Standards We Align With
EcoFreight calculates freight transport emissions using established methodologies. Our API output is designed to support your sustainability and compliance reporting needs.
Methodology Alignment
Our emission calculations are built on recognized frameworks for transport emissions quantification.
The Global Logistics Emissions Council (GLEC) Framework v3.2 is our primary source for default emission factors across all transport modes: road, rail, sea, and air.
- Default emission factors for road, rail, sea, and air freight
- Well-to-Wheel (WTW) emissions approach covering full fuel lifecycle
- Vehicle type and size class differentiation
ISO 14083 provides the international standard for quantifying and reporting greenhouse gas emissions from transport operations. Our calculation approach aligns with its requirements.
- Activity-based emissions quantification
- WTW / TTW / WTT emission breakdowns
- Methodology references included in API responses
The GHG Protocol Corporate Value Chain Standard defines how to account for Scope 3 emissions. EcoFreight output maps to Category 4 (upstream transportation) and Category 9 (downstream transportation).
- Distance-based calculation method for Scope 3 reporting
- CO2e output suitable for Category 4 and Category 9
- Per-shipment and per-tonne-km intensity metrics
What the API Provides for Reporting
Each API response includes structured data designed to support compliance and sustainability reporting workflows.
Every calculation returns three emission values so you can report at the level of detail your framework requires.
- Well-to-Wheel (WTW) — Total lifecycle emissions including fuel production and combustion.
- Tank-to-Wheel (TTW) — Direct emissions from fuel combustion during transport.
- Well-to-Tank (WTT) — Upstream emissions from fuel production and distribution.
API responses include metadata about the calculation methodology, so you can trace results back to their source.
- Emission factor source — Which GLEC Framework v3.2 factor was applied.
- Transport mode and vehicle type — The specific category used for the calculation.
- Distance and cargo weight — Input parameters used in the calculation.
Regulations Where Our Data Can Help
Transport emissions data from EcoFreight can be a useful input for reporting under these regulatory frameworks. We do not provide full compliance solutions for any of these, but our calculations can support the transport emissions portion of your reporting.
CSRD requires large companies to disclose sustainability information, including Scope 3 transport emissions. EcoFreight can provide the freight emission calculations needed for the transportation component of your Scope 3 disclosure. For a step-by-step mapping, see the Scope 3 Category 4 CDP guide. Unfamiliar terms like WTW, TTW, or data quality tiers are defined in the freight emissions glossary.
US public companies disclosing climate-related risks may need to quantify GHG emissions from transportation. EcoFreight provides standardized, methodology-backed emission data that can serve as supporting documentation.
SB 253 requires large companies operating in California to report Scope 1, 2, and 3 emissions. For Scope 3 Category 4 and 9 (transportation), EcoFreight can supply the emission calculations using GLEC Framework v3.2 emission factors.
A Note on What We Are (and Aren't)
EcoFreight is a freight emissions calculation tool, not a compliance platform. We provide transport CO2e data based on the GLEC Framework v3.2 and aligned with ISO 14083. This data can be a valuable building block in your broader compliance and sustainability reporting, but it does not replace professional compliance advisory, third-party verification, or legal counsel.
We are not certified by or affiliated with any of the standards bodies mentioned on this page. Our calculations use their published methodologies and emission factors as reference data.
