When it comes to environmental pollution, emissions play a pivotal role in the damage caused to our planet. However, not all emissions are the same, and understanding their various types is essential to effectively combat climate change. Among these emissions, Scope 3 emissions hold a significant position due to their indirect nature and the challenges associated with accurately measuring them. In this article, we'll break down the key points from a 2022 article titled "Supply-chain data sharing for scope 3 emissions" by Aurel Stenzel and Israel Waichman, focusing on making the concepts more accessible and understandable.

Differentiating Between Direct and Indirect Emissions

Emissions from production processes can be classified as either direct or indirect. Direct emissions are those that are produced by the reporting entity itself, like the smokestack emissions from a factory. Indirect emissions, on the other hand, are associated with the products themselves as raw materials go through various stages in the supply chain. The GHG Corporate Protocol provides a standardised way to define these types of emissions. It labels Scope 1 emissions as direct emissions, Scope 2 emissions as those related to energy generation, and Scope 3 emissions as all other indirect emissions along the supply chain.

Understanding Scope 3 Emissions

Scope 3 emissions are quite complex. They encompass all the emissions tied to the supply chain, including those from purchased goods, transportation, waste, employee commuting, and more. Surprisingly, these Scope 3 emissions make up a substantial portion of a company's total carbon footprint, averaging around 84%. This means that the impact of these indirect emissions on the environment is enormous, highlighting their importance in sustainability efforts.

The Importance of Accurate Reporting

Accurately measuring Scope 3 emissions is crucial for several reasons. It helps companies understand their environmental impact better, identifies areas where pollution can be reduced, and enhances transparency and accountability. Interestingly, while measuring and reporting Scope 1 and Scope 2 emissions are required, reporting Scope 3 emissions remains optional. However, this presents a problem as Scope 3 emissions constitute a significant majority of a company's carbon footprint, making up about 84% on average. In some industries, this number can be even higher. This gap in reporting is a concern as it hinders effective environmental action.

Benefits of Reporting Scope 3 Emissions

Why should companies bother with reporting Scope 3 emissions? The benefits are manifold. First, reporting these emissions increases transparency and allows companies to identify points of intervention for pollution reduction. It also fosters accountability, as firms are held responsible for their emissions. Moreover, reporting can lead to cooperative actions among companies, enhancing environmental efforts collectively. Additionally, sharing emissions data can lead to consumer pressure. When consumers are aware of the carbon footprints associated with products, they might make more sustainable choices, encouraging companies to adopt greener practices.

Benefits of Reporting Scope 3 Emissions

While the digital era has made data collection easier, sharing emissions-related data remains a challenge. Several obstacles contribute to this difficulty:

• Legal and Regulatory Challenges: Navigating the legal landscape is tough due to contractual limitations and varying data localisation measures across different countries. Ambiguous regulations and potential legal implications discourage firms from investing in emission data sharing.
• Interoperability Issues: Lack of interoperability means data measurement methods aren't standardised, and there's no consistent infrastructure for data exchange between different IT systems. This inconsistency makes creating a unified emission footprint challenging.
• Data Privacy Concerns: Privacy concerns arise when sharing detailed emission data, as it might expose sensitive information about production processes and supply networks. Companies fear this could lead to competitive disadvantages or compromise proprietary data.

Overcoming the Challenges

To tackle these challenges, collaborative efforts and innovative solutions are necessary:

• Legal and Regulatory Solutions: Governments and regulators can make Scope 3 emissions reporting mandatory, clarify regulations, and provide incentives for firms to embrace data sharing.
• Interoperability Initiatives: Initiatives like the Partnership for Carbon Transparency (PACT) aim to establish consistent methods for calculating emissions and provide technical infrastructure for data sharing.
• Data Privacy Solutions: Data trusts and advanced encryption technologies offer ways to protect data privacy while enabling effective data sharing. These solutions ensure privacy while promoting transparency and cooperation.

"To tackle these challenges, collaborative efforts and innovative solutions are necessary."

Conclusion

Scope 3 emissions are a vital aspect of a company's environmental impact, and accurate measurement hinges on overcoming challenges related to data sharing. Collaborative initiatives, standardised methods, and innovative privacy-preserving technologies are key to successful data sharing and effective emission reduction efforts. Sharing primary emission data empowers sustainable decision-making, enables optimisation, and paves the way for a greener future in the world of supply chains.

Frequently Asked Questions

1. What are Scope 3 emissions?

Scope 3 emissions encompass all indirect emissions within a company's value chain that are not included in Scope 2 (indirect emissions generated by the production of purchased energy).

2. Why are Scope 3 emissions important?

Scope 3 emissions constitute a significant share of many companies' carbon footprints, making them essential to include in emissions reporting and reduction efforts.

3. How much emissions occur in Scope 3?

Scope 3 emissions account for approximately 88% of greenhouse gas emissions across sectors.

4. How are Scope 3 emissions calculated?

Companies calculate Scope 3 emissions through a process known as carbon accounting.

5. Why are Scope 3 emissions difficult to calculate?

Collecting data for value chain carbon calculations can be challenging as these emissions occur outside a company's owned operations. Automated carbon accounting tools can expedite this process.

6. How do I reduce emissions in Scope 3?

To reduce Scope 3 emissions, it is crucial to first comprehensively and accurately account for them. Subsequently, businesses can initiate reduction efforts, often by engaging their suppliers in emissions reduction initiatives.

7. What is CSRD reporting, and how does it relate to Scope 3 emissions?

CSRD stands for Corporate Sustainability Reporting Directive, and it encompasses various sustainability-related reporting requirements, including Scope 3 emissions. Compliance with CSRD requirements may necessitate robust tracking and reporting of these emissions.

8. How does the GHG protocol classify Scope 3 emissions?

The Greenhouse Gas Protocol categorises Scope 3 emissions into various upstream and downstream sources, providing a detailed framework for understanding and managing these emissions.

9. What is the difference between carbon neutrality and net zero?

Carbon neutrality typically refers to balancing the emissions a company generates with emissions reductions or offsets. Net zero, on the other hand, entails achieving a balance between emissions produced and emissions removed from the atmosphere, often involving more aggressive emissions reductions.

10. How can a company work towards achieving net zero emissions in Scope 3?

Achieving net zero emissions in Scope 3 requires a multifaceted approach that involves reducing emissions across the value chain, engaging with suppliers, adopting sustainable practices, and potentially offsetting remaining emissions through reforestation or carbon removal projects.

11. What is the significance of TCFD Assessment in managing Scope 3 emissions?

The TCFD (Task Force on Climate-related Financial Disclosures) Assessment helps companies assess and disclose their climate-related risks and opportunities, including those associated with Scope 3 emissions. It provides a structured framework for understanding climate impacts on a business's operations and finances.

12. How can Supplier Questionnaires aid in addressing Scope 3 emissions?
