ABIDJAN, Ivory Coast (AP) — New documents on logging permits in Ghana indicate most timber exported from the country is likely illegal, exposing purchasers to possible jail time under a new European Union regulation, the environmental watchdog group Global Witness said Tuesday.

In February, Ghana’s Forestry Commission gave Global Witness lists of permits covering more than 15,000 square kilometers (5,800 square miles), or nearly 15 percent of the country’s land mass, the group said in a new report. Permits for more than 12,000 square kilometers (4,600 square miles) were not covered by the country’s 1998 Timber Resources Management Act, calling their legality into question.
