IBM announced that it will require its 28,000 suppliers in more than 90 countries to install management systems to gather data on their energy use, greenhouse gas emissions and waste and recycling.
Those companies in turn must ask their subcontractors to do the same if their products or services end up as a significant part of I.B.M.'s $40 billion global supply chain. The suppliers must also set environmental goals and make public their progress in meeting those objectives.
"We will be amongst the first, if not the first, with these broad-based markers on our supply base and we're going to have to spend an appropriate amount of time and money to help our suppliers do what we're asking them to do," John Paterson, vice president for I.B.M.'s global supply and chief procurement officer, said in a telephone interview from Hong Kong.
