DOW | 2021 ESG REPORT | 4 Dear Stakeholders, This year Dow marks its 125th anniversary. While we celebrate our rich heritage, we are also imagining how we can build a better, more sustainable and equitable future. As a science and technology company, we eagerly take on the responsibility for finding answers to the most pressing challenges of our time. This is central to our purpose as a company. It is central to our growth strategy. And it is central to driving best-in-class performance and accountability. Throughout this report, you will see how we are using our Environmental, Social and Governance (ESG) approach as a catalyst for innovation and collaboration to create new products, new business models and new ways to build value for our customers, our people, our communities and our stockholders. It is clear to us that sustainable innovation and profitable growth are not mutually exclusive, but rather mutually dependent. It is also clear that our intentional focus on collaboration and inclusion helps us better navigate challenges and grow our impact to deliver positive change for the world. We have crafted a portfolio that is well-positioned to meet the increasing needs of our customers and consumers who are demanding more circular and sustainable products around the world. We have a clear, science-based, disciplined and affordable path to carbon neutrality, even while we continue to grow our capacity and improve transparency and accountability on all our sustainability efforts. To advance our efforts, we are continuing to build a strong and inclusive culture, which is evidenced by our recognition as the only materials science company to earn a place on the Great Place to Work and Fortune 100 Best Companies to Work For list. At the same time, we know that best-in-class governance means continuous improvement, and we are committed to challenging ourselves and raising the bar by further enhancing diversity at all levels throughout the company. Here are some of the important ways we advanced our ESG agenda in 2021: • We are executing on our plan to decarbonize our business and grow value. To reach our 2030 and 2050 carbon emissions targets we have a plan to replace end-of-life assets with new, more carbon-efficient technologies. In 2021, for example, we announced plans to build the world’s first net- zero carbon emissions, integrated ethylene cracker and derivatives site in Fort Saskatchewan, Alberta. In addition, we outlined a detailed roadmap to reduce current CO 2 emissions from our operations in Terneuzen, the Netherlands, by more than 40% by 2030. We are one of the top 20 global corporations using renewable, clean energy, and we expanded our access to renewable energy to more than 900 megawatts. We also continue to invest in next- generation, carbon-efficient technologies such as e-cracking, fluidized catalytic dehydrogenation (FCDh) technology and ethane dehydrogenation (EDH). • We are accelerating our sustainability investments to enable design for recyclability and more circular plastics through mechanical and advanced recycling. To advance our 2030 targets to Stop the Waste and Close the Loop, our team is working across our value chains to enable packaging design with recyclability in mind. We also have our own product line of recycled-content resins under the brand name REVOLOOP™. Today, 85% of our products sold into packaging applications are reusable or recyclable. As we continue down our path to enable more recyclability and keep plastic waste out of the environment, we are scaling supply partnerships with companies such as Mura Technology and Fuenix to produce circular feedstocks from advanced recycling processes. In fact, we are committed to delivering circular polymers from advanced recycling by the end of 2022. We also are investing in collaborative actions to minimize and manage plastic waste through partnerships such as the Alliance to End Plastic Waste.
