   Emission Factors Portal

Welcome to the Emission Factors Portal

This portal serves as a central hub for reviewed databases related to **emission factors**. Here, you'll find a **summary table** of key databases, with links to detailed reviews.


Emission Factors Database Summary

Database Name Database Type Regions Free or Paid Description
Ecoinvent Activity-based Global Paid Comprehensive life cycle inventory data for carbon footprinting and sustainability assessments.
DEFRA Emission Factors Activity & spend-based UK Free Official UK government emission factors for company reporting.
GREET Model Activity-based USA Free Argonne National Laboratory’s tool for transportation emissions and life cycle analysis.
EXIOBASE Spend-based Global Free Detailed multi-regional input-output database for environmental assessments.
GHG Protocol Database Activity & spend-based Global Free A widely used emissions database for corporate and product carbon accounting.
Agribalyse Activity-based France Free Managed by the French Environment Agency (ADEME), is a public database that provides detailed life cycle assessment data for agricultural and food products.
Base Empreinte Activity & spend-based France Free Managed by the French Environment Agency (ADEME). It focuses on carbon emissions related to various sectors, providing emission factors for a wide range of activities, products and services.
EEA Activity-based Europe Free Primarily focussed on emission factors for air pollutants and greenhouse gases in the European Union.
Global Logistics Emissions Council (GLEC) Activity-based Global Free Globally recognized emission factors for freight transportation; covering road, rail, air, sea, and inland waterways.
UBA Activity-based Germany Free The Umweltbundesamt (UBA), Germany’s Environment Agency, provides emission factors for various sectors, including energy, industry, transport, and agriculture.
OEKOBAUDAT Activity-based Global Free OEKOBAUDAT is a German government-managed database for environmental impacts and emissions associated with construction materials and buildings.
EPA GHG Emission Factors Hub Spend-based USA Free Regularly updated and easy-to-use set of default emission factors for organizational greenhouse gas reporting.
CARB Activity-based Global Free CARB maintains a list of the Global Warming Potential for the most common refrigerants regulated under their Refrigerant Management Program
Carbon Ditch Spend-based Paid DitchCarbon is a platform designed to automate the collection and reporting of Scope 3 emissions data.
WRAP Activity-based Global Free Provides a repository of secondary emission factors for food and drink that organisations can use for scope 3 reporting.
PCAF Activity-based Europe Free It provides a standardized methodology for measuring and reporting financed emissions in the financial sector.
Netherlands Enterprise Agency Activity-based Netherlands Free List of emission factors including Tank-to-Wheel, Well-to-Tank and biogenic emissions
EORA Multi-regional Input-Output (MRIO) Global Paid MRIO model that provides a time series of high-resolution IO tables with matching environmental and social satellite accounts for 190 countries.
Government of Canada Government Database Canada Free The EFs are more tailored to national reporting (following IPCC guidelines) than organisational reporting.
BEIS Activity & spend-based UK Free In addition to fuels and UK electricity EFs, it also provides data sets relevant to Scope 3 categories.
AIB Activity-based Europe & UK Free AIB publishes annual residual grid emission factors for European countries aligned to the reporting requirement under the market-based approach in the GHG Protocol scope 2 guidance.
Green-e Activity-based USA Free Green-e plays a role in certifying renewable energy and carbon offsets.
IEA Activity-based Global Paid Provides international electricity emission factors.
IPCC Activity-based Global Free To be used in calculation of anthropogenic emissions by sources and removals by sinks of greenhouse gases.
EEI Activity-based USA Free Database of market-based EFs for electricity suppliers in the US
ICE Activity-based UK Free The Inventory of Carbon and Energy (ICE Data base) is an embodied carbon database for building materials.
Plastics Europe Eco profiles Activity-based Europe Free Lifecycle inventories and Environmental Production Declarations for a large number of different plastics.
eGRID Activity-based USA Free eGRID separates electricity generation and emissions across several aggregation levels: Generator, Plant, State, and Subregion. 
FIGARO Spend-based Europe & G20 Free Includes aligned Input Output Tables, Supply-Use Tables, Globalisation Indicators and Environmental footprints (GHG emissions).
Carbon Border Adjustment Mechanism (CBAM) Default Values Activity-based Global Free & Paid A policy tool implemented by the EU for carbon-intensive goods imported into the EU.
