Prix interne du carbone : pourquoi et comment ? / Raphaël Olivier, Informations et Débats, n° 55, mai 2018, 22 p. https://www.chaireeconomieduclimat.org/publications/prix-interne-du-carbone-pourquoi-et-comment/

Mettre un prix sur ses propres émissions de carbone est une pratique émergente dans les grandes entreprises. Les applications concrètes de cette démarche volontaire sont toutefois hétérogènes, d’où l’intérêt de la catégoriser conceptuellement…

After the Paris Agreement: measuring the global decarbonization wedges from national energy scenarios / S. Mathy, P. Menanteau & P. Criqui, Ecological economics, vol. 150, August 2018, pp. 273-289  https://www.sciencedirect.com/science/article/pii/S092180091730366Xhttps://authors.elsevier.com/a/1X2wp_KzPPdtc~

The new bottom-up approach of the Paris agreement calls for a better understanding of the domestic dimension of development pathways and of the implications for global emissions trajectory. To this end, it is of strategic importance to provide a common framework that makes it possible to identify the key decarbonization wedges at the national level and to highlight the potential benefits of international cooperation. The article proposes an advanced index decomposition analysis methodology based on sectoral energy service indicators and on a specific decomposition in the power sector for quantifying the contribution of different mitigation strategies. It is applied to national deep decarbonization pathways elaborated in the Deep Decarbonization Pathway Project (DDPP) by the sixteen largest GHG emitting countries. In a global perspective, the results reveal the key role of energy efficiency and decarbonization of energy carriers in the industry sector, deployment of renewables in the power sector and, to a lesser extent, coal/gas substitution, and efficiency and energy decarbonization in the transport sector. The analysis also calls for a deeper understanding of the role a reduction in energy-service demand can play in mitigation scenarios and of the respective contribution for industry of energy efficiency and structural change.

The carbon footprint of global tourism / Manfred Lenzen, Ya-Yen Sun, Futu Faturay, Yuan-Peng Ting, Arne Geschke and Arunima Malik, Nature Climate Change, 7 May 2018 https://doi.org/10.1038/s41558-018-0141-x

Tourism contributes significantly to global gross domestic product, and is forecast to grow at an annual 4%, thus outpacing many other economic sectors. However, global carbon emissions related to tourism are currently not well quantified. Here, we quantify tourism-related global carbon flows between 160   countries, and their carbon footprints under origin and destination accounting perspectives. We find that, between 2009 and 2013, tourism’s global carbon footprint has increased from 3.9 to 4.5 GtCO2e, four times more than previously estimated, accounting for about 8% of global greenhouse gas emissions. Transport, shopping and food are significant contributors. The majority of this footprint is exerted by and in high-income countries. The rapid increase in tourism demand is effectively outstripping the decarbonization of tourism-related technology. We project that, due to its high carbon intensity and continuing growth, tourism will constitute a growing part of the world’s greenhouse gas emissions.

Vers un 2e plan d’adaptation au changement climatique pour la France : enjeux et recommandations – Rapport au Premier ministre et au Parlement / France. Observatoire national sur les effets du réchauffement climatique. Paris : La Documentation française, novembre 2017, 229 p. http://www.ladocumentationfrancaise.fr/rapports-publics/184000253/index.shtml

Cet ouvrage rassemble les recommandations issues de la concertation nationale pour un deuxième plan national d’adaptation au changement climatique (PNACC). Celle-ci s’est largement appuyée sur les évaluations du premier PNACC 2011-2015 permettant d’avoir un retour d’expériences d’un cycle complet de politique publique. Selon l’ONERC, cette situation fait de la France un des pays les plus avancés en matière de planification de l’adaptation au changement climatique. La concertation a également bénéficié d’une prise de conscience renforcée, en grande partie grâce à l’accord de Paris qui met en avant, dans son article 7, la nécessité d’un engagement accru en matière d’adaptation.
