Antalis-owner Sequana Group and office supplies chain Staples have already stopped supplying products manufactured by APRIL, which is the subject of the latest Greenpeace report into deforestation in Indonesia.
The report followed a Greenpeace flyover that photographed ongoing clearance of dense forest and the drainage of peatlands at the site of an APRIL supplier on Padang island off the coast of Riau in May.
The NGO said this was evidence that APRIL's claim that it does not develop land that is of "high conservation value" – based on assessments that have been independently peer reviewed by the High Conservation Value Resource Network (HCVRN) – were false.
Greenpeace added that it had confirmed with HCVRN that the network had carried out peer review assessments for just two out of an estimated 50 concessions that are believed to supply APRIL.
In addition, Greenpeace claimed that APRIL had publicised support for its 'Sustainable Forest Management Policy' from the WWF and Norwegian government, both of which denied having endorsed the policy when contacted by the NGO.
Greenpeace Southeast Asia forest campaigner Zulfahmi said: "APRIL has been caught telling its customers it has support from governments and NGOs at the exact same time its bulldozers are out trashing Indonesia's rainforests and peatlands.
"Apparently APRIL doesn't consider the clearance of rainforest on areas of deep peat to be in conflict with its conservation commitments. But Indonesia's forests are disappearing faster than anywhere else in the world precisely because of practices such as these."
Antalis regional purchasing director UK & Ireland Andy Christian confirmed that the paper merchant had never stocked APRIL products in the UK, while Sequana has issued a statement clarifying its position on responsible sourcing.
The statement concludes: "The Sequana Group is particularly concerned by deforestation and degradation of natural forests, especially in South East Asia and encourages all actors of the supply chain to stop any kind of forest degradation or natural forest clearance.
"To this end, the Group decided, in December 2012 to stop commercial relationships with companies accused by majors international NGOs of deforestation in Indonesia. Furthermore, the group has today no commercial relationship with such companies and will not have in the future unless those companies make strong commitments and take actions toward natural forest conservation."
APRIL had not responded to requests for comment at the time of writing.
