Despite a sign of global economic recession, the private sector can help solve environmental issues by creating new business and stimulating the economy, according to Noel Brown, former director of the North American regional office of the United Nations Environmental Program.

Companies around the globe are urged to meet the demand of consumers who are increasingly becoming keen of environmental issues, he said Friday.

"We believe that economic sustainability and profitability are possible, if you initially invest to create environmentally sound products," Brown said in an interview with The Japan Times in Tokyo.
