NSSGA members recognize that the Earth's resources, upon which all life depends, are finite, and that wise environmental stewardship is necessary today to preserve the potential for a quality life for future generations. NSSGA members believe that wise environmental stewardship is good business, and good for business.


NSSGA members invest in extensive dust control systems to protect the environment. NSSGA member products, such as crushed stone, are used to control air emissions from power plants and other industrial sources.


NSSGA members work diligently to conserve and protect valuable water resources both for human consumption and aquatic habitats. NSSGA products are used in water supply and wastewater treatment, as well as in public works infrastructure.


The removal of aggregates temporarily disturbs the landscape. However, once the materials have been extracted, NSSGA members reclaim the land into wetlands, wildlife habitats, parks and many other beneficial purposes.

NSSGA and Wildlife Habitat Council Renew Partnership

The National Stone, Sand & Gravel Association and Wildlife Habitat Council renewed on Sept. 14 a shared commitment to the enhancement and restoration of wildlife habitats at aggregates operations across the U.S.

Michael W. Johnson, NSSGA president and CEO, and Margaret O’Gorman, Wildlife Habitat Council president, signed a memorandum of understanding that outlines a shared desire to advance voluntary programs that allow aggregates operations to achieve their business goals and provide environmental benefits to the local community.


NSSGA members identify sustainability as a business approach that integrates environmental stewardship, social responsibility and economic prosperity to ensure the long-term supply of aggregate materials to society. NSSGA members sustain the communities in which they operate by providing raw materials as natural building blocks for quality of life. NSSGA members maintain adequate aggregates resources in locations that minimize the life cycle impacts of the resource’s extraction, delivery and use. NSSGA members believe in being good neighbors by creating wildlife habitats and supporting local schools and other community institutions and efforts.

GHG Emissions Calculator

This protocol is intended to assist NSSGA member aggregate producers and pulverized mineral producers calculate emissions of greenhouse gases (GHG) in an accurate, consistent and verifiable manner. The GHG inventories provide emission baselines and are a useful tool for evaluating options for reducing GHG emissions. The GHG emissions data compiled based on this inventory protocol can help NSSGA member companies inform stockholders and public stakeholders concerning GHG emissions and emission reduction programs.
