context_page_description: Aviation affects the environment due to aircraft engines emitting noise, particulates, and gases which contribute to climate change and global dimming. Despite more fuel-efficient turbofan and turboprop engines, the rapid growth of air travel in recent years contributes to an increase in total pollution attributable to aviation. In the EU, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.
  At present aviation accounts for 2.5% of global CO₂ emissions. Due to projected growth in air travel, in the most technologically radical scenarios for having a better than 50% chance of keeping global warming below 2 degrees Celsius, in 2050 aviation will make up 15% of global CO₂ emissions. In more conventional scenarios its emissions will exceed the entire global carbon budget before then. This presents governments and the operators of aircraft with a responsibility to reduce the aviation industry's emissions.
