Der richtige Zeitpunkt für Klimaschutzmaßnahmen

PARIS – In den rund drei Jahrzehnten, seit der Klimawandel zu einem globalen Thema wurde, gingen die Regierungen die meiste Zeit optimistisch davon aus, dass sich ein grüner Übergang im Laufe der Zeit von ganz allein einstellen wird, wenn steigende Preise für fossile Brennstoffe die Verbraucher in Richtung kohlenstoffarmer Alternativen drängen. Das Hindernis, so glaubte man, läge auf der Produktionsseite, da sprudelnde Renditen aus Investitionen in Ölfelder zu immer ehrgeizigeren Explorationsvorhaben führen würden.

Heute hat sich das Blatt gewendet. Angesichts eines bei rund 40 US-Dollar pro Fass stagnierenden Ölpreises brauchen die Unternehmen im Bereich fossiler Brennstoffe keine Regierungen, die ihnen einen Investitionsstopp nahelegen. Die Herausforderung liegt mittlerweile auf der Verbraucherseite der Gleichung. Angesichts derartig niedriger Treibstoffpreise, stellt sich die Frage, was zu tun ist, um Verbrauchsmuster zu verändern.

Natürlich gibt es einige Anzeichen dafür, dass billigere Energie für ausreichend Wachstum sorgen könnte, um die Ölpreise wieder nach oben zu treiben. Doch niemand prognostiziert, dass der Wiederanstieg hoch genug ausfallen wird, um jene radikale Transformation in Gang zu bringen, derer es bedarf, damit die Länder ihre Ziele zur Reduktion der Emissionen erreichen.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
