Aviation Policies

The European Union's policy on Aviation Emissions

From the start of 2012, the European Union (EU) required its members to include emissions from flights arriving at and departing from their airports in the EU scheme of emissions allowances and trading, while encouraging other nations to take equivalent measures. The EU exempts biofuel and claims to take a 'comprehensive approach' to reducing environmental impacts of aviation. To create space for political negotiations to get an international agreement regulating emissions from aviation, the EU has meanwhile postponed implementation of its directive by one year.

What kind of international agreement could be reached on aviation emissions? What policies work best? How do aviation policies fit into a comprehensive approach?

A Comprehensive Plan of Action on Climate Change

A comprehensive plan is best endorsed globally, e.g. through an international agreement building on the Kyoto Protocol and the Montreal Accord. At the same time, the specific policies are best decided and implemented locally, e.g. by insisting that each nation reduces specific emissions by a set annual percentage, and additionally removes a set annual amount of carbon dioxide from the atmosphere and the oceans, followed by sequestration, proportionally to its current emissions.

Policy goals are most effectively achieved when policies are implemented locally and independently, with separate policies each addressing the specific shifts that are each needed to reach agreed targets. Each nation can work out what policies best fit their circumstances, as long as they each independently achieve agreed targets. Counting emissions where they occur will encourage nations to adopt effective policies, such as imposing fees on the sales of products in proportion to the emissions they cause, and adopting product standards that ban products that would otherwise cause unacceptably high emissions while clean alternatives are readily available.

Clean Energy Policies

Policies aiming to achieve a shift to clean energy will apply to many sectors such as transportation (including aviation), power plants, and industry and buildings which are also large consumers of fossil fuel. The above image also shows policies specifically targeting aviation, in addition to clean energy policies that apply across sectors.

The image below proposes feebates as the most effective way to accomplish the necessary shift to clean energy. In such feebates, fees are imposed on polluting energy and associated facilities, with revenues used - preferably locally - to fund rebates on clean energy and associated facilities.

In line with such feebates, each nation could impose fees on jetfuel, while using the revenues for a variety of purposes, preferably local clean energy programs. Where an airplane lands arriving from a nation that has failed to add sufficient fees, the nation where the airplane lands could impose supplementary fees. Such supplementary fees should be allowed under international trade rules, specifically if revenues are used to fund direct air capture of carbon dioxide.

Aviation Policies

As said, apart from clean energy policies, it makes sense to additionally implement policies specifically targeting aviation. Airplanes not only cause carbon dioxide emissions, but also cause other emissions such as black carbon and NOx, contrails and cirrus cloud effects. The EU emissions scheme only targets a limited set of emissions, while also looking at their global warming potential, rather than the potential of emissions to cause warming locally, specifically in the Arctic. A joint 2011 UNEP/WMO report mentioned many measures to reduce black carbon and tropospheric ozone, adding that their implementation could reduce warming in the Arctic in the next 30 years by about two-thirds.

A 2012 study by Jacobson et al. concludes that cross-polar flights by international aviation is the most abundant direct source of black carbon and other climate-relevant pollutants over the Arctic. Rerouting cross-polar flights to instead circumnavigate the Arctic Circle therefore makes sense. While such rerouting consumes more fuel, it could reduce fuel use and emissions within the Arctic Circle by 83% and delay pollutant transport to the Arctic.

Given the need to act on warming in the Arctic, it makes sense to ban cross-polar flights. To further reduce the flow of pollutants to the Arctic caused by aviation, it makes sense to add fees on all jet flights. Such fees on jet flights would be additional to the above fees on fuel. This could further facilitate a shift from aviation toward cleaner forms of transportation, such as high speed rail. Where the revenues of such fees are used to fund direct air capture, they could also help kickstart an industry that could produce synthetic jetfuel and that could be instrumental in bringing atmospheric levels of carbon dioxide back to 280ppm.


  1. Sam, incremental change to present policies won't keep Earth alive but fundamental changes at root core can frame a new structure of world enterprise

    Set the stage so to speak so civilization focuses.
    Here is how to do that as I described on Google*
    who by the way right now are trying to keep net up
    (apparently UN led by Russia want's to change it)

    Here is my comment from Google+ about how to win the game 2C if Earth is allowed to live on..
    Again, I don't think they mind cross position.
    Thank you Senator Sanders and your office staff for raising awareness of the critical state our Earth is in. However situation has developed with Earth's heat rise which puts CO2 reductions alone, voluntary or mandated unable to stop the Earth's slide into full blown Runaway. Emissions reductions alone are not enough. It will take emergency action to shield Earth from heat increase and to remove impediment to change at root core of monetary at least.. It'll take full force of industry and the efforts of all to undo Earth's abrupt climate change that we are already experiencing. -Unless there is concerted effort worldwide and root core Act of God implementation of changes to monetary value such strategic change won't be made.
    It is my contention the only way to key into driving force of enterprise worldwide to such an order of magnitude to save Earth now involves linking pecuniary value of money to money's value affect through use toward goal of trying to keep Earth's alive.. Ecosystem services alive. Both overt and underworld gov and mob need to buy into, really buy into the idea it would be fun to play 2C
    if Earth can be kept alive without harm to absolutely - man nor beast as best as possible- to the nth degree.. A fun game to take on and win. This needs to be focus in serious manner and is doable perhaps if full force of world civilization is aligned.. If focus is on children and ASAP.

  2. Time is of the essence to make change happen to keep Earth alive. Abrupt Climate Change is happening now and Arctic is critical.
    Air craft need to be zero emissions and capable of delivering cargo and emergency aid anywhere in the world and to back up ground transport and do errands such as emergency aid delivery and rescue.
    Fast build out of a fleet of near lighter than air craft utilizing Helium and even Hydrogen which are semi autonomous need to be made ready.
    Time is of the essence and past processes of life won't continue in future much longer without radical change to infrastructure of high finance and which at same time helps little guys and building of infrastructure capable of sustained quality improvement..
    Man's present business structure and system of finance has proven inadequate today. Emergency action is essential and framing a system to win.
    Disperse agreement based changes relying on local input from present collection of nations simply will fall flat as the UN conference of parties Climate Change summits demonstrated.
    To get the ball rolling and to break free of the chains that bind us a great alteration of contract law is needed and a changed focus now.
    Once that happens quality important improvement focused on what benefits Earth alive can zoom.
    To get in front of the gully washer of an extinction even now going runaway along with heat rise it will take a gully washer of an alteration to standing law,, law of contracts and strategic alteration to the value of money.
