My money is on space sunshades.
While it would cost tens of trillions to make a sunshade by launching from Earth, making sunshades and launching them from the moon should be viable thanks to the lack of atmosphere and low gravity. Assuming that a few million tons of mass is enough to set up a space sunshade manufacturing station (and railgun launch rails) it should only cost a few trillion dollars, cheaper than reducing CO2 emissions.
