Biochar is a potential solution, although the technology isn't there yet (at an industrial scale).

If wood is heated in an oxygen free environment it will turn into a form of charcoal. At the same time it will release gases (like methane) that can be captured and used as a fuel separately.

Rather than burning the charcoal, it is put back into the soil which effectively traps the CO2. This also improves the condition of the soil and reduces the need for fertilisers.
