Why Does Climate Change Law Matter for Corporate Compliance?

Disclosure obligations depend on whether you are a public company, large private entity, financial institution, or supply chain supplier. Public companies and SEC-filers face proposed rules requiring disclosure of Scope 1 and Scope 2 greenhouse gas emissions, climate-related financial risks, and board-level governance of climate issues. Large private companies and financial institutions often must comply with state-level climate disclosure mandates or industry-specific frameworks. Suppliers to regulated entities, particularly in California and the Northeast, may face contractual or statutory requirements to report emissions data or certify climate risk management practices. The first procedural step is conducting an internal audit to identify which regulatory regimes apply to your operations, then mapping your current disclosures against each standard to identify gaps.

New York State has enacted climate-focused statutes affecting corporations operating in or sourcing from the state, including the Climate Leadership and Community Protection Act and building performance standards that mandate emissions reductions in large commercial and residential properties. New York courts have shown willingness to recognize climate-related claims in tort and contract disputes, so corporations cannot treat climate risk as purely regulatory. It carries litigation exposure. Companies with significant New York real estate assets or operations must ensure their climate governance documentation is current and defensible, as delays in updating emissions baselines or risk assessments can create evidentiary gaps if disputes arise.

Regulators deploy several enforcement tools: administrative orders requiring emissions reductions or remediation, civil penalties for disclosure violations or failure to meet reporting deadlines, and injunctive relief mandating specific climate adaptation or mitigation measures. The SEC and state securities regulators focus on disclosure accuracy and completeness. Environmental agencies typically target emissions reductions and facility-level compliance. State attorneys general increasingly use climate-related consumer protection statutes to challenge corporate greenwashing or misleading environmental claims. Corporations that maintain contemporaneous records of their climate risk assessment process, board-level deliberations, and compliance efforts create a stronger defense posture if challenged, as they can demonstrate the reasonableness of their disclosures and mitigation choices.

Documentation discipline is critical. Corporations should maintain records of how climate risks were identified, evaluated, and escalated within the organization; board materials discussing climate strategy and financial materiality; third-party climate risk assessments or scenario analyses; and communications with external advisors regarding risk quantification. This documentation demonstrates that the company took climate risk seriously and acted on material information. It provides a contemporaneous record of decision-making that courts and regulators will review and supports any future disclosure or regulatory response by showing the company's analytical process. When documentation is sparse or created only after a complaint arises, regulators and plaintiffs often infer that the company downplayed or ignored known risks, which undermines any subsequent compliance narrative.

Scope 1 emissions are direct greenhouse gas emissions from sources a company owns or controls, such as company vehicles or manufacturing facilities.

Scope 2 emissions result from purchased electricity or energy used by the company.

Scope 3 emissions are indirect emissions from a company's value chain, including supplier operations and product use by customers.

Regulators and investors increasingly demand that corporations disclose all three scopes, but Scope 3 is the most challenging because it requires collaboration with suppliers and customers and involves estimation rather than direct measurement. Corporations often underestimate Scope 3 exposure. If your industry or customer base is carbon-intensive, your Scope 3 footprint may dwarf direct emissions, and regulators may challenge your disclosure if you omit or minimize this category. Our environmental and climate change team assists corporations in mapping supply chain emissions and establishing governance frameworks that satisfy disclosure standards while maintaining operational flexibility.

Yes, corporations increasingly face liability for supplier climate practices through contractual indemnification clauses that shift liability to suppliers, regulatory mandates requiring buyer accountability for supplier emissions, and tort claims alleging that the buyer knew or should have known of supplier practices that contributed to climate harm. Corporations that fail to conduct due diligence on supplier climate practices or that ignore red flags regarding supplier emissions expose themselves to contractual breach claims, regulatory enforcement, and reputational damage. Establishing supplier climate performance standards, conducting periodic audits, and documenting your oversight efforts reduces this exposure and demonstrates to regulators and courts that you exercised reasonable care in managing supply chain risk.

Prompt identification and correction of disclosure gaps or errors significantly reduces regulatory and litigation exposure. If your company discovers that prior disclosures omitted material climate risks, were based on inaccurate emissions data, or failed to reflect board-level climate governance, you should immediately notify your legal and compliance teams, assess the materiality of the error, and determine whether an amended disclosure, press release, or regulatory filing is required. Voluntary correction, particularly before regulators or plaintiffs identify the gap, demonstrates good faith and often results in lighter enforcement treatment. Conversely, if a regulator or litigant uncovers a gap that your company knew about but did not disclose, the company faces allegations of intentional concealment, which carries higher penalties and reputational damage.

When a corporation receives a regulatory inquiry, shareholder demand letter, or climate-related lawsuit, the first procedural step is to preserve all documents related to climate risk, emissions data, board discussions, and prior disclosures. Many corporations fail at this stage by continuing to delete routine emails or allowing document retention policies to destroy relevant records after the inquiry arrives. Once a litigation hold is in place, the corporation should conduct an internal investigation to understand the scope of the claim, identify gaps in documentation or disclosures, and assess the strength of any defenses. Engaging outside counsel early, before providing substantive responses to regulators or litigants, protects attorney-client privilege and work product doctrine, which shield your investigation from discovery. The corporation should also consider whether the claim implicates insurance coverage and notify insurers promptly to preserve coverage rights.
