1 year ago NCX response: A tonne-year is simply a unit of carbon account like a kilowatt hour is to a kilowatt for electricity, a unit of volume over time. While tonne-year accounting may not be used widely today in the voluntary carbon market, it has been supported as an alternative to traditional carbon accounting in the scientific literature for many years. One cannot adequately know the full benefit of a solution without adding in the time or duration term. Fundamentally, tonne-year accounting allows for the delivery of realized impact, not presumed future impact on timescales incongruent with the variability of natural systems. Furthermore, tonne-year accounting allows the direct comparison of benefits of different carbon offsets approaches over many different time scales and technologies.

Comment: • Tonne-year methodology: The NCX proposal rests on “tonne-year” methodology that remains highly contested. I continue to oppose the assumptions that underlie the method because of the disconnect between the mathematical, theoretical construct of the approach versus the realities of actual, in field, forest growth, the natural variability of biological systems, harvest scheduling, carbon storage, the physics of carbon in the atmosphere and other real-world factors that are ignored by the method.
