Pew Report Finds Reductions in Aviation GHG Emissions over Business-as-Usual Projections Could Be Halved
(GreenAirOnline.com) Under business-as-usual (BAU) forecasts, CO2 emissions from global aviation are estimated to grow 3.1% per year over the next 40 years, resulting in a 300% increase in emissions by 2050 compared to 2007. However, a new report published by the Pew Center on Global Climate Change finds that reductions of more than 50% below the projected levels are possible. The report, which looks at both the aviation and marine transportation sectors, presents a range of near, medium and long term mitigation options. For the near to medium term (to 2025), improvements in operational efficiency – for example advanced navigation and air traffic management systems for aviation – have the potential to reduce GHG emissions by about 5% below BAU projections, with advanced propulsion systems and new airframe designs further reducing emissions by up to 35% over the longer term (to 2050).
