On an international level, the EU commission, the UN Aviation Authority - the ICAO – and associations from the aviation industry are ambitiously pursuing climate protection objectives. Despite the forecast of growth in aviation, the aim is to reduce the climate impact of our sector. Various goals for reducing aviation emissions have been defined in recent years.
The member airlines of the International Air Transport Association (IATA) have set ambitious reduction targets for their industry. The aim is to increase CO2 efficiency for fuels by 1.5 per cent annually. From 2020, global aviation should then guarantee CO2-neutral growth; by 2050 net CO2 emissions should be reduced by 50 per cent compared to the base year 2005.
EU 2011 Transport White Paper
According to the EU Transport White Paper from 2011, this transport sector should reduce greenhouse gas emissions by at least 60 per cent (compared to the 1990 level) by 2050. Furthermore, the EU Commission is calling for the aviation industry to use up to 40 per cent sustainably produced and low CO2 fuels by 2050.
European Advanced Biofuels Flight Path
Airlines, aircraft manufacturers and producers of alternative aviation fuels, together with the EU commission, have launched a biofuels initiative – the European Advanced Biofuels Flight Path. The objective is to achieve an annual production of two million tonnes of aviation biofuel by 2020.
The research and innovation strategy Flightpath 2050 developed by the European Commission in collaboration with the aviation and aerospace industry aims to strengthen the competitiveness of the European aviation industry with ambitious emissions reduction targets. The initiative calls for CO2 emissions to be lowered by 75 per cent and nitrogen oxide emissions by 90 per cent by 2050. Both of these values refer to aircraft with a level of technology corresponding to the base year 2000.
The Advisory Council for Aeronautic Research in Europe (ACARE), the European Commission’s aviation research advisory committee, intend to reduce CO2 emissions per passenger kilometre of aircraft with a level of technology corresponding to 2020 by 50 per cent.
