The “Illegal logging: Cut it Out” report estimates that 3.2 million m3 of illegal wood is imported into Britain annually, with most products being used in the construction industry. The study says much of the wood originates from Russia.

However, one of the report’s authors told TTJ that the the calculation methodology used was “crude”. “Trying to measure illegal trade is nigh on impossible, so this is only an estimate.” He added that they had tried to err on the side of caution in their estimates.

The study, which draws from previous research, focuses on 17 exporting countries and assumes that 10% of each country’s timber exports are illegal and that 10% of the UK’s timber imports from those countries are illegal.

Sweden, Finland and Latvia are mentioned as big illegal wood exporters to the UK, due to their use of Russian logs.

Illegal UK sawn softwood imports are estimated at 1.7 million m3 roundwood equivalent, with hardwood at 170,000m3, plywood (220,000m3) and chipboard (15,000m3).

No wood which is certified to any recognised scheme is included in the figures.

As well as calling for new EU-wide legislation on illegal timber imports, WWF wants the government to introduce measures to monitor how much legal and sustainable timber and wood products it sources and set clear targets and deadline to increase this.
