How sustainability goals become reality
Renewable Natural Gas (RNG) is a transportation fuel made from organic waste. It drastically reduces carbon emissions by an average of 300% versus diesel, and at a fraction of the fuel cost. Unlike conventional natural gas, RNG is not a fossil fuel and does not involve drilling.
Clean Energy pioneered RNG as a vehicle fuel in the U.S. and we continue to be North America’s largest provider of RNG for the transportation industry.
Greenhouse gases are bad.
We make them something good.

Livestock manure and landfills account for 27% of methane emissions in the U.S.
THIS IS THE SOURCE OF OUR RNG.When organic matter decays, it naturally produces methane: one of the greenhouse gases most detrimental to the environment. By capturing the methane, we prevent it from entering and damaging the atmosphere. Then, we turn it into the cleanest fuel in the world.
The transportation industry is responsible for 28% of the total greenhouse gas emissions in the U.S.
Our ultraclean RNG powers heavy-duty trucks and buses, replacing dirty diesel and gasoline. When combined with the latest natural gas engines, RNG is a zero emissions solution certified by the EPA and the California Air Resources Board.

Keeps carbon out of the atmosphere.
And your green fleet on the road.
The beauty of RNG is that it reduces carbon on two fronts: at the source where it's made and on the road.
That’s why it’s able to achieve such a low carbon intensity rating. RNG is the only alternative fuel that can avoid more emissions than it generates.

“It’s here now, it works, and it’s already near-zero, in some cases sub-zero. And the technology is relatively inexpensive compared to some of the alternatives.”
