Der Beginn des klimafreundlichen Flugverkehrs

MONTREAL – Während sich die Welt immer stärker miteinander verbindet, wächst die Nachfrage nach Flugreisen, und es wird erwartet, dass sich in den nächsten paar Jahren über 30.000 neue große Flugzeuge in die Lüfte erheben. Wenn wir aber nicht wollen, dass der wachsende Flugverkehr die globale Erwärmung verschärft, müssen wir schnell die erheblichen damit verbundenen CO2-Emissionen verringern, die nicht im Pariser Klimaabkommen berücksichtigt sind, auf das sich im letzten Dezember über 190 Länder geeinigt haben.

Glücklicherweise ist jetzt die perfekte Zeit, um die Flugemissionen vom Wachstum des Flugverkehrs abzukoppeln. Vertreter von 191 Ländern trafen sich in dieser Woche zur 39. Sitzung der Internationalen Organisation für zivile Luftfahrt der Vereinten Nationen (ICAO) in Montreal, und nach Jahrzehnten des Gerangels konnten sie sich auf ein luftverkehrsspezifisches Klimaabkommen einigen.

Ziel des neuen ICAO-Rahmenwerks ist ein „kohlenstoffneutrales Wachstum“ im internationalen Luftverkehr ab 2020. In seinem Mittelpunkt steht eine globale marktbasierte Messgröße (GMBM), die dazu beitragen soll, dass die Fluggesellschaften ihre Nettoemissionen auf finanziell tragbare Weise auf dem Niveau von 2020 einfrieren können. Nach ihrer Einführung wird dies die erste kohlenstoffbezogene Emissionsobergrenze eines weltweiten Wirtschaftszweigs sein, die die Kosten für die Kunden nicht merklich erhöht. Fluggesellschaften werden Emissionsreduktionen von anderen Wirtschaftssektoren erwerben und so Milliarden von Dollar in die Entwicklung kohlenstoffarmer Technologien in aller Welt leiten.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
