Who we are
Fossil energy sources will become more scarce and therefore considerably more expensive in the foreseeable future. Furthermore, they contribute to global warming and climate change. For ground transport and shipping, alternative propulsion oiptions such as electric, solar or hydrogen can be developed in the near future. However, these are hardly suitable for use in aviation.
This is why the aviation industry is imposing efficiency and cost savings. In doing so, fuel consumption and CO2 emissions per passenger have been reducing continually for a number of years – with great success. While transport volumes have increased in the last ten years by around 50 per cent, jet fuel consumption has risen only three per cent. The long-term goal the international aviation industry has defined for itself extends well beyond this figure: By 2050, the CO2 output should have halved from its 2005 level.
However, this ambitious objective cannot be achieved through cost savings and efficiency alone, but only by using the widest possible range of alternative aviation fuels. These can be obtained from various feedstocks, e.g. energy crops such as jatropha, camelina or algae, which will not compete with food cultivation.
The objective of aireg - Aviation Initiative for Renewable Energy in Germany e.V. is to support the production and use of such alternative aviation fuels. aireg’s target is for biofuels to make up ten per cent of the jet fuel consumed domestically by 2025.
The biofuels initiative of the German aviation industry was founded in 2011 and combines the engagement and know-how of airlines, airports, research organisations and companies in the aviation and feedstock industries.
