Companies Maintain Focus on Scope 3 Emissions Disclosure Despite Fragmented Global Regulations

Companies are continuing to prioritize disclosure and management of Scope 3 greenhouse gas emissions despite an increasingly fragmented global regulatory environment, according to new research highlighted by ESG Dive and based on findings from sustainability software and data firm Sphera.

Scope 3 emissions, which include indirect emissions across a company’s value chain, such as purchased goods and services, transportation, product use, and end-of-life treatment, often represent the largest share of a company’s total carbon footprint. For many sectors, Scope 3 can account for more than 70% of total emissions. Yet they remain the most complex to measure and report due to reliance on supplier data, estimation methodologies, and evolving accounting standards.

The survey results suggest that despite regulatory uncertainty in some markets, companies are not stepping back from Scope 3 efforts. Instead, many are strengthening data collection processes, investing in digital tools, and engaging suppliers more actively.

Regulation Diverges, Pressure Persists

In recent years, regulatory frameworks for climate disclosure have advanced unevenly. In the United States, the U.S. Securities and Exchange Commission finalized climate disclosure rules that stopped short of mandating Scope 3 reporting across the board, focusing instead on Scope 1 and Scope 2 emissions for most registrants. Legal and political challenges have further complicated implementation timelines.

By contrast, the European Union has moved ahead with broader sustainability reporting requirements under the Corporate Sustainability Reporting Directive. The directive requires many large companies to disclose material Scope 3 emissions as part of their broader environmental, social, and governance reporting. This divergence has created a patchwork of obligations for multinational firms.

However, regulatory mandates are only one part of the equation. Investors, customers, and lenders are increasingly requesting comprehensive emissions data, including value chain impacts. Many financial institutions now incorporate Scope 3 metrics into risk assessments, transition planning, and engagement strategies. This market pressure is encouraging companies to maintain or expand reporting efforts even in jurisdictions where requirements are less prescriptive.

Scope 3 as a Strategic Imperative

For companies with net zero commitments, excluding Scope 3 emissions would undermine the credibility of transition plans. Most science-based targets aligned with the Paris Agreement require inclusion of value chain emissions where they represent a significant portion of the total footprint.

The Science-Based Targets initiative requires companies to set Scope 3 reduction targets if those emissions account for more than 40% of total emissions. As a result, businesses seeking validation of their climate targets must invest in Scope 3 data and reduction strategies.

This shift has elevated Scope 3 from a compliance exercise to a strategic priority. Companies are increasingly mapping their supply chains, identifying emissions hotspots, and collaborating with suppliers to improve data accuracy and reduce carbon intensity. In sectors such as manufacturing, retail, food, and technology, supplier engagement programs are expanding rapidly.

Digitalization plays a critical role. Companies are adopting lifecycle assessment tools, supplier data platforms, and emissions factor databases to standardize reporting and reduce reliance on generic estimates. Artificial intelligence and automation are also being deployed to analyze large datasets and identify decarbonization opportunities.

Operational and Financial Implications

Managing Scope 3 emissions has direct operational implications. Procurement teams are being asked to incorporate carbon performance into supplier selection criteria. Contractual clauses increasingly require emissions disclosures or decarbonization commitments. Some companies are linking executive compensation to progress on value chain emissions reduction.

From a financial perspective, understanding Scope 3 emissions can reveal exposure to transition risks. For example, companies heavily dependent on carbon-intensive materials may face cost increases as carbon pricing mechanisms expand globally. Transparent reporting can also improve access to sustainable finance instruments, such as green bonds or sustainability-linked loans.

At the same time, challenges remain significant. Data gaps persist, particularly among small and medium-sized suppliers with limited reporting capacity. Methodological inconsistencies across industries can complicate benchmarking. Companies operating in multiple jurisdictions must navigate differing definitions of materiality and assurance requirements.

Nevertheless, the overall trend appears clear. Rather than retreating in response to regulatory uncertainty, many organizations view Scope 3 transparency as essential to maintaining investor confidence and competitive positioning.

Toward Greater Standardization

Global standard-setting bodies are working to improve alignment. The International Sustainability Standards Board has issued climate disclosure standards that incorporate value chain emissions where material. Over time, convergence between regional frameworks may reduce fragmentation and improve comparability.

In parallel, industry collaborations are emerging to harmonize data requests and reduce reporting burdens for suppliers. Shared platforms and sector-specific guidance aim to streamline emissions accounting while enhancing accuracy.

For stakeholders in the net-zero transition, the continued prioritization of Scope 3 reporting signals a maturation of corporate climate governance. It reflects a broader understanding that climate risk and opportunity extend beyond direct operations and into the full lifecycle of products and services.

As regulatory landscapes continue to evolve, companies that have already invested in robust Scope 3 data systems may be better positioned to adapt. More importantly, they will have a clearer view of where emissions reductions are most impactful, enabling more credible and actionable decarbonization strategies.

In a fragmented policy environment, market forces and long-term climate commitments appear to be sustaining momentum. Scope 3 emissions disclosure, once seen as an aspirational goal, is increasingly becoming a baseline expectation for companies seeking to demonstrate climate leadership and resilience.
