Greenhouse Workbook and Calculator• A ‘whole of life’ approach– all major activities in the life cycle,• Design (excluded as not significant in its own right)• Construct• Operation• Maintenance• Decommissioning (excluded as rarely occurs)• Not Vehicle Emissions.– Other processes exist to calculate this• Assumes 50 year life in calculating maintenance and operations.• Defines materiality of inputs

Greenhouse Workbook and Calculator• Common methodology across jurisdictions – alignment with costestimating• Utilises common data sources for emission factors– National Greenhouse Account Factors– Will align with Australian life cycle (AusLCI) database• Will be further refined based on use and experience– Correlates actual and estimated data to validate• Breaks reporting down into scope 1,2,3 emissions.• Aim is to update it annually based on a number of criteria suchas experience and new materials or emission factors.• IT IS COMPREHENSIVE

Sustainability and Climate Change StrategyThe definition of sustainable transport is:“the ability to meet the needs of society to move freely, gainaccess, communicate, trade, and establish relationships withoutsacrificing other essential human or ecological values today or inthe future"This definition encompassed the following dimensions:• accessibility• travel time• reliability• safety• security• greenhouse gas emissions• impact on the environment and human well-being• resource use• impact on public revenues and expenditures

Sustainability and Climate Change Strategy• Meets Objective 3.4 Item51• Consistent with DTFGood Practice Guidelines– EnvironmentalProcurement (June 2009)• Consistent with Australiaand New ZealandGovernment Frameworkfor SustainableProcurement (2007)
