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 product line to fulfill our requirements under AB-1305.

Carbon Offsets

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

Further, Braskem 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 Goals

We have set certain GHG emission goals as follows:

• Scope 1 and 2 GHG Emissions Intensity Target – Braskem has adopted a target to reduce companywide manufacturing Scope 1 and 2 GHG emission intensity by 15% by 2030. Braskem has adopted a goal to achieve carbon neutrality by 2050.

We utilize several reporting protocols and guidance documents to develop and compute our GHG emissions, targets and progress towards our targets, including: 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 targets and our progress towards our 2030 target, as well as the supporting GHG emissions data, can be found within the Industrial Decarbonization Program and the Strategic Pillars sections of the 2023 Annual Integrated Report on pages 37-38 and beginning on page 44, 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 HDPE. Based on this LCA, Braskem claims this product has a carbon footprint of -2.12 t CO2 q./t polymer. The LCA Study was conducted by ACV Brasil in 2023 (from cradle to Braskem factory gate). This study adheres to ISO 14040, ISO 14044, and ISO 14071 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. For more information, please see the comprehensive overview of this LCA or find more information at the I’m green product website.
