A carbon footprint is the amount of greenhouse gases caused as a result of human activities, typically expressed in equivalent tons of carbon dioxide.

Waste Concern’s work and initiatives have resulted in the reduction of the following amounts of green house gases (this calculation excludes the CDM project in Dhaka):

Year	GHG Reduced ( T of CO2e/Year)	Value of GHG Saved ( US $)
2001	1267	12,695
2006	17908	179080
2001-06 ( Total)	62,200	622,000

Note that from 2001 to 2006, there was a reduction of 62,200 tons of carbon dioxide annually. The value of green houses saved for the same time period was US $622,000.
