Licht ins Dunkel des Klimawandels

NEW YORK – Eine Glühbirne kommt einen nicht gerade als erstes in den Sinn, wenn man an revolutionäre Technologien denkt.  Doch in der Welt von heute verfügen Wissenschaft und intelligente Politik über das Potenzial, einen gewöhnlichen Haushaltsgegenstand in ein Objekt revolutionärer Innovation zu verwandeln.

Vor kurzem besuchte ich ein ehrgeiziges Projekt zur Förderung energiesparender Beleuchtung in China. Durch die schrittweise Abschaffung der herkömmlichen Glühbirne und Einführung einer neuen Generation von Lichtquellen erwartet sich China eine Senkung seines nationalen Energieverbrauchs um 8 Prozent.  

Das kann tief greifende globale Auswirkungen haben. Man bedenke Folgendes: 19 Prozent des weltweiten Energieverbrauchs wird für Beleuchtung verwendet. Wissenschaftler erklären, wir könnten diesen Anteil durch eine einfache Maßnahme wie den Austausch von Glühbirnen um ein Drittel oder noch mehr verringern.

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies.

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.
