Tim Cook did alright by the environment — but AI could upend his climate legacy

Tim Cook’s tenure as Apple CEO concludes today with a mixed environmental legacy. During his leadership, Apple established industry-leading climate targets and maintained relative discipline in managing its carbon footprint compared to competitors. The company achieved a 60 percent reduction in emissions toward its goal of a 75 percent decrease by the end of the decade, with carbon pollution holding steady over the past year despite significant business growth.

Apple distinguished itself through supplier standards that earned recognition from environmental groups. A 2023 assessment found Apple was the only major technology company among those evaluated that had set a 100 percent renewable electricity target for its suppliers. In 2025, the company received a B+ rating from Greenpeace East Asia for its renewable energy initiatives across supply chains. This contrasted sharply with competitors like Nvidia, whose supply chain emissions targets and commitments remained unclear.

However, the environmental record faced substantial challenges. Apple faced criticism and legal action over marketing certain products as carbon neutral, with questions raised about verification and transparency. A federal judge dismissed a class action lawsuit this year, though the company subsequently discontinued carbon neutral product advertising following European Union restrictions on such claims. Environmental groups also noted that Apple had stopped requiring suppliers to publicly disclose greenhouse gas emissions, making claims harder to verify.

Looking forward, observers questioned whether Apple could maintain Cook’s environmental commitments as it prioritizes artificial intelligence development. Competing technology companies like Google and Microsoft saw emissions surge due to AI infrastructure demands. Energy requirements for data centers and chip manufacturing posed challenges that could strain Apple’s climate goals, particularly given the concentration of chip supply chains in regions where renewable energy access remained constrained. Environmental advocates urged the company to increase direct renewable energy investment and transparency measures.
