If foresters get a big carbon credit, or dairy farmers get an emissions "holiday", it amounts to taxpayer handouts for those sectors. That might be defensible on pure carbon reduction grounds, but there are considerable issues of fairness etc... Both together, definitely – if only because public policy needs to be even-handed.

You're in the ballpark, but on the high side. If you need anything more specific, I can ask a forester who knows more... You can supply your own numbers for area ;-) My understanding is that a 15 year old radiata stand is reckoned to contain 112t C, so the average C absorption would be about 7500kg/ha/yr.

If 10% of NZ was planted in trees and those trees absorbed 10,000 Kg/Ha/yr carbon, that would be 25 million tonnes carbon or 92 millions tonnes CO2/yr.
