The maximum distance for food or beverage raw materials to be harvested and produced for achieving the Materials and Resources Credit, Purchasing - Ongoing, is 100 miles (160 kilometers). This distance supports local economies and reduces the environmental impacts associated with transportation.
References: The LEED AP O+M Reference Guide outlines the criteria for sustainable purchasing, including the support of local food production within 100 miles of the project site1.
For the Materials and Resources Credit, Purchasing - Ongoing, food or beverage raw materials must be harvested and produced within a maximum distance of 100 miles (160 kilometers) from the project site. This criterion supports local agriculture and reduces the environmental impacts associated with transportation, contributing to a more sustainable supply chain.
References:This distance limitation is specified in the LEED AP Operations + Maintenance reference guide, particularly in the section on sustainable purchasing practices. The guide outlines how sourcing locally not only supports local economies but also minimizes carbon emissions related to transportation.
