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.

2021 Deferred Harvest Methodology Section: No Section Indicated
Comment: Section 2 of the methodology indicates a tonne year accounting conversion rate has been separately approved by Verra. This is not quite true – there is still an open public consultation for the VCS Standard v4.2 update. Later on, in Section 9, the description of the TYC parameter acknowledges that the tonne year accounting conversion factor is still proposed and open for public comment. The TYC parameter is critical to the quantification approach contained in this methodology. Since this factor is still subject to change during the public consultation of the VCS Standard v4.2, we suggest that it is challenging to fairly evaluate this methodology without having that information finalized.
Proposed Change: We request that Verra provide a second opportunity to comment on this methodology if the TYC parameter approved in the final version of the VCS Standard v4.2 changes.
