GLASGOW, Scotland — The British government says pledges of new or earlier deadlines for ending coal use have come from more than 20 countries including Ukraine, Vietnam, South Korea, Indonesia and Chile. Meanwhile, Poland, the second-biggest user of coal in Europe after Germany, appeared to backtrack on any ambitious new commitments within hours of the announcement at the ongoing U.N. climate conference. “Energy security and the assurances of jobs is a priority for us,” Anna Moskwa, Poland’s minister for climate and environment, said in a tweet, citing the government’s existing plan which “provides for a departure from hard coal by 2049.” Transformacja w najbliższych latach musi być przede wszystkim zaplanowana i sprawiedliwa. Przyjęta przez Rząd RP umowa społeczna zakłada odejście od węgla kamiennego do 2049 r. Bezpieczeństwo energetyczne, jak i zapewnienie miejsc pracy jest dla nas priorytetem. #COP26 — Anna Moskwa (@moskwa_anna) November 4, 2021 Earlier in the day, it had seemed that Poland might bring that deadline forward by at least a decade. Campaigners reacted angrily to the apparent U-turn. “Moskwa has underscored that her government cannot be trusted to sign a postcard, let alone a responsible climate pledge,” said Kathrin Gutmann, campaign director of the group Europe Beyond Coal.
