The market is demanding for green production and products
Over 100 billion euros will be invested in Italy to the
latest requirement of the 2020 European Policy (IEFE-
Bocconi 2009)
To restart economic growth towards low-carbon ecnomy
…investements for low carbon technologies and markets will
be the 4% of the world GDP within 18 months (Leeds
University 2009)
“The world has its best chance in decades to make serious
progress on both the climate and economic fronts” (Ban
Ki-moon-United nations 2009)
The main bank gorpu in the owrld are working togheter to set
specific investments fund for those companies that are
working for cleaner production and consumption(CDP,2009)
The Green Consumer profile
“Despite of ecnomic crisis, the green products
market share is growing fast to 62%. Conusmers seems to pay even more attention when looking at
social responsibility. ” Carbon Trust 2009

Risks related to resource availability
•Physical Risks: access to water resources and water related services.
•Compliance Risks: regulation and administrative procedures
•Market Risks: Corporate Responsability and reputation
•Financial Risks: water and energy costs rising, fall in sells and profits as a consequence of above mentioned risks
COMPANIES NEED TOOLS TO ASSESS AND MANAGE ENVIRONMENTAL IMPACTS RELATED TO WATER

ISO standards
An International Standard consists in a set of requirements used to accomplish a task in a consistent manner recognized at international level
ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards
Main characteristics:
•Result from a transparent and consesus-based process
•Based on principles of transparency, openess, impartiality and voluntariety
•Voluntary Application

Life Cycle Approach
Look at products, processes and services with a cradle to gate approachin order not to shift impacts from one stage of the life cycle to another!
FROM CRADLEFROM CRADLE
TO GRAVETO GRAVE
The very firts analysis are from the 1969 when
Coca Cola wanted to understand which was
the best packaging for its drink
Glass? Plastic? or Alluminium can?
which of this material is the best for reuse at the
end of life?
Which is the best management strategy at the
end of life of the product?
Reuse? Disposal?

Carbon footprint: a measure expressed in CO2
equivalent to represent the impacts of a product,
a process on climate change
1)It is not a comprehensive assessment but focused
only on climate change
2)Results of an LCA related to climate change
category and of a Carbon Footprint are the same but
are reported differently

What is a Water Footprint?
…integrated by Hoekstra in 2002…
Comprehensive indicator of freshwater resources appropriation. Products, Nation,
Population
(Hoekstra et al., 2011)
Evolved with the support of the Life Cycle Assessment community.
Metric(s) that quantify(ies) the potential environmental impacts related to water (ISO
14046/DIS2). Products, Processes, Organization.
The concept of Virtual Water was firstly introduced by Allan in the 90’s…
Water needed for the production of a product…global trade of embedded water into products.

Data refer to a 15 months period between 2009 and 2010
�Yield of cultivation [26 t/ha]
�Chemical fertilizers used and leaching rate
The two fields are located in the same location and data collected using the same tools
�Climate data (climate station located in the field)
�Primary data of irrigation water volume
�Micro-irrigation is used on both cases
1) Water Accounting
The organic farming method in this case study resulted to be more water intensive than the non-organic one. This result strongly depends on
the yield of the two farming methods in the specific production site.

Conclusions
I. In the specific case study the Organic strawberry farming resulted in higher water use than non-organic strawberry farming per kg of strawberry. The main reason is the different yields of the two farming methods.
I. The Product Water Footprint of the 330g organic strawberry jam is 88.4 l.
II. Overheads water footprint contribution resulted to be over 10%.
III. Ancillary materials and processes should be considered when looking at strategies to reduce a product water footprint.
IV. Other studies in other location will be performed to test the validity of the results;
V. Assessemnet methodology need to be improved to be comprehensive
