An Assessment of Carousel Value-Added Tax Fraud in The European Carbon Market
2017
AbstractThe literature on the European Union Emission Trading System (EU ETS) is by now very rich. Much is known about the efficiency, the effectiveness, and the environmental and distributional impacts of the EU ETS. Less, however, is known about the carousel value-added-tax (VAT) fraud phenomena in the European carbon market. This article evaluates the welfare effects of carousel VAT fraud in the EU ETS using a computable general equilibrium (CGE) analysis. According to our findings, if VAT fraud occurs in the EU ETS, the effects on welfare for the EU Member States are negative, with welfare loss significantly higher than the VAT fraud value. This article also discusses the reverse charge…
Statistics-driven Development of OBD Systems: An Overview
2006
Automotive on-board diagnostic (OBD) systems are designed to keep critical components under control during vehicle functioning, and to alert the driver in case of severe malfunctions. OBD systems aimed at reducing polluting emissions are mandatory on new motor vehicles. Some research projects conducted in cooperation between universities and the automotive industry have been quite successful in terms of knowledge advancement and industrial gain. An updated overview of the adopted methodologies and results obtained are given in this article. Such results can be valuable for both theorists and practitioners, since they witness the use of statistics as a powerful catalyst of technical progress…
Is there such a thing as sustainable physical activity?
2016
- This study aims to assess the prevalence of different modes of commuting to school and work for 10-12year-olds and their parents; to assess the associations with demographic variables (country, sex, parental education and ethnicity) and with weight status in eight European countries. As part of the ENERGY project a cross-sectional survey was conducted in 2010 in which modes of commuting and socio-demographic variables for children (N=7903) and one of their parents (n=6455) were measured by questionnaires. Children's weight and height were objectively measured; parents self-reported their weight and height. Logistic multilevel regression analyses assessed the associations between mode of c…
Household carbon footprints in the Baltic States: A global multi-regional input–output analysis from 1995 to 2011
2017
The paper analyzes consumption related household CO2 equivalent (CO2e) emissions for the three Baltic States – Estonia, Latvia and Lithuania from 1995 to 2011. The analysis is based on a multi-regional input–output model, which allows us to estimate life-cycle emissions for all major household consumption items. Results demonstrate that household carbon footprints in all the Baltic States significantly increased by 47% in Estonia, 20% in Latvia and 52% in Lithuania during the study period. In 2011 in Estonia expenditures for housing and utility contributed the highest per capita life-cycle emissions – 43%. However, in Lithuania housing accounted only for 16% of per capita emissions, but foo…
Application of the Structural Decomposition Analysis to assess the indirect energy consumption and air emission changes related to Italian households…
2012
Abstract The design of sustainable production and consumption strategies and the assessment of implemented actions require to identify the driving forces that influence the trend of energy consumption and environmental impacts. For this purpose, the Structural Decomposition Analysis (SDA) was developed as a suitable methodology to analyse the driving forces of the changes in economic, energy and environmental indicators. The paper presents one of the first Italian studies that apply an energy and environmental extended input–output model, opportunely shaped to the examined context, combined with SDA. In detail, it aims at: (1) investigating the energy use and the air emissions arisen from t…
Les commissions de quartier à l’épreuve de l’intelligence du social
2016
The notion of intelligence of social relationships enables to explore the communicative approach of participatory democracy. Citizen life is no longer only restricted to putting a ballot into a ballot box but is getting towards true cooperation between the various actors of public communication.
Baseline design of the thermal blocking filters for the X-IFU detector on board ATHENA
2014
ATHENA is an advanced X-ray observatory designed by a large European consortium to address the science theme "Hot and Energetic Universe" recently selected by ESA for L2 – the second Large-class mission within the Cosmic Vision science program (launch scheduled in 2028). One of the key instruments of the mission is the X-ray Integral Field Unit (X-IFU), an array of Transition Edge Sensor (TES) micro-calorimeters with high energy resolution (2.5 eV @ 6 keV) in the energy range 0.2÷12 keV, operating at the focal plane of a large effective area high angular resolution (5" HEW) grazing incidence X-ray telescope. The X-IFU operates at temperatures below 100 mK and thus requires a sophisticated c…

C4 plant isotopic composition (delta13C) evidence for urban CO2 pollution in the city of Cotonou, Benin (West Africa).
2006
9 pages; International audience; The carbon isotopic composition (delta13C) of plants can reveal the isotopic carbon content of the atmosphere in which they develop. The delta13C values of air and plants depend on the amount of atmospheric fossil fuel CO2, which is chiefly emitted in urban areas. A new indicator of CO2 pollution is tested using the delta13C variation in a C4 grass: Eleusine indica. A range of about 4 per thousand delta units was observed at different sites in Cotonou, the largest city in the Republic of Benin. The highest delta13C values, from -12 per thousand to -14 per thousand, were found in low traffic zones; low delta13C values, from -14 per thousand to -16 per thousan…
Insights into the effect of soil pH on N(2)O and N(2) emissions and denitrifier community size and activity.
2010
ABSTRACT The objective of this study was to investigate how changes in soil pH affect the N 2 O and N 2 emissions, denitrification activity, and size of a denitrifier community. We established a field experiment, situated in a grassland area, which consisted of three treatments which were repeatedly amended with a KOH solution (alkaline soil), an H 2 SO 4 solution (acidic soil), or water (natural pH soil) over 10 months. At the site, we determined field N 2 O and N 2 emissions using the 15 N gas flux method and collected soil samples for the measurement of potential denitrification activity and quantification of the size of the denitrifying community by quantitative PCR of the narG , napA ,…
