Platts moves annual roll for reflected vintages in Voluntary Carbon Credit Assessments to first working day of Q3

Platts, part of S&P Global Commodity Insights, has amended the annual roll for the vintages reflected in its Voluntary Carbon Credit assessments to the first working day of Q3 from the start of 2023.

A proposal published Oct. 21 is available here: https://www.spglobal.com/commodityinsights/en/our-methodology/subscriber-notes/102122-platts-proposes-to-move-the-annual-roll-for-reflected-vintages-to-first-working-day-of-q3.

The decision note published Nov. 30 is available here: https://www.spglobal.com/commodityinsights/en/our-methodology/subscriber-notes/113022-platts-to-move-annual-roll-for-reflected-vintages-in-voluntary-carbon-credit-assessments-to-first-working-day-of-q3

Previously, Platts methodology rolled on the first working day of the new year, with all assessments reflecting new vintages.

For example, under the previous methodology, the Platts Household Devices assessment reflected vintages from the last four years, including the current year, which would have been 2020-2023 on Jan. 3, 2023.

Under the methodology change, Platts will instead update the vintages reflected from July 3, 2023.

In the above example, Platts Household Devices will continue to reflect vintages from 2019 to 2022 on Jan. 3 and only roll to reflect vintages from 2020 to 2023 on July 3, 2023.

The methodology change has been made following research as well as market feedback, which found that credits reflecting current year vintage were not available for most product types until later in the calendar year, following the verification of individual project emissions data.

While credits for current year vintages for some project types are available promptly into the new year -- Renewable Energy and Methane Collection, for example -- current year vintage credits from other types of projects -- Agriculture, Forestry & Land Use (AFOLU) and Household Devices projects, for example -- typically take longer to verify.
