To reduce the environmental harm from materials purchased, used, and disposed of in the operations within buildings.
Have in place an Environmentally Preferable Purchasing (EPP) policy that includes, at a minimum, product purchasing policies for the building and site addressing the requirements of MR Credit 1, Sustainable Purchasing: Ongoing Consumables. This policy must adhere to the LEED for Existing Buildings: O&M policy model (see Introduction). At a minimum, the policy must cover those product purchases that are within the building and site management’s control.
Additionally, extend the EPP policy to include product purchasing policies for the building and site addressing the requirements of at least one of the credits listed below. This extended policy must also adhere to the LEED for Existing Buildings: O&M policy model and specifically address the goal, scope and performance metric for the respective credit:
- MR Credit 2: Sustainable Purchasing—Durable Goods
- MR Credit 3: Sustainable Purchasing—Facility Alterations and Additions
- MR Credit 4: Toxic Material Source Reduction—Reduced Mercury in Lamps
This prerequisite requires only policies, not ongoing actual sustainable performance.
