Iogen and General Motors "Green" UN Climate Change Conference in Montreal

MONTREAL, Nov. 25,2005 - Twelve Canadian-built ethanol flex fuel Chevrolet Impalas, fueled with Iogen's cellulose ethanol, will shuttle conference delegates of the U.N. 11th Conference of Parties Framework Convention on Climate Change held in Montreal from November 28th to December 9th.

The flex fuel Chevrolet Impala is capable of running on fuels blended with up to 85% ethanol. Michael Grimaldi, President of GM, stated, "We are proud to provide the Climate Change Conference participants from around the globe with Canadian built cars powered by Canadian made cellulose ethanol. With this fuel, the Chevrolet Impala has a net CO2 footprint that is less than any vehicle sold by any automaker in North America."

The joint effort between the Government of Canada, General Motors and Iogen is a prime opportunity to showcase recent innovations in advanced vehicle technology, alternative fuel technology and Canada's commitment to its Kyoto Climate Change Plan.
The Hon. John McCallum, Minister of Natural Resources stated, "I am pleased to see GM's auto industry leadership, in showcasing a full size sedan with this ultra low CO2 emissions capability at the COP 11 conference."

"This demonstrates the extraordinary environmental potential of combining advanced vehicle and fuel technologies to reduce greenhouse gas emissions," said the Honourable David L. Emerson, Minister of Industry. "This is a great example of how Canadian business has risen to the challenge of reducing emissions through innovation and environmentally sound technology and the Government of Canada is proud to partner with them on such initiatives."

Canadian-based Iogen Corporation is providing 4,000 litres of its fuel to be used in the vehicles during the Conference. Cellulose ethanol is made from agricultural residues such as cereal straws and corn stover. "Iogen is pleased to demonstrate firsthand to UN delegates that cellulose ethanol is ready to go," says Jeff Passmore, Executive Vice President, Iogen Corporation. "By using straw to make this low CO2 fuel, we are reducing gasoline consumption and GHG emissions without altering our mobility or ability to travel," says Passmore.

GM has been working with the government of Ontario and the Federal government and the fuel industry in the promotion of this vehicle technology in an effort to improve the availability of ethanol based fuels in Canada. GM is the largest producer of ethanol powered flexible fuel vehicles (capable of running on gasoline blends containing up to 85% Ethanol (E-85)) with over 1.1 million vehicles on the road in North America.
