The CITES working group meeting that just concluded in Tel Aviv, Israel a few days ago decided it would not recommend a vote to move polar bears from Appendix II, where they are now, to Appendix I, at the next general CITES meeting in 2016.
It appears, however, that the US – which was behind failed petitions in the past (in 2010 and 2013) and voiced an official objection to this 2015 decision – is threatening to raise the issue again at the next all-nations meeting of CITES in September 2016 (probably with a petition at that meeting).
The USA is trying to bully Canada and the international community to adopt its own shaky interpretation of what constitutes good polar bear science and it looks like it may refuse to give up until it has won.
UPDATE: 7 September 2015, CITES press release (pdf here, relevant passage marked by me):
“The Committee’s Review of Significant Trade concluded that the current level of trade in polar bears, amongst others, is not detrimental to the survival of the species in the wild.”
