Environmental policy implementation during the economic crisis: an analysis of European member state ‘leader-laggard’ dynamics

ABSTRACT

The long-standing debate on environmental policy ‘leaders’ and ‘laggards’ lends itself to a new analysis following with the advent of the 2008 economic crisis. This paper, therefore, asks the question to what extent do European Union (EU) member states have the capacity and willingness to implement EU environmental policy amid austerity, budget cuts, and rising costs over the period 2008–2014. Building upon previous studies, 26 interviews with European, Greek and United Kingdom participants and records of environmental infringements, the paper provides a contemporary picture of the environmental policy ‘leader-laggard’ dynamic in Europe. The findings demonstrate that the impact of the economic crisis seems contestable and varies amongst member states, while the reduction in environmental infringements appears to have a link with the decrease in economic activity. Although environmental policy ‘leaders’ maintain patterns of strong implementation, the improved implementation performance of some ‘laggards’ reflects a shift in their implementation patterns amid a period of intense political and economic controversies.     

What Is Source Reduction? A Critique and Comparative Analysis of Polish and American Students

/ Source reduction is recognized as the preferred form of waste management, but its definition is ambiguous. This study proposes four underlying dimensions of the source reduction concept. Source reduction is foremost a preventive activity that reduces the number or extent of environmental impacts. Second, source reduction can prevent both resource consumption and pollution generation impacts. Third, source reduction may be viewed as both a producer and consumer activity. Lastly, it may include frugal and more efficient activities. In surveys exploring these fourdimensions, Polish and American university students evaluated whether 20 activities were examples of source reduction. The American students gave higher ratings to preventive activities over adaptive activities. The Polish students most prominently rated efficient over frugal activities. Factor analysis indicated that both samples identified a group of consumer-based resource conservation activities, with the American students recognizing a cluster of recycling activities. In a separate ranking of environmental protection priorities, the Polish students endorsed pollution prevention, whereas the American students favored both efficient and frugal resource conservation. These findings suggest that the conceptualization of source reduction varies according to contextual factors and that prevention is still an obscure environmental management theme. KEY WORDS: Source reduction; Pollution prevention; Resource conservation; Frugality; Poland     

Preparative and analytical extraction of pigments from brown algae with dimethyl sulfoxide

Dimethyl sulfoxide (DMSO) rapidly extracts much of the chlorophyll c and fucoxanthin from the intact thalli of brown algae. Subsequent extraction by acetone rapidly removes most of the chlorophyll a and -carotene. An analytical procedure for these pigments has been developed, based upon this extraction sequence, followed by partition of the acetone extract between hexane and aqueous acetone. Fucoxanthin and chlorophyll c can be recovered from the DMSO extract and the aqueous acetone phase by extraction into ethyl acetate and subsequent evaporation. The DMSO-acetone extraction sequence is also effective with green algae and a few red algae, although the full scope of the method has not been investigated.     

Health, Environmental and Social Justice

Health is a basic human right. Improving health requires social and environmental justice and sustainable development. The 'health for all' movement embraces principles shared by other social movements--in sustainable development, community safety and new economics. These principles include equity, democracy, empowerment of individuals and communities, underpinned by supportive environmental, economic and educational measures and multi-agency partnerships. Health promotion is green promotion and inequality in health is due to social and economic inequality. This paper shows how health, environmental and economic sustainability are inextricably linked and how professionals of different disciplines can work together with the communities they serve to improve local health and quality of life. It gives examples of how local policy and programme development for public health improvement can fit in with global and national policy-making to promote health, environmental and social justice.     

Spray irrigation of landfill leachate: estimating potential exposures to workers and bystanders using a modified air box model and generalised source term

Generalised source term data from UK leachates and a probabilistic exposure model (BPRISC(4)) were used to evaluate key routes of exposure from chemicals of concern during the spraying irrigation of landfill leachate. Risk estimates secured using a modified air box model are reported for a hypothetical worker exposed to selected chemicals within a generalised conceptual exposure model of spray irrigation. Consistent with pesticide spray exposure studies, the key risk driver is dermal exposure to the more toxic components of leachate. Changes in spray droplet diameter (0.02-0.2 cm) and in spray flow rate (50-1000 l/min) have little influence on dermal exposure, although the lesser routes of aerosol ingestion and inhalation are markedly affected. The risk estimates modelled using this conservative worst case exposure scenario are not of sufficient magnitude to warrant major concerns about chemical risks to workers or bystanders from this practice in the general sense. However, the modelling made use of generic concentration data for only a limited number of potential landfill leachate contaminants, such that individual practices may require assessment on the basis of their own merits.     

