2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 3 We used our lessons learned during the pandemic to create enhanced ways of working for Cummins employees. We are steadfast in our commitment to building a dynamic workplace where all employees are inspired and encouraged to achieve their full potential. We recognize that how we work in the future will be different from how we have worked in the past. Through enhanced ways of working that are more flexible, agile and inclusive, we can increase the productivity of our teams and create a better environment for our employees. LEADING TO SERVE OUR STAKEHOLDERS Our long-standing commitment to our stakeholders—our communities, customers, employees, partners and shareholders— remains a top priority. Aligned with our stakeholder model, we believe that each stakeholder in a company is served best by supporting every stakeholder. At Cummins, we do this by living our core values inside and outside of the workplace. Our success depends on our ability to create a diverse, equitable and inclusive culture. Diversity, equity and inclusion (DE&I) is a Only Cummins can power our customers’ success through this transition with our growing portfolio of diesel, natural gas, propane, hydrogen, fuel cell and battery system solutions. LEADING TO CREATE A GREAT WORK ENVIRONMENT Despite our desire for the pandemic to end, COVID-19 continued to rage on. In 2021, we focused on encouraging our employees to get COVID-19 vaccinations to keep everyone as safe and healthy as possible. We started by launching a global employee survey on vaccine interest, questions and concerns. We used those responses to launch a global vaccine education campaign where employees could get answers on vaccine topics from knowledgeable sources they trust. As vaccines became available, we delivered more than 45,000 vaccine shots around the world to protect Cummins employees, contractors and their families, sponsoring vaccination clinics from India to Indiana. In the U.S., we also launched a vaccine incentive program. » A global strategic partnership with Daimler to provide medium-duty powertrain systems for Daimler Trucks and Buses. » An agreement with Iberdrola, one of the world’s largest energy companies, on large-scale hydrogen production projects in Spain and Portugal. » A Letter of Intent to acquire 50% equity interest in Momentum Fuel Technologies from Rush Enterprises to produce Cummins- branded natural gas fuel delivery systems for the commercial vehicle market in North America. » An agreement with Sion Power Corporation to design and supply battery cells based on their proprietary lithium metal technology for commercial vehicle applications; and » The formation of a 50:50 joint venture with Sinopec to form Cummins Enze, which will accelerate the affordability and availability of green hydrogen in China. In 2021, we took several steps to address climate change in critical parts of the economy:  We announced a new 15-liter engine platform for heavy duty trucks that will begin with a natural gas version and later be available in a variety of fuels from diesel to hydrogen. This platform will offer leading power and performance while meeting more stringent emissions regulations.  Cummins passed more than 2,000 fuel cells deployed and built a new fuel cell systems production facility in Herten, Germany.
