Frequently asked questions
Our calculation uses our measurement engine which is accredited by the Smart Freight Centre (SFC) to be in compliance with the GLEC Framework, meaning our carbon emissions measurement technology meets industry-leading standards for accuracy and reliability.
To receive this accreditation, a company must meet rigorous criteria and adhere to the GLEC Framework's guidelines. We consider various factors that contribute to emissions, such as fuel consumption, distance travelled, transport mode and specific activity data.
By following these standardised methods, we ensure that our calculations are accurate, consistent and comparable across different companies and industries.
Yes, Pledge is accredited by the Smart Freight Centre, in conformance with the GLEC framework. To qualify for the GLEC accreditation, our technology undergoes periodic quality assurance and validation reviews. We continuously update our measurement algorithms based on the latest research and industry best practices.
Pledge has one of the most comprehensive accreditation coverages on the market. Here’s a breakdown of the specific methodologies used for each mode of transport:
Sea: We employ the Clean Cargo Working Group methodology and the IMO methodology for sea freight. Default (GLEC Framework factors), carrier program (CleanCargo) and primary input data are supported. You can provide the IMO vessel number to enhance precision.
Air: We adopt a modelled approach based on the ICAO methodology when sufficient data is available. Otherwise, emissions factors from the GLEC Framework are used. We support both default and modelled input data types. To enhance precision, you can enter the flight number.
Road: We support all major input data types — default, modelled, carrier program (SmartWay) and primary. When no carrier or fuel consumption information is provided, we utilise emissions factors coming either from the GLEC Framework along with the GHG Protocol methodology or from the Handbook Emission Factors for Road Transport (HBEFA) , depending on the geography. To enhance accuracy, you can specify several vehicle details such as the class or the size of the vehicle, its emission standard, its load factor.
Rail: We utilise emissions factors from the GLEC Framework along with the GHG Protocol methodology. We support the default input data type.
Inland waterways: We employ emissions factors from the GLEC Framework along with the GHG Protocol methodology. We support the default input data type. To enhance accuracy, you can specify the type and size of barge.
Logistics hubs: We employ emissions factors from the GLEC Framework along with the GHG Protocol methodology. We support the default input data type. To enhance accuracy, you can specify the type of site.
Our calculation offers global coverage of all major modes of transport: Road, rail, air, sea, inland waterways and logistics hubs.
The Pledge platform harnesses powerful GIS capabilities, combining external geolocation and routing APIs with curated datasets, including UN/Locodes, ports and airports. It employs proprietary transport mode specific weighted network routing using diverse data sources such as OpenStreetMap, AIS data and ADS-B data for efficient multi-modal transportation.
Sea: Our maritime routing network incorporates the Oak Ridge National Labs CTA Transportation Network Group, Global Shipping Lane Network and World 2000 data, supplemented with lines derived from AIS data. It provides configurable routing avoidance options for canals, passages, straits, ice zones and piracy zones, as well as user-specified port calls, automatic actual voyage-specific port calls based on AIS data for historical voyages.
Road: We currently utilise HERE Maps API for worldwide locations with the ability to fallback to other services such as MapBox API, Google Maps API and AWS Location Service to overcome potential limitations in specific regions. Routes are analysed based on truck categories, characteristics and routing preferences such as ferry avoidance. Additionally, road categories (urban, rural, motorway), associated elevation profile and administrative zones are being returned.
Inland waterways: Our waterways routing network, based on OpenStreetMaps (OSM) data extracts, includes approximately 500k edges and in Europe, barges are routed based on the smallest CEMT class that the barge category can navigate. Outside of Europe, waterways are treated as CEMT class V by default.
Air: We use Great Circle Distance as the default measurement for airport distances. Stopovers can be manually added along the route by the user or be automatically extracted from flight numbers for historical journeys. Upcoming developments include maintaining a previously created air routing network consisting of 3,367 airports, 43,160 routes, and supplemented by no-fly-zone polygons, weighted by statistical frequency of flights from ADS-B data.
Rail: Our railway routing network, based on OpenStreetMap (OSM) data extracts, covers routes across all continents. Unlike road vehicles, trains cannot turn in arbitrary angles at any junctions. They can only turn in slight angles. These constraints have been integrated in our routing logic to get routes as realistic as possible.
Sea: We use vessel-specific emissions factors for approximately 1.8k containerships based on primary data, carrier-specific factors for CleanCargo members, and trade lane-specific factors derived from CleanCargo carrier averages. We also offer vessel-specific emissions factors for around 4k bulk, cargo and RoRo/RoPax vessels based on primary data, along with vessel type and size specific factors from the GLEC Framework and GHG protocol methodology for other scenarios.
Road: Emissions for vans and trucks outside North America can be calculated using fuel consumption data. When fuel consumption is not available, a model-based approach (HBEFA) considering class, load factor, empty running, region, road characteristics and more is used for European countries. The GLEC Framework factors and GHG protocol methodology are used for other non-European and non-North American locations. In North America, specific factors are used based on carrier codes, while other scenarios rely on category-specific factors from frameworks like EPA and NTM.
Inland waterways: We use barge type and size specific factors from the GLEC framework including 13 CEMT waterway classes and 16 barge types and sizes.
Air: We use a bottom-up model-based approach (ICAO methodology) that combines aircraft type, carrier, region and distances from routing, along with fuel emission factors from the GLEC Framework. We have access to emissions data from 9k IATA codes, 175 airline codes and 389 aircraft models. Aircraft type and size specific factors from the GLEC Framework and GHG protocol methodology are used for other scenarios.
Rail: We use traction (i.e. electricity vs diesel) and load characteristics (i.e. containerised vs average/mixed) specific factors from the GLEC Framework.
Logistics hubs: We use site specific factors from the GLEC Framework.
Our calculation complies with the European standards for calculating carbon emissions. Our calculator is SFC accredited in compliance with the GLEC Framework for global coverage of air, sea, road, rail, inland waterways and logistics hubs. As the ISO:14083 standard was developed in line with the GLEC Framework, our calculator is also ISO:14083 aligned.
