Metsä Group’s Kuura textile fibre shows competitive greenhouse gas emission level

Metsä Group has completed a new Life Cycle Assessment (LCA) of its Kuura textile fibre. The assessment shows that Kuura’s global warming potential (GWP100, fossil) score is less than one-third of the next best option, viscose.

The Kuura project is currently in a demonstration phase. The new textile fibre is being developed by Metsä Group’s innovation company Metsä Spring. The LCA was made by Etteplan. The LCA study and comparison to alternative cellulosic fibres were critically reviewed by RISE Research Institutes of Sweden.

GWP is a term used to describe the relative potency, molecule for molecule, of a greenhouse gas, considering how long it remains active in the atmosphere. Kuura’s GWP is only one-fourth of cotton fibre and up to over 80 percent lower than the impact of the closest reference commercial product, lyocell fibre.

Public Consultation: Small changes process to amend four International Generic Indicators (IGI)

The ‘small changes’ process mandated by the FSC Board of Directors at their 86th Meeting aims to improve aspects of gender inclusiveness and the glossary of terms by revising four International Generic Indicators (IGI) in the FSC-STD-60-004 V2-0 EN. For this purpose, an internal technical working group (I-TWG) was appointed in FSC’s Performance and Standards Unit (PSU) in October 2021 to propose draft revised IGI (1.6.4, 4.6.4, 2.2.3 and 2.2.5) and to define a new glossary term. ‘Small changes’ are defined as the revision or addition of one or two requirements. PSU is following Clause 2.2 in Annex 4 of FSC-PRO-01-001 Development and Revision of FSC Normative Documents to conduct this process. FSC is now inviting you to support the process by submitting your feedback through 11 May 2022. The public consultation can be accessed here.
