Amazon data center plant in Texas could become America’s biggest polluter

illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on The Independent or enjoy below:

🗞️ Driving the news: An Amazon data center campus in Texas could become the largest single source of carbon emissions in the US, if its planned on-site natural gas plant operates at its permitted maximum
• The plant in Pecos County is permitted to emit up to 33 million tonnes of CO₂ annually, more than twice the roughly 16 million tonnes emitted by the current largest single polluter, Alabama’s James H. Miller Jr. coal plant

🔭 The context: Amazon is building the gas plant to provide dedicated power for a massive AI-focused data center campus, reportedly its first major off-grid power investment
• The move reflects a growing trend among hyperscalers
• Microsoft, Google and Meta are also turning to fossil-fuel generation as they race to secure enough electricity for rapidly expanding AI infrastructure
• Amazon says the facility is designed to eventually transition to grid-connected power; it is exploring solar and battery storage on site
• The company also maintains its commitment to net zero emissions by 2040, despite its emissions increasing in 2025

🌍 Why it matters for the planet: The Amazon project highlights a growing contradiction: technology companies are accelerating investment in AI while simultaneously increasing demand for new gas-fired power capacity
• For companies with ambitious climate targets, the source of electricity powering their AI expansion could become a major credibility test

⏭️ What’s next: Texas has paused new data center projects while regulators assess their impact on the electricity system
• The outcome could determine how quickly the state allows additional AI infrastructure to connect to the grid and who ultimately bears the costs of the required power capacity

📈 One stat: 33 million tonnes of CO₂ per year is the maximum emissions permitted for Amazon's planned gas plant

💬 One quote: “Though our emissions increased in 2025, we remain steadfast in our commitment to sustainability.” - Amazon
