From Good Intentions to Deep Decarbonization / Jeffrey D. Sachs, Guido Schmidt-Traub &#38; Jim Williams, Project Syndicate, 1/12/2015In the run-up to the United Nations Climate Change Conference (COP21) in Paris, more than 150 governments submitted plans to reduce carbon emissions by 2030. Many observers are asking whether these reductions are deep enough. But there is an even more important question: Will the chosen path to 2030 provide the basis for ending greenhouse-gas emissions later in the century?... lire la suiteCap and Trade: Lessons of Experience / Timothy Taylor, Conversable Economist, 1/2/2015A key question for a number of policy-makers, especially those contemplating the current negotiations in Paris about climate change issues, is whether a cap-and-trade approach might be a useful tool for reducing national emissions of carbon and other greenhouse gases in a cost-effective way. For example President Xi Jinping announced a couple of months ago that China will launch a national CO2 cap-and-trade system covering key industries in 2017... lire la suiteIndia’s carbon commitment framework: Realistic, but is it enough? / Rahul Tongia, Planet Policy, 1/12/2015Paris is again in the news, but hopefully for something positive, as world leaders gather for the global COP21 climate negotiations. Many feel it is now or never. But the question remains, who is supposed to contribute how much toward emissions reductions?... lire la suiteParis 2015: What's in it for Europe? / Tim Boersma, Brookings blog, 1/12/2015On November 30, thousands of diplomats, activists, and politicians gather in Paris to conclude what is expected to be a new global agreement to address climate change. The good news is that there seems to be momentum to make meaningful progress in reducing greenhouse gas emissions... lire la suite Carbon and inequality: From Kyoto to Paris / Lucas Chancel &#38; Thomas Piketty, Vox, 1/12/2015The COP21 conference faces a severe problem when it comes to funding climate adaptation in developing countries. This column examines novel strategies to increase the funding. The strategies are based on high individual carbon emitters wherever they are in the world, rather than according to the responsibilities of high-emitting countries. To this end, a global distribution of individual income and CO2e emissions is constructed... lire la suiteCOP21: peut-on parler de droits de l'humanité? / Marc Clément, magistrat administratif, Telos, 1/12/2015Dans une indifférence quasi générale, Corinne Lepage, missionnée en juin par le Président de la République, a remis en septembre son rapport et sa proposition de déclaration universelle des droits de l'humanité. Cette proposition s'inscrit dans le cadre de la COP21 et vise à développer une nouvelle génération de droits que la résolution des questions environnementales imposerait... lire la suiteThe Right Price for Preserving Our Climate / Christine Lagarde, Project Syndicate, 30/11/2015When world leaders convene in Paris this week for the United Nations Climate Change Conference, their task will be to reach a global agreement on curbing greenhouse-gas emissions. A successful outcome, demonstrating that countries can work together for the good of the planet, would send a powerful message of hope to the world – and to the people of Paris, who remain unbowed after the recent terrorist attacks... lire la suiteCOP21 : dépassons les déclarations d’intentions / Jean Tirole et CHristian Gollier, The Conversation, 27/11/2015Le rendez-vous de la COP21 est tout proche, et la crainte que cette conférence internationale se réduise à une simple liste d’intentions grandit. Les négociations actuelles fondées sur des « contributions volontaires » (INDC) permettent de faire des promesses séduisantes et de crier victoire alors, qu’en réalité, elles servent surtout à pérenniser l’attentisme de la communauté internationale... lire la suiteChina’s Latest Five-Year Plan / Martin Feldstein, Professor of Economics at Harvard University, Project Syndicate, 28/11/2015I was in Beijing last month when the Chinese government released a preliminary summary of its 13th Five-Year Plan. This is an important document for understanding where China is headed in the 2016-2020 period. And yet China’s five-year plans just aren’t what they used to be... lire la suitePutting China’s coal consumption into context / Qi Ye and Tong Wu, Brookings blog, 30/11/2015Few issues are more likely to provoke interest about China—though often of a sensational and ill-informed variety—than its coal use and national statistics. The former evokes images of smog-oppressed cities, vividly highlighting the dangers of heedless industrial growth. The latter prompts cynicism about the reliability of official Chinese accounting, reinforcing preconceptions about a less-than-transparent system of governance. Indeed, both call into the question China’s transparency: one literal, the other metaphorical... lire la suiteLa Russie va se servir de ses vastes forêts comme monnaie d’échange / Marianna Poberezhskaya,Lecturer in International Relations, Nottingham Trent University, The Conversation, 27/11/2015La Russie est réputée pour être l’un des États les plus difficiles en matière de négociations climatiques, et il ne faut s’attendre à aucun changement lors de la COP21. Après tout, le pays possède de vastes réserves de pétrole et de gaz, subit des hivers rigoureux et défend âprement ses intérêts économiques... lire la suite
