ENERGY, FUEL ECONOMY & EMISSIONS REVOLUTIONIZING RESOURCE INDUSTRIES Our technology-dependent world relies on mined minerals — especially when it comes to powering emerging renewable energy solutions. In 2021, we focused on supporting sustainable mining with new battery electric and automated equipment options. We continue to evolve our portfolio through partnerships and acquisitions. FIRST OF ITS KIND IN UNDERGROUND MINING Recognizing the demand for a battery electric vehicle in deep, difficult-to-ventilate underground mines, we have introduced a diesel-electric underground loader, along with the forward-looking R1700 XE — a high productivity, zero exhaust emissions loader with the industry’s only onboard battery and a portable equipment charger. It will complement a first-of-its-kind battery electric, zero exhaust emissions underground truck to provide a fully electric underground load and haul solution. FUEL EFFICIENT LARGE DOZERS The D11 XE large dozer is our highest producing, most fuel-efficient Cat dozer ever. Equipped with an electric drive powertrain, it reduces fuel consumption by up to 25% with a machine lifespan up to 20% longer. We also updated our D10 series dozers, which now use 4% less fuel while offering a 3% boost in productivity. REDUCED EMISSIONS LARGE WHEEL LOADERS The Cat 992 Large Wheel Loader has set the standard in its size class for more than 50 years. In 2021, we raised the bar with our new 992, which has been demonstrated to produce up to 32% less emissions than its 992K counterpart. 26CATERPILLAR 2021 SUSTAINABILITY REPORT
