Pour un avenir nanotechnologique sûr

Nous vivons, dit-on, au bord d’une révolution nanotechnologique, où la matière est manipulée à une échelle des milliers de fois plus petite que ce que peut voir l’œil humain, et où des matériaux familiers se conduisent d’étranges façons. Cette révolution, si elle est couronnée de succès, va bouleverser notre monde.

Les nanotechnologies renforcent notre contrôle du monde matériel, permettent d’améliorer les technologies existantes et d’en développer de nouvelles. Les possibilités semblent illimitées, depuis la construction de matériaux plus solides et plus légers et la fabrication d’ordinateurs incroyablement petits et immensément puissants, jusqu’au développement de nouvelles sources d’énergie renouvelable et à la conception de soins personnalisés pour combattre le cancer.

La valeur des nanotechnologies intégrées à des produits manufacturés dépasse les 50 milliards de dollars. Plus de 500 produits de consommation comportant des nanotechnologies signalées par les fabricants sont aujourd’hui sur le marché, des cosmétiques aux éléments de voiture en passant par la vaisselle. En se basant sur les recherches de scientifiques de quelque 100 nations du monde, on estime que d’ici 2014 la valeur des produits manufacturés utilisant ces technologies dans le monde dépassera les 2,6 billions de dollars (soit 15 % de la production totale). Si les projections actuelles sont exactes, les nanotechnologies sont potentiellement capables d’avoir un impact dans presque toutes les industries et d’influencer pratiquement tous les aspects de nos vies.

    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.
