2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 2 CUMMINS AND 2021: A YEAR OF ACTION 2021 was dominated by challenges demanding action, from Cummins and our stakeholders. It will take all of us working together to address these broad and systemic issues, and Cummins is committed to taking a leadership role in these efforts. LEADING THE TRANSITION TO ZERO EMISSIONS Climate change is the existential crisis of our time. Climate-related catastrophes present a growing threat to the communities where we do business and to our plants, facilities, supply chain and customers around the world. Climate change is also the greatest threat to achieving our mission of making people’s lives better by powering a more prosperous world. The decarbonization of our economy is critical to our way of life, and our industry will play a key role in it. Our journey to zero emissions is also a growth opportunity for Cummins. We are confident in our ability to lead in bringing lower carbon technologies to commercial and industrial markets globally due to the unique capabilities Cummins has built over many years. Our company’s strategy to lead in this work is aligned with our sustainability goals, and we have a history of being a leader in sustainability. Over the last 20 years, we have reduced NOx (nitrogen oxides) and particulate matter emissions from today’s engines by over 90%. This new chapter of innovating for low carbon technology is another opportunity for us to deliver on our mission and provide solutions to our customers. Chairman and CEO Tom Linebarger announces to the Spanish media and invited guests that Cummins will build in Spain one of the largest manufacturing plants for electrolyzers in the world. CEO LETTER //
