If I could answer your question, we know that the common sources are burning fossil fuels, for example. They make air pollutants and carbon dioxide. The common solutions could be in energy efficiency actions, where you reduce your individual usage of power--drive your car less. Also, some common solutions might be alternative sources of electricity, such as wind and solar power.
One of the things we have to be careful of in some of these solutions is that you can choose a climate change solution that might, for example, be burning wood, which is reportedly climate neutral. But burning wood creates a lot of air pollution, so it's perhaps a poor choice from an air quality point of view. You could have a solution for air pollution that doesn't fix climate change--for example, scrubbers on power plants, which take out sulphur, but they don't take out carbon dioxide.
