Prepare your ETS annual emissions return, with confidence

CarbonBlock helps small forestry block owners registered in the Emissions Trading Scheme calculate carbon stock changes, keep an activity record, and get their figures ready ahead of the 31 March deadline — sitting in front of MPI's Tupu-ake/NZETR filing system, not replacing it.

Carbon stock calculations

Estimate carbon stock and year-over-year change against MPI's published Standard Carbon Tables for your block's category, planting date, and area.

Activity record-keeping

Log planting, harvest, thinning, and land-use changes that affect future calculations, all in one place per block.

Multi-block dashboard

See every block you own and which ones are return-ready ahead of the annual deadline.

What CarbonBlock isn't: it is not tax or legal advice and does not file your return for you — it prepares figures to reference or hand to your accountant/forestry consultant while you file on MPI's Tupu-ake/NZETR system.
