CEDA CLIMATE Technology Overview

CEDA CLIMATE covers Greenhouse Gas Emissions factors for 480 US commodities and services and is the underlying data source for Climate Earth Revenue Based and Expense Based Assessments. CEDA 3.0 covers 1344 environmental interventions including such factors as toxins, and land and water use.

CEDA 3.0 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

The CEDA 3.0 database has been widely used for various policy analyses including the Environmental Impact of Product (EIPRO) study of the European Commission. Read more here: http://www.jrc.es/publications/pub.cfm?prs=1429 and here: http://ec.europa.eu/environment/ipp/pdf/eipro_summary.pdf .

CEDA was used for the Environmental Product Prioritization study of the Danish Environmental Protection Agency. More here: http://www.blackwell-synergy.com/doi/abs/10.1162/jiec.2006.10.3.73?cookieSet=1&journalCode=jiec.

CEDA was utilized in the Resources Conservation and Recycling Act (RCRA) vision study by the U.S. Environmental Protection Agency (EPA).

These studies greatly contributed advancing our understanding of key products and services that are of greatest environmental impacts in our society. CEDA 3.0 also played an important role in academic research programs on e.g., carbon footprints of services in the U.S., comparisons of personal carbon footprints of the U.S. and Japan, and quantification of uncertainties in Life Cycle Assessment (LCA). Some of these research results have been widely publicized through, e.g., the Washington Post and the Science News.

Components of CEDA

CEDA CLIMATE comprises three main database modules: (1) an economic input-output database module, (2) a climate intervention database module, and (3) a characterization factor database module for climate impact assessment.

The input-output database module is derived from a variety of economic statistics, including 1998 US make and use accounts, the 1992 US capital flow matrix, a standard comparison table between US Standard Industry Classification (SIC) codes and the input-output industry codes of the US Bureau of Economic Analysis (BEA), and producer’s price change data from the US Bureau of Labor Statistics (BLS). The input-output data module contains information on the structure of inter-industry exchanges of materials and energy throughout

The environmental intervention database module contains information on generation of 1344 environmental interventions. It is derived from greenhouse gas emissions and sinks data, and relate to over 480 commodities produced in the US. The environmental interventions compiled in CEDA CLIMATE are the main driving causes of global warming.

The characterization factor database module contains characterization factors that allow users to aggregate environmental interventions into environmental impact scores. The selected impact assessment methods for CEDA CLIMATE are limited to Global Warming Potentials (GWPs).
