I'd say that we need to discover a source of energy that produces SO2 as a byproduct, but given our species' track record we would probably trigger an ice-age in a few decades.

Hah!

Or maybe if some billionaire could figure out a way for their space-tourism project to “accidentally” produce SO2, then we’d give them the moral mulligan.

SO₂ was a byproduct of coal power stations, we started scrubbing it because it was the cause of acid rain.
