LCA Food 2012 in Saint Malo, France! - Manifestations et colloques ...

PARALLEL SESSION 4B: DIET 8 th Int. Conference on LCA in the
Agri-Food Sector, 1-4 Oct 2012
Regarding the composition, some differences can also be observed. One notable trend appears: fruits and
vegetables consumption is closely correlated with organic product purchases. As for Dairies, Meat, fish and
eggs, and Ready-made meals purchases, they slightly decrease while the organic product purchases increases.

3.2. Emission of GHG per kg of product overview
Emissions of GHG per kg of product (carbon footprints) used in this study come from publications or
LCA performed during this project, reconstruction via simplified LCA or approximations as explained before.
Table 12 details the origins of the selected values, and their respective shares of basket mass and impact
for French average consumers. If LCAs (exhaustive or simplified) cover the half of the products, they encompass
more than 2/3rd of the global footprint either because of their significant amounts or because of
their high environmental burdens, are covered.

number of product, mass and impact shares and per production modes for the French average consumption
basket (line totals may differ from 100% due to rounding).
