Bespoke joinery company James Johnson & Co Ltd received its Programme for the Endorsement of Forest Certification (PEFC) schemes chain of custody certificate at a ceremony to celebrate the £24m refurbishment of the Defra Nobel House headquarters in London.

Permanent secretary of state Helen Gosh presented the certificate on behalf of secretary of state for environment, food and rural affairs, Margaret Beckett, to James Johnson partner, Bill Frost.

London-based James Johnson was part of a fit-out team that used only independently-certified wood products on the Nobel House contract.

PEFC UK chairman Mike Clark said: “With over half of the world’s certified forests globally now sustainably managed through PEFC-endorsed certification systems, delivering hundreds of millions of tonnes of certified timber, the PEFC scheme has greatly increased availability of certified timber to companies such as James Johnson which is committed to the responsible sourcing of raw materials.”
