An international group of environmental organizations Wednesday gave Japan a second "Fossil of the Day" award during an ongoing climate conference for its lack of pledges to fight global warming.

The Climate Action Network said it gave Japan the Second Place Fossil award for Environment Minister Hiroyuki Nagahama's failure to mention in his speech at a U.N. climate meeting the country's pledge to reduce emissions by 25 percent by 2020 compared to 1990 levels and for failing to give specifics about Japan's future financial aid to developing countries.

Japan has "seriously undermined the momentum of the negotiation," the group said, referring to the 18th United Nations Conference of the Parties to the U.N. Framework Convention on Climate Change that opened in Doha on Nov. 27.

The group awarded Japan the dishonorable First Place Fossil Award on the opening day of the conference, known as COP18, for lack of efforts against global warming.
