Scope 3 Reporting Software for Irish Businesses

Scope 3 emissions are the indirect emissions across your value chain. For Irish businesses in large corporate supply chains, Scope 3 data is increasingly expected by CSRD-reporting clients. GreenKPO measures and structures your Scope 3 emissions from existing Irish business data.

Scope 3 emissions cover all indirect emissions across a business's value chain, including purchased goods and services from suppliers. For Irish businesses in CSRD supply chains, Scope 3 data is increasingly expected by large clients for their own ESRS E1 reporting. GreenKPO helps Irish businesses measure Scope 1, 2 and 3 emissions from existing data and produce a structured, audit-ready Scope 3 inventory, typically within one working week.

Scope 1

Direct emissions from sources owned or controlled by the organisation. Includes gas, diesel, fuel oil and company vehicles.

Scope 2

Indirect emissions from purchased electricity, heat or steam. Calculated from electricity invoices.

Scope 3

All other indirect emissions across the value chain. The 15 GHG Protocol categories include purchased goods and services, business travel, employee commuting, upstream logistics and waste. Typically 70 to 90 per cent of total emissions.

Why Scope 3 matters for Irish businesses

Scope 3 emissions account for the majority of most organisations' total carbon footprint. Under ESRS E1, large Irish companies subject to CSRD must disclose their Scope 3 value chain emissions, which means they need to collect emissions data from their Irish SME suppliers. Even Irish SMEs not directly subject to CSRD are likely to receive Scope 3 data requests from their largest clients in the retail, financial services, pharmaceutical, technology and public sector industries.

How GreenKPO measures Scope 3 for Irish businesses

GreenKPO collects activity data across the Scope 3 categories most relevant to Irish SMEs, including purchased goods and services, business travel, employee commuting, and upstream logistics. Data is collected via structured surveys, financial ledger uploads and direct data entry with field-level validation. Every submission is timestamped and attributed. The KPOTrust immutable audit trail logs every Scope 3 data point with source, methodology and date. The output is a categorised Scope 3 inventory your client or auditor can rely on.

Starting with Scope 1 and 2 before moving to Scope 3

If your Irish business has not yet measured Scope 1 and 2 emissions, start there. GreenKPO calculates Scope 1 and 2 from your energy invoices and vehicle records within hours. Scope 3 is then layered on top. Most Irish businesses complete a full Scope 1, 2 and key Scope 3 inventory within one working week of onboarding. The result is a complete carbon baseline aligned to GHG Protocol and suitable for VSME Basic Module disclosure and CSRD supply chain requests.

  • Scope 1, 2 and 3 measured from a single platform
  • GHG Protocol Scope 3 category framework applied automatically
  • Structured vendor survey portal for upstream supplier data collection
  • Data quality split between measured and estimated values surfaced in the report
  • ESRS E1 and VSME aligned output for Irish supply chain disclosure
  • Immutable audit trail behind every Scope 3 figure

Common questions

What is Scope 3 and why do Irish SMEs need to measure it?
Scope 3 covers all indirect emissions across a business's value chain, including purchased goods and services, business travel, employee commuting and logistics. For Irish SMEs in CSRD supply chains, Scope 3 data is increasingly requested by large clients to complete their own ESRS E1 reporting. Starting to measure Scope 3 now means you can respond to those requests quickly and credibly.
What are the most important Scope 3 categories for Irish SMEs?
For most Irish SMEs, the most material Scope 3 categories are purchased goods and services (Category 1), business travel (Category 6), employee commuting (Category 7) and upstream transportation and distribution (Category 4). GreenKPO helps you identify and measure the categories most relevant to your business type and sector.
Do I need to measure all 15 Scope 3 categories?
No. The GHG Protocol allows companies to focus on the categories most material to their business. For most Irish SMEs, three to five categories will account for the majority of Scope 3 emissions. GreenKPO helps you identify the material categories and build your inventory from there, rather than attempting to cover all 15 at once.
How does GreenKPO collect Scope 3 data from my Irish suppliers?
GreenKPO includes a structured supplier survey portal that sends standardised data requests to your suppliers. Each supplier completes a validated form aligned to the VSME Basic Module environmental requirements. Submissions are timestamped and attributed. The data feeds directly into your Scope 3 Category 1 calculations.
How long does it take to produce a Scope 3 report with GreenKPO?
Most Irish businesses complete their first Scope 1, 2 and key Scope 3 inventory within one working week of onboarding. The platform uses existing business data such as energy invoices, vehicle records and financial information.
What is the difference between Scope 3 and VSME reporting?
Scope 3 is the GHG Protocol category covering indirect value chain emissions. VSME is the EU voluntary framework that includes Scope 1 and 2 emissions as its primary environmental disclosures. For Irish SMEs responding to supply chain data requests, producing a VSME Basic Module report with accurate Scope 1 and 2 data is typically the immediate priority. Scope 3 is then added as supply chain requests from clients become more detailed.
