Aircraft play a vital role in our modern economy by quickly and conveniently transporting goods and people. But they also exact environmental costs. If counted as a country, globally the aviation sector would rank 7th in terms of carbon dioxide (CO2) emissions, just after Germany and well above Korea in 2011. Projections are that CO2 emissions from aviation will triple by 2050 under business-as-usual scenarios, as more people and goods move by air, unless effective policies are developed to constrain emissions growth. Nitrogen oxide (NOx), particulate matter (PM), noise, and lead pollution also impact often disadvantaged communities living near airports.

A number of governments and international organizations are working to manage the environmental impact of the aviation industry. The International Civil Aviation Organization (ICAO), a specialized UN agency, oversees and acts as the de facto regulator of airlines and aerospace manufacturers worldwide. ICAO adopted its first aircraft noise standard in 1972 and its first engine certification standards for air pollutants in 1981. Since then, ICAO has periodically tightened both policies, and is currently developing the world’s first CO2 and PM emission standards for new aircraft and engines, respectively.

The world turns to electric vehicles
Progression to a robust electric vehicle market is happening, and the world is turning, but the question that remains is how fast? And the answer largely depends on if everyone – governments, automakers and consumers – all align.

Opel's admissions of defeat device calibrations
Opel admits to reducing vehicle emission controls based on conditions other than ambient temperature or restart. Opel says its “engines are in compliance” in Europe. But, once again, they would not be legal in the US, and the difference is instructive.
