Public participation in Sustainable Development Planning (SDP) of cities represents significant challenges to governments and private organizations responsible for developing infrastructure. In this study, a regional government used a series of electronic discussion papers and questions to enable online forum discussions and exchanges between 196 participants on the major SDP issues related to city development up to 2030. This study used a rigorous and structured QSR NVIVO analysis of 690 online forum postings to determine the participants' major SDP concerns for the city over a 20-year period. The collective results of the investigation show that future integrated transport networks, higher density residential and commercial land use, and sustainable population growth are still the subject of concern and intense debate among forum participants, SDP experts and the government. The research also demonstrates the capacity of green information and technology systems to serve as important mechanisms for SDP participation and consultation.

The Australian Government has set an ambitious target that at least 20 per cent of Australia's electricity needs will be met by Renewable Energy (RE) sources by 2020. Given the limited use of RE sources for electricity generation, this national Renewable Energy Target (RET) leaves state, territory and municipal governments in a challenging policy position. In this article, we examine the Australian state of Queensland where RE provides approximately 4 per cent of the region's electricity supplies. The research utilizes stakeholder theory to examine the developmental barriers, targets, policies and actions identified by firms and stakeholder organizations in the RE industry sector. The results from our analysis show that RE developments face a range of socio-technical barriers that require timely actions in the areas of financial incentives, infrastructure enhancement, regulation reform, community-centred developments, technology and workforce investments, and information and education programs. Also, in the context of RE planning, while the national RET is the preferred setting, the differences between Queensland's RE installed generation capacity and electricity supply targets require clarification and agreement.
