Sustainable development in practice

The semi-annual European Environment Sustainable Conference in Aalborg, Denmark brought together from primarily Europe, but also other parts of the world. The Conference focused on sustainability but one panel focused on practical applications for public policy and private industry. The papers from this panel are presented in this special issue of the journal. They cover topics ranging from corporate sustainable programs to government plans including "feed in laws".Some papers are more academic oriented but clearly derived from practical political experiences such as those of the California energy crisis. These theories argue the need for "agile energy systems" whereby regions, cities and communities must have combinations of on-site or distributed energy generation like combined heat and power (CPH) along with central grid power generation. Finally, there is a clear message in all the papers that "market forces" alone do not develop, monitor or even provide "level playing fields" for communities. In short, there needs to be continuous "government" or public involvement in the sustainable communities.
