This development is the fruit of a campaign by TASS to get biodiesel in more school buses. The campaign was launched at a workshop in October which brought together experts from Shell, ASB Biodiesel, Green School Bali, WWF as well as THS and sustainability practitioners from several other international schools. Subsequent collaboration between THS and TASS culminated in the recent decision by JBC and THS to use biodiesel to reduce the carbon emissions from its bus service.
