Legal Framework: The CSRD Directive, ESRS E1 Standard, and the Definition of Scope 3

To understand the position of the SME sector, one must look at the EU’s legislative foundations. The CSRD directive mandates large public-interest entities and large enterprises to report sustainability information in compliance with the unified European Sustainability Reporting Standards (ESRS).

A pivotal document in the context of climate change is ESRS E1 (“Climate Change”). This standard requires reporting entities to disclose their comprehensive greenhouse gas (GHG) emissions profile, classified into three scopes in accordance with the GHG Protocol standard:

• Scope 1 (Direct Emissions): Emissions originating from sources owned or controlled by the enterprise (e.g., fuel combustion in technological processes, company-owned fleet).
• Scope 2 (Indirect Emissions): Indirect emissions resulting from the consumption of purchased electricity, heating, cooling, or steam.
• Scope 3 (Other Indirect Emissions): All other indirect emissions occurring within the value chain of the reporting enterprise—both upstream (at the supplier stage) and downstream (product use and end-of-life disposal by the end consumer).

According to ESRS E1 guidelines, if a materiality assessment reveals that Scope 3 emissions constitute a significant portion of the organization’s total carbon footprint (which exceeds 80-90% of the total sum in the manufacturing, construction, and logistics sectors), the corporation is legally required to report them and present corresponding reduction plans.

Market Pressure Mechanism: The Domino Effect in the Value Chain

Large enterprises mandated to reduce Scope 3 emissions cannot achieve their climate targets (Net-Zero targets) without close collaboration with their suppliers. This is precisely where a direct business dependency emerges for the SME sector.

Previously, corporations relied heavily on the spend-based method, estimating supplier emissions based on financial invoice values and sector-average emission factors. However, this method carries a vast margin of error and fails to demonstrate real, quantifiable decarbonization efforts.

Consequently, financial institutions, auditors, and corporate procurement committees now demand primary data — meaning the actual greenhouse gas inventory results of the respective subcontractor. An SME’s lack of operational readiness to provide this data results in:

1. A downgrade of the supplier’s rating in procurement and RFP processes.
2. Exclusion from tenders in favor of competitors who possess a verified Carbon Footprint of Product (CFP).
3. An increase in the cost of external capital, as banks scrutinize ESG risks in loan portfolios with growing stringency.

Characteristics of the VSME Standard as an EU Shield for the SME Sector

In response to the risk of bureaucratic paralysis and the fragmentation of commercial questionnaires dispatched by corporations, the EFRAG (European Financial Reporting Advisory Group) developed the VSME ESRS (Voluntary SME Environmental, Social, and Governance Standard).

The VSME is a simplified, voluntary standard designed for micro, small, and medium-sized enterprises not directly covered by the CSRD directive. Its primary objective is to establish a single, universally accepted reporting profile that an SME can present to any contractual partner, financial institution, or insurance company.

The VSME standard features a modular structure, enabling organizations to tailor their reporting depth to their corporate maturity:

1. Basic Module: Tailored for micro-enterprises. It is limited to fundamental non-financial metrics, requiring only key data regarding energy consumption and the calculation of Scope 1 and Scope 2 emissions.
2. Narrative Module: Focuses on disclosing the policies, targets, and actions undertaken by the company across environmental and social dimensions.
3. Business Partners Module: A critical element for suppliers. It incorporates supplementary metrics (including elements of Scope 3) that are most frequently required by corporations during Request for Proposal (RFP) processes.

Thanks to the VSME, smaller firms gain a transparent legal and methodological framework—knowing precisely which data points are material, thereby avoiding costly and redundant analyses.

Calculation Methodology: From Estimated Data to Primary Data

Reliable carbon footprint reporting under the VSME standard requires the application of recognized international emissions accounting standards, specifically the GHG Protocol Corporate Accounting and Reporting Standard.

The greenhouse gas inventory process within an SME is divided into three key methodological stages:

Step 1: Defining Organizational and Operational Boundaries

The enterprise must determine which plants, subsidiaries, or vehicle fleets are subject to emission consolidation (based on the criteria of operational or financial control).

Step 2: Mapping and Collecting Activity Data

Transitioning to a higher tier of accuracy demands the elimination of financial proxies in favor of quantitative data. This entails gathering information in physical units:

• kWh of electricity consumed,
• Liters or cubic meters of stationary and mobile fuel combusted,
• Kilograms or metric tons of purchased raw materials (e.g., steel, plastics).

Step 3: Selecting Appropriate Emission Factors

Each collected quantitative data point must be multiplied by a scientifically verified emission factor derived from certified databases (such as DEFRA, ecoinvent, or specific national factors like KOBiZE for grid electricity).

GHG Emissions (CO2e) = Activity Data x Emission Factor

Technology in the Service of Compliance: The Audit-Ready Standard in the NEOGAGE Ecosystem

Manual management of emission factor databases and attempts to balance greenhouse gases using Excel spreadsheets introduce a high risk of methodological errors. Faced with stringent verifications by auditors from large corporations, process automation becomes the key to success.

The NEOGAGE technological ecosystem (including the NEOGAGE Carbon Footprint modules and the dedicated NEOGAGE ESG application) aligns directly with EU data auditability criteria:

• Compliance with the GHG Protocol and VSME: The system’s calculation algorithms are continuously updated and aligned with the latest EFRAG and GHG Protocol guidelines, eliminating the risk of utilizing obsolete factors.
• Audit-Ready Standard (Audit Trail): Every data point entered into the system (whether manually or via API integration with ERP/accounting systems) maintains a transparent history of origin. This allows external auditors or a client’s certification body to instantaneously trace the path from the raw source document to the final figure in the report.
• Supply Chain Optimization: The platform facilitates straightforward management of the data collection process from lower-tier subcontractors, standardizing inquiries and presenting results via clear executive dashboards.

Summary and Key Takeaways for Executive Management

The implementation of the CSRD directive and the VSME standard has irrevocably closed the era of estimating environmental impact by rule of thumb. The carbon footprint has emerged as the new currency in B2B business relations within the European Union. For SMEs, deploying a digital emissions management system is not an expense—it is a strategic investment in revenue security, the retention of critical commercial contracts, and the cultivation of a sustainable competitive advantage.

Digitalizing this process using dedicated platforms such as NEOGAGE minimizes administrative burdens and ensures a seamless transition through market verification processes.
