The United Nations has honoured President Mohamed Nasheed of the Maldives with its highest award for environmental leadership.
Nasheed was among six people to receive the 2010 Champions of the Earth award today at the Business 4 Environment conference in Seoul.
He has tried to attract international attention to threat of rising sea levels to his island nation, including holding an underwater cabinet meeting.
One of his boldest proposals is that his country go "carbon neutral," and he has urged others to follow suit.
The 46-year-old leader says he is delighted that "a small country can make a big impact on the world stage."
Past winners include former US Vice President Al Gore and former Soviet leader Mikhail Gorbachev.
