Memorandum Of Understanding (MOU) with Alcamare Post-Consumer Resins (PCR) made from Polyethylene (PE) and Polypropylene (PP) represent a viable option for fulfilling the commitments to use recycled materials made by global brand owners, and solutions for food products will play a crucial role. They are also a solution for complying with legislation in the United States and Mexico and focusing on providing incentives for the use of recycled materials in packaging. This is why, in collaboration with Alcamare, we signed a long-term cooperation agreement to develop food-grade recycled material. This collaboration agreement represents a significant advance in accessing a new select market for high-quality recycled materials that will complement the virgin products produced by Braskem Idesa. This sector will see a rapid growth rate, almost three times that of virgin resins. Recycled products require major investments in technology in order to be able to properly separate, wash, extrude and decontaminate plastic waste to reach the level of purity required. We expect that the use of these resins will help create attractive solutions for producers and consumers.

Short- and Long-Term Strategy Analysis: As part of our strategy, we comply with all regulations issued by the Department of the Environment and Natural Resources (SEMARNAT) and the Department of Energy (SENER), in addition to the Material and Energy Balance Methodology, monitoring all emissions stemming from our operations. We are also governed by a Global Development Policy that encompasses 7 Macro Sustainability goals, including climate change, operational efficiency, and actions and goals to help mitigate, reduce or capture GHG. The Greenhouse Gas Legal Framework we follow encompasses the following: • Climate Change Act, Regulations of the Climate Change Act for the National Emissions Registry (RENE), GHG Report for Annual Operating Cell (COA), GHG Calculation Methodologies, CO2 Emission Direct Measurement Methodology. • Annual GHG emissions reports and verification for the National Emissions Registry (RENE). • Emissions Trading System Program (SCE). 2. Emission Reduction Goals — 147 — Based on the Climate Change Act, the overall contribution to reducing GHG emissions from the chemical and petrochemical industry stands at 5% by 2030. As Braskem Idesa, our goal lies in: 1) Identifying projects to reduce, mitigate or capture CO2; 2) Driving energy efficiency in our operations; 3) Consolidating waste management; 4) Identifying renewable energies; 5) Participating in Emissions Trading; 6) Assessing the acquisition of an Energy Efficiency Certificate for the petrochemical complex. Additionally, Grupo Braskem has made a public global commitment through its operations in Brazil, the United States, Europe and Mexico to reduce GHG emissions by 15% before 2030, in addition to becoming carbon neutral by 2050. 3. Analysis of results vs. goals Regarding emissions by gas type in our operations, there was a decrease in 2021 compared to 2020 as a result of the following actions: 1) Equipment maintenance, the use of natural gas instead of ethane gas for energy generation, and operational efficiency stemming from the cutting-edge technology employed at the complex We measure our air emissions by type of gas, considering NOx, SOx, VOC, CO2, CH4, HFC, PM and other categories such as Cr. 2) Emission reduction targets 3)Analysis of the results in relation to objectives Braskem Idesa 2021 Sustainability Report ABOUT THIS REPORT LETTER FROM THE CEO CORPORATE PROFILE CORPORATE GOVERNANCE AND COMPLIANCE FINANCIAL PERFORMANCE ENVIRONMENTAL PERFORMANCE SOCIAL PERFORMANCE COVID-19 SUPPORT PROGRAMS CERTIFICATIONS AND AWARDS EARTH CHARTER MATERIALITY ALIGNMENT WITH GLOBAL SUSTAINABILITY STANDARDS GRI, SASB CONTENT INDEX AND VERIFICATION [102-12] [102-12] Code Topic Accounting metric Unit of measure Page / direct response RT-CH-120a.1 Air Quality Air emissions of the following pollutants: (1) NOx (excluding N2O), (2) SOx, (3) volatile organic compounds (VOCs), and (4) hazardous air pollutants (HAPs) Metric tons (t) — 148 — We measure our emissions by gas type, taking into consideration NOx, SOx, COV, CO2, CH4, HFC, PM and other categories (Cr).

(Braskem Idesa). Responsibilities, criteria and scope: The scope of our verification covered the results of "Braskem Idesa", corresponding to the period from January 1st to December 31st, 2021. Our mission is to issue impartial and objective opinions about the certainty, traceability and reliability of a sample of GRI and SASB Contents published in the Annual Sustainability Report ESG-2021. Our work considered as criteria: GRI Standards, in accordance with the Essential option, the SASB “Chemical” standards, and the International Standard on Assurance Engagements (ISAE) 3000, “Assurance Engagements Other Than Audits or Reviews of Historical Financial Information”. “Braskem Idesa” is responsible for the preparation of the information contained in the Annual Sustainability Report – ESG 2021, and that included in the scope of the verification, which implies, but is not limited to: the selection process of material topics, report of contents of the GRI Standards and SASB topics. Among the activities carried out during the verification process are listed: validation of information presented in previous reports, review of methodological compliance with the aforementioned standards, verification of qualitative and quantitative data through visual, documentary and public evidence and analysis of the quantitative data. Therefore, we can conclude that during the review of the sample of GRI and SASB content published in the Annual Sustainability Report - ESG 2021, we did not find any factor that makes us think that the data does not comply with certainty, traceability and reliability. Likewise, we did not identify any element that would lead us to consider that the methodological requirements were not met. An internal report of recommendations, exclusive to “Braskem Idesa”, is delivered separately, containing the areas of opportunity detected.
