El deber del G7 con la sostenibilidad

FRANKFURT – En seis meses, representantes de países de todo el mundo se reunirán en París en un intento de llegar a un acuerdo global para combatir el cambio climático. La semana entrante hay una reunión de los líderes del G7 en Alemania, y es una buena ocasión para comenzar a implementar medidas que eviten las consecuencias más peligrosas del calentamiento global. La seguridad y la prosperidad del mundo están en riesgo, y la cuestión ahora no es si hay que iniciar o no la transición a una economía de bajo carbono, o cuándo, sino cómo.

En 2014, las inversiones en energía limpia alcanzaron un nuevo máximo de 310 000 millones de dólares, tras dos años de caída. Es una buena noticia, pero sigue lejos de los 1,1 billones por año que según calcula la Agencia Internacional de la Energía (AIE) se necesitan en el sector de las energías no fósiles. En tanto, en 2013 se invirtieron unos 950 000 millones de dólares en petróleo, gas y carbón, el doble en términos reales que en 2000.

El valor de una inversión depende en gran medida de cuán riesgosa se la considera. Mientras los gestores de cartera sigan sin contabilizar los peligros del cambio climático, la inversión en fuentes de energía más ecológicas no despegará. Los inversores también deben prestar atención a las “burbujas fósiles”: la sobrevaluación de empresas extractivas derivada del supuesto de que podrán seguir quemando las reservas del mundo hasta que se agoten.

    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.

    • 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.
