An early assessment of national allocation plans for phase 2 of EU emission trading
Based on 18 National Allocation Plans (NAP) for phase 2 (2008-2012) of the EU Emission Trading Scheme (EU ETS), we explore to which extent individual Member States (MS) intend to use the ETS effectively and efficiently to reduce CO2 emissions. Our analyses at the macro level of these NAPs show that on average the ET-budgets in phase 2 are only about 3 % lower than the budgets in phase 1 (2005-2007), historical emissions in 2005 and projected emissions in 2010. While on average, the old MS intend to reduce emissions by about 10 %, compared to projected emissions, the im-plied excess allocation in the new MS is more than 20 %. When compared with a cost-efficient split of the required emission reductions, the ET-budgets in the EU-15 MS are generally too large. Thus, the burden for non-trading sectors (households, tertiary and transport) will be too high. Noteworthy are also the high shares of governments' intended and companies' possible use of Kyoto Mechanisms, which challenge the traditional position held by the EU on supplementarity. In general, our analyses at the micro level of the allocation methods (across countries and phases) suggest that MS tend to stick with the oncepts and methodologies developed in phase 1, unless these actually contradict rulings by the European Commission. Thus the progress made towards more efficient and more harmonized allocation rules is generally small. With some variation, all NAPs include persistent inefficient rules for closures and new installations which distort dynamic innovation incentives and tend to preserve existing production structures. Observed improvements include a (rather small) increase in auctioning and the use of benchmarking for existing and new installations. Also, the NAPs of a few old MS have simplified special provisions for process-related emissions or combined heat and power. In contrast, new MS have often introduced such provisions in phase 2. We conclude that potentials to improve environmental effectiveness and economic efficiency are far from being tapped. Improvements crucially hinge on the outcome of the European Commission's review process. --
Incentives for energy efficiency in the EU Emissions Trading Scheme
This paper explores the incentives for energy efficiency induced by the European Union Emissions Trading Scheme (EU ETS) for installations in the energy and industry sectors. Our analysis of the National Allocation Plans for 27 EU Member States for phase 2 of the EU ETS (2008-2012) suggests that the price and cost effects for improvements in carbon and energy efficiency in the energy and industry sectors will be stronger than in phase 1 (2005-2007), but only because the European Commission has substantially reduced the number of allowances to be allocated by the Member States. To the extent that companies from these sectors (notably power producers) pass through the extra costs for carbon, higher prices for allowances translate into stronger incentives for demand- side energy efficiency. With the cuts in allocation to energy and industry sectors these will be forced to greater reductions, thus the non-ET sectors like household, tertiary and transport will have to reduce less, which is more in line with the cost-efficient share of emission reductions. The findings also imply that domestic efficiency improvements in the energy and industry sectors may remain limited since companies can make substantial use of credits from the Kyoto Mechanisms. The analysis of the rules for existing installations, new projects and closures suggests that incentives for energy efficiency are higher in phase 2 than in phase 1 because of the increased application of benchmarking to new and existing installations and because a lower share of allowances will be allocated for free. Nevertheless, there is still ample scope to further improve the EU ETS so that the full potential for energy efficiency can be realized. --Climate policy,emission trading,energy efficiency,innovation
(E)-3-(2-Chlorophenyl)-1-(4,4′′-difluoro-5′-methoxy-1,1′:3′,1′′-terphenyl-4′-yl)prop-2-en-1-one
The title compound, C28H19ClF2O2, is a polysubstituted terphenyl derivative bearing a Michael system in which the C=C double bond has an E conformation. In the crystal, C—H⋯Cl and C—H⋯O contacts connect the molecules into layers lying perpendicular to the a axis. The shortest intercentroid distance between symmetry-related 4-fluorophenyl groups is 3.7547 (16) Å
First results of the CERN Resonant WISP Search (CROWS)
The CERN Resonant WISP Search (CROWS) probes the existence of Weakly
Interacting Sub-eV Particles (WISPs) like axions or hidden sector photons. It
is based on the principle of an optical light shining through the wall
experiment, adapted to microwaves. Critical aspects of the experiment are
electromagnetic shielding, design and operation of low loss cavity resonators
and the detection of weak sinusoidal microwave signals. Lower bounds were set
on the coupling constant GeV for axion like
particles with a mass of eV. For hidden sector photons, lower
bounds were set for the coupling constant at a mass
of eV. For the latter we were probing a previously
unexplored region in the parameter space
Multi-layer atom chips for versatile atom micro manipulation
We employ a combination of optical UV- and electron-beam-lithography to
create an atom chip combining sub-micron wire structures with larger
conventional wires on a single substrate. The new multi-layer fabrication
enables crossed wire configurations, greatly enhancing the flexibility in
designing potentials for ultra cold quantum gases and Bose-Einstein
condensates. Large current densities of >6 x 10^7 A/cm^2 and high voltages of
up to 65 V across 0.3 micron gaps are supported by even the smallest wire
structures. We experimentally demonstrate the flexibility of the next
generation atom chip by producing Bose-Einstein condensates in magnetic traps
created by a combination of wires involving all different fabrication methods
and structure sizes.Comment: 4 pages, 5 figure

−·C7H6O3, is a co-crystal from 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium, salicylate anion and salicylic acid in a 1:1:1 ratio. In addition to an intramolecular O—H⋯O hydrogen bond, the crystal packing shows hydrogen bonds between the piperazinium cation and salicylate anion (N—H⋯O), as well as between the salicylic acid molecule and anion (O—H⋯O), giving rise to a three-dimensional network
