A website for a worthy cause that I've been helping out with in my 20% time has just gone live. From the UN blog post:
"UNFCCC emissions data visualized on Google Maps (7 July 2009)
The secretariat has cooperated with Google and the Danish government as hosts of COP 15 to display official UNFCCC greenhouse gas (GHG) emissions data for Annex I Parties using Google Maps. The user can now select on a world map total national GHG emissions/removals as well as emissions/removals from various sectors; absolute numbers (in Gg CO2 equivalent); or relative changes in emissions (in per cent compared to the base year level)"
