- •
The environmental impact of milk in Italy was estimated through Life Cycle Assessment.
- •
Livestock and crop production had a great effect on environmental impact of dairy farms.
- •
Third milking and anaerobic digestion (AD) were assessed as mitigation strategies.
- •
AD strongly reduces acidification, global warming, eutrophication and energy use.
- •
Environmental benefits were found increasing milking frequency from 2 to 3 per day.
