The renewability of wood briquettes is dubious at best, it's not clear the carbon emissions from biofuels is being properly accounted for, because many place don't consider the carbon release at time of burning, but rather at time of harvest. Unfortunately the rules of accounting for carbon emission at time of harvest aren't great either, with it being possible to simple not account for the carbon emission by claiming a clear-cut forest is still a forest, so no land use change has occurred, and thus no need to account for carbon emissions resulting from land use change (which is the trigger point for computing the carbon emission of cut trees).

In addition burning biofuels like wood briquettes and wood pellets at home release horrific amounts of carbon monoxide and other small particulate from incomplete combustion. Stuff that does horrific things to local air quality, we'll see the return of impenetrable smog to our cities, and health warnings telling asthmatics not to go outside for risk of dying due to inhaling all the nasties.
