July 2025 US sustainability updates (Federal vs State-Level Momentum)

As global pressure for climate accountability grows, many U.S. states are moving forward with comprehensive carbon reporting requirements—filling the gap left by delayed or uncertain federal mandates.

A carbon footprint represents the total greenhouse gas (GHG) emissions caused directly and indirectly by an organization. These emissions are typically categorized into three scopes:

  • Scope 1: Direct emissions from owned or controlled sources (e.g. fuel combustion on-site).

  • Scope 2: Indirect emissions from purchased electricity, steam, heating, and cooling.

  • Scope 3: All other indirect emissions across the value chain, including supply chain, business travel, and product use—often the largest and most complex to track.

California Leads, Other States Follow

California has taken a bold lead with two landmark laws—SB 253 and SB 261—which require large companies doing business in the state to disclose their full emissions, including Scope 3, and assess their exposure to climate-related financial risks.

Inspired by California’s leadership, states such as New York, New Jersey, Colorado, Illinois, and Washington are advancing similar climate disclosure legislation. While each bill varies slightly in structure, the trend is clear: corporate climate transparency is becoming a compliance obligation, not a voluntary effort.

Federal Landscape: The PROVE IT Act

At the federal level, the PROVE IT Act (S.1863)—a bipartisan initiative—seeks to boost transparency in carbon emissions at the product level. The Act would empower the U.S. Department of Energy to develop and maintain reliable data on the carbon intensity of goods produced in the U.S. and abroad. This sets the foundation for future carbon border adjustments and fairer environmental trade policies, particularly in industries like steel, cement, and aluminum.

What This Means for Your Business ?

Even in the absence of a sweeping federal mandate, a growing number of states are requiring robust GHG reporting, particularly including Scope 3, which accounts for most corporate emissions. As Carlin notes, these state laws “cast a strong net” with potential national impact because few major firms operate in only one jurisdiction.
