Malgr\u00e9 les engagements climatiques annonc\u00e9s, les \u00e9missions mondiales de gaz \u00e0 effet de serre ne devraient baisser que de 10% d’ici 2035, bien loin des 60% n\u00e9cessaires pour limiter le r\u00e9chauffement \u00e0 1,5C , selon le constat du Giec, le groupe d’experts intergouvernemental sur l’\u00e9volution du climat des Nations unies.<\/strong><\/p>\n\n\n\n

A quelques jours du sommet de la COP30, l’ONU a \u00e9valu\u00e9 les plans nationaux d\u00e9pos\u00e9s \u00e0 l’heure, \u00e0 fin septembre, qui fixent un objectif de r\u00e9duction des \u00e9missions de gaz \u00e0 effet de serre et d\u00e9taillent les moyens d’y parvenir. \u00ab\u00a0Mais plus d’une centaine de pays manquent \u00e0 l’appel\u00a0\u00bb.
L’ONU n’a donc pu inclure que les donn\u00e9es de 64 pays dans sa synth\u00e8se et est incapable d’actualiser la trajectoire de r\u00e9chauffement du monde, estim\u00e9e l’an dernier \u00e0 2,1-2,8 C d’ici \u00e0 la fin du si\u00e8cle. Les donn\u00e9es compil\u00e9es, qui refl\u00e8tent les engagements de pays repr\u00e9sentant moins d’un tiers des \u00e9missions mondiales, \u00ab\u00a0donnent une image assez limit\u00e9e\u00a0\u00bb, reconna\u00eet Simon Stiell, le secr\u00e9taire ex\u00e9cutif de l’ONU Climat.
Pour avoir une image plus compl\u00e8te, l’ONU a fait des calculs incluant les lettres d’intention et l’engagement de certains pays. \u00ab\u00a0Cette image plus large, bien qu’encore incompl\u00e8te, montre que les \u00e9missions mondiales devraient baisser d’environ 10% d’ici 2035\u00a0\u00bb, indique Simon Stiell.
\u00ab\u00a0L’humanit\u00e9 est clairement en train d’infl\u00e9chir la courbe des \u00e9missions \u00e0 la baisse pour la premi\u00e8re fois, m\u00eame si cela reste encore loin d’\u00eatre suffisant\u00a0\u00bb, a-t-il soulign\u00e9. Ces conclusions nourriront les vifs d\u00e9bats de la COP30, la grande conf\u00e9rence annuelle de l’ONU pour laquelle des pays europ\u00e9ens et petites \u00eeles expos\u00e9es aux ravages climatiques exigent que la question de la baisse des \u00e9missions, et donc des \u00e9nergies fossiles, soit d\u00e9battue.<\/p>\n","protected":false},"excerpt":{"rendered":"
