As a leading manufacturer and distributor in the insulation industry, we understand our role in environmental preservation. A recent study by Ron King, published by the National Insulation Association (NIA), reinforced what many in our industry already know: mechanical insulation systems are crucial for clients aiming to reduce their carbon footprint. According to the study, inadequate insulation could lead to over 751 million metric tons of extra carbon emissions over an 11-year period. We are keenly aware of the potential environmental impact of insufficient insulation and are committed to minimizing this loss wherever possible. This commitment extends to supporting our customers in pursuing energy savings goals and implementing green building practices. Whether providing eco-friendly and energy-efficient insulation materials to meet LEED building certification standards or assisting with insulation credits, our team is dedicated to advocating for and achieving reduced carbon footprints in all our projects. Our efforts in 2020 alone allowed SPI to save more energy than that produced by all the cars in Boston, MA, all the vehicles in Rhode Island, or all the homes in Pittsburgh, PA.
However, our sense of responsibility goes beyond assisting clients with their energy conservation goals. We take care to stock products that align with our sustainability values and work closely with vendors who share our dedication to environmental stewardship. We are proud to collaborate with eco-conscious brands that amplify our impact in these areas. Additionally, many of our best-selling materials, including mineral wool and fiberglass, are made from recycled materials. These materials last for years without needing replacement, reducing their environmental impact and emphasizing our dedication to sustainable practices.
Our commitment to sustainability is not limited to our products and services; it extends into all of the most important aspects of our operations. Alongside offering sustainable materials, we prioritize efficiency in critical areas such as renewable energy adoption, operational sustainability, and waste reduction. Recognizing the value of reducing carbon emissions, we assist our clients in transitioning their insulation systems to more efficient and renewable materials, acknowledging that the recent Lazard report on the levelized cost of energy highlights energy efficiency as one of the most cost-competitive renewable energy solutions. We implement operational sustainability practices within our own locations and warehouses, striving to reduce waste throughout our logistics process by understanding customer needs and providing exceptional service. This allows us to minimize wasted space on freight shipments and aim to reduce overall shipment volume. Our attention to detail means that our warehouse operations consume less than 0.5% of the energy saved annually by our products.
As leaders in our industry, we understand our responsibility to support and protect our environment. We are proud to drive corporate climate-friendly initiatives and invest in sustainable development goals. Transparency is paramount; we advocate for clear and open sustainability reporting, sharing information about our efforts whenever possible. We aim to build sustainable partnerships that enable us to continue this vital work. If you're interested in improving energy efficiency, we're here to help. Contact us today to learn more.
