A new Greenpeace report says illegal and destructive logging in Papua New Guinea is diminishing the carbon value of the country's forests and is the major source of its greenhouse gas emissions.
The report examines how much carbon is released by selective logging in PNG.
A Greenpeace forest campaigner Grant Rosoman says selective logging is often thought to have a low impact on the amount of carbon stored in forests because, although degraded, the forests still exist.
However, the report shows that selective logging also releases a huge amount of carbon.
While the money from decades of forestry in PNG has not filtered back to forest communities, rampant deforestation continues to damage the climate.
Mr Rosoman says PNG could earn billions of dollars from carbon funding, but ongoing destructive logging and poor forestry governance mean the country still has a long way to go to convince the world it can protect its forests and distribute funds equitably to local communities.
