BRUSSELS, Oct 16 (Reuters) - European Union leaders agreed on Thursday to use unanimity rather than majority voting to take the final decision on adopting ambitious climate change measures, Polish Prime Minister Donald Tusk said. The legislation to curb greenhouse gas emissions and promote renewable energy sources would normally be adopted by qualified majority voting under EU procedure when member states and the European Parliament are co-legislators. Poland had threatened to veto a December deadline for the package unless more was done to shield Warsaw's coal-based economy from the impact of the emissions curbs. Tusk told a news conference after an EU summit: "We managed, with the help of 8 countries, to convince the others that we will take a final decision on the package in December by unanimity."
