Introduction: The Gap Between Concept and Execution
In recent years, Scope 1 and Scope 2 emissions have become relatively well understood among Indian companies. Organisations have begun tracking fuel consumption, electricity usage, and associated emissions with increasing clarity. However, when it comes to Scope 3 emissions, the conversation often shifts from confidence to uncertainty.
Scope 3 emissions represent indirect emissions that occur across the value chain, both upstream and downstream. While the concept is widely acknowledged, the practical implementation remains one of the most complex and misunderstood aspects of ESG reporting.
Many organisations either do not report Scope 3 emissions or rely on broad estimates that do not accurately reflect their actual impact. The challenge is not due to lack of intent, but due to the inherent complexity of value chain data, the absence of structured systems, and the difficulty of engaging suppliers and partners.
This has resulted in a situation where Scope 3 is frequently disclosed in a limited or inconsistent manner, even though it often constitutes the majority of a company’s total emissions.
Understanding What Scope 3 Actually Covers
Scope 3 emissions extend beyond the direct control of the organisation. They include emissions associated with purchased goods and services, transportation, waste generated in operations, business travel, employee commuting, and the use and disposal of products.
Unlike Scope 1 and Scope 2, which are linked to internal operations, Scope 3 requires companies to look outward into their value chain. This includes suppliers, logistics providers, distributors, and even customers in certain cases.
The breadth of Scope 3 categories makes it inherently complex. Each category has its own data requirements, calculation methodologies, and dependencies on external stakeholders. This complexity is one of the primary reasons why companies struggle to move beyond high level estimates.
Why Scope 3 Becomes Difficult in Practice
The primary challenge with Scope 3 lies in the fact that the data required is not directly controlled by the reporting company. Instead, it depends on the availability, accuracy, and willingness of external stakeholders to provide information.
In the Indian context, a large portion of the value chain consists of small and medium enterprises. These entities may not have formal systems for tracking energy usage, emissions, or environmental impact. As a result, collecting primary data becomes difficult.
Even when data is available, it may not be in a format that aligns with emission calculation requirements. Suppliers may provide basic consumption figures without standardisation, making it challenging to convert this information into reliable emission estimates.
In such cases, companies often resort to secondary data or industry averages. While this approach is acceptable as a starting point, it does not provide the level of accuracy required for credible ESG reporting.
The Misinterpretation of Scope 3 Boundaries
Another issue that contributes to misreporting is the lack of clarity around organisational boundaries. Companies often struggle to determine which parts of their value chain should be included in Scope 3 calculations.
For example, there may be uncertainty around whether to include emissions from certain categories of suppliers, how to account for outsourced activities, or how to treat joint ventures and partnerships.
Without clear boundary definition, companies may either underreport or overreport Scope 3 emissions. This affects not only the accuracy of disclosures but also the ability to track progress over time.
The Reliance on Estimates and Its Limitations
In the absence of primary data, many organisations rely on emission factors and industry benchmarks to estimate Scope 3 emissions. While this is a recognised approach under global standards, it has limitations.
Estimates based on generic data do not capture the specific characteristics of a company’s value chain. They may not reflect differences in supplier practices, regional variations, or operational efficiencies.
Over time, continued reliance on estimates can create a disconnect between reported emissions and actual impact. This becomes particularly relevant when companies begin to set reduction targets or engage with investors and stakeholders.
The Challenge of Supplier Engagement
Effective Scope 3 reporting requires active engagement with suppliers. However, this is often one of the most challenging aspects for Indian companies.
Suppliers may not prioritise ESG reporting, especially if they are not directly regulated or do not see immediate business benefits. There may also be concerns around sharing data, lack of technical knowledge, or limited resources to support reporting requirements.
For large organisations with extensive supplier networks, engaging each supplier individually becomes resource intensive. This creates a barrier to collecting consistent and reliable data across the value chain.
Why Scope 3 Is Becoming Increasingly Important
Despite these challenges, the importance of Scope 3 emissions is increasing. For many sectors, Scope 3 represents a significant portion of total emissions, often exceeding Scope 1 and Scope 2 combined.
Investors, customers, and global partners are increasingly looking at value chain emissions to assess the overall sustainability performance of companies. In addition, regulatory frameworks are gradually expanding to include value chain considerations.
This means that companies can no longer limit their focus to internal operations. They need to develop a broader understanding of their environmental impact across the entire value chain.
Moving Towards Practical Implementation
Addressing Scope 3 challenges requires a phased and structured approach. Companies need to start by identifying the most relevant categories based on their business model and sector.
Instead of attempting to cover all categories at once, it is more effective to prioritise areas with the highest impact and gradually expand coverage. This allows organisations to build internal capability and refine methodologies over time.
Supplier engagement also needs to be approached strategically. Providing guidance, templates, and training can help suppliers understand reporting requirements and improve data quality.
At the same time, companies need to develop internal systems that can integrate supplier data, apply consistent methodologies, and maintain documentation for reporting and assurance purposes.
Conclusion: From Estimation to Accountability
Scope 3 represents one of the most challenging aspects of ESG reporting, but it is also one of the most critical for understanding a company’s true environmental impact.
The current gap between concept and execution reflects the early stage of maturity in value chain data management. However, as expectations increase, companies will need to move from estimation-based reporting to more accurate and accountable disclosures.
This transition will require investment in systems, stronger supplier engagement, and a shift in how organisations view their responsibility within the broader value chain.
