Braskem America Awarded International Sustainability & Carbon Certification PLUS (ISCC PLUS) for all U.S. Production Facilities

Braskem (B3: BRKM3, BRKM5, and BRKM6; NYSE: BAK; LATIBEX: XBRK) the largest polyolefins producer in the Americas, as well as a market leader and pioneer producer of biopolymers on an industrial scale, announced that Braskem America has received International Sustainability & Carbon PLUS (ISCC PLUS) certification for all five of its polypropylene (PP) manufacturing facilities in the United States.

Mark Nikolich, Chief Executive Officer of Braskem America, commented, "Achieving ISCC PLUS certifications for Braskem U.S. production facilities reflects a major milestone around our continued progress in advancing our vision for a carbon-neutral circular economy. ISCC PLUS certification is a critical step in Braskem's transition to increase the use of both recycled and renewable feedstocks and the production of more sustainable PP for our clients utilizing the mass balance chain of custody."

ISCC is a globally leading certification system that provides transparency and traceability for sustainable feedstocks along the entire supply chain and is already well-recognized by many stakeholders in the plastics industry. For companies using the mass balance approach, ISCC PLUS certification verifies that the mass balance accounting follows predefined and transparent rules. ISCC PLUS certification also provides traceability along the supply chain and verifies that all feedstocks meet environmental and social standards.

Certification of Braskem's U.S. manufacturing sites demonstrates the company's implementation of robust processes that verify mass balance accounting compliant with the ISCC PLUS standard. Braskem America will now be able to accelerate the production and sale of certified circular and bio-attributed PP solutions to its clients.

Braskem America's U.S. production facilities awarded ISCC PLUS certification include:

• Marcus Hook, Pennsylvania
• Kenova, West Virginia
• LaPorte, Texas
• Oyster Creek, Texas
• Seadrift, Texas

Braskem first received ISCC PLUS trading certification in 2021 which first allowed the company to sell its sustainable products to the market. Braskem has clearly stated targets for growing the company's recycled content product portfolio to sales of 300,000 tons by 2025 and 1 million tons by 2030. Braskem's transition to a circular economy is deeply rooted in mechanical and advanced recycling solutions. By engaging and investing in partnership with other value-chain players Braskem is strengthening mechanical and advanced recycling, overcoming barriers, and ensuring the increased production of high-quality recycled material. All these initiatives are aligned with Braskem's feedstock diversification strategy and its macro goals of expanding the circular economy concept in the plastics chain and becoming a carbon-neutral company by 2050.
