What Would it Take to Reduce US Greenhouse Gas Emissions 80% by 2050? / Geoffrey Heal. NBER, Aug. 2016 (Working Paper No. 22525) http://www.nber.org/papers/w22525
I investigate the cost and feasibility of reducing US GHG emissions by 80% from 2005 levels by 2050. The US has stated in its Paris COP 21 submission that this is its aspiration, and Hillary Clinton has chosen this as one of the goals of her climate policy. I suggest that this goal can be reached at a cost in the range of $42 to $176 bn/year, but that it is challenging. I assume that the goal is to be reached by extensive use of solar PV and wind energy (66% of generating capacity), in which case the cost of energy storage plays a key role in the overall cost. I conclude tentatively that more limited use of renewables (less than 50%) together with increased use of nuclear power might be less costly.
Aligning Transnational Climate Action with International Climate Governance: The Road from Paris / Sander Chan, Clara Brandi and Steffen Bauer, RECIEL 25 (2) 2016, pp. 238-247. http://onlinelibrary.wiley.com/doi/10.1111/reel.12168/epdf
Transnational climate actions have come to constitute a distinguishable sphere of climate governance. Reflecting on the Paris outcome, this article discusses the role of non-State and subnational actors – especially on the road to the Paris climate change conference. It argues that the intergovernmental and transnational spheres of global climate governance could mutually reinforce each other by continuing mobilization efforts to engage non-State actors and by harnessing greater ambition, both from State and non-State actors. For such mutual reinforcement to take effect, however, the United Nations Framework Convention on Climate Change should engage non- State actors consistently and systematically. The article also argues that the Paris outcome and, above all, the building blocks that are part of the decision on enhancing pre-2020 action, constitute the most comprehensive framework of non-State engagement yet, offering a promising basis for mutual reinforcement of the intergovernmental and transnational spheres of global climate governance.
Projections de la demande de transport sur le long terme / Rémi Pochez, Nicolas Wagner et Isabelle Cabanne. France. Ministère de l’environnement, de l’énergie et de la mer. Service de l’économie, de l’évaluation et de l’intégration du développement durable, juillet 2016, 170 p. http://www.developpement-durable.gouv.fr/IMG/pdf/Projections_demande_transport.pdf
Ce document présente les projections de la demande de transport de voyageurs et de marchandises aux horizons 2030 et 2050 réalisées par le Commissariat général au développement durable (CGDD). La synthèse qui est proposée ici en reprend les principaux résultats pour un scénario central à l’horizon 2030 et deux cadrages de la mobilité des passagers à courte distance et du fret à l’horizon 2050.
Maximizing the potential of the Paris Agreement: Effective review in a hybrid regime / H. van Asselt, T. Hale, K. Abbott, Y. Dagnet, M. Doelle, A.Abeysinghe, M. Milkoreit, C. Dihl Prolo, and B. Rudyk. Oxford : Stockholm Environment Institute, 2016, 6 p. (SEI discussion brief) https://www.sei-international.org/publications?pid=2992
This discussion brief identifies key questions still to be addressed about review processes under the Paris Agreement, and outlines a few options for answering them, focusing on review of implementation, ambition, and compliance.
