“Campaigners against climate change today denied claims they were planning to disrupt Heathrow with hoax bomb threats or runway protests as part of their week-long protest against air travel.”

Climate campaigners are camped outside London’s Heathrow airport to rally against expansion plans for the airport. They have threatened “direct action” but state that they will not endanger passengers.

IATA, the global airline body representing 240 airlines announced its plan to convert to electronic tickets by June 1, 2008. This change will not only cut airlines’ costs ($9 per traveler) but also save 50,000 mature trees a year.

A proposal to include airlines in the European Union’s emissions trading scheme is delayed to 2012.

“The European Union will press ahead with plans to include aviation in its emissions trading system despite United States’ efforts through a UN body to discourage it, a spokeswoman for the EU executive said on Friday.”

Several U.S. states and environmental groups are expected to ask the U.S. Environmental Protection Agency to “crack down on airline emissions.” Aviation emissions account for up to 12% of the U.S. transportation sector, according to the Chronicle’s citing of EPA numbers.

Environment ministers in the European Union have agreed to include airlines in their emissions trading scheme starting from 2012.
