VW's emission cheating produced more Nitrogen Oxide emissions and less carbon dioxide emissions than if the vehicles ran the same in normal conditions and test conditions. In a nutshell, the engines ran hotter while cheating, which naturally increases fuel efficency and nitrogen oxide production.
So, it was bad for breathing, but good for climate change. Except that remedying the situation was probably a lot of emissions.
