Tim Cook's environmental legacy at Apple faces AI energy demands as he steps down
Apple under Cook achieved rare emissions reductions among tech giants, but the company's AI expansion and its reliance on supplier renewables now threaten to reverse those gains.
What happened
Tim Cook stepped down as Apple CEO after setting and partially meeting aggressive climate targets. Apple reduced its carbon emissions by 60 percent toward a 75 percent reduction goal by 2030 (baseline 2015), and its gross emissions remained flat at 15.3 million metric tons in 2025 despite significant business growth. The company stood alone among major tech firms in setting 100 percent renewable electricity targets for suppliers and earned a B+ from Greenpeace East Asia. However, Apple faced allegations of misleading customers with carbon-neutral marketing claims on select Apple Watch models; a 2023 investigation found Apple stopped requiring suppliers to publicly disclose emissions, and a class action lawsuit over false carbon neutrality claims was dismissed by a California federal judge.
Context
Apple's environmental performance contrasts sharply with competitors: Google and Microsoft's emissions have surged due to data center and chip manufacturing demands for generative AI, while Apple has contained its footprint. The significance lies in whether Apple can sustain its commitments as AI computing intensifies. Environmental groups note the timing of Cook's departure may shield his legacy from the harder choices ahead. Apple's reliance on supplier renewable energy is constrained in Taiwan and South Korea, where much of its chip supply chain is concentrated and renewable access is limited. Cook also donated $1 million to Trump's 2025 inauguration and opposed stricter international greenhouse gas reporting guidelines, positioning Apple alongside companies resisting climate regulation even as it markets environmental leadership.
