Die Klimapolitik-Falle

ROM – Die Kosten der heutigen Strategien im Kampf gegen den Klimawandel sind weitaus höher als ihr Nutzen. Bedauerlicherweise führen schlechte politische Entscheidungen häufig dazu, diese Strategien noch weniger kosteneffizient werden zu lassen.

Nehmen wir beispielsweise die 20-20-Politik der Europäischen Union, die darauf abzielt, die CO2-Emissionen bis zum Jahr 2020 unter das Niveau von 1990 zu verringern. Es ist wichtig, diesen Ansatz näher zu beleuchten; nicht nur, weil die EU die umfangreichste und ehrgeizigste Klimapolitik weltweit verfolgt, sondern auch weil andere Klimapolitiken ähnliche Mängel aufweisen.

Die kosteneffizienteste Weise, das 20%-Ziel zu erreichen wäre ein EU-weit einheitlicher Kohlenstoffmarkt, der die EU bis zum Jahr 2020 etwa 96 Milliarden US-Dollar kosten würde. Der Nutzen für die ganze Welt wäre allerdings deutlich geringer. Schätzungen des einzigen durch Experten begutachteten Überblicks über die EU-Klimapolitik zufolge, kann diese pro Jahr Kosten in Höhe von etwa 10 Milliarden US-Dollar vermeiden, die durch Klimaschäden entstehen würden. Also wird die EU für jeden ausgegebenen Dollar Schäden im Wert von etwa zehn Cent vermeiden.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
