California Streaming Hits a Green Wall

California's SB 253 forces billion-dollar streaming giants to track data center emissions by 2026 or face massive fines

7 Mar 2026

California air regulators have finalised rules that will force large digital media companies to report their greenhouse gas emissions, setting a compliance deadline of August 10, 2026. Under Senate Bill 253, companies with annual revenues exceeding $1bn that conduct business in the state must disclose Scope 1 and 2 emissions, which cover direct operations and purchased energy.

The mandate applies to any qualifying company active in California, regardless of where its headquarters are located. This brings major global streaming platforms and the energy-intensive data centers supporting them under mandatory carbon accounting for the first time. Failure to comply could result in fines of up to $500,000 per reporting year.

Data centers represent a growing share of industrial energy demand. Estimates supported by the US Department of Energy suggest these facilities account for more than 4 per cent of national electricity consumption, with emissions levels having tripled since 2018. The move to mandatory reporting marks a transition for a sector that has previously relied on voluntary environmental disclosures.

The California Air Resources Board (Carb) has allowed for some flexibility. Companies that were not tracking emissions by December 2024 may submit a "non-collection" statement for the initial 2026 cycle. However, the regulator expects full inventories and third-party verification to be standard from 2027.

The regulatory environment remains shadowed by legal challenges. The US Chamber of Commerce and several business associations have filed a lawsuit in the Ninth Circuit, arguing the law violates First Amendment rights. While no ruling has been issued as of April 2026, Carb has stated it intends to enforce the August deadline unless a court intervenes.

For the digital media industry, the shift necessitates immediate investment in sustainability data infrastructure. Beyond direct operations, companies must prepare for 2027, when reporting requirements expand to Scope 3 emissions. These are produced across the broader value chain, including content delivery networks and end-user hardware. Regardless of the pending litigation, the establishment of these rules signals an end to the era of discretionary climate reporting for the technology and media sectors.
