The nature and form of the urban environment is a critical determinant of the sustainability of our society, as it is responsible directly for a large proportion of consumed energy, and influences indirectly the patterns and modes of energy consumed in everyday activities. We examine the current state of research into the energy and greenhouse gas emissions attributable directly or indirectly to urban form. Specifically, we look at the embodied (construction) and operational energy attributable to the construction, maintenance and use of residential dwellings, and we review the literature on the relationship between urban structure and transport related energy consumption. While there is clear evidence from both intra and inter city comparisons that higher density, transit oriented cities have lower percapita transport energy use, the effect of housing density on residential (in-house) energy use is less clear. More detailed research is needed to examine the relationships between urban form and overall energy use. * Corresponding Author: peter.rickwood@gmail.com (ph: 02 9514 8606) 1 In this article, we discuss delivered energy, primary energy, and greenhouse gas emissions attributable to energy use. We asssume readers are aware of the relationship between these measures.

There is a lack of knowledge about effective implementation of intensification policies. The paper concentrates on the intensification experience of Sydney, Australia, and Toronto, Canada. Historical narratives, which document intensification efforts and outcomes since the 1950s, paint different pictures. For much of the period, Sydney adopted a medium-density strategy sustained by public-sector incentives and regulations. In Toronto, in contrast, the focus has been on high-density developments driven mostly by market trends. Lately, however, the Sydney intensification strategy has shifted to high-density projects. The paper concludes by drawing out findings that are relevant to intensification policies in the selected metropolitan regions and elsewhere: the ubiquity of NIMBY reactions; the importance of senior government involvement because less sensitive to anti-density NIMBY reactions; the possibility of framing intensification strategies in ways that avoid political party confrontation; and the role of major environmental movements in raising public opinion support to intensification.walking and cycling plus associated reductions in air pollution, reduced infrastructure costs, preservation of rural land and meeting the dwelling preferences of the growing cohort of younger childless households and older empty-nesters (Eckdish, 1998;McCrea et al., 2005).

Australian cities exhibit a quality of life arguably among the best in the world, but rapidly expanding populations may soon threaten this status. The burgeoning conurbation of South East Queensland (SEQ) is an example. Recent growth management policies and plans (e.g. South East Queensland Regional Plan and local authority growth management strategies) have sought to curtail urban sprawl through urban footprints, growth management boundaries, urban consolidation, and other measures. The 'density imperative' presented by these collective urban policies affects the sourcing, provision and management of open space in inner-city locales in SEQ which may soon run out of land for parks and urban greenspace. This paper presents results from recent research into the environmental equity dimensions of providing urban greenspace in SEQ. Critiquing the long-entrenched parks-standards approach, the paper offers a 'needs-based' alternative, and considers its utility for SEQ and other fast-growing Australian urban areas. Questioning orthodox planning perspectives about who lives in higher density areas, we argue that local and state governments should look towards a variety of new types of green and open space to meet the needs of existing and future residents living in denser built environments.

Premises associated with commercial sex-including brothels, striptease clubs, sex cinemas, and sex shops-have increasingly been accepted as legitimate land uses, albeit ones whose location needs to be controlled because of assumed 'negative externalities'. However, the planning and licensing regulations excluding such premises from areas of residential land use are often predicated on assumptions of nuisance that have not been empirically substantiated. Accordingly, this paper reports on a survey of those living close to sex industry premises in New South Wales, Australia. The results suggest that although some residents have strong moral objections to sex premises, in general residents note few negative impacts on local amenity or quality of life, with distance from a premise being a poor predictor of residents' experiences of nuisance. These findings are considered in relation to the literatures on sexuality and space given regulation which ultimately appears to reproduce heteronormative moralities rather than respond to genuine environmental nuisances.
