L'Europa deve uscire dall'impasse sul cambiamento climatico

LONDRA – L’Europa vanta una lunga tradizione come leader nella lotta contro il cambiamento climatico. Ultimamente, però, il dibattito su come risolvere il problema è giunto a un punto morto, dove sostenibilità ambientale e crescita sembrano spesso escludersi a vicenda. Se vuole mantenere la propria posizione di leadership in ambito ambientale, e continuare a essere un polo d’innovazione e competitività, l’Europa dovrà abbandonare la sua rigidità ideologica e abbracciare soluzioni realistiche e pragmatiche in grado di apportare vantaggi ambientali senza compromettere lo sviluppo economico.

Le sfide legate al cambiamento climatico sono reali, e le conseguenze della mancanza d'interventi in tal senso impossibili da ignorare. Allo stesso tempo, la domanda di energia è in aumento e c’è un disperato bisogno di uscire dall’attuale crisi economica in modo definitivo. Non esiste una soluzione unica né facile per questi due imperativi. Frenare il riscaldamento globale garantendo, al tempo stesso, la crescita economica richiederà una gamma ben calibrata di soluzioni, tra cui quelle che si basano sulle energie rinnovabili e su una maggiore efficienza energetica. Tra queste opzioni, la tecnica della cattura e dello stoccaggio dell'anidride carbonica (CCS) ha un ruolo centrale.

La tecnologia CCS cattura il diossido di carbonio all’origine dell’emissione, lo comprime e lo immagazzina sottoterra in modo permanente. Così facendo, stabilisce un importante collegamento tra la nostra economia moderna, basata perlopiù su combustibili fossili ad alta intensità di carbonio, e un futuro in cui le emissioni di CO2saranno molto ridotte. In altri termini, essa offre la possibilità di mantenere un settore industriale competitivo e, al tempo stesso, combattere il riscaldamento globale.

    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.
