Imagine taking two steps forward and then one step back. Are you, or are you not, still experiencing forward momentum?
That’s what sustainability accountants are asking themselves after California delayed the initial reporting deadline of its landmark sustainability reporting law by ninety days. SB 253 initially required companies with more than $1 billion in annual revenues to report their internal greenhouse gas (GHG) emissions to the California Air Resources Board (CARB) by August 10, 2026. But on June 24, 2026, 47 days before this initial deadline, the reporting requirement was delayed by three months to November 10, 2026.
Incidentally, if you’re thinking that “the law doesn’t apply to me because I’m not a billion dollar company,” think again. Beginning next year, the reporting requirement expands to the inclusion of Scope 3 GHGs throughout the corporate value chain. Scope 3 metrics encompass all external stakeholders of a company, including vendors and customers.
Thus, beginning next year, if you are an independent liquor store (anywhere in the world) that sells bottles of Gallo brand California chardonnay, your relevant carbon emissions within the value chain of E. & J. Gallo Winery will need to be reported by that supplier. Likewise, if you are a small restaurant that serves the wine to a customer, the winery will need to report your associated emissions data too.
Indeed, the initial passage of SB 253 was a significant step forward for sustainability accounting. The development of relevant capabilities in California’s largest companies, a development that occurred despite the three month delay, was a second step forward.
Why did the development of capabilities occur despite the delay? Sustainability accounting and reporting is a complex process that requires far more than 47 days for preparatory activities. No responsible company would have waited until June 24, 2026 to develop the appropriate capabilities.
By initially passing SB 253 into law so early, and then by waiting so long to announce a brief delay, CARB ensured that the largest firms in the state would develop their sustainability accounting functions. Whether or not the state, federal and judicial branches of government ultimately allow the legal requirements to take effect, CARB has essentially forced companies to invest considerable resources in their GHG measurement and reporting capabilities.
So think of the slight delay in SB 253 as a small step back after two large steps forward. It may have slowed the momentum of sustainability reporting, but it certainly hasn’t stopped it.
