Impact of SEC Climate Rules on Supply Chains
The SEC's climate disclosure rules are reshaping manufacturing supply chains, demanding better emissions tracking and supplier collaboration.
The SEC's new climate disclosure rules, starting in 2024, are reshaping how companies report greenhouse gas emissions and climate risks. These regulations require detailed reporting on direct (Scope 1) and indirect (Scope 2) emissions, as well as climate risk management strategies. For manufacturers, the focus extends beyond their operations to their supply chains, where most emissions originate. Here's what you need to know:
- Scope 1 & 2 Reporting: Companies must track emissions directly from operations and indirectly from energy use.
- Supply Chain Emissions: Upstream and downstream suppliers significantly impact overall emissions, making supply chain transparency critical.
- Compliance Costs: Large companies face annual costs of $2–$5 million initially, with ongoing expenses for audits and data systems.
- Global Challenges: International suppliers and varying regulations complicate data collection and reporting.
- Technology Solutions: Tools like carbon management platforms and IoT monitoring help streamline emissions tracking.
The rules prompt manufacturers to engage suppliers, improve data systems, and manage higher compliance costs. While challenging, they also push industries toward better emissions tracking and accountability.
Understanding the Regulatory Landscape
SEC climate regulations differ based on a company's size and filing status, with varying deadlines and requirements. For manufacturers, it's essential to determine their specific filing category to ensure compliance. These rules are prompting manufacturers to reassess how they manage and track data across their supply chains.
Phased Implementation Timeline
The SEC has introduced a phased approach for implementing its rules. Larger companies face earlier deadlines and stricter verification requirements, while smaller companies benefit from extended timelines and less rigorous verification. This staggered schedule means major manufacturers must gather emissions data from their suppliers well before those suppliers are required to report.
Scope 1 and Scope 2 Emissions Reporting
Understanding emissions reporting - specifically Scope 1 and Scope 2 - is a key challenge for supply chains. Scope 1 emissions, which are direct, are generally simpler to verify. However, collecting data on Scope 2 emissions, which are indirect and influenced by factors like energy production methods and regional energy mixes, can be far more complex when dealing with multiple suppliers.
Impact on Manufacturing Supply Chains
The SEC climate rules are reshaping manufacturing supply chains in ways that go far beyond regulatory compliance. From overhauling data collection processes to redefining supplier relationships and escalating costs, these regulations push manufacturers to scrutinize the environmental practices of their entire network of suppliers. This shift brings to light challenges in managing data, supplier collaboration, and expenses.
Data Collection Challenges
One of the biggest hurdles manufacturers face is gathering precise emissions data from their suppliers. This task becomes even more complicated when dealing with international suppliers, as they often operate under varying reporting standards. To make matters worse, many suppliers lack the infrastructure to track and report emissions accurately.
The issue is particularly pressing when you consider that Scope 3 emissions - those generated throughout the supply chain - can account for a staggering 70–90% of a company’s total carbon footprint. While federal SEC rules have somewhat eased Scope 3 reporting requirements, stricter state laws in California and New York, along with international frameworks like the EU’s Corporate Sustainability Reporting Directive (CSRD), demand more thorough tracking. For manufacturers with global operations, navigating this patchwork of regulations is a logistical headache, further complicating the already difficult task of collecting reliable data.
Supplier Engagement and Collaboration
The new regulations also force manufacturers to rethink how they work with their suppliers. Once data gaps are identified, companies must actively engage with suppliers to close them. Procurement teams are now tasked with evaluating suppliers not just on cost, quality, and delivery, but also on their ability to report environmental data and adopt sustainable practices. In many cases, manufacturers are even training their suppliers to improve their data collection systems.
But collaboration doesn’t stop at data. Manufacturers and their supply chain partners are working together to create standardized reporting formats, set benchmarks for data quality, and establish verification processes. These efforts often highlight gaps in supplier capabilities, leading to tough decisions about whether to invest in developing those suppliers or to seek out partners who are already compliant. The pressure is further amplified as private suppliers increasingly need to provide climate-related data to their public company clients, creating a domino effect where regulatory demands influence supplier selection and retention across the board.
