On Tuesday, the earliest full day of negotiations in Katowice, capital of mining region Silesia, President Andrzej Duda told workers celebrating the feast within their patron Saint Barbara the fact that industry has a long future.

The comments sent shock-waves through two-week U.N. talks Poland is hosting to agree rules for working with the 2019 Paris accord to phase out fossil fuel.

"Poland is not building more new coal structures. It's quite a powerful engagement," he said inside the interview. "New additional capacities have been constructed in the renewables sector."

Poland, which relies on coal for approximately Eighty percent of the power and most 82,000 mining jobs, can be an unlikely host for U.N. climate talks, but Kurtyka said the region was eager to share with the remainder world its ability of transition.

Campaigners are highly critical within the pace of change as evidence mounts in the growing gap involving the need to cut emissions as well as the work succeeded in doing so far.

This week's U.N. talks are technical negotiations before ministerial debate a few weeks.

Kurtyka said challenges included sharing the duty between developed and third world countries with the tariff of moving to your low-carbon world. But political will was strong to provide about the 2019 Paris agreement and climate concern could override national agendas, during politically divided times, he added.
