GM Environmental Progress

Leadership We committed to generate or source all electrical power for 350 operations in 59 countries with 100% renewable energy by 2050. We remain the only automaker to sign the Ceres Business for Innovative Climate & Energy Policy Climate Declaration stating that tackling climate change is an economic opportunity. GM is recognized as a world leader for climate change action by CDP, ranking on the Climate A List in 2016. GM has achieved perfect climate disclosure scores in the U.S. for the last three years from CDP, and earned a perfect score on climate change performance in 2014. We received a 2016, 2015, 2014 and 2013 EPA ENERGY STAR® Partner of the Year - Sustained Excellence award, the organization’s highest level of recognition for corporate energy management. EPA recognized us for raising climate change awareness. We were one of the first 13 companies to sign the White House American Business Act on Climate Pledge demonstrating ongoing commitment to climate action. The Solar Energy Industries Association named us a “Solar Champion” for significant impact on establishing a strong U.S. solar industry. Reducing Energy Use We reduced energy use at our global facilities by 28% on a per-vehicle-produced basis between 2005 and 2010. These savings reduced greenhouse gas emissions by 3.34M metric tons during that timeframe. We committed to reduce energy intensity from facilities by 20% by 2020 over a 2010 baseline. From 2010 to 2016, we reduced it 15%, despite severe winter climates. GM avoided $89M in energy costs through these conservation initiatives. We have 75 facilities meeting a voluntary energy-reduction challenge set by the U.S. EPA – more than any company worldwide. These facilities reduced energy by 25% on average, resulting in $237M in energy savings. We have received ENERGY STAR® certification at 14 of our facilities, such as our Lansing parts distribution center and Arizona IT Innovation Center. These buildings perform in the top 25th percentile of similar facilities nationwide. We reduced 20,000 metric tons of CO2 through energy efficiency at three buildings recognized in EPA’s ENERGY STAR® National Building Competition: Battle of the Buildings. We participate in U.S. Department of Energy’s Better Buildings, Better Plants program to achieve 25% or greater combined energy use reduction at 31 plants by 2018. The installation of 186,000 LED bulbs and fixtures is one of many steps helping us save $73M in energy costs in 2016. Our facilities around the world employ a variety of efficiency tactics: o Liuzhou, China used no heating system in winter, other than in the paint shop. Natural ventilation and harvested daylight make this one of the lowest energy per-unit plants in the world. o Bupyeong and Gunsan, Korea conducted paint shop energy conservation projects to save $820,000 annually. o Quito, Ecuador used solar panels to power LED lamps in outlying areas. o St. Catherine, Ontario replaced chillers with a water-cooling system using canal water from the adjacent St. Lawrence Seaway. o Gliwice, Poland made three heat recovery investments that, combined, save 9,140 MWh in annual energy use. Reducing Emissions By saving energy and increasing use of renewable energy sources, our global facilities achieved a 28% reduction in CO2 emissions on a per-vehicle- produced basis between 2005 and 2010. We committed to reduce carbon intensity from our facilities by 20% by 2020 over a 2010 baseline. From 2010 to 2016, we reduced it 15%. Since 1990, we decreased our manufacturing emissions by 60%. We joined EPA SmartWay Partnership to drive benchmarking of fuel use and emissions reduction by our freight shippers and carriers. Chevrolet met its voluntary commitment to reduce 8M metric tons of CO2 emissions from entering the atmosphere through its five-year community- based carbon reduction initiative. The brand retired the carbon credits to benefit the climate instead of using them to offset emissions of its vehicles or operations. o Investment projects promoted energy savings, renewable energy, responsible use of natural resources and conservation. o Chevrolet was the largest corporate buyer of voluntary carbon-reduction credits in the U.S. by volume for 2011, 2012, and 2013, as tracked by Forest Trends’ Ecosystem Marketplace. o We created a methodology enabling U.S. college campuses to earn money for their clean energy upgrades, a collaboration that won a Climate Leadership Award for Innovative Partnerships from the U.S. EPA Center for Corporate Climate Leadership. Updated August 2017 Renewable Energy We use 199.8MW of solar, landfill gas, hydro, and waste to energy at our facilities today, surpassing our 125MW renewable energy goal by 2020 four years early. Since our first renewable energy project in 1993, we’ve saved more than $80M. We now save about $5M annually. We are a founding member of the Rocky Mountain Institute’s Business