LNG improves air quality
LNG does not only reduce greenhouse gas emissions but also air pollutants.
The rapid growth of cities is focusing attention on the environment and health impacts associated with air pollution from electricity generation, particularly when power plants are located close to urban centres.
In power generation, replacing coal with gas in electricity production is a must, as it is the most effective way to quickly reduce pollutant emissions such as SOx, NOx and particulate matters, by up to 99%.
In the industrial sector, displacing coal with natural gas can make a significant contribution to lowering greenhouse gas emissions and improving air quality.
In China, for example, a major policy programme to substitute coal boilers with natural gas boilers in North East China allowed to improve air quality of air in the Beijing region and to decrease the volume of air pollutants by 80% over the last 5 years. As Beijing gas demand was boosted, air pollution was dramatically and quickly reduced.
In the transport sector, LNG in maritime and road transport can quickly improve air quality in ports and cities, since it provides a significant emission reductions compared to conventional fuels – particularly in heavy duty road transport and shipping which are the most difficult to electrify.
