That's all the CO2 lifecycle is in nature - Oil / Gas are basically large sponges which absorbed Carbon a long time ago, and were buried.
It's not impossible that we could grow a huge number of trees, and bury the resulting wood in a mountain-side to offset burning coal - but the amount of wood we'd need to bury might be prohibitively large.

(We've buried much worse things than wood :) ).
