Introduction Climate Change Resources Smarter Chemistry Engagement and Advocacy Appendix 2023 Environmental Progress Report 107 o The breakdown of the carbon footprint into life cycle phases manufacturing, transportation, product use and recycling o Detailed product specific split into life cycle phases o The contribution of individual products and product families to the overall carbon footprint The data and information supporting the GHG assertion were projected (use phase and recycling) and historical (i.e. fiscal year 2022 data regarding sales figures, manufacturing, transportation, use patterns where available). This review comprises a check of selected data, which are most influential to the overall carbon footprint. The overall plausibility check addressed the following questions:  Are product LCAs referenced and updated with more recent data correctly?  Are results for products, for which no full LCA review was undertaken, plausible? This review was done remotely. 3 Findings In FY2022 and beginning of FY2023 11 recent product LCA studies have been reviewed successfully against ISO 14040/44. These LCAs cover product segments iPhone, iPad, MacBook Air, and MacBookPro. These recently reviewed LCA studies cover products which represent in total 35.6% of the total scope 3 carbon footprint. Representatives of other product segments (iMac, Apple Watch, iPod, Mac Pro, HomePod, AirPort Express / AirPort Extreme, Apple TV, Airpods and Beats products) underwent no or only minor design changes compared to those which went through a full LCA review in former years. All reviewed LCA studies up to now cover in total 68.4% of the total scope 3 carbon footprint. All questions raised in the course of the review were answered by Apple and related evidence was provided where needed. 4 Conclusions Apple’s assessment approach is excellent in terms of granularity of the used calculation data. A significant share of components is modelled with accurate primary data from Apple’s suppliers. Comprehensive Carbon Footprint Letter of Assurance 3 Client: Apple Inc.
