气候友好型航空旅行的黎明

蒙特利尔—随着世界日益互通,航空旅行需求也在增长,未来几年预计将有超过30,000架新的大飞机上天。但如果想要保持航空旅行增长又不加剧全球变暖,就必须迅速降低与航空有关的二氧化碳排放。与航空有关二氧化碳排放量巨大,并且没有写入去年12月190多个国家达成一致的巴黎气候协定

幸运的是,现在是让航空排放与航空旅行增长脱钩的理想时机。本周,来自191个国家的代表齐聚蒙特利尔出席第39届联合国国际民用航空组织(ICAO)会议;在经历了几十年的争论后,他们就一项专门针对航空的气候协定达成了一致。

这一新ICAO框架的目标是从2020年开始实现国际航程的“碳中性增长”,其核心是一项基于全球市场的措施(GMBM),帮助航空公司以可承受的成本将净排放限制在2020年水平。该措施实施后将是第一项不给消费者带来成本显著上升的全球行业排放上限。航空公司将从其他经济部门购买减排量,从而引导数十亿美元用于全球低碳发展。

    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.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    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.
