An ISKCON GBC (Governing Body Commission) Resolution from 2019 on Single-Use Plastic 21 2019:
Whereas plastic is often used once off and then thrown away; whereas the lifetime of plastic varies from 50 years to more than 1000 years; whereas plastic contaminates mother earth and her inhabitants; whereas many ISKCON temples use plastic and foam cups, plates, spoons, water bottles, maha-prasadam packages, plastic bags, etc., once-off and then discard them despite there being biodegradable alternatives; whereas Srila Prabhupada states that first, you become conscious and then you become Krishna conscious; whereas there is an increasing awareness in the general public about such issues and ISKCON should set a proper example
Resolved: That ISKCON centers and members are strongly encouraged to not use single-use plastic.
