In general, cartons involve a lot less packaging material in relation to the product they protect. For instance, they’re almost twice as efficient as an egg shell. Their combination of strength and light weight means fewer trucks – and less fuel – are needed to transport them. Less fuel, less space, less energy = less green house gas emissions.

When it comes to filling the cartons, Environmental Product Declarations show that Tetra Pak machines require five times less energy than their plastic counterparts.
