California’s impending climate laws will mark a tectonic shift in environmental responsibility and reporting standards for American consumer goods companies, far exceeding any current federal mandates.
The Climate Corporate Data Accountability Act (SB 253) and the Climate-Related Financial Risk Act (SB 261) will require that all businesses operating in the Golden State disclose greenhouse gas (GHG) emissions and analyze financial risks stemming from climate-related performance issues—and with reporting beginning in 2026, companies are scrambling to shape their strategies for compliance.

This week, Cascale and sustainability data insights platform Worldly published a resource for enterprises looking to stay abreast of the state’s revolutionary climate laws, known collectively as the California Climate Accountability Package.
The groups’ analysis highlights the intersecting objectives of governmental regulation and third-party verification tools and aims to provide a roadmap for compliance for consumer goods companies.
According to Cascale, the laws, which will first impact large companies, will bring to the surface specific challenges for apparel, footwear and textiles companies that have complex supply chains.
The Scope 3 disclosure requirements within SB 253 may become hurdles for brands that haven’t yet done the work to collect emissions metrics from all their suppliers. Legal constraints, like data protection laws in certain sourcing locales, could also impede the transmission of necessary information across borders.
Now that these firms will have to track and report on their impacts throughout the value chain, existing processes and methodologies for measuring impacts may not be enough.
“The California climate laws are part of the growing global pattern of holding businesses accountable for their environmental impacts,” Wordly vice president of sustainability J.R. Siegel said. “To understand their impact reduction opportunities and report Scope 3 emissions more accurately, businesses need primary data from across their entire supply chains.”
California often leads the way in corporate climate and sustainability legislation, implementing standards that set a precedent for other states, as well as federal policy, underscoring the importance of developing a cohesive strategy for compliance.
Earlier this year, the world’s fifth largest economy passed the Voluntary Carbon Market Disclosures Act (AB 1305), an anti-greenwashing measure that will require all firms doing business in California and marketing net-zero emissions or carbon-neutral status to back up their claims.
Meanwhile, the California Responsible Textile Recovery Act (SB 707), which was signed into law by Governor Gavin Newsom in September, will create the country’s first extended producer responsibility (EPR) program for textile and apparel waste.
“These laws are a critical step forward for addressing climate impacts, not just for the U.S. but globally,” Cascale senior director of policy and public affairs Elisabeth von Reitzenstein said.
“California’s Climate Accountability Package arrives at a pivotal time, as businesses worldwide face growing pressure to demonstrate their climate commitments,” she added. “By requiring companies to disclose GHG emissions across their entire supply chain, California is setting a new benchmark for transparency and accountability.”
Von Reitzenstein acknowledged that while global standard harmonization is the “ultimate goal,” regional and national laws will help ensure progress.
“Strengthening enforcement at the national level, while drawing on established global standards and industry initiatives, will therefore be key to driving meaningful progress on combating climate change,” she said.
