IBM steps up the green supply chain pressure

Interesting piece in the Harvard Business Review blogs about how IBM is stepping up the pressure on its suppliers.

IBM wants its suppliers to do four things:

1. Define and deploy an environmental management systems (EMS).
2. Measure existing environmental impacts and establish goals to improve performance.
3. Publicly disclose their metrics and results.
4. "Cascade" these requirements to any suppliers that are material to IBM's products.

Separately, another Harvard Business Review post discusses a new tool for understanding sustainability drivers.
