Appendix Metric / Disclosure / Topic Source(s) Methodology / Definition To calculate scrappage age of vehicles in a region, you sum up annual vehicle sales from the most current year U.S. Department of Transportation, European going back until the sum equals the current vehicle parc size. In order to be conservative, and normalize our figure Automobile Manufacturers Association, based on recent vehicle sales trends in each region, we divided total vehicle parc by average vehicles sales in the International Organization of Motor Vehicle respective regions for 2019 and 2020 (latest available data). This resulted in a scrappage age of 17 years and Manufacturers, Association Auxiliaire De 200,000 miles in the U.S. and 20 years and 150,000 miles for Europe. For simplicity, China assumed to have similar Vehicle useful life L'Automobile useful life to Europe of approximately 20 years and 150,000 miles. Figures based on estimated EPA range and usable battery capacity disclosures by OEMs for each model. Where EPA range did not exist WLTP was used to determine a theoretical EPA range based on average EPA to WLTP Energy Efficiency EPA range in miles/kWh U.S. EPA, OEM data ranges for other EVs. % of U.S. Vehicle Fleet chart figures calculated using vehicle parc figures from U.S. Department of Transportation. % of U.S. Vehicle Emissions chart figures estimated using vehicle parc, fuel economy and VMT data from U.S. Department of Transportation. Calculation assumes fuel emissions factor for combination trucks are the same as the rest of the vehicle parc and are therefore conservative. Combination trucks use diesel fuel which, according to the Combination Trucks % of U.S. Fleet and U.S. Vehicle Emissions U.S. EPA, U.S. Department of Transportation U.S. EPA, has a higher GHG content versus gasoline used for light duty cars and trucks. OEM data sourced from respective websites and latest available ESG reports. We have recently reviewed our water intensity data and redrew boundaries based on industry convention. Tesla’s 2020 figure includes all our major manufacturing facilities dedicated to vehicle production, including an estimate for Gigafactory Nevada (actuals for 2020 for Gigafactory Nevada in later reports may vary upon confirmation of Water Consumption per Vehicle Tesla, OEM Sustainability Reports actual figures). It excludes Gigafactory New York, which produces solar and energy products. Figures based on actual electricity consumption from utility bills for 2018, 2019 and 2020. 2020 figure also includes measured consumption for on-site fuel use including propane, diesel and gasoline. Figures for 2012-2017 for electricity, and 2012-2019 for on-site fuel use, are estimated based on actuals scaled for vehicle and battery production for each respective year and facility. Fossil fuel versus clean energy consumed at each facility for each year estimated based on state-level grid mix data from DOE for facilities in the U.S. and from country-level energy supply data from IEA for Gigafactory Shanghai. We re-drew boundaries for this year’s analysis based on industry convention. Previous disclosure included energy consumed to produce cells at Gigafactory Nevada and solar panels at Gigafactory New York. These are included in Cumulative Energy Produced by Tesla Solar Panels vs. Consumed by Tesla Factories Tesla our suppliers’ energy consumption footprints and were therefore removed from calculation for this report. Figures reflective of model year 2020 estimates from various sources. Depreciation based on model year 2021 Total Cost of Ownership Tesla, Edmonds, OEM websites, CarEdge MSRP. Model 3 SR+ figures based on data from the Tesla fleet. Figures based on annual mileage for select non-Tesla EV models in the U.K. for 2017-2019. Non-Tesla EV models include BMW i3, Kia Soul EV, Mercedes-Benz B250e, Nissan Leaf 30kWh, and Renault Zoe Q210. Real world data from the Tesla fleet was used to calculate the average annual mileage for all Tesla models. RAC Foundation, ev-database.org, EPA range sourced from fueleconomy.gov. Where EPA range did not exist WLTP was used to determine a EV Range and Utilization Over First Three Years of Ownership fueleconomy.gov theoretical EPA range based on average EPA to WLTP ranges for other EVs. RMI Classification: A smelter or refiner is considered “Conformant” when they have passed a third-party audit to industry accepted standards covering their internal processes and policies on due diligence to identify and mitigate the risk of human rights abuses in their supply chain; “Active” means a smelter or refiner is pursuing certification through one of the approved auditing processes; “Not Listed” means a smelter or refiner is not yet listed on the RMI's Cobalt Reporting Template and may not yet have been engaged by the RMI to participate in the RMAP or equivalent program. Tesla 2020 Supply Chain List of Miners & Refiners for Purchased Cobalt Materials Responsible Minerals Initiative Table reflects latest data available to Tesla as of the publishing of this report. 92
