But measuring the environmental impact of one’s product isn’t easy. And, in the case of milk, it may be harder than most.
The Wall Street Journal reported on this Friday.
“Few products demonstrate the messiness of this effort (to measure a product’s environmental impact) more than a simple carton of milk,” The Wall Street Journal article said. “Several studies in various countries have already sought to tally the impact of milk from its production on a farm to the disposal of its carton. In between, the studies try measure such intricacies as the energy used to make the fertilizer to grow feed for the cows, to fuel trucks delivering the milk, and to power refrigerators cooling it in kitchens.”
