The emission reduction goals of the international aviation sector are ambitious: From 2020, global aviation is aiming to achieve CO2-neutral growth and by 2050, net CO2 emissions shall be reduced by 50 per cent compared to the base year of 2005. Alongside technological developments and efficiency gains, this should also involve an increase in the use of renewable fuels.
Sustainability must have first priority in the production and use of alternative fuels. It is imperative to prevent a rise in food prices, competition for water and negative changes in land use in the course of the producing the biofuels.
Under these conditions, feedstock production for biofuels offers several clear advantages: The creation of a new agricultural sector in developing countries can serve as a catalyst for further development in these respective regions. Sustainable agricultural practices create jobs, promote the expansion of local infrastructure and counteract rural depopulation.
Today, there are already different national and international sustainability guidelines concerning the production of biofuels. These initiatives and regulations must be harmonised or, at the very least, acknowledge one another, in order to achieve worldwide sustainability standards in biofuels for aviation.
