Fossil fuel percent of [its] weighted emissions in 1998. Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals. According to Environment Canada: "The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit
Environmental issues in Georgia pollutants monitored in Georgia include particulate matter (total suspended particulates [TSP]), carbon monoxide (CO), nitrogen oxides (NO2, NO), and sulfur dioxide (SO2). In Georgia the public transport system is not sufficiently developed. A significant proportion of the population uses private vehicles as the preferred mode of transport. The number of private vehicles has grown rapidly over the past decade and has almost doubled in the last five-year period. Traffic has increased followed by industrial sources. The country has seen a sharp rise in the number of old, dirty diesel vehicles on the road over the last decade and pollution testing
