I honestly think we have bigger problems right now, like spending money on ways to reduce greenhouse gasses. We need to develop alternatives to non-renewables and, until we can use the alternatives, work on removing the gasses from the atmosphere.
Putting my money where my mouth is: I've been looking into this and as soon as I get my credit card (to be able to pay, I've never needed a CC before), I will sign up with https://climeworks.com to recapture some of my CO2. They seem to be one of the few that are actually capturing right now, so the money will be used for real capture, not just R&D that might yield results in the future. But to spread the risk, I am also going to spend money on the more traditional method of planting trees (which company is TBD, I have yet to find one that actually guarantees that they (or the locals) won't rip the tree out before it had a chance to capture its promised CO2). On the reduction side, I travel to work by public transport, work from home (it stays naturally cool) instead of using our office air conditioning unit, have a 100% renewable energy contract at home, etc.
