The Structure of CEDA

Climate Earth's database is the Comprehensive Environmental Data Archive for Economic and Environmental Systems Analysis (“CEDA 3.0 Climate”).

CEDA Climate contains:

  1. an economic input-output database module
  2. a climate intervention database module
  3. a characterization factor database module for climate impact assessment
The input-output database module contains information on inter-industry exchanges of materials and services. This information is derived from a variety of economic statistics, including 1998 U.S. make and use tables, the 1992 U.S. capital flow matrix, a standard comparison table between U.S. Standard Industry Classification (SIC) codes and the input-output industry codes of the U.S. Bureau of Economic Analysis (BEA), and the U.S. producer price index data from the U.S. Bureau of Labor Statistics (BLS).

The environmental intervention database module is derived from greenhouse gas emissions and sinks data provided through industry surveys and related to over 480 commodities produced in the U.S. The environmental interventions compiled in CEDA Climate are the main driving causes of global warming.

The characterization factor database module contains characterization factors to aggregate different global warming gases into a single global warming potential value in terms of CO2-equivalents.

CEDA is unique, because unlike similar databases:
  • CEDA data sources are open and accessible
  • CEDA original data sources utilize a consistent time base
  • All updates include a complete audit trail
  • It is widely and positively peer-reviewed
  • CEDA 3.0 is utilized at the National Policy Level
CEDA is the trusted source for analyses by major institutions including:
  • European Commission
  • Danish Environmental Protection Agency
  • U.S. Environmental Protection Agency (EPA)
