Consumers' biased perceptions of the environmental impact of products:influence on advertising efficiency

This paper investigates the main perceptual biases developed by consumers regarding the environmental impact of products. It shows that these biases make consumers unable to distinguish between advertisements for highly versus less sustainable products, but that the inclusion of relevant information can increase the efficiency of arguments for true sustainability.

The impact on agriculture of the drawdown of shallow watertables

The promoters of the large groundwater developments implemented in the 1970's paid little attention to the effects of pumping on soil moisture. A field study, conducted in 1979 in the Tern Area of the Shropshire Groundwater Scheme, revealed that significant quantities of the available moisture could be removed from the root zone of vegetation when drawdown of shallow watertables occurred. Arguments to this effect, supported by the field study evidence, were successfully presented at the Shropshire Groundwater Scheme public inquiry. The aim of this study has been to expand the work which was undertaken in connection with the Shropshire Groundwater Scheme, and to develop a method whereby the effects of groundwater pumping on vegetation can be assessed, and hence the impacts minimised. Two concepts, the critical height and the soil sensitivity depth, formulated during the initial work are at the core of the Environmental Impact Assessment method whose development is described. A programme of laboratory experiments on soil columns is described, as is the derivation of relationships for determining critical heights and field capacity moisture profiles. These relationships are subsequently employed in evaluating the effects of groundwater drawdown. In employing the environmental assessment technique, digitised maps of relevant features of the Tern Area are combined to produce composite maps delineating the extent of the areas which are potentially sensitive to groundwater drawdown. A series of crop yield/moisture loss functions are then employed to estimate the impact of simulated pumping events on the agricultural community of the Tern Area. Finally, guidelines, based on experience gained through evaluation of the Tern Area case study, are presented for use in the design of soil moisture monitoring systems and in the siting of boreholes. In addition recommendations are made for development of the EIA technique, and further research needs are identified.

Corporate environmental responsibility and accountability:what chance in vulnerable Bangladesh?

Bangladesh has recently been enjoying significant economic growth mainly arising from an export led development strategy. However, in that process its natural environment has been degraded and become more vulnerable in geophysical terms (e.g. environmental pollution). Much of the Bangladeshi population are also vulnerable in socio-economic terms due primarily to widespread poverty. In this context we ask, albeit sceptically, whether there is any chance of holding corporations to account for their environmental responsibilities. Using the notions of vulnerability and ecological rifts we answer this question by providing evidence from published sources and a series of 32 semi-structured interviews with Bangladeshi stakeholder groups. Key findings include, inter alia, corporate reluctance to take responsibility for the environmental impact of their activities. Our interviewees discuss the possibility of a role for mandatory corporate reporting in enhancing corporate accountability and we argue that this is essential if the contradictions and irrationalities of the globalized capitalist system are to be made visible. Achieving such accountability, however, will not be easy due to a lack of political will and the prohibitive costs involved. Incurring such costs could raise the dangerous prospect of Bangladesh losing business to other, less regulated, economies.

Building environmental assessment scheme for residential building in Brunei

Building's construction activities, operation and demolition are increasingly recognised as a major source of environmental impact. One strategy for reducing such impacts is most widely known by the term Building Environmental Assessment (BEA). The research is an attempt to develop a new BEA scheme for residential buildings in Brunei which focussing on identifying BEA indicators that best suit for Brunei environment, social and economy. Studies show that Brunei residential sector needs urgent attention to transform its current consumption rate in more sustainable way. Recent launch of Brunei Green Building Council, mandatory energy efficiency guidelines and declaration of ambitious energy intensity reduction target, a new BEA scheme will help contribute sustainability target in residential sector. However the issues of developing a new BEA schemes using existing methods may face constraints in their effectiveness. In this regard, a consensus-forming technique-Delphi method-helps improve greater communication and gain consensus from experts in the construction industry through series of questionnaires. As a result, the final framework is produced comprises of 7 key categories and 37 applicable criteria that achieved high degree of consensus and importance.
