METALS-Aluminium rises on supply worries as China pledge's emission curbs

(Updates prices)

HANOI, May 4 (Reuters) - London aluminium prices rose on Tuesday over concerns that a commitment to reduce pollution by top producer China could limit the energy-intensive metal’s supply.

Three-month copper on the London Metal Exchange rose 1.5% to $2,433.50 a tonne by 0647 GMT, copper advanced 0.8% to $9,900 a tonne, zinc was up 0.5% at $2,941 a tonne, while nickel increased 0.7% to $17,795 a tonne.

“We expect aluminium to remain supported in the short term amid concerns climate change policies in China will curb output,” said ANZ analysts in a note.

“Coal-fired power is used by more than 80% of China’s aluminium smelters. Pollution-reduction policies are likely to push many of them to hook up to the grid, thereby increasing their costs,” they added.
