More than three quarters of participants in the grocery supply chain are using or considering using combined deliveries with other companies, according to new research. An IGD survey of 40 leading suppliers and grocery retailers found 77.5% of them were using, developing or considering collaboration to make distribution more environmentally friendly. And collaborative distribution schemes were already being used or developed in 60% of businesses. But more needed to be done to meet industry targets, said Alastair Sykes, IGD president and CEO of Nestlé UK & Ireland. "Competition alone will not meet the sustainability challenge; greater collaboration will be essential." The survey follows calls from Asda strategy and logistics director Douglas Gurr in June for companies to combine deliveries to achieve the government's target of a 20% cut in the social and environmental costs of food transport by 2012.
