Private Governance Responses to Climate Change: The Case of Global Civil Aviation

This Article explores how private governance can reduce the climate effects of global civil aviation. The civil aviation sector is a major contributor to climate change, accounting for emissions comparable to a top ten emitting country. National and international governmental bodies have taken important steps to address civil aviation, but the measures adopted to date are widely acknowledged to be inadequate. Civil aviation poses particularly difficult challenges for government climate mitigation efforts. Many civil aviation firms operate globally, emissions often occur outside of national boundaries, nations differ on their respective responsibilities, and demand is growing rapidly. Although promising new technologies are emerging, they will take time to develop and adopt. This Article argues that private initiatives can overcome many of these barriers. Private initiatives can motivate civil aviation firms to act absent government pressure at the national level and can create pressure for mitigation that transcends national boundaries. The Article argues that it is time to develop a private climate governance agenda for civil aviation and identifies examples of the types of existing and new initiatives that could be included in the effort. If public and private policymakers can overcome the tendency to focus almost exclusively on public governance, private initiatives can yield large and prompt emissions reductions from global civil aviation, buy time for more comprehensive government measures, and complement the government measures when they occur

Forks in the Road

This Essay outlines a simple heuristic that will enable public and private policymakers to focus on the most important climate change mitigation strategies. Policymakers face a dizzying array of information, pressure from advocacy groups, and policy options, and it is easy to lose sight of the forest for the trees. Many policy options are attractive on the surface but either fail to meaningfully address the problem or are unlikely to be adopted in the foreseeable future. If policymakers make the right decision when confronting three essential choices or forks in the road, though, the result will be 60% to 70% reductions in greenhouse gas emissions, an amount that will keep widely-adopted climate mitigation goals in reach. The three options are decarbonization of the electrical grid, electrification of the motor vehicle fleet, and electrification of buildings. International, national, and subnational officials, philanthropists, corporate executives, advocacy group leaders, and households all have the ability to prioritize these three options in their regulatory, purchasing, and other actions. If they choose these three decarbonatization options, many other mistakes can be made without jeopardizing the achievement of widely adopted emissions targets. If they make the wrong choice, however, few combinations of other viable options can achieve the necessary reductions. In the face of a growing consensus that immediate, major emissions reductions are required, the forks in the road heuristic can provide policymakers with the framework necessary to make smart decisions and ignore the noise surrounding climate law and policy

Symposium - Supply and Demand: Barriers to a New Energy Future

Like many fields, energy law has had its ups and downs. A period of remarkable activity in the 1970s and early 1980s focused on the efficiencies arising from deregulation of energy markets, but the field attracted much less attention during the 1990s. In the last decade, a new burst of activity has occurred, driven largely by the implications of energy production and use for climate change. In effect, this new scholarship is asking what efficiency means in a carbon- constrained world. Accounting for carbon has induced scholars to challenge the implicit assumption of the early scholarship that the price of energy reflects all important externalities, and that efficiency therefore can be assumed to mean the generation of the most energy at the lowest cost. Accounting for carbon also has contributed to the growing nexus between energy and environmental law, and has called on practitioners, regulators, and scholars to develop new regulatory solutions that integrate these previously distinct areas. This reconceptualization of energy law in light of carbon constraints has inspired two important areas of scholarship. The Vanderbilt Energy, Environment and Land Use Program, the Vanderbilt Climate Change Research Network, and the Vanderbilt Law Review organized this Symposium, Supply and Demand: Barriers to a New Energy Future, to address both areas. Robert Socolow\u27s keynote address sets the stage for the articles that follow by explaining the urgency and priority of reducing carbon emissions. Socolow\u27s address draws on the literature from numerous disciplines to demonstrate that climate change involves hard truths, and he argues that we must become better at telling those truths to ourselves

What can we learn from relaxation measurements of a laser-perturbed atmosphere? A modeling study

The chemical kinetic aspects of a transient increase in OH and HO2 by several orders of magnitude are explored in three model tropospheres. This chemical kinetic modeling effort was undertaken to support the operation of a pump-and-probe LIDAR instrument. A powerful excimer laser pulse perturbs the troposphere after which its relaxation back to steady state is examined by remote sensing, for example by DIAL or LIF. Instead of probing ambient levels of key free radicals, a study of the relaxation kinetics in real time enables chemical mechanistic studies in situ

The Use of Odors to Induce Avoidance Behavior in Pine Voles

Commercial orchards, ornamental nurseries, and residential horticulture in North Carolina experience economic losses due to pine vole (Microtus pinetorum) depredation. Predator odors and the herbicide Casoron were tested as potential repellents for pine voles. To test for avoidance behavior, animals were allowed to build a nest in one of two chambers attached to each arm of a Y-maze. The cage containing the nest was treated with either a test repellent compound, methylene chloride (solvent control), or left unmanipulated (control). Animals were categorized as either maintaining or changing nest cage preference between pre-test and test periods. The number of animals that changed cage preference in the control group was compared to the treatment groups. Only the Casoron treatments were significantly different, with approximately 50% of the animals changing preference. The difference in time spent in the nest cage during the pre-test and test periods for the treatment groups were compared to control groups. The Casoron and DTT treatments resulted in significant time differences. These results indicate that Casoron has repellent potential and warrants further investigation into its effectiveness in the field. The predator odors tested showed little promise as repellents

A Hybrid GA-PSO Method for Evolving Architecture and Short Connections of Deep Convolutional Neural Networks

Image classification is a difficult machine learning task, where Convolutional Neural Networks (CNNs) have been applied for over 20 years in order to solve the problem. In recent years, instead of the traditional way of only connecting the current layer with its next layer, shortcut connections have been proposed to connect the current layer with its forward layers apart from its next layer, which has been proved to be able to facilitate the training process of deep CNNs. However, there are various ways to build the shortcut connections, it is hard to manually design the best shortcut connections when solving a particular problem, especially given the design of the network architecture is already very challenging. In this paper, a hybrid evolutionary computation (EC) method is proposed to \textit{automatically} evolve both the architecture of deep CNNs and the shortcut connections. Three major contributions of this work are: Firstly, a new encoding strategy is proposed to encode a CNN, where the architecture and the shortcut connections are encoded separately; Secondly, a hybrid two-level EC method, which combines particle swarm optimisation and genetic algorithms, is developed to search for the optimal CNNs; Lastly, an adjustable learning rate is introduced for the fitness evaluations, which provides a better learning rate for the training process given a fixed number of epochs. The proposed algorithm is evaluated on three widely used benchmark datasets of image classification and compared with 12 peer Non-EC based competitors and one EC based competitor. The experimental results demonstrate that the proposed method outperforms all of the peer competitors in terms of classification accuracy
