Question
LEED considers products to be environmentally preferable materials when they are
A. materials with more life-cycle impact
B. cost effective
C. transported by air rather than rail
D. locally extracted, manufactured and purchased
Answer
D. locally extracted, manufactured and purchased
Explanation
LEED considers products to be environmentally preferable when they are locally extracted, manufactured, and purchased. This is because local sourcing reduces the environmental impact associated with transportation, supports local economies, and can often ensure that the materials are suitable for the local climate and conditions.

According to LEED standards, environmentally preferable materials are those that are locally extracted, manufactured, and purchased. There are several reasons why LEED considers local sourcing to be an important factor:
- Reduced transportation emissions: When materials are sourced locally, it minimizes the distance they need to be transported, thereby reducing greenhouse gas emissions associated with shipping. This aligns with LEED’s goal of promoting sustainable practices and reducing the environmental impact of buildings.
- Support for local economies: By prioritizing locally sourced materials, LEED encourages supporting local businesses and strengthening regional economies. This can help foster sustainable communities and reduce the overall environmental footprint of a project.
- Increased transparency and accountability: Local sourcing allows for better transparency and accountability in the supply chain. It becomes easier to verify the extraction and manufacturing processes, ensuring they adhere to sustainable practices and meet LEED requirements.
The other options are incorrect because:
A. Materials with more life-cycle impact are not considered environmentally preferable, as they have a greater negative impact on the environment throughout their production, use, and disposal.
B. While cost-effectiveness is important, it is not the primary factor in determining if a material is environmentally preferable according to LEED standards.
C. Transportation by air is more carbon-intensive than rail, making it a less environmentally friendly option. LEED prioritizes minimizing transportation emissions through local sourcing.
In summary, LEED considers products to be environmentally preferable materials when they are locally extracted, manufactured, and purchased, as this reduces transportation emissions, supports local economies, and promotes transparency and accountability in the supply chain.
