LONDON (Reuters) - European Union carbon prices nudged upwards early on Tuesday, in very quiet trade tracking prices of power, gas and oil, traders said.
EU Allowances for December delivery were up 6 cents or 0.4 percent at 14.47 euros ($18.54) a tonne at 0730 GMT, with light volume at 370 lots traded.
