Large enterprise supply chain customers are also
developing GSCM practices. The Warehouse, New Zealand's
Wal-Mart, claims to have reduced its carbon footprint by 16
percent, largely through transport efficiencies, and to have
reduced waste to landfill in recent years by 20 percent. The
retailer annually grades the environmental performance of its
suppliers and in 2008-2009 carried out on-site grading at 105
factories. It has announced an intention to stop purchasing
from suppliers that fail to meet its environmental standards.
