An integrated environmental indicator for urban transportation systems: description and application
2015
A simplified version of the ecological footprint method is proposed for assessing the environmental performances of urban transportation systems. The method, starting from the knowledge of the composition of the running vehicular fleet, is here applied to a southern Italian province. It represents a synthetic indicator of the environmental pressure exerted by the system also matching the pollutant emissions with the carrying capacity of the site. Particularly, the forested area needed to absorb the CO2 emissions of the system is compared with the total forested area of the province. The results of the case-study indicates the yearly maximum distance that each vehicle of the fleet can cover …

The composition of phytoplankton community is the basis for environmental monitoring and assessment of the ecological status of aquatic ecosystems. Community composition studies of phytoplankton have been based on time-consuming and expertise-demanding light microscopy analyses. Molecular methods have the potential to replace microscopy, but the high copy number variation of ribosomal genes and the lack of universal primers for simultaneous amplification of prokaryotic and eukaryotic genes complicate data interpretation. In this study, we used our previously developed directional primer-independent high-throughput sequencing (HTS) approach to analyze 16S and 18S rRNA community structures. C…

The sustainability report in the the NPOs. An innovative model
2014
The growing attention toward sustainability report pushed companies, private and public as well, to adopt instruments able to rate sustainability and environmental impact. Many tools can be used to evaluate social communication but the sustainability report is the most complete to explore, measure, understand and communicate the results under this aspect. Through the sustainability report is possible to supply a balanced vision of the sustainability performance of an organization and to understand all the positive and negative effects generated running the activity. To report the activity NPOs as well, has to disclose results and their connection with the surrounding community as social, en…
Strategic Environmental Analysis (SEA) of the building Sector: an Annotated List of Indicators and a Simple Methodology
2003
With respect to the SEA of the town planning scheme of the Sicilian region, we will analyse through the paper the most commonly adopted indicators of sustainability and we will select the most promising of them for the purpose. Moreover, a simplified approach will be introduced for the assessment of the SEA by utilising both simple and aggregate indicators: simple indicators (selected among those proposed in the literature) will lead to the “technical” assessment of the SEA, while aggregate indicators (built up by properly grouping the simple ones) will lead to the “political” assessment of the Sicilian urbanistic sector. Simple indicators will refer to official data, essentially concerning…
Applying a new synthetic environmental indicator to urban transportation scenario
2002
Through this work will be presented a suitably modified version of a simple model devoted to the evaluation of pollutant matters released in urban contexts by the transportation sector. The method, essentially referring to the pollutant emission factors provided within the European "COPERT III" approach, only requires the knowledge of data concerning the running car fleet on the analysed site. The methodology is here utilised for comparing environmental and energy effects of different transportation policies to be adopted in a given urban area. By imposing modal changes to the transportation demand and, consequently, by re-allocating people from cars to public means, the effects on the rele…
