负责投资者的气候变化指南

纽约—放眼全球,机构投资者——包括养老基金、保险公司、慈善捐赠基金和大学——正在纠结一个问题:是否将投资从石油、天然气和煤炭公司转移。当然,原因就在气候变化:除非化石燃料消费大幅削减——并在2070年前后彻底杜绝,转而利用太阳能等零碳能源——否则认为导致的全球变暖给地球造成的风险将是难以接受的。负责任的投资者应该如何面对这些前所未有的风险采取行动?

取消投资确实是一个答案,原因是多样的。一是单纯出于自利:在一个决然向可再生能源转移的世界中,化石燃料行业是一项坏投资。(尽管也有例外;比如,最贫穷国家的化石燃料开发将继续存在,即使富国被要求削减开发,这是为了推进减贫。)

此外,取消投资还可以通过让该行业得不到投资资本而有助于加速这一转变——或至少提高在削减生产的迫切要求下仍然进行不负责任的石油、天然气和煤炭勘探开发的企业的资本成本。尽管单独看,每一家机构投资者都无法带来重大变化,但几百家大型投资者手中的数万亿美元资产一定可以。

    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.
