California lawmakers approve the nation’s most sweeping emissions disclosure rules for big business

California lawmakers have approved legislation requiring major companies to disclose a sweeping range of greenhouse gas emissions

Major corporations from oil and gas companies to retail giants would have to disclose their direct greenhouse gas emissions as well as those that come from activities like employee business travel under legislation passed Monday by California lawmakers, the most sweeping mandate of its kind in the nation.

The legislation would require thousands of public and private businesses that operate in California and make more than $1 billion annually report their direct and indirect emissions. The goal is to increase transparency and nudge companies to evaluate how they can cut their emissions.

“We are out of time on addressing the climate crisis,” Democratic Assemblymember Chris Ward said. “This will absolutely help us take a leap forward to be able to hold ourselves accountable.”

The legislation was one of the highest profile climate bills in California this year, racking support from major companies that include Patagonia and Apple, as well as Christiana Figueres, former executive secretary of the United Nations convention behind the 2015 Paris climate agreement.

The bill received 41 votes in the Assembly, just enough to pass and send it back to the Senate for a final vote before it would reach Democratic Gov. Gavin Newsom. Lawmakers backing the bill say a large number of companies in the state already disclose some of their own emissions. But the bill is a controversial proposal that many other businesses and groups in the state oppose and say will be too burdensome.

Newsom declined to share his position on the bill when asked last month. His administration’s Department of Finance opposed it in July, saying it would likely cost the state money that isn’t included in the latest budget. Newsom has advanced California’s role as a trendsetter on climate policies by transitioning the state away from gas-powered vehicles and expanding wind and solar power. By 2030, the state has set out to lower its greenhouse gas emissions by 40% below what they were in 1990.

State Sen. Scott Wiener, a San Francisco Democrat who introduced the disclosure bill, said in a statement that it would allow California to “once again lead the nation with this ambitious step to tackle the climate crisis and ensure corporate transparency.”

California has a lot of big companies that export everything from electronics to transportation equipment to food, and most every major company in the country does business in the state, which is home to about one in nine Americans. Newsom often boasts about the state’s status as one of the world’s largest economies.

The policy would require more than 5,300 companies to report their emissions, according to Ceres, a nonprofit policy group supporting the bill.

About 17 states, including California, have inventories requiring large polluters to disclose how much they emit, according to the National Conference of State Legislatures. California’s climate disclosure bill would be different because of all the indirect emissions companies would have to report. Additionally, companies would have to report based on how much money they make, not how much they emit.

The U.S. Securities and Exchange Commission proposed rules that would make public companies disclose their emissions, up and down the supply chain. But the California bill would go beyond that, by mandating that both public and private companies report their direct and indirect emissions.

The legislation would make large companies disclose their own greenhouse gas emissions and emissions released indirectly from sources including employee business travel, the transport of products and waste disposal. For example, a major retailer would have to report emissions from powering its own buildings, as well as those that come from delivering products from warehouses to stores.

Opponents of the bill say it is not feasible to accurately account for all of the mandated emissions from sources beyond what companies are directly responsible for.

“We’re dealing with information that’s either unreliable or unattainable,” said Brady Van Engelen, a policy advocate at the California Chamber of Commerce.

The chamber, which advocates for businesses across the state, is leading a coalition that includes the Western States Petroleum Association, the California Hospital Association and agricultural groups, in opposing the bill. They argue many companies don’t have enough resources or expertise to accurately report emissions and say the legislation could lead to higher prices for people buying their products.

Hundreds of companies in California already have to disclose their direct emissions through the state’s cap and trade program, said Danny Cullenward, a climate economist and fellow at the University of Pennsylvania’s Kleinman Center for Energy Policy. The decade-old program, which allows large emitters to buy allowances from the state to pollute and trade them with other companies, is one of the largest in the world.

Cullenward said the disclosure bill could lead to similar proposals in other states as federal regulators, faced with possible lawsuits in the future over disclosure mandates, “are going to be under pressure to not overreach.”

Supporters of the disclosure bill acknowledge it’s not a “perfect” solution that would guarantee flawless emissions reports. But they say it’s a starting point. California Environmental Voters, which supports the bill, says the legislation would put pressure on companies to move faster in lowering their emissions.

“Our state can’t just take 2023 off in terms of climate action,” said Mary Creasman, the group’s chief executive officer.

The California Air Resources Board would have to approve regulations by 2025 to implement the bill’s requirements. Companies would have to begin publicly disclosing their direct emissions annually in 2026 and start annually reporting their indirect emissions starting in 2027. Companies would have to hire independent auditors to verify their reported emissions releases.

A similar proposal introduced last year passed the state Senate but failed in the Assembly. Wiener, the San Francisco Democrat who introduced the legislation both years, has said proponents of the bill built a stronger coalition this year to have a better outcome.

A key committee in the state Assembly blocked legislation earlier this year that would have sped up the state’s timeline for reducing greenhouse gas emissions. Lawmakers are also weighing a bill that would require companies making more than $500 million to disclose how climate change could hurt them financially.
