Toplogredni plini - Količinsko določanje in poročanje o emisijah toplogrednih plinov, ki nastanejo pri dejavnostih prometne verige (ISO 14083:2023)

Predlagani standard bo določil skupno metodologijo za kvantifikacijo porabe energije in izpustov toplogrednih plinov (GHG) pri transportu (transport blaga, oseb ali obojega).
Določil bo splošna načela, opredelitve, meje sistema, računske metode, pravila porazdelitve in podatkovna priporočila, njegov cilj pa je spodbujati standardizirano, skladno, kredibilno in preverljivo poročanje v zvezi s porabo energije in izpusti toplogrednih plinov pri vseh načinih transporta. Prav tako bo vključeval primere o uporabi načel in privzetih podatkov o emisijah in porabi, ki se jih priporoča ob odsotnosti razpoložljivih specifičnih podatkov.
Potencialni uporabniki tega predlaganega standarda so osebe ali organizacije, ki morajo pri poročanju rezultatov merjenja porabe energije in izpustov toplogrednih plinov pri transportnih storitvah uporabiti standardizirano metodologijo, še posebej:
• izvajalci transportnih storitev (prevozniki blaga ali oseb);
• organizatorji transportnih storitev (prevozniki, ki sodelujejo s podizvajalci transportnih storitev, špediterji);
• uporabniki transportnih storitev (pošiljatelji in potniki).
Obseg izračuna toplogrednih plinov mora vključevati emisije področij uporabe 1–3 s pristopom »od vira do kolesa«. Zato mora izračun porabe energije in emisij toplogrednih plinov zajemati energijske postopke na začetku dobavne verige (npr. ekstrakcija/proizvodnja goriva, prevoz in rafiniranje) in postopke na mestu uporabe.
S sklicevanjem na področja uporabe 1–3 v skladu s protokolom za toplogredne pline »Računovodski standard in standard poročanja za vrednostne verige podjetij (področje uporabe 3)« mora novi standard ISO prav tako vsebovati opredelitev vlog in obsegov poročanja zgoraj navedenih akterjev v transportni verigi.

Overview

EN ISO 14083:2023 (EN ISO 14083:2023 / ISO 14083:2023) provides a common methodology for the quantification and reporting of greenhouse gas (GHG) emissions from transport chain operations for both passengers and freight. Endorsed by CEN and superseding EN 16258:2012, the standard covers all transport modes (air, sea, inland waterway, road, rail, pipelines, ropeways/cable cars) and explicitly includes hub operations (e.g., ports, terminals, airports) and pipeline transport in system boundaries.

Key technical topics and requirements

• Scope and system boundaries: Defines which transport operations and hub processes are included, optional processes, and application of cut-off criteria.
• Quantification principles: Guidance on converting energy carrier data (fuel, electricity, refrigerants, leaks) into GHG emissions using global warming potential and appropriate emission factors.
• Activity calculation: Methods for calculating transport activity distances (actual, or straight/fixed distance when appropriate) and use of a Distance Adjustment Factor (DAF) when activity distance is unavailable.
• Data hierarchy and quality: Preference order for data sources - primary data for transport operations, then modeled/secondary data, and default values when necessary.
• Allocation rules: Procedures to allocate emissions when passengers and freight share vehicles, and optional differentiation by passenger travel class.
• Reporting metrics: Reporting at organizational, transport chain, or transport chain element levels; required outputs include total GHG emissions, vehicle/hub use emissions, energy consumption and emission intensities.
• Optional elements: Guidance for optional quantification of black carbon and handling of carbon offsetting/GHG trading within results.
• Terminology alignment: Updates over EN 16258 - e.g., TTW/WTT/WTW terms mapped to vehicle use, vehicle energy provision and total.

Practical applications and users

Who uses ISO 14083:

• Transport operators, logistics providers, freight forwarders and carriers
• Shippers, supply chain and sustainability teams calculating Scope 3 transport emissions
• Ports, airports and terminal operators conducting hub emission inventories
• Policymakers, auditors and consultants for benchmarking and regulatory compliance

Typical uses:

• Standardized carbon footprinting of transport services and logistics chains
• Internal and external GHG reporting, supplier reporting requirements, tendering and RFPs
• Performance benchmarking, decarbonization planning, and validating sustainability claims

Related standards

• ISO 14064 series (GHG inventories and reporting)
• EN 16258:2012 (superseded)
• National/international emission-factor databases and sectoral guidance (as referenced by ISO 14083)

Keywords: ISO 14083, EN ISO 14083:2023, greenhouse gases, GHG emissions, transport chain operations, transport emissions, quantification, reporting, transport footprint, hub operations, emission factors.

Introduction
This document provides requirements and guidance for the quantification and reporting of greenhouse
gas (GHG) emissions for transport chains for passengers and freight.
This document provides such a calculation with its related reporting. It specifies how to source data as
input for the calculation, taking into account that transport operations vary hugely, from multinational
organizations operating multiple transport modes to deliver transport services across the globe,
through small local operators delivering a simple service to a single user; hence this document has
adopted a structure to make it widely applicable. To ensure that values for GHG emissions that result
from vehicle and hub operation and associated energy provision are considered, this document takes
into account the GHG emissions associated with production and distribution of energy (including, for
example, production and distribution of liquid energy carriers or grid transmission of electricity). As
a result, calculation results can enable a consistent comparison of possible different energy carriers
by transport service operators, users and any other interested parties. Calculation results are only
directly comparable if all options chosen are internally consistent.
