Washington D.C.
The District of Columbia Air Quality Division has compiled greenhouse gas emissions inventories for the District of Columbia for the years 1990 and 2000. The Division has also prepared projected inventories for 2005 and the future year 2012. The Division chose the future year 2012 to coincide with the Kyoto Protocol's milestone year for setting greenhouse gas emissions reductions targets for developed countries, including the United States of America. If the United States were to ratify the Kyoto Protocol, the national target for the year 2012 would be to maintain emissions seven percent below that of the 1990 emissions levels.