Implementation of a continuous-flow stirred bioreactor system in the bioremediation of heavy metals from industrial waste water

The industrial applicability of immobilized non-viable yeast biomass (Saccharomyces cerivisiae) in continuous-flow stirred bioreactors was tested with respect to metal removal from electroplating effluent solutions containing Cu, Cd, Cr, Ni and Zn in excess of the stipulated water quality criteria. Two systems, a dual bioreactor and triple bioreactor system in series, were tested and compared regarding their efficiency of metal removal. The system containing two bioreactors linked in series provided a more efficient solution to the problem. The introduction of a third bioreactor into the system had a marginal effect on the amount of metal removed. Subsequent to treatment within the bioreactors the levels of Cu, Cr and Ni in the effluent complied with the stipulated drinking water quality criteria and, although in excess of these criteria only 18% of the initial Zn and 17% of the Cd remained in solution.     

A computer simulation study of stochastic models to investigate the population dynamics of the screech owl (otus asio) under increased mortality

The work reported in this paper complements an earlier study in which deterministic models were used examine the effects of additional mortality imposed on a Screech Owl, Otus asio, population. Interest lay in the compensatory mechanisms that the owls might be able to adopt in their population dynamics to counteract the overall effect of the additional mortality imposed, in particular when only a part of the population is affected. Stochastic models are used here to address the same questions, and to give more detailed information about the likely behaviour of the owl population than the information an average sizes provided by the deterministic approach.     

A Model of the Thermal Bar in the Rotating Frame Including Vertically Non-Uniform Heating

Small bottom slope, inviscid solutions are found for a model of the temperature and circulation structure of the thermal bar system. This model includes Coriolis effects, a vertically non-uniform heat input and is axisymmetric. The model also includes general topography and time dependent heating. These solutions include inertial oscillations that have a significant effect on the circulation, especially for the case when the heating is instantaneously applied.     

Genetic evidence of cryptic speciation within hammerhead sharks (Genus Sphyrna)

Surveys of genetic variation within cosmopolitan marine species often uncover deep divergences, indicating historical separation and potentially cryptic speciation. Based on broad geographic (coastal eastern North America, Gulf of Mexico, western Africa, Australia, and Hawaii) and temporal sampling (1991–2003), mitochondrial (control region [CR] and cytochrome oxidase I [COI]) and nuclear gene (lactate dehydrogenase A intron 6 [LDHA6]) variation among 76 individuals was used to test for cryptic speciation in the scalloped hammerhead, Sphyrna lewini (Griffith and Smith). CR and COI gene trees confirmed previous evidence of divergence between Atlantic and Indo-Pacific scalloped hammerhead populations; populations were reciprocally monophyletic. However, the between-basin divergence recorded in the mtDNA genome was not reflected in nuclear gene phylogenies; alleles for LDHA6 were shared between ocean basins, and Atlantic and Indo-Pacific populations were not reciprocally monophyletic. Unexpectedly, CR, COI, and LDHA6 gene trees recovered a deep phylogenetic partition within the Atlantic samples. For mtDNA haplotypes, which segregated by basin, average genetic distances were higher among Atlantic haplotypes (CR: D _HKY=0.036, COI: D _GTR=0.016) than among Indo-Pacific haplotypes (CR: D _HKY=0.010, COI: D _GTR=0.006) and approximated divergences between basins for CR (D _HKY=0.036 within Atlantic; D _HKY=0.042 between basins). Vertebral counts for eight specimens representing divergent lineages from the western north Atlantic were consistent with the genetic data. Coexistence of discrete lineages in the Atlantic, complete disequilibrium between nuclear and mitochondrial alleles within lineages and concordant partitions in genetic and morphological characters indicates reproductive isolation and thus the occurrence of a cryptic species of scalloped hammerhead in the western north Atlantic. Effective management of large coastal shark species should incorporate this important discovery and the inference from sampling that the cryptic scalloped hammerhead is less abundant than S. lewini, making it potentially more susceptible to fishery pressure.     

Quantifying the Impact of Corporate Environmental Performance on Shareholder Value

This article demonstrates an approach for analyzing and communicating the financial implications of a company's environmental exposures. In environmentally sensitive industries, this approach can help companies to benchmark themselves against rivals, to identify major sources of environmental risk and opportunity, to assign financial values to risk‐mitigating options, and to communicate their environmental strategies to the investment community and other stake‐holders. © 2000 World Resources Institute.
