Recent development of accurate instruments for measuring greenhouse gas concentrations and the ability to mount them in ground-based vehicles has provided an opportunity to make temporally and spatially resolved measurements in the vicinity of suspected source locations, and for subsequently estimating the source location and strength.^The basic approach of using downwind atmospheric measurements in an inversion methodology to predict the source strength and location is an ill-posed problem and results in large uncertainty.^In this report, we present a new measurement methodology for reducing the uncertainty in predicting source strength from downwind measurements associated with inverse modeling.^In order to demonstrate the approach, an inversion methodology built around a plume dispersion model is developed.^Synthetic data derived from an assumed source distribution is used to compare and contrast the predicted source strength and location.^The effect of introducing various levels of noise in the synthetic data or uncertainty in meteorological variables on the inversion methodology is studied.^Results indicate that the use of noisy measurement data had a small effect on the total predicted source strength, but gave rise to several spurious sources (in many cases 8-10 sources were detected, while the assumed source distribution only consisted of 2 sources).^Use of noisy measurement data for inversion also introduced large uncertainty in the location of the predicted sources.^A mathematical model for estimating an upper bound on the uncertainty, and a bootstrap statistical approach for determining the variability in the predicted source distribution is demonstrated.^The new measurement methodology, which involves using measurement data from two or more wind directions, combined together as part of a single inversion process is presented.^Results of the bootstrap process indicated that the uncertainty in locating sources reduced significantly when measurements are made using the new proposed measurement approach.^The proposed measurement system can be significant in determining emission inventories in urban domains at a high level of reliability, and for studying the role of remediation measures.

The CleanEra project was initiated with the goal of developing revolutionary ideas for civil aviation. These ideas were to offer solutions which would limit and reduce some of the negative aspects of aviation, namely: emissions and the use of resources. This book presents you with the highlights of this journey in search of new technologies for a revolutionary aircraft; an aircraft that not only offers a future of comfortable air travel for the passenger, but a future of sustainable aviation for the planet as well.

This essay provides an overview of the major emissions trading programs of the past thirty years on which significant documentation exists, and draws a number of important lessons for future applications of this environmental policy instrument. References to a larger number of other emissions trading programs that have been implemented or proposed are included.

While the aviation sector has introduced a number of technological and operational measures to curb its greenhouse gas emissions, these will not offset the emissions expected from its projected growth. This book examines the legal framework underlying the international aviation and climate change discourse. It analyzes the suitability of the International Civil Aviation Organization's (ICAO) institutional setting to address climate change and provides a critical assessment of the European Union Emission Trading Scheme. Finally, the book makes several recommendations to facilitate the adoption,

Carbon Pricing reflects upon and further develops the ongoing and worthwhile global debate into how to design carbon pricing, and how to utilize the financial proceeds in the best possible way for society. The world has recently witnessed a significant downward adjustment in fossil fuel prices, which has negative implications for the future of our environment. In light of these negative developments, it is important to understand the benefits of environmental sustainability through well-documented research. This discerning book considers the design of carbon taxes and examines the consequential outcomes of different taxation compositions as regulatory instruments. Expert contributors assess a variety of national experiences to provide an empirical insight into the use of carbon taxes, emissions trading, energy taxes and excise taxes. The overarching discussion concludes that successful policies used by some countries can be implemented in other jurisdictions with minimum new research and experimentation
