* Every aspect of the design and construction of Woolworths' Midrand distribution centre was subjected to social and environmental perspectives to ensure it had the least possible impact on the surrounding environment and community. To locate the best site for the centre a "gravity study" was undertaken to calculate which site would be the best to ensure Woolworths' trucks needed to travel the shortest possible distance to get there. * Woolworths has had the carbon footprint of its head-office buildings, distribution centres and company stores calculated independently by Global Carbon Exchange.
