The Energy and Carbon Emissions Inventory Database (ECDB) is a program and associated data base designed to display the energy use, carbon emissions, and resulting energy and carbon intensities of the world and of the top 27 carbon-emitting nations (representing approximately 80% of global emissions).
Energy data have traditionally been reported by organizations in different units, using different energy equivalences for hydroelectric and nuclear power, and including different sources of energy (e.g. from municipal and industrial wastes). Similarly, accounting methods also differ for international inventories of carbon dioxide (CO2) emissions. These important inventory uncertainties often go unnoticed and can reduce the accuracy of scientific research based on them and could make policies less effective. The ECDB allows for the direct comparison of original reported energy and carbon emissions of the major international inventories and also allows harmonized comparisons across inventories in terms of categories covered as well as statistical accounting convention adopted.
The ECDB clarifies the differences and helps to reconcile discrepancies among major international energy and carbon emissions inventories.
The ECDB was compiled by IIASA and now covers the period of 1971 to 2012. It is available online for download for free.
The data base, its underlying sources and the implications for energy and carbon inventory uncertainty are documented in two publications (Macknick, 2009 and Macknick, 2011)
The ECDB was updated in 2013 using the same methodology and major energy and carbon emission inventory sources as reported in the peer-reviewed Macknick (2011) publication
Set out in simple Excel spreadsheet form, the ECDB consolidates energy and carbon emission inventories and allows users to view all reporting inventories side-by-side. Users can thus compare original data and also harmonize different inventories using consistent accounting frameworks.
Energy statistical data from the four international energy statistics available are integrated into ECDB, including: the International Energy Agency (IEA), the US Energy Information Administration (EIA), and BP plc. The previous inventory also included energy statistics from the United Nations, however these are not included in this fast-track ECDB update.
ECDB integrates five carbon dioxide emission inventory datasets: IEA’s Sectoral and Reference Approaches, the EIA, the Carbon Dioxide Information Analysis Center (CDIAC), and the Emissions Database for Global Atmospheric Research (EDGAR).
The ECDB has three main functions.
The Energy and Carbon Database is the first publically available tool that documents the uncertainties in energy and carbon emission statistics and inventories and allows to users to reconcile at least partly different inventory data. It was developed for the purposes of model calibration and for an assessment of potential impacts of uncertain emission inventory data on carbon markets. The ECDB was created and developed by Jordan Macknick in 2009 and covered the period 1970 to 2007. An update including data up to the years 2011/2012 was completed in 2013 by Mathis Rogner at IIASA.
The ECDB was updated in 2013. In addition to updating numbers with the latest available data from the reporting institutions, the following changes were made:
