1 year ago NCX response: We appreciate comments noting that the structure and performance of the baseline model used within this methodology is strongly influential on the predicted and realized climate impact of projects. Our revised methodology increases transparency rather than following an expert review process. This includes both detailed documentation of particular models used, as well as sharing benchmarking and performance information for baseline models. Finally, the revised approach to uncertainty explicitly accounts for imprecision in the baseline model in calculating the final number of credits generated from projects developed under this methodology.

2021 Deferred Harvest Methodology Section: Model for carbon-at-risk of removal (section 11)
Comment: The methodology employs a model to determine baseline emissions to predict the carbonat-risk of removal. However, the model uncertainty has not been assessed. The requirement is: All plausible sources of model uncertainty, such as structural uncertainty or parameter uncertainty, shall be assessed using recognized statistical approaches such as those described in 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Volume 1, Chapter 3.
Proposed Change: VCS Rerefence: VCS Methodology Requirements Section 2.5.1
