Tim Cook has left Apple with a commendable environmental record, but the rise of AI may test those achievements. Under his leadership, Apple set ambitious goals and led in sustainable practices, but its carbon footprint remains a concern. Now, as generative AI demands more energy, Apple's commitment to clean tech faces an uncertain future.

Despite reductions in emissions, Apple has faced accusations of misleading customers. Its renewable energy targets and carbon-neutral claims may falter as the tech industry grapples with AI's environmental impact. The company's supply chain, while improving, still faces scrutiny over forced labor and conflict minerals.

Apple's opposition to stricter greenhouse gas reporting guidelines and its financial support for fossil fuels during Trump's administration raise questions about its long-term commitment to sustainability. As AI scales, the pressure on tech giants to balance growth with environmental responsibility will only increase.

For Cook, leaving as Apple navigates these challenges may be a strategic move. However, the coming years could define whether his legacy is remembered as a beacon of sustainability or a victim of technological change.
