I have no idea how to account for the lessened cargo and towing capacity. If it's sufficient then it's sufficient, and if it wasn't the hypothetical buyer wouldn't have purchased it?

Anyway, it's true that CNG is no panacea with regard to the environment, but it is nonetheless represents a non-negligible improvement while also being cheap and nearly entirely domestically sourced. Per this arbitrarily picked analysis, CNG vehicles offer "an 18%-19% reduction in the overall life cycle environmental impact" relative to gasoline.

So there is a global benefit, albeit a small one. For the diesel proponents, note that they concluded "mineral diesel and petrol are equivalent (within confidence limits) regarding total life cycle environmental impact".

The leading technology in their analysis is electric, of course:

In those vehicle classes where available, the use of battery electric vehicles consistently result in the lowest overall environmental impact[,] always the case if renewable energy is used for recharging. In the best case, as compared to a petrol baseline, the overall environmental impact is reduced by over 70%.
The catch is in the phrase is at the start, "in those vehicle classes where available". Large, 4x4 BEVs with quick recharging ability akin to refueling a liquid or gaseous fuel vehicle are conspicuously unavailable on the market, and even I don't expect that to change any time soon.
