You're doing it for the emissions.

I've got a few things on my mind.

We always had the intent to use that feature.

It was unbelievable. It was much brighter than expected with many diagnostic emissions.

In some experiments we get a 70 percent decrease (in methane emissions), which is quite staggering.

The chances are very good that it's not the emissions we know about that are really bothering people, but rather the compounds that result when the emitted chemicals react with ozone. That could be quite significant in urban areas like Atlanta that have high levels of ground-level ozone.
