I'm biased, but I feel like if they really cared about the environment they would encourage licensing this instead of keeping it to themselves.

Patenting often precludes licensing. Lowering fuel costs is not synonymous with environmental concern.

Don't you mean "precedes"? You can't license something you don't have the rights to.

Who said they cared about the environment? They wanted lower fuel costs to save themselves money, which makes perfect sense.

The article mentioned carbon dioxide output: "the company overhauled the design to address rising fuel costs and cut carbon dioxide emissions"

Though I imagine the fuel costs are a primary consideration and the environmental aspect is mostly there to push press opportunities.
