Executive Summary
This report sets out the greenhouse gas (GHG) inventory of Greenfield Pest Solutions Pty Ltd for the reporting period 1 January 2025 – 31 December 2025, prepared in alignment with ISO 14064-1:2018 and the GHG Protocol Corporate Standard. Emissions are quantified using IPCC AR6 100-year global warming potentials and DEFRA 2024 emission factors, supplemented by AU DCCEEW 2024 grid factors for purchased electricity.
Scope 1
287.42 tCO₂e
Scope 2 (location)
64.18 tCO₂e
Scope 3 (selected)
142.07 tCO₂e
Gross total
493.67 tCO₂e
Removals from verified offset purchases total 12.00 tCO₂e, giving a net residual inventory of 481.67 tCO₂e. Biogenic CO₂ of 4.21 tCO₂e is reported separately and is not included in the scope totals, in accordance with ISO 14064-1 §8.2.
Organisational Boundary
The organisational boundary has been established using the operational control approach (ISO 14064-1 §5.1; GHG Protocol Ch. 3). All facilities, vehicles and equipment over which Greenfield Pest Solutions Pty Ltd has the authority to introduce and implement operating policies are included.
- Head office and operations depot — Sydney NSW
- Service fleet of 14 light commercial vehicles (12 diesel, 2 petrol)
- Field equipment — petrol foggers, blowers and battery sprayers
- Refrigeration plant servicing the chemical store
Subcontractor activity is reported under Scope 3 Category 1 (purchased goods and services) where directly procured by Greenfield Pest Solutions Pty Ltd.
Reporting Boundary
All Scope 1 and Scope 2 sources within the organisational boundary have been quantified. Scope 3 categories have been screened against materiality (5% threshold) and stakeholder relevance per ISO 14064-1 §5.2.3. The following categories are included:
- Cat 1 — Purchased goods and services (chemicals, consumables)
- Cat 4 — Upstream transportation and distribution
- Cat 5 — Waste generated in operations
- Cat 6 — Business travel
- Cat 7 — Employee commuting
Categories 2, 3, 8 and 9–15 have been screened and either deemed not material or not applicable. Justification is provided in Section 10 (Exclusions).
Methodology, Standards and Emission Factors
The inventory has been quantified following:
- ISO 14064-1:2018 — Specification with guidance at organisation level
- WRI/WBCSD Greenhouse Gas Protocol Corporate Standard (Revised Edition)
- WRI/WBCSD Corporate Value Chain (Scope 3) Standard
- IPCC AR6 (2021) — 100-year Global Warming Potentials, including CH₄ and N₂O
- UK DEFRA 2024 GHG Conversion Factors (mobile combustion, transport, waste)
- AU DCCEEW 2024 National Greenhouse Accounts (grid electricity factors)
- Supplier-specific Environmental Product Declarations where available
Activity data is sourced from internal accounting records, fleet telematics, utility invoices and supplier reports. Where measured data was unavailable, estimation methods are documented in Appendix A and the affected entries are flagged in the data quality assessment (Section 9).
Scope 1 — Direct Emissions
Direct emissions from sources owned or controlled by Greenfield Pest Solutions Pty Ltd:
| Source | Activity data | Emission factor | GWP | EF source | tCO₂e |

| Other process emissions | mixed | mixed | — | Internal records | 142.00 |
| Scope 1 subtotal | 287.42 | ||||
Scope 2 — Indirect Emissions from Purchased Energy
Reported using the location-based method. A market-based figure of 51.30 tCO₂e is also disclosed (reflects partial GreenPower purchase covering 18% of office consumption).
| Source | Activity data | Emission factor | GWP | EF source | tCO₂e |
|---|---|---|---|---|---|
| Purchased electricity — depot (NSW grid) | 78 400 kWh | 0.79 kg CO₂e/kWh (AU NSW 2024) | IPCC AR6 | DCCEEW 2024 NGA | 61.94 |
| Purchased electricity — admin office | 2 850 kWh | 0.79 kg CO₂e/kWh | IPCC AR6 | DCCEEW 2024 NGA | 2.25 |
| Scope 2 subtotal (location-based) | 64.18 | ||||
Scope 3 — Other Indirect Emissions
Material Scope 3 categories per the GHG Protocol Scope 3 Standard. Categories are screened annually for materiality.
| Source | Activity data | Emission factor | GWP | EF source | tCO₂e |
|---|---|---|---|---|---|
| Cat 1 — Purchased chemicals & consumables | 4 220 kg | product-specific | Mixed | Supplier EPDs / Ecoinvent v3.10 | 38.21 |

| Scope 3 subtotal | 142.07 | ||||
Biogenic Emissions and Removals
Biogenic CO₂ emissions of 4.21 tCO₂e arise from the combustion of biofuel blends (E10) in the petrol fleet. These are reported separately from the scope totals per ISO 14064-1 §8.2.
Removals total 12.00 tCO₂e and consist of verified carbon offset units retired during the reporting period (Gold Standard VER-2025-AU-0148; nature-based avoidance project, NSW). Retirement evidence is held on file.
Uncertainty Assessment and Data Quality
Each emission entry has been graded against a five-tier data quality framework (Tier 1 — directly measured / supplier-specific, through Tier 5 — estimated from spend). Aggregated portfolio quality:
| Source category | Tier | Estimated uncertainty |
|---|---|---|
| Fleet fuel | Tier 1 — measured | ±5% |
| Purchased electricity | Tier 1 — invoiced | ±3% |
| Refrigerants | Tier 2 — top-up records | ±15% |
| Chemicals (Scope 3.1) | Tier 3 — supplier EPD where available | ±25% |
| Employee commuting | Tier 4 — survey-based | ±35% |
Exclusions and Justifications
- Scope 3 Cat 2 (capital goods) — Excluded; no material capital additions during reporting period.
- Scope 3 Cat 3 (fuel- and energy-related activities not in S1/S2) — Quantified separately for disclosure but not aggregated to avoid double counting.
- Scope 3 Cat 8 (upstream leased assets) — Not applicable; no leased operational assets outside the operational control boundary.
- Scope 3 Cat 9–15 (downstream) — Not applicable to the service business model; the entity does not sell physical goods.
Comparison with Previous Reporting Period
Compared with the 2024 base year (533.16 tCO₂e), gross emissions in the current period have decreased by approximately 7.4%, driven by partial fleet electrification, improved route planning, and a 12% reduction in chemical consumption per service visit.
