CEDA – Comprehensive Environmental Data Archive
Name of sourceCEDA (“Comprehensive Environmental Data Archive”) 
ProviderWatershed Technology Inc. 
Summary textCEDA is an environmental Multi Region Input Output (MRIO) model designed to assist various environmental systems analyses, including life cycle assessments (LCA), carbon footprints, and sustainable spend analyses. CEDA offers 60,000 emissions factors that cover 400 industrial sectors and 148 countries.

Emissions results

The emission factors from the database are available in units of kg CO2e/$ or any other currency for 400 industry sectors and 148 countries. CEDA also provides a breakdown of GHG emissions by Scope (% of Scopes 1,2 and 3) and by type of greenhouse gas: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PCFs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3).

CEDA provides 2700+ environmental flows, most of which have been characterized by impact assessment methods such as TRACI and IMPACT+ into GWP, acidification, human health criteria, eutrophication, ozone depletion, eco-toxicity, smog, etc.
