Sainsbury’s said it saved 30 tonnes of paper this year by making its financial results available electronically to investors.

The Company revealed the strategy as part of its half-year results announced yesterday. It also said it had joined an organisation that promotes electronic shareholder communication called eTree, and will donate a sapling to the woodland conservation charity the Woodland Trust, for every shareholder registering with the service. “So far almost 5,000 shareholders have signed up, equivalent to approximately six acres of tree planting,” it said.

At the same time technology has played in role in its 123% profit for the period. The supermarket said its recovery was on track to meet its target of 2.5 billion pounds of total of extra sales by 2008. Total sales rose 8.3% to £9.6 billion.

It encountered particularly healthy grow online, where first-half sales grew by over 40% year on year while expansion targets to offer home delivery shopping to 85% of UK households.

Sainsbury’s product availability also contributed in a turnaround from the issues encountered in the run up to last Christmas that left shelves empty.

It said in it statement: “Focus in the supply chain has been on securing the benefits of the recent reorganisation and delivering underlying efficiencies. The reorganised depots are handling the increased volume compared to last year giving an improved service to stores with less resource.”

The company is in the middle of a three-year business transformation that saw it terminate its £1.7bn, seven-year deal outsourcing contract with Accenture and bring its IT back in-house in October of last year.
