California Voluntary Carbon Markets Disclosure (AB-1305)

The Voluntary Carbon Market Disclosures Act, Assembly Bill No. 1305 (“AB-1305”), requires entities doing business in California to disclose specified information regarding the marketing, sale, purchase, or use of certain voluntary carbon offsets under Sections 44475 and 44475.1. In addition, AB-1305 requires disclosure of specified information regarding claims of net zero achievement, carbon neutrality, or significant greenhouse gas (“GHG”) emissions reductions under Section 44475.2. This disclosure is intended to work in conjunction with reports found on our website under the ESG tab and I’m green^TM bio-based product information found on our website under the I’m green bio-based product line to fulfill our requirements under AB-1305.

Carbon Offsets

Braskem America, Inc, its subsidiaries and affiliates (“Braskem America”) are not marketing or selling voluntary carbon offsets, as defined in Section 44475, within the State of California.

Further, Braskem America has not relied on the purchase or use of voluntary carbon offsets in making any public claims regarding the achievement of net zero emissions, carbon neutrality or significant reductions in carbon dioxide or greenhouse gas emissions.

Claims of Net Zero Achievement, Carbon Neutrality, or Significant GHG Emissions Reductions

GHG Emission Reduction Objectives

We have set certain GHG emission objectives as follows:

• Scope 1 and 2 GHG Emissions Intensity Objective – Braskem S/A ("Braskem"), parent company of Braskem America, has adopted an objective to reduce companywide manufacturing Scopes 1 and 2 GHG emission intensity by 15% by 2030. Braskem has adopted an objective to achieve carbon neutrality by 2050 (Scopes 1 and 2).

We utilize several reporting protocols and guidance documents to develop and compute our GHG emissions, plan and progress towards our objectives, including: GHG Protocol Program, GRI (Global Reporting Initiative), SASB (Sustainability Accounting Board Standards), and IIRC (International Integrated Reporting Council) global sustainability performance standards.

Additional information on Braskem’s GHG emissions plan and our progress towards our 2030 objective, as well as the supporting GHG emissions data, can be found within the Industrial Decarbonization Program and the Strategic Pillars sections of the 2024 Annual Integrated Report on pages 38-40 and beginning on page 48, respectively.

As stated in the latest Annual Integrated Report, Braskem's GHG inventory includes 100% of industrial operations under the company's operational control, is audited by an independent third party, and has a gold seal by the Brazilian GHG Protocol Program.

Product-Specific Carbon Footprint Claims

We have conducted a Life Cycle Assessment (LCA) on our I’m green^TM bio-based product family, which includes HDPE, LDPE, LLDPE, EVA, and PE Wax. Based on this LCA, Braskem claims the product carbon footprint of each product, which are -2.12 t CO2 eq/t HDPE, fo example. The LCA Study for PE grades was conducted by ACV Brazil in 2023 (from cradle to Braskem's factory gate). This study adheres to ISO 14040 and ISO 14044 standards, using the EF 3.1 Life Cycle Impact Assessment (LCA) method, and this LCA study was subject to a critical review process performed by KPMG according to ISO 14071 standard. For more information, please see the comprehensive overview of this LCA or find more information at the I’m green bio-based product website.

 

Climate Related Financial Risk (SB 261)

SB 261, the climcate-Related Financial Risk Act, is the California law requiring companies doing business in the state to publicly disclose climate-related financial risks - both physical (e.g., extreme weather) and transition risks (e.g., regulatory or market changes) - though biennial reports aligned with the Task Force on Climate-related Financial Disclosures ("TCFD") framework. The law aims to improve transparency and risk management, with enforcement by the California Air Resources Board (CARB).

 

 

 

Consistent with CARB's minimum requirements, the table below outlines where the required information is located within Braskem's 2024 Integrated Report and Transistion Plan , noting that some disclosures are only partally available.

Braskem has recently disclosed its transition plan to the market aligned with the Transition Plan Task Force (TPT), providing detailed information on climate-related risks and opportunities. Furthermore, in accordance with CVM Resolution 193 in Brazil, which requires the publication of sustainability reports aligned with IFRS S1 and S2 starting from the 2026 fiscal year, Braskem is preparing to release its first report aligned with these standards, reinforcing transparency and adherence to leading market practices.
