| 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. | |