Renewables Center and signatory to the WWF and WRI’s Corporate Renewable Energy Buyers' Principles designed to help utilities and renewable energy providers understand how they can make renewable energy investments easier and meet rising demand. o These NGOs brought together their expertise in transforming energy markets to create the Renewable Energy Buyers Alliance, which works to identify barriers to buying clean energy and develop solutions to meet growing demand. o GM is one of 60 multinational companies in REBA representing demand for renewable power. We made SEIA’s list of top corporate solar users in 2016, 2015, 2014, 2013 and 2012. We have more solar installations in the U.S. than any other automaker and have the second-highest percentage of solar usage among all commercial users. We house 56.5 MW of solar power at 26 facilities around the world; a footprint equivalent to the size of nearly 120 American football fields. o Our 1MW solar array on our distribution center in Rancho Cucamonga, Calif. was the first public solar project in the U.S. over 1MW when it began operating in the fall of 2006. It provides about half of the facility’s electricity. o We use solar to power 20% of our 400-plus EV charging EV charging stations and have nine facilities with solar EV charging. Two U.S. facilities use landfill gas as a source of energy. These installations generated a savings of $4M in 2016. Landfill gas use is: o 30% of the energy consumed at the Fort Wayne assembly plant o 41% at the Orion assembly plant. We increased landfill gas by 14MW at our Fort Wayne and Orion assembly plants in 2014, avoiding an additional 23,000 metric tons of CO2 per year. Toledo Transmission’s landfill gas operation was our first renewable energy installation, leading industry efforts for generating clean thermal or electric energy supporting such efforts as the EPA landfill methane outreach program. Over the course of the 20-year initiative, the site consumed more than 2M MMBTUs of landfill gas, equivalent to the carbon reduction of 445,000 metric tons. When the contract ended, we approved an energy efficiency project to eliminate steam from the site, further reducing our carbon footprint. Solid municipal waste from Metro Detroit is turned into process steam to heat and cool portions of our Detroit-Hamtramck assembly plant – GM’s top facility for renewable energy use at 58%. We are purchasing enough wind power to equal the electricity needs of 16 of our U.S. facilities, including business offices in Fort Worth and Austin, Texas, a major assembly and stamping complex in Arlington, Texas, and 13 parts warehouses. o When the contract begins in the first half of 2018, 6% of GM’s global energy use will be powered by renewable energy. We procured 34MW of wind to help power four of our Mexico facilities’ electricity needs. Our .98MW micro-hydro system at our St. Catherine’s plant in Canada eliminates chillers and natural gas-driven equipment. It harnesses the cooling energy of canal water to help reduce energy consumption and carbon emissions. A 74kW solar array and two 2kW wind turbines feed our Milford Data Center office’s circuit breaker panel, where five Chevrolet Volt batteries work in parallel to supply power to the building, delivering net-zero energy use annually. o The batteries can provide back-up power to the building for four hours during an outage and stores energy when it’s unneeded. Green Building We have nine LEED certified buildings: Joinville Engine in Brazil (Gold), GM China Advanced Technical Center (Silver), GM China Headquarters (Gold), Lansing Delta Township (Gold), our Enterprise Data Center (Gold), Korea Design Center (Gold), Baltimore Operations e-Motor Building (Silver), Milford Proving Ground's administration building, and Milford IT Data Center (Gold). o When it opened, the Lansing Delta Township building was the largest industrial project to be certified LEED. o A flywheel for battery-free backup power and in-row cooling reduces electricity at our Warren and Milford data centers. o Joinville Engine is the first automotive plant in South America to become LEED Gold certified. It generates electricity from sunlight, heats water using solar power, and reuses water through reverse osmosis. We earned ISO 50001 certification for energy management at nine facilities throughout Europe, Asia and South America. We follow LEED practices in any new construction projects or renovations regardless of whether we apply for certification. All of our North American construction sites adhere to GM Green Construction practices. Updated August 2017 Landfill-Free Facilities We aspire to become the first automotive company in the world to achieve zero-waste manufacturing. We have a total of 152 landfill-free facilities worldwide that reuse, recycle, or convert to energy all waste from daily operations. No other automaker has as many facilities contributing zero waste to landfill.
