Case study 1:
Assessment of Category B evidence: Greenheart timber from Guyana
The Environment Agency undertook a full assessment of Category B evidence for a supplier of tropical hardwood timber that cannot be purchased as FSC / PEFC / MTCC / SFI / CSA certified timber. This example applies to purchases of Greenheart timber which the Agency uses in marine and freshwater construction applications, e.g. beach groynes.
One of the Agency’s main suppliers of Greenheart timber is Aitken & Howard Ltd (A&H Ltd). The Agency has been working with A&H Ltd since 2004 to verify the legality and chain of custody of Greenheart from Guyana. However, with the introduction of CPET’s “Framework for evaluating Category B evidence” in 2006, a more comprehensive programme of work has been implemented.
