Organisations can undertake a self-assessment of their projects or assets, which can be a useful internal exercise, but to promote a rating publicly, formal certification is required from AGIC. The tool has already been tested on a number of projects representing a range of infrastructure types, locations, phases and sizes. The rating tool scorecard can be downloaded free of charge at www.agic.net.au. The Energy and Carbon category The IS rating tool has an ‘Energy and Carbon’ category within the ‘Using Resources’ theme. As there are no regulatory initiatives specifically requiring infrastructure projects or assets to report on their energy and greenhouse gas (GHG) emissions at the project or asset level, this category seeks to drive best practice beyond regulatory requirements. For infrastructure, energy use and transport are responsible for more than 90 per cent of emissions, so it is particularly important to minimise the use of energy and promote the use of renewable energy. The category prioritises the avoidance of GHGs and minimising energy use through design, efficient operation and fuel substitution. It also recognises the use of GHG offsets. This category adopts the following principles: • Monitor and report on all energy use and GHG emissions at the project level – measure, verify and report on energy use, GHG emissions and management strategies at the project scale during all infrastructure life cycle stages. • Comprehensively identify and evaluate opportunities – work collaboratively with stakeholders to understand sources of energy use and GHG emissions, and develop effective management processes as part of a process of continual improvement. • Implement opportunities using the following hierarchy: * Avoidance – minimise the need for energy use and GHG emissions within the asset and associated systems through appropriate design; for example design out unnecessary activities that use energy or create GHG emissions. * Efficiency – adopt efficient construction and operational practices to minimise the energy and resource use associated with necessary activities. * Substitution – to meet remaining energy needs, prioritise low-emission and renewable energy sources. * Offsetting – residual GHG emissions may be offset with credible offsets that comply with the National Carbon Offset Standard. * Peak minimisation – minimise electricity drawn from transmission and distribution grids during times of peak system demand. AGIC’s research has found an industry-wide lack of data on energy and GHG emissions at the project level, making performance benchmarking against similar assets impractical at this time. Consequently, the credits within this category have a strong focus on energy and GHG management processes, and on improving the quality and availability of data on energy use and GHG at the project scale and across asset types, to support a shift towards performance benchmarking in later iterations of the tool.
