Tokyo - Britain's Prince Charles on Tuesday called for concerted efforts to build a low-carbon society to combat global warming while on a visit to Japan.
"We must not abandon the drive towards a low-carbon economy," the prince of Wales said in a speech marking the 150th anniversary of bilateral relations between Japan and Britain.
He arrived in Tokyo late Monday with his wife, Camilla, for a five-day visit.
The prince called climate change "the biggest challenge our planet has ever seen."
He said that even as the world now faces a financial crisis, it should not divert attention and efforts from protecting the earth.
