Kirei, a provider of sustainable acoustic design materials, announced that it is now a Certified B Corporation. This certification recognizes that Kirei meets high standards of social and environmental performance, accountability and transparency, reinforcing its long-standing values of sustainability, innovation and responsibility.
The B Corp Certification process is administered by B Lab, a nonprofit network aiming to transform the global economy to benefit all people, communities and the planet. To achieve certification, Kirei underwent a rigorous review of its impact on workers, customers, communities and the environment, and made a legal commitment to stakeholder governance.
B Corp Certification is not a one-time achievement but part of a framework for continuous improvement. To maintain certification, companies must recertify every three years, demonstrating they continue to meet evolving standards. With its first certification, Kirei joins its parent company, Carnegie — a Certified B Corporation since 2014 and recently recertified — as part of a global community of businesses using business as a force for good.
“Kirei’s B Corp certification marks a defining moment for the team and a realization of the vision originally set forth by John Stein, Kirei’s founder,” said Carnegie CEO Gordon Boggis. “By joining forces with Carnegie, we are setting a new standard for positive impact in the design industry — delivering products and solutions that combine performance, sustainability and purpose, while inspiring architects and designers to create spaces that truly make a difference.”
Since 2002, Kirei has transformed recycled materials into architectural elements that are elegant, functional and easy to specify. Its acoustic products are low-VOC and Class A fire-rated, with Health Product Declarations to help earn LEED and Well Building credits.
Kirei is now one of more than 10,000 Certified B Corporations across over 150 industries and 80 countries.
