricity grid, where it offsets energy used by the street lights, illuminated signage and CCTV systems. The installation is expected to generate over 54000 kWh per annum. Installed along the southern edge of the Sunshine Tip Structure, the installation is made up of modular solar panels fixed to galvanised steel sheeting and cantilevered posts. The resulting wall extends up to 4 metres high and 500 metres long. The M80 solar wall is the first time that a large solar plant has been installed on a road project exclusively for power generation.
The combination of ChargePoint’s smart charging hardware and network services will also provide opportunity for business units and their fleets to move towards a more sustainable transport platform while reducing running costs. Using a standard Leighton Contractors fleet vehicle as an example, converting to a plug-in range extended vehicle will save over 9,000 litres of fuel and 13 tonnes of CO2 emissions, while significantly reduce operating costs over a typical lease life. It is expected that these plug-in vehicles will be seen within the fleet from mid-2014.
Products, services and lines of business ChargePoint: Leading the charge on electric vehicle infrastructure In 2013, Leighton Contractors continued to expand Australia’s electric vehicle charging network via ChargePoint Pty Ltd. ChargePoint commenced operations in 2008 and holds the exclusive Australian and New Zealand license for electric vehicle charging technology developed by Silicon Valley based company ChargePoint Inc. ChargePoint is Australia’s largest open access and customer owned electric vehicle charging network, with sales, installation and service representation across every major capital city. ChargePoint currently has over 190 installations across Australia and delivers GreenPower driving no matter where drivers charge, by ensuring 100 percent accredited renewable energy is purchased for every kWh used in vehicle charging. The network services allow drivers to locate, navigate, reserve and operate
Macarthur Wind Farm*, Victoria: Increasing Australia’s renewable energy capacity In January 2013, Leighton Contractors completed construction of the 420MW Macarthur Wind Farm – currently the largest of its kind in the southern hemisphere. Consisting of 140 3MW turbines, the facility provides enough renewable energy to power approximately 220 000 average Victorian homes per annum, avoiding around 1.5 million tonnes of greenhouse gases per year. In 2013, Leighton Contractors also completed the 55MW Mumbida Wind Farm project; a 22 turbine wind farm located about 340km north of Perth on Australia’s West Coast.
