Recent reports that trees may not be the solution to carbon offsetting appeared a few days ago in Grist (Their bark is worst for our blight) and in Live Science (Trees may not fix global warming) may prompt a rethink of the carbon offsetting appraoch to addressing carbon reduction. This is based on 10 year research by scientists at Duke University,  North Carolina

So those projects and facilities looking to achieve carbon neutral or zero tragets through off setting need to be very confident the route they are taking is sound.

Although critical of carbon off putting, this report in WorldChanging, Rural Biogas, Global Carbon Market of a grass roots initiative gives inspiration, along the lines of a contraction and conevrgence approach which looks to be a more appropriate alternative to carbon off-putting
