Here is the IPCCs detail of ghg gas emissions [1] The gross global warming effect of pollutants that you are mentioning is low compared to CO2. Methane emissions amount to around 16% of CO2(e) emissions, and NOx emissions amount to around half of methanes. Refrigerants and others about 2% so far, though they could get worse if not better controlled (which seems to be drawdowns case). The IPCC highlights CO2 because it is the main problem which has to be dealt with.