Higher Compliance Costs
These regulatory changes come with a hefty price tag. For large companies, initial compliance costs are estimated between $2–$5 million annually, with ongoing expenses for third-party audits and software integration adding to the financial strain. According to the SEC, annual compliance costs could range anywhere from $197,000 to over $739,000, depending on the reporting requirements.
Managing supply chain data adds another layer of expense. Many manufacturers have to invest heavily in new systems, hire additional personnel, and dedicate resources to supplier engagement. Small and mid-sized companies often feel the pinch the most, as they’re typically starting from scratch without the benefit of voluntary disclosure practices or in-house sustainability expertise. On top of this, the U.S. Chamber of Commerce estimates that fragmented state regulations could drive up compliance costs by 30–50% for multinational firms operating in different jurisdictions.
Indirect costs also pile up. Adjustments to supplier contracts, the introduction of new procurement criteria, and even restructuring supply chains to work with environmentally compliant partners can all impact a company’s bottom line. These changes ripple through entire manufacturing sectors, influencing pricing, competitiveness, and market dynamics in ways that are hard to ignore.
Insights from Industry Studies
Recent research sheds light on the challenges manufacturers face in meeting new climate disclosure requirements, while also showcasing emerging strategies to bridge these gaps.
Preparedness of Manufacturers
A study of California's leading suppliers revealed that only 25% currently disclose Scope 1 and 2 emissions, and an even smaller 18% report Scope 3 emissions. This is significant because supply chain emissions are, on average, 11.4 times greater than operational emissions, accounting for over 80% of a global company's carbon footprint. The findings also show that just 10% of suppliers have obtained third-party assurance for their greenhouse gas emissions data, 11% have set science-based emissions reduction targets, and 17% have conducted climate-related risk assessments in line with the Task Force on Climate-related Financial Disclosures framework.
These low compliance levels are further complicated by California's SB 253, which mandates emissions disclosures starting in 2026. The combination of these challenges has led many manufacturers to explore technology-driven solutions to meet these upcoming requirements.
Technology Adoption and New Solutions
To address compliance gaps, manufacturers are increasingly adopting digital tools designed to simplify emissions tracking and reporting. Carbon management platforms are becoming essential, offering centralized systems for data validation, scenario analysis, goal tracking, and reporting. Real-time IoT monitoring is also gaining popularity, providing continuous tracking of emissions and delivering accurate, verifiable data for audits. By integrating these technologies into their enterprise risk management systems, manufacturers can not only improve data accuracy but also uncover operational efficiencies and cost-saving opportunities.
Best Practices for Supply Chain Sustainability
Forward-thinking manufacturers are taking a strategic approach to sustainability. Before investing in new systems, they assess their existing climate data to ensure upgrades are both targeted and effective. Contract manufacturers, in particular, are evaluating potential clients' reporting needs during procurement to better understand disclosure requirements. Additionally, embedding climate considerations into enterprise risk management systems allows businesses to address environmental risks alongside traditional ones, leading to more informed and well-rounded decision-making. These steps are helping manufacturers build stronger, more resilient supply chains equipped to handle climate-related challenges.

Creating a Supplier Reporting Framework
Streamlining supplier reporting is another essential step. A structured approach ensures that suppliers with varying capabilities and emissions impacts are engaged effectively. Segment suppliers into four groups based on their emissions and ability to act:
- Innovation suppliers: Provide financial incentives like green premiums or long-term contracts to maximize their emissions reduction potential.
- Intervention suppliers: Focus on building their capacity through non-financial rewards and light penalties to encourage progress.
- Compliance suppliers: Require mandatory reporting and apply non-financial penalties, offering minimal support.
- De-prioritization suppliers: Maintain basic due diligence and performance standards without additional engagement.
Use targeted indicators to track supplier progress. Combine general metrics - like data quality, carbon accounting, and governance - with sector-specific measures such as Product Carbon Footprint (PCF) capacity, recycled content tracking, and emissions reduction initiatives.
To drive emissions reductions, implement abatement levers tailored to each supplier group. Align financial and non-financial rewards or penalties with their performance to ensure resources are used efficiently.
Lastly, establish clear communication protocols and data-sharing standards. User-friendly platforms can simplify emissions calculations for smaller suppliers, reducing their burden and improving data accuracy across the supply chain. This approach creates a more cohesive and effective reporting framework for all stakeholders.
