While the volume if emissions made by transport and communication was approximate 0.7 million, the figure for domestic was slightly lower, at above 0.5 million. There was 2.1 million tons of emission procedure by other industries in this year.

Emissions from electricity, gas and water supply dropped dramatically, stood at around 0.5 million in 2007. At the same time, while the highest percentage was recorded in
other industries, at nearly 1.5 million, the figures for transport and communication and domestic was 0.7 and around 0.2 million respectively.
