As the urgency to combat climate change grows, so does the scrutiny on how companies measure and report their carbon footprints. Central to this is the challenge of double counting in Scope 3 emissions. While complexities exist, they should not be used as a smokescreen to delay action or obscure true environmental impacts.
Understanding Scope 3 Emissions:
Scope 3 emissions capture all indirect emissions in a company's value chain, excluding direct operations (Scope 1) and purchased electricity (Scope 2). Given their broad nature, they often represent the bulk of a company's carbon impact.
The Double Counting Dilemma:
- Nature of Supply Chains: Interconnected supply chains can lead to emissions being counted multiple times across entities. However, this complexity should not deter companies from reporting or taking responsibility.
- Financial Institutions' Challenge: For financial entities financing multiple supply chain members, there's a risk of inflating perceived carbon risk. But this challenge is not insurmountable and should not be an excuse for inaction.
The Imperative of Transparent Reporting:
Despite the complexities, underreporting or misreporting Scope 3 emissions is not acceptable. Every company must strive for transparency, even if perfection is initially out of reach.

The Way Forward:
- Prioritize Action: The focus should always be on reducing emissions and making real-world impacts, rather than getting bogged down in reporting intricacies.
- Standardized Guidelines: While industry bodies work on standardized guidelines, companies should proactively adopt best practices and be transparent about their methodologies.
- Leverage Technology: AI and machine learning can help in mapping supply chains and estimating emissions, making the task more manageable.
- Embrace Fair Allocation: Techniques like the Shapley Value allocation can ensure fair emission allocation across the supply chain, promoting collective responsibility.
The Shapley value concept
The Shapley value is a concept in cooperative game theory that assigns a value to each player in a game to represent their fair share of the total value based on their contribution. It ensures that each player's payout or cost allocation reflects their marginal contribution to the game, considering all possible combinations of players. The Shapley value ensures that no player is overcompensated or undercompensated for their contribution, providing a balanced distribution of the total value among all players.
While the double counting issue in Scope 3 emissions is a genuine challenge, it should never be a reason for companies to delay action or obfuscate their true environmental impact. In the race against climate change, transparency, accountability, and immediate action are the only acceptable paths forward.
