California Proposition 45 Debated, Potential Impact on Environmental Reviews and Data Centers

News ClipVoice of San Diego·CA·9/29/2026

Proposition 45 in California aims to reform the California Environmental Quality Act (CEQA) by setting strict time limits on environmental reviews and lawsuits, with proponents arguing it will accelerate development and opponents fearing weakened environmental protections. The potential impact on data center development, specifically whether they qualify for streamlined review, is a key point of debate.

The article discusses California's Proposition 45, a ballot measure designed to reform the California Environmental Quality Act (CEQA). Prop 45 seeks to impose a one-year limit on environmental reviews for proposed projects and requires lawsuits challenging project approvals to be filed within 30 days and resolved within a year, allowing construction to continue during litigation.

Proponents, including the California Chamber of Commerce, the Building Industry Association, and groups like Building A Better California (backed by figures like Sergey Brin and supported by Edison International), argue that CEQA is often exploited for frivolous lawsuits that stall essential projects, including affordable housing and clean energy, making development costly. They believe Prop 45 would reduce bureaucracy and accelerate building.

Conversely, opponents such as the California Democratic Party, the Sierra Club, and major labor unions like the State Building Construction Trades Council of California and the Ironworkers of the State of California, contend that Prop 45 would severely compromise CEQA's ability to protect the environment. They express concerns that government agencies lack the resources to conduct thorough reviews within the proposed timelines and that courts would struggle to expedite cases, potentially leading to unsafe projects.

A key point of contention is whether data centers would benefit from Prop 45's streamlined process, specifically under the "essential broadband internet access project" clause. While opponents warn that the measure could fast-track data center construction with less environmental scrutiny, supporters, represented by "Yes on Prop 45" spokesperson Amelia Matier, dismiss this as a "scare tactic," asserting that the proposition does not apply to data centers. The ultimate interpretation, should Prop 45 pass, would likely fall to the courts.
