The Bank of Japan will consider climate change in its monetary policy discussions, Gov. Haruhiko Kuroda has said in his clearest signal yet that the central bank is looking to support the battle against global warming.

"We have a great interest” in climate change and its impact on the economy and the financial system, Kuroda said in an interview Thursday. "Naturally, how we respond to this at the level of monetary policy will become a topic of discussion.”

The comments come amid growing debate among central bankers over whether or how they should support efforts to counter climate change, following a series of pledges by governments including the United States, China and Japan to reduce greenhouse emissions.
