What a great idea ! Sadly, we don't know how.
CO₂ is produced by the process of burning almost everything we burn for energy ... like coal, natural gas, oil, paper, wood, gasoline, alcohol, candle-wax, airplane fuel, whale oil, olive oil, Diesel fuel . . . stuff like that.
We certainly could stop producing CO₂ if we're willing to stop driving most cars, buses, taxis, trains, and airplanes, stop generating most of the electricity we use, stop heating most homes and other buildings, stop doing most of the cooking that we do, stop making most of the hot water we make, stop using most of the electric light, lanterns and candles that we use, and generally stop burning all of that stuff.
OR . . .
Find a way to burn it without producing CO₂ .
OR . . .
Find other ways to produce the energy we want WITHOUT burning that stuff.
THAT's why you're hearing so much these days about solar energy, wind energy, and nuclear energy. Those don't produce ANY CO₂ .
(I didn't put bio-Diesel and Ethanol on the list. These are just methods to avoid making fuel from oil pumped out of the ground, but they produce just as much CO₂ when they burn. So they're solutions to the problems and costs of oil production, but they're no help at all with the CO₂ problem.)
