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.

Given the current global warming context and greenhouse gas obligations for organisations, the Luxembourg Institute of Science and Technology established a carbon footprint that revealed a high emission related to its electricity consumption within its laboratory research building. As a result, the LIST has set itself the goal of reducing its consumption and greenhouse gas emissions through a variety of sustainable actions. We used the DMAIC method in conjunction with the EN16247 energy audit method to accomplish this. This combination revealed a lack of data on the Belvaux site's electricity consumption and greenhouse gas emissions. The proposals for improvement thus focused on three levels of correction and improvement: the implementation of centralized management and measurement, consumption reduction, and the implementation of renewable electricity production systems. In conclusion, thanks to this method we have been able to implement adapted and sustainable improvements to reduce the carbon footprint of this Institute. However, while this approach was sufficient to reduce unnecessary consumption, additional improvements could be considered to make this building environmentally responsible and energy efficient.

Under Executive Order 12866, agencies are required, to the extent permitted by law, ""to assess both the costs and the benefits of the intended regulation and, recognizing that some costs and benefits are difficult to quantify, propose or adopt a regulation only upon a reasoned determination that the benefits of the intended regulation justify its costs."" The purpose of the ""social cost of carbon"" (SCC) estimates presented here is to allow agencies to incorporate the social benefits of reducing carbon dioxide (CO2) emissions into cost-benefit analyses of regulatory actions that have small,
