Bahrain's national carrier Gulf Air has joined an industry consortium which aims to develop bio-fuel for aircraft by 2013, reported Gulf Daily News. The airline is partnering with eight other carriers, including Air France and KLM, along with Boeing and refining technology developer, Honeywell UOP, to fund research which will produce environmentally-friendly economic fuel. The consortium's charter is to enable the commercial use of renewable fuel sources that can reduce greenhouse gas emissions, while lessening commercial aviation's exposure to oil price volatility and dependence on fossil fuels. Gulf Air is the only Middle East airline taking part in the project.
