As Tim Cook steps down as Apple’s CEO today, he leaves behind an environmental record that sets him apart from many of his peers in the tech industry. While rivals struggle with rising emissions fueled by the AI boom, Cook has managed to steer Apple toward aggressive sustainability goals without sacrificing growth.
Progress Toward 2030 Commitments
Under Cook’s watch, Apple reported 15.3 million metric tons of gross carbon dioxide emissions in 2025. The company has successfully reduced its emissions by 60 percent compared to 2015 levels, moving closer to its 75 percent reduction goal set for the end of the decade. Notably, Apple’s carbon pollution flatlined over the past year even as the business grew.
Cook’s philosophy was rooted in economic pragmatism. "I want to see that it pencils out, because I want other people to copy it," he told CBS News in 2023 regarding renewable energy investments. This approach contrasts with Google and Microsoft, whose greenhouse gas emissions have ballooned due to the infrastructure demands of generative AI.
Controversies and Transparency Issues
The legacy is not without its blemishes. Apple has faced accusations of misleading customers with "carbon neutral" marketing for certain products, leading to a class-action lawsuit (later dismissed) and a retreat from such branding following EU regulatory shifts. Environmental groups like Greenpeace East Asia have also called for more transparency, noting that Apple no longer requires suppliers to publicly disclose their greenhouse gas emissions.
The AI Test and Political Maneuvering
Cook also navigated complex political waters, attending President Donald Trump’s 2025 inauguration and donating $1 million to the committee, even as the administration prioritized rolling back environmental rules to favor fossil fuels and AI data centers.
As John Ternus takes over as CEO, the rapid expansion of AI infrastructure represents the greatest threat to Cook's climate roadmap. "AI will be the defining test of Apple’s climate commitments," says Avex Li of Greenpeace East Asia. To preserve Cook’s legacy, the company must now prove that AI growth can coexist with absolute emission reductions and renewable energy investment.
