Autogas is an outstanding fuel for vehicles that must comply with increasing stringent emission requirements. Low emissions of particulates (PM), carbon monoxide (CO), nitrogen oxide (NOx), and non-burned hydrocarbons (HC) enable autogas to outscore conventional fuels and most alternatives for environmental benefits.

It also plays an important role in mitigating climate change, because it is among the lowest life-cycle greenhouse gas emissions of all commercially available fuels. Moreover, autogas is a non-toxic and non-poisonous fuel that will not contaminate aquifers or soil if spilled.

Autogas is simply a clean transportation fuel. Its impressive environmental benefits are influencing fuel choice decisions, and are rapidly driving increased use in many countries.

Compared to gasoline, autogas yields:

  • 50% less carbon monoxide
  • 40% less hydrocarbons
  • 12% less carbon dioxide
  • 35% less oxides of nitrogen
  • 50% less ozone forming potential
