One such supplier is Volvo Group Australia. Appearing on Sky Business News in May, CEO Arne Knaben remarked that while no one could predict how a carbon tax would impact on the transport industry, Volvo was confident that it would not be disadvantaged. ? We?re not worried because we know our products are already way ahead and are setting the standard internationally,? he said. Volvo has pledged, for example, that its on-road and off-road trucks manufactured between 2009 and 2014 will emit 13 million less tonnes of carbon dioxide than the equivalent 2008 models.
