Eco-Kashrut
Eco-Kashrut, also called the Eco-Kosher movement, is a movement to extend the Kashrut system, or Jewish dietary laws, to address modern environmental, social, and ethical issues, and promote sustainability. Eco-Kashrut reflects a trend of Kosher-keeping Jews to eat only food that has been ethically and sustainably produced, and in some cases, also locally sourced. Eco-Kashrut can be expressed in the sharing of sustainable shabbat meals.
Eco-Kashrut is related to Magen Tzedek, a proposed additional certification for food that aims to address health, safety, and other labor issues in food production.
