Outdoor Air Quality

Industries, households, cars and trucks emit complex mixtures of air pollutants, many of which are harmful to health. Of all of these pollutants, fine particulate matter has the greatest effect on human health. Most fine particulate matter comes from fuel combustion, both from mobile sources such as vehicles and from stationary sources such as power plants, industry, households or biomass burning.

Fine particulate matter is associated with a broad spectrum of acute and chronic illness, such as lung cancer, chronic obstructive pulmonary disease (COPD) and cardiovascular diseases. Worldwide, it is estimated to cause about 16% of lung cancer deaths, 11% of COPD deaths, and more than 20% of ischaemic heart disease and stroke. Particulate matter pollution is an environmental health problem that affects people worldwide, but low- and middle-income countries disproportionately experience this burden.

LPG is a proven solution to one of the most pressing problems, facing and ever more urbanised world: air pollution. Whether in the streets of Shanghai, Lagos, London or Bogota, deteriorating air quality has a serious and global impact on our health.


The traditional transport fuels: diesel and gasoline, are identified as a primary source of air pollution and ill-health, including the incidence of respiratory diseases and cancers. In China 70% of all air pollution is linked to transport emissions. Autogas is the most used alternative fuel and has a proven track record in reducing pollution levels.

Residential Space Heating

Measurements of total pollutant emissions produced by burning wood and coal show that these fuels produce around 150 times more carbon monoxide (CO) than LPG, per gigajoule of energy produced. Liquid fuels, such as kerosene, produce levels around 50% higher. The picture is similar for residential boilers.

In many locations solid fuel heaters and boilers produce enough pollution to directly affect the health of people in the community. Research clearly shows that cities where wood burning heaters are prevalent can have much higher ambient particle levels compared with other cities even though the non wood-burning cities had much lower population and traffic densities.

Electricity Generation

The most used fuel for power generation is still coal which potentially has an impact on air quality. In For decentralised power generation, unless they are fitted with sophisticated emission control technologies, generator sets can produce very high levels of high particle (PM) and oxides of nitrogen (NOx) emissions, with commensurably high health impacts.


Many industries still replay on fuel oil, heavy fuel oil or coal for heat or steam generation. Switching to LPG can have an immediate impact in reducing pollution levels.
