2021 SUSTAINABILITY PROGRESS REPORT | Cummins Inc. 22 YEAR CUMULATIVE EMISSION REDUCTION (in metric tons of CO 2 ) 2014 Baseline 2015 2.3 million 2016 5.2 million 2017 8.6 million 2018 12.9 million 2019 17.4 million 2020 22.1 million 2021 26.8 million 2030 GOAL 55 million PROGRESS ON GOAL PARTNERING WITH CUSTOMERS TO REDUCE EMISSIONS This table looks at progress on Cummins’ goal to partner with customers to reduce Scope 3 emissions from products in the field. ENVIRONMENTAL PROGRESS // DOING OUR PART BY THE NUMBERS 9 BILLION Customer savings in dollars from products in use fuel economy projects since environmental sustainability goals were established in 2014. Projects with customers also saved 3 billion gallons of fuel and avoided 27 million metric tons of CO 2 . Since first surpassing the company’s 2020 goal in 2018, Cummins has continued partnering with customers to implement fuel savings projects and is on track to exceed its 2030 goal. In 2021, an additional 50 customer projects were completed, bringing the cumulative total since 2014 to 700. The PLANET 2050 goal is now formally expressed as a cumulative carbon dioxide (CO 2 ) reduction since a baseline year of 2014, rather than the annual run rate achieved. Cummins and its customer partnerships achieved big gains in the early years of this initiative as projects with high returns were identified and completed. As products have become more and more efficient, Cummins is now tackling increasingly complex projects to achieve fuel economy savings, including route optimization and the introduction of lower emissions fuels. Customers continue to show interest and dedication to improving their product environmental footprint, and Cummins is dedicated to continuing to partner to help customers achieve their sustainability goals. CUMMINS ON PACE TO ACHIEVE EMISSION REDUCTION GOAL PARTNERING WITH CUSTOMERS From optimizing products for specific market segments, to the use of sophisticated digital tools to assist in the truck specification process, to the ability to customize electronic engine settings and parameters, Cummins helps customers reduce their carbon footprint throughout the life of the company’s products. GOAL 3: Partner with customers to reduce Scope 3 GHG emissions by 55 million metric tons of carbon dioxide (CO 2 ).
