programs / Aviation


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.

Lessons learned from Sweden’s electric vehicle rollercoaster
Although the Swedish government is planning to introduce a feebate program in 2018, which will likely bring an end to the EV market rollercoaster, other countries can learn a valuable lesson from the Swedish rebate program: dependable policies are key to steady EV market growth.

Why are EU manufacturers claiming their defeat devices are not defeat devices?
PSA has admitted to changing emission control calibrations under normal driving—but denies using banned engine software. The gaming of defeat device regulations has gone on for far too long in the EU. It's time for the charade to stop.

No, fuel economy standards do not put a million US jobs at risk
Ford CEO Mark Fields has to know that the US fuel-economy rules are already designed to “align with market reality.” Maybe he doesn't know that a study he's relying on for his numbers is discreditable.
