Establishes a database for environmental performance of all new vehicles sold in Australia weighing 3.5 tons or less: the Green Vehicle Guide (GVG). Provides model-specific fuel consumption and CO2 emissions data, based on data provided by manufacturers for each vehicle as part of the certification process. In 2015, the GVG underwent an upgrade to place a stronger focus on CO2 emissions and improve the ability of consumers to calculate annual fuel costs and CO2 emissions of individual models.
