2021 Deferred Harvest Methodology Section: Tonne-year accounting

Comment: We would like confirmation that the proposed tonne-year conversion rate is 100 years. This is not clear in the methodology. We also recommend explicitly clarifying that application of discount rates is not permissible.

Proposed Change: No Proposed Change

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.
