Topics / Aircraft CO2 emissions

Starting January 1, 2012, European nations will implement an EC directive to incorporate international and domestic aviation emissions into the EU's Emissions Trading Scheme (ETS). The directive, which will impose a modest price on aviation growth (currently just over US$14.3/tonne CO2), is under legal challenge by US carriers and opposed by nations such as the US, Russia, India, and Brazil, and has sparked debate about what “equivalent measures” other countries can adopt that would exempt their carriers from the system. Simultaneously, the International Civil Aviation Organization (ICAO) is working to develop a global framework to control GHG emissions from aircraft for consideration at its 38th General Assembly in 2013. This includes a proposal for a global framework for market-based measures and a CO2 emission standard for new aircraft. The latter has been a major focus for the ICCT since 2009.

A sharp increase in revenue passenger miles drove both profits and fuel consumption on domestic operations up between 2014 and 2016 for U.S. airlines. Alaska Airlines again ranked first in overall fuel-efficiency, while the gap between it and the least fuel-efficient carrier, Virgin America in 2016, widened slightly to 26%.
