Carbon offsets store the CO2 in plant matter that will eventually decay if not maintained. Carbon capture pumps it into the ground, where it is stored permanently - so it’s a matter of your timeframe. Personally, I prefer carbon offsets as carbon capture is likely to get much more efficient over the next 100 years (lifetime of a tree), so it’s better to pay for it later.
