Sometimes these two things go together, such as when replacing coal power plants with renewables. But sometimes they’re in opposition. For example, the Volkswagen emissions scandal was that they increased particulate pollution in order to decrease greenhouse gas emissions. In diesel engines, there’s a tradeoff between CO2 emissions and other emissions.
VW disputes this but I don’t know if they can be believed.
? The scandal was that they did it in testing only, so it passed the standards and they could turn it up in normal use.
