Nous ne sommes guère plus avancés qu’il y a six ans / Jean Tirole, TSE debate, 14/12/2015

La COP 21 se devait de déboucher sur un accord efficace, juste et crédible. Mission accomplie ? L’accord annoncé est ambitieux. L’objectif à atteindre est maintenant « bien en dessous des 2 °C » et le monde devrait ne plus produire d’émission de gaz à effet de serre (GES) en net après 2050 ; les fonds dédiés aux pays en voie de développement dépasseront après 2020 les 100 milliards de dollars par an qui avaient été décidés à Copenhague en 2009… lire la suite

The Paris Agreement: historic! What’s next? / Iddri, Climate 365, 14/12/2015

A historic climate agreement was struck on Saturday the 12th of December in Paris. After four years of talks and two weeks of negotiations in Paris, the agreement represents a decisive reinforcement of the foundation for international climate policy. This article presents an analysis of the Paris Agreement and its negotiation, and of what should come next. Rather than analysing in detail its individual elements, it takes a step back to look at the bigger picture… lire la suite

COP-21 : que vaut l’accord de Paris ? / Sylvestre Huet,  {SCIENCES²}, 14/12/2015

Ce texte ( ici l’Accord de Paris en français) constitue certainement un progrès considérable au regard de l’impasse dans laquelle se trouvait le processus onusien depuis la COP-15 de Copenhague. Si les discussions s’étaient poursuivies, avec la réaffirmation des objectifs de la Convention, le plan d’action post-protocole de Kyoto restait en rade. L’Accord de Paris relance l’action, sur la base d’un consensus général. C’était le premier des objectifs de la COP-21, il est atteint… lire la suite

Failure to address global warming will cost many lives / Damian Tago, Thomas Alban, TSE debate, 14/12/2015

Climate change kills. In 2005 the World Health Organisation estimated that climate change caused by human activity claims more than 150,000 lives annually. More recently, the Climate Vulnerability Monitor placed the death toll at around 400,000. Using the Value of Statistical Life proposed by the US Environmental Protection Agency, this represents a cost of more than $3 trillion. Independent of the source, inaction on climate change is expected to increase death and suffering… lire la suite

Inciter les consommateurs à adopter des comportements écologiques peut avoir des effets indésirables / Céline Nauges, Sarah Ann Wheeler, TSE debate, 14/12/2015

La réduction des émissions de CO2 exigera des changements fondamentaux dans le comportement des consommateurs, des producteurs et des États. En règle générale, les économistes favorisent les incitations de type économique (essentiellement par les prix) pour inciter les ménages à adopter des comportements pro-environnementaux… lire la suite

Climat, réussite diplomatique et des pistes pour limiter le réchauffement / Jean-Pierre Bompard, blog Alter éco, 14/12/2015

Verre à moitié vide ou à moitié plein ? Comme dans tout accord négocié, chacun trouve facilement dans l’accord de Paris confirmation de ses préjugés optimistes ou pessimistes… lire la suite

Oil Prices and Global Growth / Kenneth Rogoff, Harvard University, Project Syndicate, 14/12/2015

One of the biggest economic surprises of 2015 is that the stunning drop in global oil prices did not deliver a bigger boost to global growth. Despite the collapse in prices, from over $115 per barrel in June 2014 to $45 at the end of November 2015, most macroeconomic models suggest that the impact on global growth has been less than expected – perhaps 0.5% of global GDP… lire la suite

Economists are from Mars, Electric Cars are from Venus / James Bushnell, Energy Institute at Haas, 14/12/2015

I work at UC Davis, a University with at least two (that I know about) centers devoted to research “aimed at developing a sustainable market for plug-in vehicles.” I run into a lot of researchers and environmental advocates who are completely dedicated to the mission of accelerating the deployment of electric vehicles. They view electrifying a large share of the transportation fleet as one key piece of the climate policy puzzle… lire la suite

Beyond the Paris agreement: COP21 shouldn’t be a milestone, but rather a launching pad for a new phase of climate action / Bruce Jones and Adele Morris, Planet Policy, 14/12/2015

Six years of on-again, off-again progress toward a global climate deal culminated in Paris, as negotiators for the United Nation’s opaquely named Conference of the Parties met in their 21st session. The deal struck by the UN Framework Convention on Climate Change (UNFCCC) scored a rare victory for global multilateral deal making… lire la suite

Toward a Green New Deal / Mariana Mazzucato, University of Sussex, Project Syndicate, 14/12/2015

The global agreement reached in Paris last week is actually the third climate agreement reached in the past month. The first happened at the end of November, when a group of billionaires led by Bill Gates, Mark Zuckerberg, and Jeff Bezos announced the creation of a $20 billion fund to back clean-energy research… lire la suite

The Net-Zero Imperative / Eric Beinhocker & Eric Beinhocker, University of Oxford, Project Syndicate, 14/12/2015

The world has reached an historic agreement on climate change. The deal concluded at the United Nations Climate Change Conference in Paris commits countries to take steps to limit warming to “well below” 2º Celsius relative to pre-industrial levels and to pursue “efforts” to limit warming to 1.5ºC. It also obliges developed countries to provide $100 billion per year in assistance to developing countries. But, unfortunately, the final negotiations dropped the one number that truly matters for the future of our planet: zero… lire la suite

Accord sur le climat : générations présentes 1 – générations futures 0 / Christian Gollier, TSE debate, 14/12/2015

Ce samedi 12 décembre 2015 a été dévoilé l’accord de la COP 21 de Paris. De nombreux acteurs parlent de succès, d’accord historique. Qu’en est-il concrètement ? Ce jour est-il effectivement à marquer d’une pierre blanche ? lire la suite
