vicroadsThe Transport Authorities Greenhouse Group (TAGG) developed the Greenhouse Gas Assessment Workbook to provide road designers, builders, managers and operators with a means of consistently estimating greenhouse gas (GHG) emissions at the key stages of construction, operation and maintenance.

Edge Environment partnered with Parsons Brinkenhoff to work with Australian and New Zealand authorities to fulfill their objective of establishing a common approach to estimating the greenhouse gas emissions from road projects.

The Workbook is designed to enable a consistent methodology for the assessment of significant emission sources, estimation of GHG emissions and to provide a better understanding of how GHG emissions can be reduced.
