Sorona® Could Help Your Next Project Become LEED® Certified


Developed by the U.S. Green Building Council in 2000, Leadership in Energy and Environmental Design (LEED®) provides a framework for identifying, implementing, and measuring green building practices.

Buildings are LEED® certified based on rating systems measuring performance in key areas affecting human and environmental health. The main LEED® categories are Efficiency, Water Savings, Sustainable Site Development, Materials Selection, and Indoor Environmental Quality.

Scoring Points for Better Building Practices

The LEED® rating system awards points based on a project’s potential environmental impacts and human benefits. Points can be earned across five major categories and additional points may be credited for Innovation in Design and Regional Priority. There are four tiers of certification: Certified, Silver, Gold, and Platinum.

Four Different Ways to Earn LEED® Points with Sorona®

Materials produced with Sorona® can help your next building project become LEED® certified in two of the major LEED® categories (Materials and Resources and Indoor Environmental Quality). Points may potentially also be awarded based on Innovation in Design and Regional Priority depending on project specifics.

Materials and Resources

(MR Credit 6: Rapidly-Renewable Materials  / 1 Point Available)

Sorona® polymer contains 37% renewably sourced, plant-based material by weight. If a building project employs a minimum of 5% rapidly-renewable material (defined as plant-derived and typically harvested within a 10-year cycle) that project may earn points towards becoming LEED® certified.  

Indoor Environmental Quality

(IEQ Credit 4.3: Low-Emitting Materials / 1 Point Available)

Carpeting created with Sorona® fiber can help your project become LEED® certified. Sorona® is a low-VOC-emitting material, so carpeting produced with Sorona® makes for cleaner, more healthful indoor air. To qualify for the Indoor Environmental Quality (IEQ) credit, a carpeting system must meet or exceed the requirements of the Carpet and Rug Institute’s Green Label Indoor Air Quality Testing Program. For specific requirements, please visit The Carpet and Rug Institute.

Regional Materials

(MR Credit 5: Regional Materials  / 1-to-2 Points Available)

Projects containing a minimum of 20% locally-manufactured products and materials may qualify to be LEED® certified. So if your building is going up within a 500-mile radius of where Sorona® is manufactured - Kinston, North Carolina and Yuhua, China - Sorona® may help you earn up to two Regional Priority points under LEED® 2009.

Innovation in Design

Under certain circumstances, Sorona® polymer may also help your project earn points towards becoming LEED® certified based on Innovation in Design. For more information on whether your building meets LEED® certification rating requirements in any of the above areas, please visit the U.S. Green Building Council.

A Commitment to Sustainability and Safety

At DuPont our scientists are always looking for ways to make human beings safer and reduce the environmental footprint of new construction and renovations. Renewably Sourced™, low-VOC-emitting DuPont™ Sorona® helps accomplish both objectives and may help your next project become LEED® certified.

Sorona® contains 37% annually renewable plant based ingredients by weight (28% biobased carbon)
