Effect of the European Union Emission Trading Scheme (EU ETS) on companies: Interviews with European companies

We visited Belgian and Dutch companies that are covered by EU ETS in November 2007, in order to conduct interviews regarding the impact of the scheme and the resultant performance of these companies. The problems of the EU ETS that emerge from this interview are as follows: (1) the redundancy of emission allowance dampens the incentive to reduce the emission of CO2, (2) the allocation scheme fails to consider inter-industrial and/or inter-district fairness, and (3) since the duration of the National Allocation Plan is too short and highly uncertain, it is difficult to implement a long-term reduction investment plan. As European company officers pointed out, the current EU ETS has several problems. However, the recent political debate on the EU ETS seems to have entered a new dimension toward the second period of the National Allocation Plan. For instance, the cap of CO2 emission in the second period has tightened in comparison with the case in the first period, when the allowance excessive. Furthermore, in January 2008, the European Union set the goal of reducing emission by 20% from the 1990 level, by the year 2020. Moreover, the EU intends to introduce the complete auction of emission allowance after the year 2013 excluding the sector that is expected to experience serious leakage problems. The current EU ETS can be regarded as a CO2 reduction scheme in transition. The policy makers of the Japanese government should behold and draw upon the experiences of the European Union in order to implement appropriate policy measures against global warming in Japan.

The Effects of the EU ETS on Companies: Research by Conducting Interviews in European Companies

We study the effects of the European Union Emission Trading Scheme (EU ETS)?which was introduced in January 2005?on companies by conducting interviews in some German and UK firms. In this paper, we demonstrate that although the introduction of the EU ETS has increased awareness of the importance of efforts to reduce global warming and emission costs, it has had little influence on the companies CO2 abatement efforts during the first period.

The Impact of the European Union Emissions Trading Scheme on the Polish Economy:Interviews with Four Companies in Poland

This paper reports the results of interviews with four Polish companies. The results of the interviews shows that Polish companies tend to evaluate the effects of the introduction of EU ETS in 2005 positively: it provided an alternative view that they need considering environment in their business, and that they had much useful information for the improvement of energy losses by measuring it to verify the amount of emissions. However, there are also several negative claims to the EU ETS: auction adopted in the EU ETS from 2013 not only requires purchasing allowances, but also increases production cost due to the rise in the electricity price. Moreover, some of them are concerned that the competitiveness of Poland might be weakened, since it deeply depends on coal.

Real-time Loss Estimation for Instrumented Buildings

Motivation. A growing number of buildings have been instrumented to measure and record earthquake motions and to transmit these records to seismic-network data centers to be archived and disseminated for research purposes. At the same time, sensors are growing smaller, less expensive to install, and capable of sensing and transmitting other environmental parameters in addition to acceleration. Finally, recently developed performance-based earthquake engineering methodologies employ structural-response information to estimate probabilistic repair costs, repair durations, and other metrics of seismic performance. The opportunity presents itself therefore to combine these developments into the capability to estimate automatically in near-real-time the probabilistic seismic performance of an instrumented building, shortly after the cessation of strong motion. We refer to this opportunity as (near-) real-time loss estimation (RTLE). Methodology. This report presents a methodology for RTLE for instrumented buildings. Seismic performance is to be measured in terms of probabilistic repair cost, precise location of likely physical damage, operability, and life-safety. The methodology uses the instrument recordings and a Bayesian state-estimation algorithm called a particle filter to estimate the probabilistic structural response of the system, in terms of member forces and deformations. The structural response estimate is then used as input to component fragility functions to estimate the probabilistic damage state of structural and nonstructural components. The probabilistic damage state can be used to direct structural engineers to likely locations of physical damage, even if they are concealed behind architectural finishes. The damage state is used with construction cost-estimation principles to estimate probabilistic repair cost. It is also used as input to a quantified, fuzzy-set version of the FEMA-356 performance-level descriptions to estimate probabilistic safety and operability levels. CUREE demonstration building. The procedure for estimating damage locations, repair costs, and post-earthquake safety and operability is illustrated in parallel demonstrations by CUREE and Kajima research teams. The CUREE demonstration is performed using a real 1960s-era, 7-story, nonductile reinforced-concrete moment-frame building located in Van Nuys, California. The building is instrumented with 16 channels at five levels: ground level, floors 2, 3, 6, and the roof. We used the records obtained after the 1994 Northridge earthquake to hindcast performance in that earthquake. The building is analyzed in its condition prior to the 1994 Northridge Earthquake. It is found that, while hindcasting of the overall system performance level was excellent, prediction of detailed damage locations was poor, implying that either actual conditions differed substantially from those shown on the structural drawings, or inappropriate fragility functions were employed, or both. We also found that Bayesian updating of the structural model using observed structural response above the base of the building adds little information to the performance prediction. The reason is probably that Real-Time Loss Estimation for Instrumented Buildings ii structural uncertainties have only secondary effect on performance uncertainty, compared with the uncertainty in assembly damageability as quantified by their fragility functions. The implication is that real-time loss estimation is not sensitive to structural uncertainties (saving costly multiple simulations of structural response), and that real-time loss estimation does not benefit significantly from installing measuring instruments other than those at the base of the building. Kajima demonstration building. The Kajima demonstration is performed using a real 1960s-era office building in Kobe, Japan. The building, a 7-story reinforced-concrete shearwall building, was not instrumented in the 1995 Kobe earthquake, so instrument recordings are simulated. The building is analyzed in its condition prior to the earthquake. It is found that, while hindcasting of the overall repair cost was excellent, prediction of detailed damage locations was poor, again implying either that as-built conditions differ substantially from those shown on structural drawings, or that inappropriate fragility functions were used, or both. We find that the parameters of the detailed particle filter needed significant tuning, which would be impractical in actual application. Work is needed to prescribe values of these parameters in general. Opportunities for implementation and further research. Because much of the cost of applying this RTLE algorithm results from the cost of instrumentation and the effort of setting up a structural model, the readiest application would be to instrumented buildings whose structural models are already available, and to apply the methodology to important facilities. It would be useful to study under what conditions RTLE would be economically justified. Two other interesting possibilities for further study are (1) to update performance using readily observable damage; and (2) to quantify the value of information for expensive inspections, e.g., if one inspects a connection with a modeled 50% failure probability and finds that the connect is undamaged, is it necessary to examine one with 10% failure probability

Citizen Science Observation of a Gamma‐Ray Glow Associated With the Initiation of a Lightning Flash

シチズンサイエンスで挑む雷の謎 --宇宙線と雷雲の相互作用は、雷の始まりに影響を与えるのか？--. 京都大学プレスリリース. 2023-07-10.Zeus also plays billiards: Citizen-supported Thundercloud Project may lead to better understanding of lightning's origins. 京都大学プレスリリース. 2023-07-12.Gamma-ray glows are observational evidence of relativistic electron acceleration due to the electric field in thunderclouds. However, it is yet to be understood whether such relativistic electrons contribute to the initiation of lightning discharges. To tackle this question, we started the citizen science “Thundercloud Project, ” where we map radiation measurements of glows from winter thunderclouds along Japan's sea coast area. We developed and deployed 58 compact gamma-ray monitors at the end of 2021. On 30 December 2021, five monitors simultaneously detected a glow with its radiation distribution horizontally extending for 2 km. The glow terminated coinciding with a lightning flash at 04:08:34 JST, which was recorded by the two radio-band lightning mapping systems, FALMA and DALMA. The initial discharges during the preliminary breakdown started above the glow, that is, in vicinity of the electron acceleration site. This result provides one example of possible connections between electron acceleration and lightning initiation
