Release NMD process database v3.9
On 6 August, all licensees of the National Environmental Database received the new version, v3.9, of the NMD processes database. The NMD process database includes category 1 & 2 processes as well as generic basic processes (category 3) for use in LCAs by LCA preparers. Relevant processes in the NMD process database include material production and processing, waste treatment, transport and energy generation.
In preparation for the entry into force of the recently published change sheet of the Determination method, two variants of the process database have been delivered with this release: A process database based on ecoinvent 3.6 and a variant based on ecoinvent 3.9.1. In the amendment sheet, which will be effective from 1-1-2025, ecoinvent 3.9.1 is designated for ‘set 2’ for the preparation of new environmental declarations in the NMD, with a transition period of 6 months. For ‘set 1’ of new environmental statements in the NMD, ecoinvent 3.6 will continue to apply.
However, from the moment of delivery of this process database version, the NMD foundation will allow the calculation based on ecoinvent 3.9.1 when preparing new environmental statements for inclusion in the NMD for ‘set 2’. It is excluded that the ‘set 1’ results of new environmental statements may also be calculated with the process database based on ecoinvent 3.9.1. ‘Set 1’ may only be calculated based on ecoinvent 3.6.
