Sources of real data are precious and I just wanted to create place to link sources of information about greenhouse gas emissions. If you know of any other good sources of data, do let me know.
EDGAR (Emissions Database for Global Atmospheric Research)
This is a source of data on emissions of a wide range of greenhouse gases categorised by year, by geographic region, and even available on a geographic grid. One needs to register (free) to download raw data, but a number of useful graphs are available – like the one at the hea dof this article, or the geographically linked data below.
CDIAC (Carbon Dioxide Information Analysis Center)
This is a source of data on emissions of a carbon dioxide run by the US department of Energy. It also includes the World Data Center for Atmospheric Trace Gases. It includes a very nice frequently asked questions page. It can often take a lot of clicks to get to the data one needs – especially if one isn’t sure before hand exactly what one is looking for. This site was the source of the recent blog about annual oscillations in atmospheric carbon dioxide concentration
WMO (World Meteorological Organisation Greenhouse Gas Bulletin)
Authoritative annual summary of the state of current research on Greenhouse gases. The current summary (November 2010) can be found here.
