2 years 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: Using tonne year accounting in this manner is greenwashing. It is the climate equivalent of Eron's "mark to market" accounting. If carbon is only held out of the atmosphere for a year, you have done nothing. Permeance needs to be real and long lasting. You cannot apply a simple discount rate to the climate as it fails to take into account the drastic effects of the climate crisis, negative feedback loops inherent in climate change, and the human cost of climate change
Proposed Change: Tonne year accounting is unacceptable, and SHOULD NOT be used
