SEC's New Climate Rules: How Public Companies Are Preparing

The Securities and Exchange Commission recently finalized its highly anticipated climate disclosure rules. While the final mandates are less strict than originally proposed, public companies still face a massive shift in how they report environmental risks. Here is what the new rules mean and how businesses are getting ready.

What the Final SEC Climate Rules Require

On March 6, 2024, the SEC voted 3-2 to adopt new regulations requiring public companies to disclose climate-related risks. The initial draft from 2022 was incredibly strict. After receiving thousands of comment letters, the final version was heavily diluted.

The most significant change was the removal of Scope 3 emissions. Here is a quick breakdown of how the emissions categories work:

• Scope 1: Direct emissions from owned or controlled sources, like a manufacturing plant or a fleet of delivery vans.
• Scope 2: Indirect emissions from the generation of purchased electricity, heating, or cooling.
• Scope 3: All other indirect emissions occurring in a company’s value chain. This includes the carbon footprint of third-party suppliers and the end consumers using the product.

Under the new rules, the SEC completely dropped the Scope 3 requirement. Instead, the agency now only requires Large Accelerated Filers and Accelerated Filers to report Scope 1 and Scope 2 emissions. Crucially, companies only need to report these numbers if they determine the emissions are “material” to their investors.

The 1% Rule for Severe Weather Events

Another major component of the SEC mandate is an amendment to Regulation S-X. Public companies must now include specific climate data directly in the footnotes of their audited financial statements.

If a severe weather event like a hurricane, wildfire, or flood causes a financial impact, the company must report it. The SEC set a strict threshold for this disclosure. Businesses must report capitalized costs, expenditures, and losses if they amount to 1% or more of the absolute value of their pretax income or total shareholders’ equity.

This requires a completely new level of accounting precision. Accountants cannot just write off storm damage as a general business expense. They must now track exactly how much a disrupted supply chain or a flooded warehouse cost the company in specific dollars and cents.

Legal Pauses and Compliance Timelines

The SEC originally set a phased timeline for these rules. Large Accelerated Filers were scheduled to begin reporting material climate risks and financial impacts for fiscal year 2025. They would then add Scope 1 and Scope 2 emissions data in fiscal year 2026.

However, heavy litigation quickly followed the March adoption. Energy companies, business advocacy groups, and states like Iowa and North Dakota filed lawsuits arguing the SEC overstepped its authority. In April 2024, the SEC voluntarily stayed the implementation of the rules. The 8th U.S. Circuit Court of Appeals is currently reviewing the consolidated lawsuits.

Despite this legal pause, corporate legal teams and chief financial officers are not slowing down. Building the infrastructure to track carbon emissions takes years. Most companies are moving forward with their preparation strategies as if the original timeline is still in place.

Upgrading Corporate Software Systems

You cannot manage what you cannot measure. For decades, corporate sustainability reports were handled by marketing teams using basic spreadsheets. The new SEC rules require investor-grade data. That means companies must treat carbon emissions with the exact same rigor as revenue and expenses.

To achieve this, corporations are buying specialized enterprise software. Products like Workiva, IBM Envizi, and SAP Sustainability Control Tower are becoming standard tools in corporate finance departments. These platforms automate the collection of utility bills, fuel receipts, and energy usage data.

These software tools also provide an audit trail. The SEC requires independent assurance (essentially an audit) for emissions data. Having a clear, trackable software system is non-negotiable for passing these audits.

The California and European Pressure

The SEC’s decision to drop Scope 3 emissions provided a brief moment of relief for corporate executives. That relief was short-lived. Many public companies must still track their supply chain emissions to satisfy other jurisdictions.

In October 2023, California passed two sweeping climate disclosure laws: Senate Bill 253 and Senate Bill 261. SB 253 applies to any public or private company doing business in California with over $1 billion in annual revenue. Unlike the SEC, California strictly requires Scope 3 emissions reporting starting in 2027.

Global companies must also comply with the European Union’s Corporate Sustainability Reporting Directive (CSRD). The EU mandates Scope 3 reporting for large companies operating within its borders. A massive multinational company like Apple or Walmart will have to gather this data anyway to satisfy regulators in Brussels and Sacramento. For these global giants, the diluted SEC rules do not actually save them much work.

Hiring and Internal Restructuring

Preparing for these disclosures requires serious human capital. Public companies are actively hiring for a new executive role: the ESG Controller. This position bridges the gap between the sustainability department and the traditional accounting department.

Companies are also setting up cross-functional climate committees. These groups typically include the Chief Financial Officer, the Chief Legal Counsel, and the Head of Sustainability. They meet regularly to assess which climate risks are financially material. For example, a real estate investment trust must evaluate if rising sea levels threaten their coastal properties, while an agricultural company must assess how prolonged droughts will impact future crop yields.

Frequently Asked Questions

When do the SEC climate rules go into effect? The rules are currently paused due to legal challenges in the 8th U.S. Circuit Court of Appeals as of April 2024. Originally, the SEC planned for Large Accelerated Filers to begin reporting climate risks for fiscal year 2025.

Does the SEC rule apply to private companies? No. The SEC mandates only apply to publicly traded companies registered with the agency. However, private companies may still have to report their carbon emissions under state laws like California’s SB 253 if they meet specific revenue thresholds.

Do companies have to audit their emissions data? Yes. The SEC requires Large Accelerated Filers to obtain limited assurance (a basic audit review) on their Scope 1 and Scope 2 emissions starting in fiscal year 2029, moving to reasonable assurance (a full audit) by fiscal year 2033.
