Russia, Belarus and Ukraine then further delayed the endgame of the conference with an argument over so-called "hot air" - the pollutionpermits they were given to allow their heavy industries to thrive.
Those industries collapsed but Poland and Russia insist that - as they suffered economic pain during the collapse - they should be allowed to use up the pollutionpermits as their economies grow again.
It has withheld permits for coal mines, tightened pollution controls for power plants that use coal, and is in the process of drafting regulations on greenhouse gases.
Several data centers, including several operated by Amazon in northern Virginia, have faced large fines because their emergency generators were installed without permits, and others because the diesel generators have contributed significant air pollution during testing.
Now, as the pollution battle shifts from sulfur to carbon, the enviros declare that it isn't right to give only polluters permits to emit naughty gases.
