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

PLENARY SESSION 1: FOOD 8 th Int. Conference on LCA in the
Agri-Food Sector, 1-4 Oct 2012
3. Results
For all indicators the results show strong variation between the genders. Even if the physiologically different
consumption amounts among men and women are levelled out on the basis of 2,000 kcal person -1 day -
1 , men still show a higher impact in terms of GWP (CO2e +8%), ammonia emissions (+14%), land use
(+11%), P use (+10%) and CED (+2%). In contrast, women demonstrate a higher water demand (+18%;
Table 4 and Fig. 1). These differences are primarily caused by a higher share of meat products and butter in
the usual diet of men as well as more fruit, vegetables and nuts & seeds in the typical diet of women.
