Clean water is fairly distinct from climate change. Greenhouse gasses are mostly harmless aside from their warming effect, and the stuff that makes air and water unhealthy doesn’t warm the planet.

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.
