Proposals to Eliminate Natural Gas from the Fuel Mix Are Premature / Andrew Campbell, Energy Institute at Haas blog, 17/10/2016

Natural gas is commonly called a “bridge” to a low carbon future. Why this metaphor? A bridge crosses over an obstacle, like a river or canyon. The metaphor suggests that transitioning from coal to natural gas for electric generation is one of the most cost-effective and scalable opportunities for cutting greenhouse gases on our way to the promised shore of even lower emissions… lire

New results on the net benefits of low-carbon electricity technologies / Charles Frank, Planet Policy, 17/10/2016

In my paper, “The Net Benefits of Low and No-Carbon Electrical Technologies,” (2014 Global Economy and Development Working Paper) I estimated the net benefits of five different electricity technologies: wind, solar, hydro, nuclear, and natural gas combined cycle. Natural gas combined cycle generated the most net benefits under a wide range of assumptions, despite a penalty of $50 per metric ton of CO2 emissions. Wind and solar technologies consistently ranked fourth and fifth among the five technologies… lire

As the Paris Agreement becomes reality: How to transform economies through carbon pricing / laura Tuck, Development in a changing climate, 17/10/2016

The remarkable pace at which nations of the world have ratified the Paris Agreement on climate change gives us all hope. It signals the world is ready to take the actions we need to keep global warming below 1.5 degrees Celsius. We know, however, that delivering on Paris comes with a high price tag, and that we need to help countries not just transition toward renewable energy but unlock the finance needed to get there… lire

Climate policy advisers need to take into account the real world trade-off between economic efficiency and political acceptability / Mark Jaccard, Policy Options, 11/10/2016

Last week, the House of Commons endorsed the Paris climate agreement, under which Canada commits to reduce greenhouse gases by 30 percent below 2005 levels by 2030. Simultaneously, Prime Minister Justin Trudeau abandoned hope that each province would voluntarily implement policies to achieve the national target. He said the federal government would, if necessary, impose a national charge of $10 per tonne of carbon dioxide in 2018, rising to $50 by 2022. After a year of niceties, realpolitik has arrived… lire

Why Now Is the Time to Make Energy Access in Cities a Top Priority / Michael Westphal, Sarah Martin and David Satterthwaite, WRI blog, 11/10/2016

Urban leaders from around the world are meeting in Quito, Ecuador, on October 17-20, 2016, to set the global agenda for the future of cities at the United Nations Conference on Housing and Sustainable Urban Development, known as Habitat III. Through the World Resources Report (WRR) on sustainable cities, WRI offers real-world research that aims to convert plans into implementation to create cities that live, move and thrive… lire

Climat : un meilleur graphique / Sylvestre Huet, {Sciences2}, 11/10/2016

Comment représenter au mieux l’évolution climatique en cours pour favoriser la réflexion sur la menace qu’elle représente ? James Hansen et Makiko Sato (Goddard Institute for Space Studies, Nasa) viennent de modifier leur traditionnel graphique montrant la courbe des températures de la planète depuis 1880. Ils n’ont pas changé la courbe elle même, mais la période de référence et également indiqué la moyenne glissante sur les 12 derniers mois… lire
