It's back to Poland for U.N. climate negotiators.

The coal- and natural gas-rich country is the only Eastern European nation bidding to host the 2013 U.N. Framework Convention Climate Change (UNFCCC) meeting.

Speaking in Doha, Qatar, where diplomats are currently negotiating toward a possible new treaty, Europe's lead climate negotiator, Artur Runge-Metzger, said it is "very likely" that Poland will be selected as host of the next Conference of Parties, or COP 19.

Coming on the heels of the meeting in Qatar, which boasts the world's highest greenhouse gas emissions per capita, the upcoming Poland gathering raised eyebrows and ire among observers in the Twittersphere.

Thomas Wyns, director of the Center for Clean Air Policy Europe, joked that the UNFCCC will soon mean the "United Nations Fossil Coal Collusion Convention."

And climate activist Meera Ghani wrote, "Shame that #Poland will most probably host #COP19, the EU's biggest blocker trying to greenwash COP."

The European Union has a target of reducing emissions 20 percent below 1990 levels by 2020, and Poland is strenuously trying to block attempts to increase that target to 30 percent.

Anja Kollmuss of Carbon Market Watch said in a statement that Poland also is blocking progress in Doha by refusing to agree to tightening the rules around pollution permits in the second phase of the Kyoto Protocol.

"The President of the climate talks needs to be able negotiate deals between parties and seal deals but the Polish government has shown it is not capable of this as it has repeatedly been against the wishes of the other 26 EU member states," she said.

Poland has hosted two U.N. climate conferences before, including the 2008 run-up to a major meeting the following year in Copenhagen, Denmark. The chance to host the climate meeting rotates among blocs of countries each year.

"They are in front of the entire league in hosts," Runge-Metzger said.

Meanwhile, France is bidding to host the conference in 2015, the year a new global agreement is expected to be signed. The Paris Protocol?
