Le juste prix pour préserver notre climat

WASHINGTON, DC – Les dirigeants du monde entier se sont donné rendez-vous cette semaine à Paris à l’occasion de la <>Conférence des Nations Unies sur les changements climatiques avec pour mission de parvenir à un accord d’envergure mondiale capable de maîtriser les émissions de gaz à effet de serre. S’ils accomplissent cette mission, démontrant ainsi que les différents pays peuvent conjuguer leurs efforts dans l’intérêt de la planète, ils transmettront un puissant message d’espoir au monde entier — et à la population parisienne, qui manifeste une irréductible détermination après les récents attentats terroristes.

Les engagements en faveur du climat s’appuieront sur les contributions décidées au plan national (les Intended Nationally Determined Contributions ou INDC) dans le but de réduire les émissions à l’échelle mondiale. La tarification de ces émissions devrait, à mon sens, être au cœur de ces engagements.

Pour parvenir à diminuer les émissions de gaz à effet de serre au moindre coût il faudra engager une révolution de la consommation et de la production d’énergie. Une augmentation graduelle, prévisible et fiable des prix énergétiques devrait inciter les consommateurs à réduire leurs dépenses. Par ailleurs une tarification appropriée du carbone permettrait de s’affranchir de manière ordonnée des combustibles fossiles en encourageant les investissements dans les technologies novatrices.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
