The campaigners greeted guests attending the Solaris workshop at Sydney's Novotel with warnings that APP was encroaching on the habitats of endangered orangutans and Sumatran tigers.

Greenpeace said the APP customers at the offices, who were on site for a certification workshop, had been receptive to their information.

After speaking with a number of APP's customers, the protestors were kindly asked to move on by "bemused" security guards, according to Greenpeace.

Reece Turner, Greenpeace forests campaigner, said: "APP, and its affiliate in Australia, Solaris, are not just forest destroyers, they’re also brand destroyers.

"With a track record of dirty tactics and greenwash and a long list of abandoned contracts, Australian companies would be wise to buy their pulp and paper products elsewhere."

The stunt was part of an ongoing campaign by Greenpeace. Last November, the NGO hijacked an awards ceremony in Europe to present "The Golden Chainsaw Award" to the paper manufacturer.

APP's attempts to promote its environmental progress have been met friction from Greenpeace. The paper company's plan to relocate six Sumatran tigers was branded as 'greenwashing' by the NGO.

APP has been driving a campaign to show it is improving its environmental credentials. It recently announced a partnership with Carbon Conservation to draw up a set of goals to guide its sustainability practices over the next decade.

The paper company has said it is committed to sourcing 100% of its pulpwood supply from sustainable plantation stock by the end of 2015 and to have all its exclusive pulp suppliers achieve Indonesian environmental standard LEI by 2020.
