Mercury and Air Toxics Standards (MATS) repealed:

The Trump administration scrapped Biden-era limits on toxic emissions from coal-fired power plants, including neurotoxic mercury linked to serious health issues like neurological damage and birth defects. Critics say this move prioritizes industry profits over public health.

AI energy demand is reshaping the grid:

U.S. electricity needs are climbing with AI data center build-outs, electric vehicle adoption, and increased manufacturing, putting pressure on power infrastructure. In this context, older coal plants are being kept online rather than retired.

Coal plants remain major polluters:

Coal has historically contributed roughly half of U.S. mercury emissions. Rolling back MATS could allow higher pollution levels despite long-term declines in coal’s overall use.

EPA claims economic savings:

Officials project the regulatory rollback will save about $78 million annually by 2028, arguing that outdated rules were slowing infrastructure deployment.

Environmental groups push back:

Organizations like Earthjustice argue that loosening pollution standards undermines community health and the climate goals many tech companies publicly support, especially as the tech industry depends on cleaner power supply.

Deadly attack in British Columbia:

On February 10, 2026, an 18-year-old killed nine people, including family members and students at Tumbler Ridge Secondary School, before taking her own life, the deadliest school shooting in Canada in decades.

ChatGPT account was flagged months earlier:

OpenAI’s systems detected violent and disturbing conversations with ChatGPT by the eventual shooter as far back as June 2025 and banned the account for violating use policies.

Internal debate over law enforcement referral: 

Several OpenAI employees raised concerns and suggested alerting authorities, but the company ultimately decided the content did not pose a clear, imminent threat and did not meet the threshold for reporting to police at that time.

Cooperation after the tragedy: 

Following the shooting, OpenAI shared information with the Royal Canadian Mounted Police to assist the ongoing investigation, and authorities continue to review both digital and physical evidence.

Broader tech safety concerns: 

The incident has sparked discussions about how AI companies balance user privacy with public safety, the effectiveness of automated monitoring systems, and when tech platforms should involve law enforcement.
