Jens Froese presented the results of the sub-project 2 Ports and Environment at the Green Ports Conference in Naples 24. & 25. February 2009.
The research project EFFORTS (effective operations in ports) is not re-stricted to environmental issues, however, it is understood that the port environment is a crucial production and image factor of a port. Therefore “port environment” is one of the three thematic columns of the project. Energy management, ships’ ballast water, diluted aluminium from ca-thodic protection of port steel constructions, port air quality tackling VOCs and noise annoyance are the key words to describe EFFORTS work related to the port environment. The paper provides a brief overview to explain the course of activities and expected results which will allow ports to strengthen their role as environmental protagonists and to improve trust in residents in the vicinity of ports taking their environmental responsibil-ity very seriously.

WP 2.4. Noise Annoyance of Ports: Outdoor sound propagation
Most of the environmental factors have some effect on sound propagation outdoors. Many of these factors can be properly implemented to a sound propagation model. However, it is not easy to handle sound scattering due to the turbulence, and at the same time, the turbulence is the most important source of uncertainties. Concurrently with the studies of turbulence models we have developed a concept to get an estimate of the excess attenuation using a state-of-the-art physical model and to evaluate the uncertainties using a statistical model. This statistical model is based on two years continuous measurements using extensive acoustical and meteorological measurement facilities and producing over 100 factors hourly. Many meteorological factors had a strong and significant correlation with the excess attenuation, but between each other too. To avoid instable model due to the collinearity many factors were abandoned. In this paper the criterion and methods to select best explaining factors and to form this statistical model are considered.

WP 2.3. Port Air Quality
By Jerome Taranto, BIOWIND, France
Currently sulfur and Volatil Organic Compounds (VOCs) are the main air pollutants from port areas. The sulfur compounds are responsible for acid rains and some of the VOCs are toxic or carcinogenic. The VOC emissions from petroleum roducts loading operations constitute around 1% (140.000 t/a) of all VOC emissions in EU. Solutions exist, but their effi ciency and/or cost can be improved. Therefore the treatment of the port air is necessary for the protection of the environment and health and to improve safety.

WP 2.2 Water Quality
A multidisciplinary approach for the future port environment management and water quality survey
By Samuel Pineau, Corrodys, France
Port environment is probably the highest interface between human activity and marine environment, including the influence of industries, cities, indirect impact from onshore activities such as industry and agriculture, ships and port activities. Click here for full text.
WP 2.1 Clean Energy Management
By Jean Claude Dellinger, AREVA TA, France
In the light of developing countries' legitimate ambitions, industrialised countries will need to reduce their emissions by a factor of 3 to 5 by 2050 to reduce overall greenhouse gas emissions linked to human activity to a level that the planet can recycle naturally by the middle of the century. This is a major challenge in and of itself. It has been made even more difficult for the period in question by a spontaneous trend towards growth in energy demand, even in industrialised countries, and by constant readiness to satisfy most of this demand through accessible fossil energy reserves without an immediate risk of running out.

The response to this challenge, which the economic actors have not yet entirely sized up, will call for changes in behaviour, in regulations and in energy prices, but above all for technological innovations which are essential to maintain, or further improve, standards of living and international competitiveness, the two of which are inextricably linked together.
