In LEED, why is it important to use locally sourced materials?

Using locally sourced materials is crucial in the context of LEED because it encompasses multiple beneficial impacts on sustainability and community health. Local sourcing plays a significant role in reducing transportation distances, which contributes to lower transportation costs and diminished greenhouse gas emissions associated with longer-distance transport of materials. This reduction in transportation not only helps in lowering project costs but also in decreasing the project's overall environmental footprint.

Additionally, sourcing materials locally bolsters the local economy by supporting nearby suppliers and craftsmen. When projects prioritize local resources, they stimulate economic activity in the region by creating jobs and fostering community development.

Moreover, minimizing environmental impact is essential in sustainable design practices. Local sourcing leads to a smaller carbon footprint, helping to conserve energy and reduce pollution associated with the manufacturing and transportation phases of building materials. The collective benefits of economic support, cost reduction, and environmental conservation align perfectly with LEED’s goals of promoting sustainable building practices.

Thus, the combination of these factors makes the choice to use locally sourced materials a critical component of LEED certification criteria, highlighting a comprehensive approach to sustainability that addresses economic, environmental, and community aspects.
