The Local Government Act 1985 provided for the abolition of the Greater London Council and the six Metropolitan County Councils on 1st April, 1986. The Act deals with the transfer of those functions currently exercised by the Greater London Council and the Metropolitan County Councils to existing authorities namely the Local Council of each London Borough and Metropolitan District.

It is undeniable that proper planning of spatial development and local regional policies are paramount to ensure whether a country is prosperous or not. In order to ensure its prosperity, discussion on administrative arrangement, spatial development, and regional policy issues in the Malaysian context will be focused. In addition, the importance of Malaysian major development policies and the authorities responsible for its development and implementation are highlighted, followed by the roles of urban development planning. Lastly, Malaysian regional economic corridors, specifically the Northern Corridor Economic Region, are highlighted to show the emphasis given by the Malaysian Government on regional spatial development issues.

The paper aims to discuss how life cycle assessment can be used in the early stage planning phase of new settlements.

By applying the life cycle methodology on the waste, water and wastewater system of a new carbon‐neutral settlement under planning in Norway, the authors discuss the pros and cons with applying this methodology in an early planning phase.

The LCA methodology enabled the authors to compare suggestions from interdisciplinary planning teams, relate them to the existing systems in Trondheim and provide quantitative results back to the decision‐makers, in this case the municipality. The environmental benefits of implementing alternative solutions in the waste, water and wastewater systems were found to be small.

Data availability and uncertainty can be limitations in the early planning phase.

By applying this methodology, the life cycle environmental impact of different solutions can be assessed at an early planning stage.

Even if life cycle assessment has been used for years in the research community, there is too little experience with applying the methodology in the early planning phase of new projects. This paper discuss how life cycle assessment can be used to compare suggestions from interdisciplinary planning teams, relate them to existing systems and provide quantitative results back to the decision‐makers.

Wastewater treatment plants (WWTPs) have long-time environmental impacts. The purpose of this paper is to assess the environmental footprint of two advanced wastewater treatment (WWT) technologies in a life cycle and sustainability perspective and identify the improvement alternatives.

In this study life cycle-based environmental assessment of two advanced WWT technologies (moving bed biofilm reactor (MBBR) and sequencing batch reactor (SBR)) has been carried out to compare different technological options. Life cycle impacts were computed using GaBi software employing the CML 2 (2010) methodology. Primary data were collected and analysed through surveys and on-site visits to WWTPs. The present study attempts to achieve significantly transparent results using life cycle assessment (LCA) in limited availability of data.

The results of both direct measurements in the studied wastewater systems and the LCA support the fact that advanced treatment has the best environmental performance. The results show that the operation phase contributes to nearly 99 per cent for the impacts of the plant. The study identified emissions associated with electricity production required to operate the WWTPs, chemical usage, emissions to water from treated effluent and heavy metal emissions from waste sludge applied to land are the major contributors for overall environmental impacts. SBR is found to be the best option for WWT as compared to MBBR in the urban context. In order to improve the overall environmental performance, the wastewater recovery, that is, reusable water should be improved. Further, sludge utilisation for energy recovery should be considered. The results of the study show that the avoided impacts of energy recovery can be even greater than direct impacts of greenhouse gas emissions from the wastewater system. Therefore, measures which combine reusing wastewater with energy generation should be preferred. The study highlights the major shortcoming, i.e., the lack of national life cycle inventories and databases in India limiting the wide application of LCA in the context of environmental decision making.

The results of this study express only the environmental impacts of the operation phase of WWT system and sludge management options. Therefore, it is recommended that further LCAs studies should be carried out to investigate construction and demolition phase and also there is need to reconsider the toxicological- and pathogen-related impact categories. The results obtained through this type of LCA studies can be used in the decision-making framework for selection of appropriate WWT technology by considering LCA results as one of the attributes.

The results of LCA modelling show that though the environmental impacts associated with advanced technologies are high, these technologies produce the good reusable quality of effluent. In areas where water is scarce, governments should promote reusing wastewater by providing additional treatment under safe conditions as much as possible with advanced WWT. The LCA model for WWT and management planning can be used for the environmental assessment of WWT technologies.

The current work provides a site-specific data on sustainable WWT and management. The study contributes to the development of the regional reference input data for LCA (inventory development) in the domain of wastewater management.
