In general, the fall in emissions during the 1990s was due to a decrease in total fuel consumption caused by the transformation of the national economy, increased energy efficiency and a switch from solid fuels and liquid fuels to natural gas and biomass fuels. In recent years, emission levels have remained relatively stable.

The energy sector is the main source of sulphur dioxide emissions in Latvia.

Domestic heating and the use of solvents and other products represent significant sources of volatile organic compounds (VOCs).

The largest proportion of nitrogen oxide emissions originates from the transport sector (particularly road transport) and the number of registered motor vehicles per 1 000 inhabitants continues to increase (Figure 7).

Almost all NH3 emissions originate from agricultural activity.

Overall, air pollution decreased between 1990 and 2005 − SO2 by 96 %, VOCs by 34 %, and NH3 by 70 % (Figure 8). During this period, the relative influence of the transport sector on nitrogen oxide emissions grew, while the influence of energy production fell by almost 50 %[1].
