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: Feedback on 1 Year Projects Utilizing Tonne Year Accounting
Proposed Change: Although still subject to final approval in the VCS Standard 4.2 updates (which we are still awaiting responses to the public comments) the addition of tonne-year accounting (TYA) should only be considered if implemented appropriately and without loopholes to ensure that the emissions reductions are real, additional, and verifiable.
