news about cheap fares and airlines from travel search engine Trabber

Lufthansa is set to become one of the world’s first airlines to mix biofuel with traditional kerosene on commercial flights as carriers seek ways to cut soaring fuel costs.

The German flag carrier will start running its engines on some flights on a mix of biofuel and kerosene within two years. Aircraft account for an estimated 2-4 percent of global carbon dioxide (CO2) emissions, which scientists say could cause global temperatures to rise, triggering widespread disease, famine, flooding and drought.

Experts say global aviation emissions could reach 2.4 billion tonnes in 2050, which would be 15-20 percent of all CO2 permitted under a global agreement and a nearly four-fold increase on current levels.
